Abstract
AIMS This study aimed to investigate the clinical, histological, immunohistochemical and chromosomal features of primary cutaneous adenoid cystic carcinoma (PCACC). METHODS AND RESULTS We retrospectively analysed 13 cases identified on their clinicopathological features and performed fluorescence in-situ hybridisation (FISH) on six available cases. Head and neck (46.2%) were most commonly involved. The median age was 53 years, with a male predilection. Histologically, tumours were classified as grades 1 (eight), 2 (four) and 3 with high-grade transformation (HGT) (one). The HGT component was demonstrated as poorly differentiated carcinoma with multifocal necrosis and myoepithelial differentiation. Patients with one of the following factors: longest diameter of the lesion (≥ 1 cm), involvement of subcutaneous fat tissue and widely infiltrative border had a relatively higher rate of local recurrence, distant metastasis and death. Five of six cases were confirmed to have MYB translocation, while nuclear staining for MYB proto-oncogene, transcription factor (MYB) protein was found in four cases. During the follow-up (median = 64 months), two patients experienced local recurrences. One patient, who was classified as grade III PCACC with HGT, developed multiple metastases and died of disease. Another patient was alive with multiple metastases. CONCLUSIONS This is the largest single-institution study, to our knowledge, of PCACC in an Asian population. We describe the first case of scalp PCACC with HGT, which is the only death case in our series. PCACC tends to recur locally and has metastatic potential. PCACC with HGT has a poor prognosis.

Abstract
A series of 20 cases of pleomorphic adenoma and 19 cases of adenoid-cystic carcinoma of the salivary glands, and one case in the mammary location, were investigated regarding immunohistochemical reactivity for Tissue Polypeptid Antigen (TPA), Pre-Keratins, Vimentin, S-100 Protein, and their arrangement pattern of fibronectin. As a whole, the results support the hypothesis of morpho-structural and mainly, onto-histogenetic similarities between these tumours, but they also underline the need for great care in outlining their morpho-functional features, in relation to their different prognoses.

Abstract
PURPOSE Adenoid cystic carcinoma (ACC) is an indolent salivary gland malignancy, characterized by t(6;9) translocations and MYB-NFIB gene fusions in approximately 50% of the tumors. The genetic alterations underlying t(6;9)-negative and t(6;9)-positive/MYB-NFIB fusion-negative ACC remain unknown. To uncover the genetic alterations in ACC lacking the canonical translocation and fusion transcript and identify new abnormalities in translocation positive tumors. EXPERIMENTAL DESIGN We performed whole-genome sequencing in 21 salivary ACCs and conducted targeted molecular analyses in a validation set (81 patients). Microarray gene-expression data were also analyzed to explore the biologic differences between fusion positive and negative tumors. RESULTS We identified a novel MYBL1-NFIB gene fusion as a result of t(8;9) translocation and multiple rearrangements in the MYBL1 gene in 35% of the t(6;9)-negative ACCs. All MYBL1 alterations involved deletion of the C-terminal negative regulatory domain and were associated with high MYBL1 expression. Reciprocal MYB and MYBL1 expression was consistently found in ACCs. In addition, 5'-NFIB fusions that did not involve MYB/MYBL1 genes were identified in a subset of t(6;9)-positive/fusion-negative tumors. We also delineated distinct gene-expression profiles in ACCs associated with the length of the MYB or MYBL1 fusions, suggesting a biologic importance of the C-terminal part of these fusions. CONCLUSIONS Our study defines new molecular subclasses of ACC characterized by MYBL1 rearrangements and 5'-NFIB gene fusions.

Abstract
Background Salivary adenoid cystic carcinoma (ACC) is a rare relentlessly progressive malignant tumor. The molecular events associated with ACC tumorigenesis are poorly understood. Variable microRNAs (miRNA) have been correlated with tumorigenesis of several solid tumors but not in ACC. To investigate the association of miRNAs with the development and/or progression of ACC, we performed a comparative analysis of primary ACC specimens and matched normal samples and a pooled salivary gland standard and correlated the results with clinicopathologic factors and validated selected miRNAs in a separate set of 30 tumors. Methods MiRNA array platform was used for the identification of target miRNAs and the data was subjected to informatics and statistical interrelations. The results were also collected with the MYB-NFIB fusion status and the clinicopathologic features. Results Differentially dysregulated miRNAs in ACC were characterized in comparison to normal expression. No significant differences in miRNA expression were found between the MYB-NFIB fusion positive and -negative ACCs. Of the highly dysregulated miRNA in ACC, overexpression of the miR-17 and miR-20a were significantly associated with poor outcome in the screening and validation sets. Conclusion Our study indicates that the upregulation of miR-17-92 may play a role in the biology of ACC and could be potentially targeted in future therapeutic studies.

Abstract
Adenoid cystic carcinoma is a malignant neoplasm most commonly originating in the salivary glands of head and neck region. The clinical and pathological findings typical of this tumour include slow growth, perineural invasion and potential local recurrence. Up to 50% of these tumours occur in the intraoral minor salivary glands usually in the hard palate. We present a case report of a 26-year-old woman who was diagnosed with adenoid cystic carcinoma of the right buccal mucosa. The peculiarity of the lesion and the approach we made is the key factor in the presentation.

