Abstract
Despite the efforts for control and eradication of tuberculosis, new cases of the disease are diagnosed daily. The diagnosis of tuberculosis is easily made when the classical features of pulmonary necrotizing granulomatous inflammation are seen. However, extrapulmonary lesions may clinically and radiographically mimic a neoplastic process, and this may lead to misdiagnosis and delay in treatment. We studied 6 patients by aspiration biopsy, all recent immigrants and immunocompetent, who presented with weight loss and fatigue. Of these, 5 patients had a mass. One patient presented with a lytic lesion of bone. In all cases the clinical diagnosis was neoplasia. In all aspirates, the smears showed necrotic debris with neutrophils. No neoplastic cells or granulomas were seen. All cases were signed out descriptively with no specific diagnosis. A search for acid-fast organisms leading to the correct diagnosis of tuberculosis was prompted by clinical investigations that revealed pulmonary lesions, or by repeat aspiration biopsy, which showed granulomatous inflammation. Tuberculosis when present in atypical forms is still a challenging diagnosis. The finding of necrotic debris in a needle biopsy without the clinical signs of an abscess should prompt a search for acid-fast bacilli, since the correct diagnosis will eliminate a needless surgical procedure and will lead to timely and appropriate therapy.

Abstract
Fibroadenoma (FA) is a common benign breast lesion frequently sampled by fine-needle aspiration biopsy (FNAB). Although the cytologic diagnosis is straightforward in most cases, cellular discohesion and atypia in FAs may lead to falsely atypical or positive FNAB diagnoses. Conversely, some adenocarcinomas mimic a fibroadenomatous pattern on FNAB, resulting in a false-negative diagnosis. We reviewed the cytologic and histologic findings in 25 cases with a preoperative FNAB diagnosis of FA, wherein excision was recommended based on atypia. Our aim was to analyze the spectrum of changes causing under- or overdiagnosis in such cases. The smears were assessed for cellularity, cellular discohesion, presence of dissociated intact cells and nucleoli, nuclear pleomorphism, oval bare nuclei, and stromal fragments. The histologic findings were correlated with FNAB features. At excision, 88% of FAs classified as atypical on FNAB were benign (FA with ductal hyperplasia and lactational change, myxoid FA, and other fibroepithelial lesions). Differentiating myxoid FA from colloid carcinoma was difficult due to the abundance of extracellular mucin in which the dissociated epithelial cells were floating. Two (8%) cases were carcinomas on excision; the reasons for underdiagnosis in one case reflected sampling, and in the other, interpretative error. There was one (4%) benign phyllodes tumor which lacked stromal fragments and single stromal cells on FNAB smears. The lesion was called atypical, based on the epithelial discohesion on the smears. We conclude that the majority of FAs with atypia on FNAB are benign lesions. Considering the grave consequences of a false-positive cytologic diagnosis, we recommend a conservative approach in interpreting FNAB smears which overall display a fibroadenomatous pattern.

Abstract
Tubular adenocarcinoma is an invasive mammary adenocarcinoma associated with an excellent prognosis and a low incidence of axillary metastases. However, identification of tubular adenocarcinoma by fine-needle aspiration (FNA) biopsy has proven difficult. One hundred five patients with documented "pure" tubular adenocarcinoma were diagnosed at Tisch Hospital from August of 1992 to December of 1998. Twenty-one of these patients had an FNA before excision. We reviewed the smears of these cases and compared them with cases of fibroadenoma and fibrocystic change to identify criteria for diagnosis. Moderately to highly cellular smears with angular cellular clusters with sharp borders and oval cells outlining these clusters, dispersed single cells with minimal atypia, and the absence or paucity of dispersed bare oval nuclei in the background were features that suggest a diagnosis of tubular adenocarcinoma in our study. Attention to these features in combination with appropriate mammographic findings should preclude a false-negative diagnosis in the majority of cases of tubular adenocarcinoma diagnosed by aspiration biopsy. We point to the presence of the peripheral perpendicular cells in the characteristic tubular arrays as an important clue to the diagnosis of tubular adenocarcinoma.