Abstract
The molecular genetic alterations underlying the development and diversity of salivary gland carcinomas are largely unknown. To characterize these events, comparative genomic hybridization analysis was performed, using a single-nucleotide polymorphism microarray platform, of 60 fresh-frozen specimens that represent the main salivary carcinoma types: mucoepidermoid carcinoma (MEC), adenoid cystic carcinoma (ACC), and salivary duct carcinoma (SDC). The results were correlated with the clinicopathologic features and translocation statuses to characterize the genetic alterations. The most commonly shared copy number abnormalities (CNAs) in all types were losses at chromosomes 6q23-26 and the 9p21 region. Subtype-specific CNAs included a loss at 12q11-12 in ACC and a gain at 17q11-12 in SDC. Focal copy number losses included 1p36.33-p36-22 in ACC, 9p13.2 in MEC, and 3p12.3-q11-2, 6q21-22.1, 12q14.1, and 12q15 in SDC. Tumor-specific amplicons were identified at 11q23.3 (PVRL1) in ACC, 11q13.3 (NUMA1) in MEC, and 6p21.1 (CCND3), 9p13.2 (PAX5), 12q15 (CNOT2/RAB3IP), 12q21.1 (GLIPR1L1), and 17q12 (ERBB2/CCL4) in SDC. A comparative CNA analysis of fusion-positive and fusion-negative ACCs and MECs revealed relatively lower CNAs in fusion-positive tumors than in fusion-negative tumors in both tumor types. An association between CNAs and high grade and advanced stage was observed in MECs only. These findings support the pathogenetic segregation of these entities and define novel chromosomal sites for future identification of biomarkers and therapeutic targets.

Abstract
OBJECTIVE To investigate the molecular genetic heterogeneity associated with the t(6:9) in adenoid cystic carcinoma (ACC) and correlate the findings with patient clinical outcome. EXPERIMENTAL DESIGN Multimolecular and genetic techniques complemented with massive pair-ended sequencing and single-nucleotide polymorphism array analyses were used on tumor specimens from 30 new and 52 previously analyzed fusion transcript-negative ACCs by reverse transcriptase PCR (RT-PCR). MYB mRNA expression level was determined by quantitative RT-PCR. The results of 102 tumors (30 new and 72 previously reported cases) were correlated with the clinicopathologic factors and patients' survival. RESULTS The FISH analysis showed 34 of 82 (41.5%) fusion-positive tumors and molecular techniques identified fusion transcripts in 21 of the 82 (25.6%) tumors. Detailed FISH analysis of 11 out the 15 tumors with gene fusion without transcript formation showed translocation of NFIB sequences to proximal or distal sites of the MYB gene. Massive pair-end sequencing of a subset of tumors confirmed the proximal translocation to an NFIB sequence and led to the identification of a new fusion gene (NFIB-AIG1) in one of the tumors. Overall, MYB-NFIB gene fusion rate by FISH was in 52.9% whereas fusion transcript forming incidence was 38.2%. Significant statistical association between the 5' MYB transcript expression and patient survival was found. CONCLUSIONS We conclude that: (i) t(6;9) results in complex genetic and molecular alterations in ACC, (ii) MYB-NFIB gene fusion may not always be associated with chimeric transcript formation, (iii) noncanonical MYB-NFIB gene fusions occur in a subset of tumors, (iv) high MYB expression correlates with worse patient survival.

Abstract
CONTEXT Although genome-wide imbalances have been characterized in conventional adenoid cystic carcinoma, other than p53 mutational status, the molecular profile of adenoid cystic carcinoma with high-grade transformation has not been explored. OBJECTIVE To evaluate progressive genetic alterations in adenoid cystic carcinoma with high-grade transformation using array comparative genomic hybridization. DESIGN Five adenoid cystic carcinomas with high-grade transformation (4 primary tumors and 1 paired metastasis) were selected and characterized at the DNA level by array comparative genomic hybridization on formalin-fixed paraffin-embedded tissue. Select alterations were validated by fluorescence in situ hybridization. RESULTS Chromosomal gains were mostly confined to the areas of high-grade transformation while losses were seen only in the conventional areas. Chromosomal regions with significant gains included 8q24, 17q11.2-q12, 17q23, and 15q11-13. Regions that showed the significant losses included 9q34, 4p16, 1p36.1, and 11q22. Fluorescence in situ hybridization analysis demonstrated increases in C-MYC (8q24.12-q24.13) and a low level increases in ERBB2 ( formerly HER2/neu ) (17q11.2-q12) in cases showing gains by array comparative genomic hybridization in these regions. However, no tumor showed HER2/ neu immunopositivity. CONCLUSIONS High-grade transformation in adenoid cystic carcinoma is a complex process that is reflected by several chromosomal alterations. Our findings implicate C-MYC amplification in this progression, although the role of HER2/neu is still unclear. Other candidate oncogenes, particularly on chromosome 17q23, warrant investigation in this rare tumor.

Abstract
We present an adenoid cystic carcinoma of the base of tongue in a 48-year-old male with a restricted chromosomal alteration by cytogenetic and spectral karyotypic analysis (SKY). SKY and G-banding analyses identified the t(6;14)(q25;q13) as the sole structural aberration in all metaphases analyzed. This finding supports a critical role for this event in the development of this tumor. The implications of chromosome 6q translocation in this case and in previously reported adenoid cystic carcinomas are highlighted and discussed.

Abstract
Adenoid cystic carcinoma (ACC) is a malignant salivary gland tumor, which shows frequent recurrence and metastasis, ultimately with a poor outcome. We previously demonstrated that p27 down-regulation is frequently found and is due to an enhancement of its degradation in ACC. In this study, we transfected nondegradable p27 mutant (T187A) and wild-type gene into ACC cell line. Transfection of T187A mutant gene was more effective on inhibition of cell growth of ACC cells, suggesting that aberration of p27 degradation may be present in ACC. As F-box protein S-phase kinase-associated protein 2 (Skp2), which is necessary for ubiquitin-mediated degradation of p27, is involved in p27 down-regulation in various cancers, we examined the Skp2 expression and its association with p27 expression in 50 ACC cases. We found Skp2 expression in 36% of ACC cases and inverse association between the expression of Skp2 and p27. Moreover, Skp2 small interfering ribonucleic acid (siRNA) transfection decreased Skp2 protein and accumulation of p27 protein and inhibited the cell growth of ACC cells in vitro. These findings, overall, suggest that Skp2 may play an important role in ACC development through the down-regulation of p27 and that Skp2 siRNA can be a novel modality of cancer gene therapy for suppression of p27 down-regulation in ACC.

Abstract
Minor salivary gland tumors of the buccal vestibule are relatively rare. Adenoid cystic carcinoma is the fifth most common salivary gland malignancy following mucoepidermoid carcinoma, adenocarcinoma not otherwise specified (NOS), acinic cell adenocarcinoma and polymorphous low-grade adenocarcinoma (PLGA). Greater than half of adenoid cystic carcinomas occur in the parotid and submandibular glands. The most common intraoral site is the palate. Adenoid cystic carcinoma tends to have a protracted clinical course with wide infiltration and late distant metastases. We present a case of an adenoid cystic carcinoma of the buccal vestibule in a 59-year-old Caucasian female patient that she had been aware of for 15 years.

Abstract
Adenoid cystic carcinoma (ACC) is one of the most common malignant tumors of the salivary glands. It tends to grow slowly but is associated with a poor prognosis compared to other malignant salivary gland tumors. To identify specific markers of ACC, we examined protein expression profiling in ACC xenograft and normal salivary glands (NSG) using fluorescent 2-dimensional differential in-gel electrophoresis (2-D-DIGE), an emerging technique for comparative proteomics, that improves the reproducibility and reliability of differential protein expression analysis between the samples. To identify the proteins, matrix-assisted laser desorption/ionization time-of-flight peptide mass fingerprinting was carried out. Using these strategies, we detected 4 upregulated proteins and 5 downregulated proteins in ACC xenograft. Maspin and stathmin were selected for further analyses. Western blotting and immunohistochemical staining showed a higher expression of these proteins in ACC xenograft and clinical ACC tissue compared to NSG. Furthermore, Expression of these proteins was correlated with the histologic grading of ACC (n = 10). Therefore, our data indicate that maspin and stathmin may be not only useful biomarkers of ACC but also markers of biologic behavior in this tumor.

Abstract
Salivary gland carcinomas comprise a rare group of malignant tumors which are difficult to diagnose and treat due to their histopathologic diversity, variable clinical course and anatomic location, particularly with respect to the facial nerve. The present paper summarizes important features of these tumors, including recent advances in their management, i.e., diagnosis, surgery of the primary tumor, neck dissection, radiation therapy, and updates risk factors, criteria of malignancy, and prognostic variables, taking into account the relevant literature. Additionally, the present paper highlights briefly the survival rates of patients suffering from salivary gland carcinomas. The present overview is divided into two parts: the first is focused on epidemiology, etiology, criteria of malignancy, prognostic factors, and tumor classification, while part II discusses the diagnosis and therapy of salivary gland carcinomas.

Abstract
Adenoid cystic carcinoma (ACC) is an indolent tumor that pursues a protracted clinical course with recurrences and late metastases. The aim of this study was to investigate immunohistochemically the expression of p53, bcl-2 protein, and Ki-67 in 21 cases of ACC of the palate, all with a minimum of 10 years and a maximum of 22 years of clinical follow-up. These results were also analyzed with regard to different clinical prognoses of the histologic subtypes of ACC. High expression of p53 and bcl-2 was noted in 19 out of 21 ACC cases (90%), in which most tumor cells (from 66% to 99%) proved to be immunopositive. A relation to the histologic types, clinical staging, and survival was not found. Therefore, the high immunoreactivity against these oncoproteins in the same tumor cells suggests that these two oncogenes may be involved since the early stage of carcinogenesis. Loss of function of the p53 protein combined with bcl-2 upregulation might give the tumor cells a double growth advantage, because uncontrolled proliferation is combined with a reduced cell death rate. The interaction with other oncogenes may then trigger a multistep process able to promote tumor progression. The low labeling index Ki-67 was detected in nine out of 21 cases (42%), with a low percentage of tumor cells (from 3% to 15%) being positive, whereas the remaining 12 cases were negative. We found no relation to the histologic types, clinical staging, and survival; however, the low proliferation rate could explain the natural course of tumor.

Abstract
Adenoid cystic carcinoma is a malignant tumor of salivary gland origin. It tends to grow slowly, but shows frequent recurrence and metastasis. Cyclin D1, a cell-cycle regulation protein, has been reported to be overexpressed in various types of cancer and to correlate with poor survival of the patients. However, the prognostic significance of cyclin D1 expression in ACC of the salivary glands has not yet been determined. To evaluate the role of cyclin D1 in the biological regulation of ACC, we constitutively expressed an antisense cyclin D1 complementary DNA (cDNA) in an established ACC cell line that exhibits high endogenous expression of cyclin D1. The effect of cyclin D1 expression on in vitro cell growth and cell cycle were examined. In addition, we also examined the immunohistochemical expression of cyclin D1 protein in 31 cases of ACC of the salivary gland and correlated its expression with proliferative activity or prognosis. There were no significant differences of the in vitro growth and in the percentage of the total cell population in the G1 phase and S phase between antisense cyclin D1 clones and control clones. Thirty-two percent of tumors derived from surgical specimens examined were immunohistochemically positive for cyclin D1 protein. No association was found between cyclin D1 expression and cell proliferation or the clinical outcome of the patients. It is concluded that cyclin D1 overexpression alone does not induce a marked increase in the proliferative activity of ACC cells and that expression of this protein is not linked to poor prognosis in adenoid cystic carcinoma of the salivary gland.