Abstract
Endometrioma in an operative scar is rare. The majority of patients have no prior history of endometriosis, and symptoms may mimic postoperative hernias. Fine-needle aspiration biopsy (FNAB) can be a valuable diagnostic aid in the evaluation of these subcutaneous abdominal masses. We present the cytologic findings in three cases of abdominal wall endometriomas diagnosed by FNAB. The patients ranged from 31 to 51 years of age. None had a history of endometriosis, but all had prior abdominal operations (two abdominal hysterectomies for fibroids and one cesarean section). They presented 6 months to 7 years later with painful subcutaneous abdominal nodules in their scars ranging from 2 to 6 cm. FNAB was performed by a cytopathologist. The smears were cellular and comprised two distinct cell populations. An epithelial component consisted of flat sheets of polygonal cells with round to oval nuclei and scant cytoplasm. The second component consisted of clusters of fusiform stromal cells. Numerous hemosiderin-laden macrophages were noted in the background. Cytokeratin highlighted the epithelial clusters, and vimentin stained the stromal cells. Electron microscopy showed two epithelial cell types: one with cilia and abundant rough endoplasmic reticulum and the other with numerous microvilli and scattered mitochondria indicative of endometrial differentiation. FNAB provided a rapid and accurate preoperative diagnosis in each case.

Abstract
BACKGROUND Spindle cell and mesenchymal lesions of the lung encompass a wide variety of benign and malignant conditions. However, to the authors' knowledge, because of their rarity, few reports concerning their cytologic findings are available in the literature. The current review emphasizes the cytomorphologic features, differential diagnosis, and potential pitfalls associated with these lesions. METHODS Seven hundred seventy-nine percutaneous lung fine-needle aspiration (FNA) specimens were retrieved from the authors' cytopathology files over a period of 5 years. Sixty-one cases (7.8%) in which a spindle cell component was the dominant or key feature were identified. The authors reviewed the cytologic smears, immunocytochemical studies, and corresponding surgical material and clinical information. RESULTS Of these 61 aspirates, 33 (54%) were reactive processes (31 granulomas, 1 organizing pneumonia, and 1 inflammatory pseudotumor). Five cases (0.8%) were benign neoplasms (2 hamartomas, 2 solitary fibrous tumors, and 1 schwannoma). Twenty-three cases (38%) were malignant neoplasms (8 cases were primary tumors [including 5 carcinomas with spindle cell or sarcomatoid features, 1 spindle cell carcinoid tumor, 1 leiomyosarcoma, and 1 synovial sarcoma] and 15 cases were secondary tumors [including 9 melanomas, 2 leiomyosarcomas, 1 malignant fibrous histiocytoma, 1 meningioma, 1 sarcomatoid renal cell carcinoma, and 1 uterine malignant mixed müllerian tumor]). A specific diagnosis was rendered in 52 cases (85%). No false-positive cases were encountered but there was one false-negative case. One patient who was diagnosed with granulomatous inflammation on FNA was found to have nonsmall cell lung carcinoma on subsequent transbronchial biopsy. No malignant cells were identified in the smears on review. The FNA from the organizing pneumonia was interpreted as a solitary fibrous tumor whereas the inflammatory pseudotumor was diagnosed as granulomatous inflammation. The FNA from one pulmonary hamartoma initially was considered to be nondiagnostic. One solitary fibrous tumor and the schwannoma were diagnosed as smooth muscle tumor and spindle cell tumor, not otherwise specified, respectively. Among the malignant tumors, the primary synovial sarcoma and one of the metastatic malignant melanomas initially were interpreted as primitive neuroectodermal tumor/Ewing sarcoma and poorly differentiated carcinoma, respectively. CONCLUSIONS Spindle cell lesions of the lung rarely are encountered on transthoracic lung FNA and are comprised of a wide variety of benign and malignant entities. By correlating clinical and radiologic data, cytologic findings, and ancillary studies, a high diagnostic accuracy rate can be achieved with FNA.