Abstract
OBJECTIVES/HYPOTHESIS Adenoid cystic carcinoma of the head and neck (ACCHN) is characterized by late recurrence and frequent distant metastasis. Tumor attack by cytotoxic T lymphocytes and macrophages is mediated by the interaction of leukocyte function-associated antigen (LFA)-1 on lymphocytes with intercellular adhesion molecule (ICAM)-1 on the tumor surface. Thus, the reduced expression of ICAM-1 on tumor cells could contribute to their escape from host immune surveillance. To investigate the relationship between the clinical features of ACCHN and host immune surveillance, the expression of ICAM-1 and infiltration of T/natural killer (NK) cells and macrophages were immunohistochemically examined. STUDY DESIGN Retrospective analysis of immunohistochemical tumor characteristics and clinical outcome. METHODS Immunohistochemical study of ICAM-1, T/NK cells, and macrophages was performed on paraffin sections of 42 patients with ACCHN. The expression of T/NK cells and macrophages was represented by T-cell-restricted antigen (TIA)-1 and CD68 expression, respectively. The expression of these molecules and clinical features were analyzed. RESULTS Of 42 ACCHN cases, 15, 9, and 15 patients were classified as ICAM-1 high, TIA-1 high, and CD68 high, respectively. The TIA-1 expression scores in ICAM-1-low patients were significantly lower than those in ICAM-1-high patients (1.3 +/- 3.7 vs. 8.3 +/- 12.7, P =.0031). The CD68 expression scores in ICAM-1-low patients were also significantly lower than those in ICAM-1-high patients (9.6 +/- 9.6 vs. 21.1 +/- 17.6, P =.0047). Moreover, ICAM-1-high patients had a significantly better disease-free survival rate (P =.043). CONCLUSIONS Reduced expression of ICAM-1 may promote immune evasion and metastasis, resulting in poor prognosis in ACCHN.

Abstract
BACKGROUND The clinical significance of perineural invasion of gallbladder carcinoma remains unclear. The aim of this study was to elucidate the incidence and mode of perineural invasion of gallbladder carcinoma and clarify its prognostic significance. METHODS A clinicopathological study was conducted on 68 patients who underwent attempted curative resection for gallbladder carcinoma. According to the pathological tumour node metastasis (pTNM) classification of the Union Internacional Contra la Cancrum, there were five (7 per cent), nine (13 per cent), 20 (29 per cent) and 34 (50 per cent) patients with pT1, pT2, pT3 and pT4 disease respectively. Twenty patients (29 per cent) had pM1 disease, including involved para-aortic nodes, liver metastases and localized dissemination. RESULTS The overall incidence of perineural invasion was 71 per cent (48 of 68 patients). Forty-four (96 per cent) of 46 patients with extrahepatic bile duct invasion had perineural invasion. Although several histological factors were associated with perineural invasion, multivariate analysis demonstrated that extrahepatic bile duct invasion was the only significant factor correlated with perineural invasion (odds ratio 99.0, P < 0.001). The perineural invasion index, defined as the ratio of the number of involved nerves to the total number of nerves examined, was significantly higher at the centre than in the proximal and distal parts of the tumour in the 46 patients with extrahepatic bile duct invasion (P < 0.001). The 5-year survival rate for patients with perineural invasion was significantly lower than that for patients with no invasion (7 versus 72 per cent; P < 0.001). Cox proportional hazard analysis identified perineural invasion (relative risk (RR) 5.3, P < 0.001) and lymph node metastasis (RR 2.5, P = 0.008) as significant independent prognostic factors. CONCLUSION Perineural invasion is common in advanced gallbladder carcinoma and has a significant negative impact on patient survival.

Abstract
BACKGROUND Adenoid cystic carcinoma (ACC) of the salivary gland shows a variable clinical course. It would be helpful to discover reliable biologic markers in the management of patients with ACC. METHODS We examined proliferating cell nuclear antigen (PCNA) and c-erbB-2 oncoprotein expression on 30 cases of ACC of the salivary glands. The immunohistochemical results, and size, location, and histologic grade of the tumors were compared with the clinical outcome of the patients. RESULTS Mean PCNA positivity of ACCs was 15%, and was higher in solid than in cribriform/tubular areas. High PCNA value was significantly correlated with shorter disease-free and overall survival of the patients with ACC. c-erbB-2 overexpression was observed in only five cases, focally in cribriform/tubular areas. High histologic grade, which was determined by the presence of solid components, showed a trend toward shorter survival. Size and location of ACC were not associated with patient outcome. CONCLUSIONS The present study indicates that PCNA score may be one of the most useful prognostic factor of ACC.

Abstract
OBJECTIVE It is well known that adenoid cystic carcinoma (ACC) arising from salivary glands shows a correlation between prognosis and histological growth patterns. The aim of the study was to evaluate whether three growth patterns of ACC are related to the distributions of apoptosis-induced and -suppressed tumor cells. MATERIALS AND METHODS We examined 77 cases of ACC including tubular (18 cases), glandular (50) and solid (9) patterns. In order to visualize the apoptotic cells, terminal deoxynucleotidyl transferase (TdT)- mediated dUTP-biotin nick end labeling (TUNEL) and avidin-biotin complex staining using Lewis Y (LeY) antibody were applied to paraffin sections. For detection of the apoptosis-suppressed cells, immunohistochemistry employing bcl-2 antibody was utilized. RESULTS Apoptosis index (AI) based on the TUNEL-stained specimens were tubular, 7.0; glandular 2.4; solid, 5.1. In tubular type, apoptotic cells were frequently located in the inner tubular layer rather than the outer layer. Solid type had scattered apoptotic cells in the nests. Bcl-2 expression was found in 61% of tubular, 20% of glandular and 22% of solid cases. The localization of bcl-2 protein was noticed in outer tubular cells, and peripheral cells or undifferentiated cells in solid pattern. CONCLUSIONS The peculiar distribution of apoptotic cells may result from the various proportions and distinctive arrangement of neoplastic ductal cells and neoplastic myoepithelial cells in ACC. Apoptotic cells and bcl-2 positive apoptosis-suppressed cells may participate in the construction of characteristic histological appearances of ACC.

Abstract
Immunohistochemical detection of cell proliferation-associated antigens was investigated in 28 cases of adenoid cystic carcinoma (ACC) and 20 cases of pleomorphic adenoma (PA), using antibodies against DNA topoisomerase type II alpha (topo-II) (Ki-S1) and Ki-67 (MIB-1). The correlation of staining indices with clinicopathological data, histological features and prognosis was also studied. The topo-II value was significantly higher in ACC than in PA (P<0.0001), and highest in the solid growth pattern of ACC. In addition, significant relationships were found between topo-II values and clinical features such as local recurrence, surgical margins, and distant metastases. By log-rank test, the topo-II index was also correlated significantly with patient survival (P<0.01). The values of topo-II index paralleled those of Ki-67 index in ACC, and a correlation coefficient of 0.97 was obtained. Topo-II may be considered an additional marker for estimating the proliferating fraction of cells and for predicting the short-term prognosis for patients with salivary gland tumors.

Abstract
We present the cytogenetic, interphase fluorescence in-situ hybridization (FISH) and DNA content findings in a clinically aggressive adenoid cystic carcinoma (ADCC) of the parotid gland. The tumor manifested diploid chromosomal and DNA content by cytogenetic, interphase FISH and flow cytometry. G-banding analysis revealed inv(5)(p15.2q33) and t(6;15)(q25;q15) as the only structural alterations in all 30 metaphases examined. The limited structural abnormalities found in this recurrent lesion suggest that they may constitute a primary or early event in the development of this tumor. The involvement of 6q region in our tumor and in some of the previously reported ADCC supports the association between this region and the evolution of at least a subset of these tumors.

Abstract
PURPOSE This article reports the results of treatment of 7 histologic types of minor salivary gland carcinoma. PATIENTS AND METHODS Of 256 cases, local excision was used in 194, extended excision in 62, excision accompanied by neck dissection in 98, and surgery with adjunctive radiation therapy or chemotherapy in 101. Forty-five of the 98 neck dissection cases had cervical node metastases. RESULTS Survival rates were analyzed for 233 patients. The 3-year survival rate was (167 of 215) (77.67%), the 5-year survival rate was 134 of 187 (71.76%), and the 10-year survival rate was 79 of 113 (69.91%). CONCLUSIONS These data confirm that surgery is still the mode of choice in the treatment of minor salivary gland carcinoma, but a combination with radiation therapy or chemotherapy is advisable in some patients.

Abstract
Basaloid-squamous carcinoma is a unique and infrequent variant of squamous cell carcinoma with a predilection for occurring in the upper aerodigestive tract. The cardinal diagnostic criteria are the presence of basaloid cells arranged in lobules or cords and a squamous component. Another feature that distinguishes basaloid-squamous carcinoma from conventional squamous cell carcinoma is the development of multiple foci of amorphous, eosinophilic, or mucinous materials among the basaloid tumor cells. It is this feature in basaloid-squamous carcinoma that causes confusion with adenoid cystic carcinoma, especially the solid variant of adenoid cystic carcinoma. To clarify the distinctive features of these two types of tumors, the ultrastructural findings in three basaloid-squamous carcinomas from the head and neck region were compared with three adenoid cystic carcinomas, one from the head and neck region and one each from trachea and bronchus. Widened intercellular spaces, tonofilaments, and replicated basal lamina were present in both types of tumor. However, the ultrastructural features of glandular differentiation were present only in adenoid cystic carcinoma, whereas the ultrastructural features of squamous cell differentiation were present only in basaloid-squamous carcinoma. The distinction between basaloid-squamous carcinoma and adenoid cystic carcinoma is important since basaloid-squamous carcinoma is a clinically aggressive, high-grade form of squamous cell carcinoma, generally with a worse prognosis than adenoid cystic carcinoma.

Abstract
In this study of proliferative activity of adenoid cystic carcinomas (ACCs) with different histological patterns, the argyrophilic staining method of nucleolar organizer regions (AgNORs) was applied to paraffin sections from 25 tumors. Sixteen of the neoplasms showed a mixture of different histological patterns in the same section. The AgNOR numbers in the different histological pattern areas in the same tissue sections of all 16 tumors were lowest in the cribriform, intermediate in the trabecular, and highest in the solid pattern areas. The mean AgNOR number was highest in the solid pattern (3.33 +/- 0.52), and lowest in the cribriform pattern (2.12 +/- 0.43). The results show the order of proliferative activity in the different histological pattern areas of ACC, and explain the previous clinical finding that the prognosis of ACC is poorest in solid pattern ACCs. AgNOR staining appears to be a useful technique for evaluation of the proliferative activity of each histological pattern area of ACC, especially when there are different histological pattern areas in the same tissue section.

Abstract
BACKGROUND A retrospective study was performed on 51 patients with adenoid cystic carcinomas to see whether DNA ploidy, tumor stage, and histopathologic grading correlated with prognosis. METHODS Histopathologic grading was performed according to Szanto et al and DNA content was estimated from archived material using the technique by Hedley et al. RESULTS Thirty-nine tumors were DNA diploid and 12 were DNA aneuploid. Histologic grade III was more often associated with DNA aneuploidy than the lower grades (p = 0.011). DNA ploidy also correlated with clinical stage (p = 0.011). Log-rank analysis and Cox regression analysis of treatment failures revealed significant findings for S-phase value and DNA ploidy. CONCLUSIONS Our results indicate that DNA ploidy estimations, S-phase value, and histologic grading are prognostic factors in adenoid cystic carcinomas. These examinations should therefore be incorporated in the evaluation of patients with adenoid cystic carcinomas.

Abstract
Of 29 reviewed ultrastructural studies of adenoid cystic carcinoma, only 1 mentions the presence of annulate lamellae. The present report describes a 65-year-old woman who presented with an adenoid cystic carcinoma in her left maxillary sinus. At the light microscopic level, most of the connective tissue was loose and myxomatous and contained fine strands, cords, and islands of epithelium that in places had a cribriform pattern. The ultrastructural appearance was similar to that described by others. Two epithelial cell types predominated. The cytoplasm of one type contained mainly ribosomes, and that of the other type also had peripheral microfilaments. Also present were pseudocysts, lumina with microvilli, and replicated basal lamina. In addition, a number of both types of cells contained parallel arrays of cisternae that had regular small pores. These were annulate lamellae.

Abstract
We studied a case of adenoid cystic carcinoma. Cytogenetic analysis was performed on short-term culture, and the karyotype revealed only an abnormal cell line with the following changes: partial trisomy 5q, 6q deletion, monosomy of chromosome 9,der(10)t(10;15), a possible ring chromosome 22, and loss of the Y chromosome. The implication of chromosomes 6 and 9 is considered in relation to the karyotypic evolution of this type of tumor.

Abstract
To evaluate the influence of various clinicopathologic factors on survival, a computer analysis was performed on 70 patients who underwent resection for bile duct carcinoma. Univariate analysis of overall survival involving all the patients identified 10 factors that were associated with a significant outcome: location of primary lesion (p = 0.01), pancreatic invasion (p = 0.004), duodenal invasion (p = 0.005), macroscopic and microscopic vascular involvement (p = 0.009 and p = 0.04), perineural invasion (p = 0.02), lymphatic vessel involvement (p = 0.04), lymph node metastasis (p = 0.02), histologic type (p = 0.02), and depth of cancer invasion (p = 0.04). However, when the interactive effects of these factors were taken into account, the pancreatic invasion and perineural invasion were selected as the two most significant prognostic factors in a multivariate analysis using the Cox stepwise proportional hazards model. The age, sex, size of the tumor, macroscopic type of lesions, hepatic infiltration, serosal invasion, resected surgical margin at the proximal and distal ends, exposed surgical margin, peritoneal dissemination, and hepatic metastasis were not significantly associated with prognosis.

Abstract
Specimens from five cases of adenoid cystic carcinoma of the external auditory canal were studied by immunohistochemical staining, and findings were compared with those from adjacent non-neoplastic tissues containing ceruminous glands. In the ceruminous gland, cytokeratin showed diffuse positive staining, while myoepithelial cells were stained for smooth muscle actin, desmin, S-100 protein and vimentin. The epithelial markers used were cytokeratin, carcinoembryonic antigen and secretory component and stained at various densities the inner cells of the tubular component and duct-lining cells in the cribriform component of tumor tissues. In contrast, the muscular markers, smooth muscle actin and desmin, and the mesenchymal marker, vimentin, were positive in the outer cells of the tubular component and in the cyst-lining cells of the cribriform component. S-100 protein immunoreactivity showed paradoxical results; positive findings occurred in the myoepithelial cells of the ceruminous glands and in the inner cells of the tubular component and duct-lining cells of the cribriform component of the tumor. Present findings demonstrate that adenoid cystic carcinoma of the external auditory canal had dual epithelial and myoepithelial differentiation and can mimic the ceruminous glands of the auditory canal.

Abstract
The nuclear DNA content in the tumor cells of 17 pleomorphic adenomas (PA) and 26 adenoid cystic carcinomas (ACC) was assayed by cytofluorometry to clarify the etiology of the differences in their biological nature. Aneuploidy was found in only two solid-pattern ACC samples; all the other samples had diploid stemlines. With respect to the polyploid cell rate and the S + G2M fraction, the differences between the four histological patterns of PA were not significant. In the ACC, the S + G2M fraction was significantly higher in solid pattern than in cribriform or trabecular pattern tumors, which may indicate that proliferative activity is higher in the solid pattern than in the other two. The polyploid cell rate in ACC was significantly higher in the solid pattern than in the cribriform pattern carcinomas. There was no significant difference in the mean polyploid cell rate between PAs and ACCs. The mean S + G2M fraction was significantly higher in all histological patterns of ACCs than in PAs. These results suggest that proliferative activity is greater in any one of the histological patterns of ACC than in PA. These findings may largely explain the biological differences between the two tumors.

Abstract
Eight cases of adenoid cystic carcinoma were reviewed to determine whether and how the histological features of the tumour vary with the progress of the disease. The tumours were classified by their histological patterns as tubular, cribriform, trabecular or solid. The relative amount of each pattern seen in routine light microscopic sections was calculated histomorphometrically and compared in the primary tumour and recurrent and/or metastatic lesions in the same case. In the early stage, the tubular pattern predominated. Later, the highest percentage shifted to the cribriform, then to the trabecular and finally, in the late stage, to the solid pattern. There was no reverse direction of histological transformation from the solid to the tubular pattern. These results may help to explain previous reports that the tubular pattern usually represents a favourable prognosis, the solid pattern a poor prognosis and the cribriform pattern an intermediate prognosis.

Abstract
Proliferative activity of carcinomas arising from salivary glands was analyzed by enumeration of argyrophilic nucleolar organizer regions (AgNORs). The mean numbers of AgNORs in the various tumors were as follows: mucoepidermoid carcinoma, 2.20; acinic cell carcinoma, 2.51; adenoid cystic carcinoma (ACC), 2.57; carcinoma in pleomorphic adenoma, 1.00 (benign component) and 3.99 (cancer-bearing area); salivary duct carcinoma, 4.49; polymorphous low-grade adenocarcinoma, 3.37; sebaceous carcinoma, 2.57; oncocytic carcinoma, 4.63; adenocarcinoma, 4.53. Cells of most tumors showed heterogeneous activity within the same tumor. In mucoepidermoid carcinoma, the mucous cells had suppressed activity in comparison with the epidermoid cells and intermediate cells. In ACC, the activity of the tumor cells increased according to growth pattern in the order tubular, glandular and solid. In carcinoma in pleomorphic adenoma, vigorous proliferative activity was observed in the malignant component, whereas less active cells were seen in the myxoid or chondroid matrix. AgNOR staining was useful for distinguishing benign from malignant regions in carcinoma in pleomorphic adenoma. Our results suggest that mucoepidermoid carcinoma, acinic cell carcinoma and ACC, except for that with a solid growth pattern, may be considered as low-grade malignancies, whereas solid-type ACC, the cancer component in carcinoma in pleomorphic adenoma and some of the other carcinomas have high-grade malignant behavior.

Abstract
To elucidate the clinical significance of perineural invasion on bile duct cancer, a clinicopathologic study was performed on 70 resected patients with bile duct carcinoma. The overall incidence of perineural invasion in the resected specimen was 81.4%. There seemed to be no correlation between perineural invasion and site, size of the tumor, and lymph node metastasis. A significant correlation was observed, however, between macroscopic type, microscopic type, depth of invasion, and perineural invasion. Perineural invasion index (PNI) was defined as the ratio between the number of nerve fibers invaded by cancer and the total number of nerve fibers with and without cancer invasion. Perineural invasion index was significantly higher at the center compared with the proximal and distal part of the tumor (p less than 0.001). The 5-year survival rate for patients with perineural invasion was significantly lower (p less than 0.05) than that for those without perineural invasion (67% versus 32%).

Abstract
In a group of 245 cases of primary carcinoma of the esophagus the authors found three cases of adenoid cystic carcinoma (ACC). Clinical and pathologic data of those patients (one female and two male; age range, 49-74 years) were analyzed. Tumors were localized in the middle third of the esophagus. One patient lived 15 months after surgery. Another is a case of early ACC who has been living 4.5 years after surgery and is without specific symptoms. The third patient had not had surgery and died 13 months after the onset of dysphagia. An autopsy showed only a locally invasive tumor growing into the surroundings of the esophagus, and regional lymph node metastases without distant parenchymal metastases. These findings support pathologic and biologic similarities between ACC of the esophagus and ACC of the salivary glands. There are synchronous tumors of the esophagus and the vital localization which makes the prognosis of ACC of the esophagus worse than ACC of the salivary glands.

Abstract
This ultrastructural study is based on nine cases of adenoid cystic carcinoma arising from the salivary glands. Electron microscopically, the tumors consisted of five cell types: relatively differentiated intercalated duct cells, secretory cells, undifferentiated cells, cells of a squamous nature, and myoepithelial cells. Special attention was paid to the characteristic extracellular substances noted by light microscopic examination of these tumors. The hyaline material of the pseudocysts contained not only mucopolysaccharide granules but also fingerprint-like structures formed by replicated basement membrane. Some of these structures had a dense core, probably composed of mucopolysaccharide granules. Cell islands surrounded by elasticlike material also were found. The true lumina were usually filled with membranovesicular structures originating from fragments of the lining cells, mainly those with squamous differentiation. These membranovesicular structures included electron-dense rods, filamentous whorls, and structures displaying periodicity.

Abstract
Among adenoid cystic carcinomas of salivary glands (ACCs), the solid basaloid type has a poor prognosis similar to that of undifferentiated adenocarcinomas. We studied 24 cases in immunohistochemistry using antibodies reactive with keratins of various molecular weights, vimentin, S-100 protein, and its A and B subunits. Our findings were correlated with the histological pattern and with the variable degree of differentiation of these carcinomas. In comparison with other types of ACC, intermediate filament proteins in this group were weakly expressed. The co-expression of cytokeratin and vimentin was noted in some cases. Additional features noted were the presence of cribriform cavities associated with solid lobules and areas of necrosis giving a comedocarcinomatous pattern. In these two variants, cells characterized by the dual expression of cytokeratin and S-100 protein were seen. In the highly malignant anaplastic variety, only a few cells were weakly positive with antisera to cytokeratin and vimentin. This group shows similarities to undifferentiated adenocarcinomas of salivary glands. Such similarities could be explained by the common origin of these tumours from intercalated ducts.

Abstract
Immunohistochemical studies were performed to explore the distribution of S-100 protein and its alpha, beta subunits in 76 adenoid cystic carcinomas (ACC) of the salivary glands. Histopathologically. ACC was divided into cribriform, tubular, basaloid and trabecular types which could be mixed in the same tumor. S-100 protein was usually positive in tumor cells forming cribriform structures; foci of strongly positive tumor cells were also distributed in the luminal layer of tubular structures, and in areas transitional between cribriform and tubular patterns. S-100 alpha staining was confined to some tumor cells in cribriform areas, to luminal tumor cells in tubular structures and to few tumor cells in basaloid structures. S-100 beta reaction was usually localized to luminal surfaces in a fine granular pattern in tubular and microtubular structures in a distribution somewhat similar to that in the normal salivary gland. Great heterogeneity in the immunohistochemical distribution of S-100, S-100 alpha and S-100 beta proteins was found in the various histologic types of ACC and the pattern was different from that seen in pleomorphic adenomas. It is possible that the ACC tumor cells positive for S-100 protein may be closely related to true or modified myoepithelial cells.

Abstract
The principles of the proposed modified WHO Histological Typing of Salivary Gland Tumours are based on the following: 1) The classification of tumours is oriented to the routine work of the practicing surgical pathologists, those who do not see tumours of the salivary glands very often. The inclusion of rare, but clearly defined tumour entities should be helpful to surgical pathologists consulting with clinical specialists. 2) The different types of carcinomas must be distinguished not only by precise histopathological definitions, but also considering differences in prognosis and treatment. For example, the polymorphous low-grade adenocarcinoma and the epithelial-myoepithelial carcinoma are characterized by a relatively good prognosis in contrast to the salivary duct carcinoma. 3) Special points of discussion are: subclassification and grading of carcinomas (e.g. acinic cell carcinoma, mucoepidermoid carcinoma and adenoid cystic carcinoma), the classification of basal cell tumours (basal cell adenoma, basal cell carcinoma, solid type of adenoid cystic carcinoma), malignant tumours in pleomorphic adenomas and the differential diagnosis between primary tumours and metastases.

Abstract
Fifty-four adenoid cystic carcinomas (ACC) arising in major and minor salivary glands as well as in normal salivary glands were studied by immunohistochemistry for the presence of vimentin, neuron-specific enolase (NSE), alpha 1-antichymotrypsin (alpha 1-ACT) and alpha 1-antitrypsin (alpha 1-AT). Five patterns of histological differentiation were found in ACC, and for the cellular components of each, it was possible to establish a special immunohistochemical profile. In ACC, vimentin-positive cells were observed in the outer tubular, cyst-lining and small angular cells. NSE was positive in the myoepithelial cells of normal salivary gland. Neoplastic cells of ACC showed NSE positivity mainly in the small angular cells and partly in the duct luminal cells. alpha 1-ACT was localized in the intercalated duct cells and serous acinar cells of normal salivary gland, and in the duct luminal cells of ACC. alpha 1-AT could not be detected in any of the epithelial cells of normal salivary gland. In ACC, eosinophilic hyaline material in the cribriform spaces was positive for alpha 1-AT, but no positivity was demonstrated in tumor cells. The present study showed that there are at least two populations of tumor cells in ACC: duct luminal cells that express alpha 1-ACT, thus indicating their ductal character, and small angular cells that express vimentin, characteristic of non-luminal cells. Moreover, our results indicate that alpha 1-AT is a useful marker of basement membrane-like material.

Abstract
Basaloid-squamous carcinoma, a variant of squamous cell carcinoma, has only recently been described as arising in the pharynx. The cardinal histopathologic feature, as its name suggests, is a biphasic cellular pattern of basaloid and squamous components in an intimate relationship. Major differential diagnoses include adenoid cystic, squamous, adenosquamous, and sarcomatoid carcinomas. Although the number of reported cases is small, basaloid-squamous carcinoma appears biologically virulent, with a propensity to aggressive local behavior and early regional and distant metastasis, and subsequent poor survival. The authors add a further case of basaloid-squamous carcinoma to the world literature.

Abstract
Adenoid cystic carcinoma is a specific variant of adenocarcinoma with a characteristic cribriform appearance. The tumor may arise from salivary glands and various other sites, but the origin and cellular composition of this unique neoplasm have been controversial. A potential use of immunohistochemistry is to provide additional information on the origin of various cellular components of tumors by comparing them with corresponding normal tissues. Immunohistochemical distributions of carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA), keratin, low molecular weight keratin (54 kd), S100 protein, muscle-specific actin, laminin, and type IV collagen were evaluated in 20 adenoid cystic carcinomas arising in major and minor salivary glands. Anti-CEA, anti-EMA, anti-keratin, and anti-S100 antibodies strongly stained cells lining true lumina. Muscle-specific actin, a marker for myoepithelial cells, was found in lining cells of pseudocysts, in tumor cells proper, and in nonluminal cells with a tubular growth pattern. A monoclonal antibody against 54 kd keratin stained almost all cells in the neoplasms. In pseudocysts, replicated basal lamina reacted with antisera to laminin and to type IV collagen. The present study demonstrates that there are at least two populations of tumor cells in adenoid cystic carcinoma: luminal cells that express CEA and EMA, thus indicating their ductal character, and nonluminal cells that express muscle-specific actin characteristic of myoepithelium.