Abstract
Myofibroblastoma of the breast is a rare benign stromal neoplasm, which occurs primarily in men. Classical myofibroblastoma is a circumscribed, nonencapsulated tumor comprised of bipolar fusiform cells arranged randomly, or in fascicles alternating with broad collagenous bands. Additional histologic variants (the cellular, collagenized, infiltrative, and epitheloid types) have been described. Several case reports describe the cytopathologic features of the classical and cellular variants. We report on a 70-yr-old woman, who presented with a circumscribed mass in her left breast. Aspiration biopsy showed paucicellular smears with singly distributed atypical spindle-shaped cells and rare fragments of collagenized stroma, raising suspicion of a phyllodes tumor. Histologic examination revealed spindle-shaped cells distributed in a diffusely collagenized stroma. Some nuclear atypia was present. To the best of our knowledge, this is the first case reporting the cytologic features of the collagenized variant of myofibroblastoma. Although we believe a specific diagnosis of myofibroblastoma can be rendered in a male based on the typical cytologic and clinical findings in the classical type, the variant forms are difficult to classify accurately and require excision for a definitive diagnosis.

Abstract
The popularity of screening mammography has led to increased detection of mammographic lesions that require pathologic diagnosis. Stereotaxic needle biopsy techniques to sample such lesions can be used to either identify those lesions that require excision from those that can be followed, or to confirm a mammographic impression of malignancy prior to excision. Stereotaxic core biopsy (SCBX) and stereotaxic fine needle aspiration (SFNA) have rarely been directly compared. For this review we undertook a uniform re-analysis of the data that was presented in the published studies of SFNA and/or SCBX. The main endpoint was the negative predictive value (NPV) that measures the frequency that a benign diagnosis is truly benign. There was variability in NPV (likely due to sampling methods) and specific aspects of sampling techniques are discussed. The NPV was compared to indicators of selection of lesions to biopsy (frequency of invasive cancer in the study population), mammographic characteristics (masses or microcalcifications), and the reported nondiagnostic rates. The general conclusion is that SFNA and SCBX are equivalent in accuracy, with considerable variability that reflects the types of lesions that are selected for biopsy and the thoroughness of sampling. For SFNA studies, nondiagnostic rates were inversely related to NPV, and therefore have clinical implications. This was not shown for SCBX studies, and probably reflects an inability to correctly identify non-representative tissue biopsies. The main advantage for including cytologic methods with stereotaxic breast biopsy is immediate sample assessment, and this advantage can also be applied to core needle procedures.

Abstract
A multicentre study was undertaken to provide fundamentals for improved standardization and optimized interpretation guidelines of dynamic contrast-enhanced MRI. Only patients scheduled for biopsy of a clinical or imaging abnormality were included. They underwent standardized dynamic MRI on Siemens 1.0 (163 valid lesions > or = 5 mm) or 1.5 T (395 valid lesions > or = 5 mm) using 3D fast low-angle shot (FLASH; 87 s) before and five times after standardized bolus of 0.2 mmol Gd-DTPA/kg. One-Tesla and 1.5 T data were analysed separately using a discriminant analysis. Only histologically correlated lesions entered the statistical evaluation. Histopathology and imaging were correlated in retrospect and in open. The best results were achieved by combining up to five wash-in or wash-out parameters. Different weighting of false-negative vs false-positive calls allowed formulation of a statistically based interpretation scheme yielding optimized rules for the highest possible sensitivity (specificity 30%), for moderate (50%) or high (64-71%) specificity. The sensitivities obtained at the above specificity levels were better at 1.0 T (98, 97, or 96%) than at 1.5 T (96, 93, 86%). Using a widely available standardized MR technique definition of statistically founded interpretation rules is possible. Choice of an optimum interpretation rule may vary with the clinical question. Prospective testing remains necessary. Differences of 1.0 and 1.5 T are not statistically significant but may be due to pulse sequences.

Abstract
BACKGROUND It is thought that implants interfere with breast cancer diagnosis and that cancers in women who have had breast augmentation carry a worse prognosis. METHODS A prospective breast cancer database was reviewed, comparing augmented and nonaugmented patients for details of histology, palpability, tumor size, nodal status, mammographic status, receptor status, nuclear grade, stage, and outcome. RESULTS Ninety-nine cancers in augmented women and 2857 cancers in nonaugmented women were identified. Among these women, mammography was normal in 43% of those who had had augmentation and in 5% of those who had not. Augmented women were more likely to have palpable cancers (83% vs. 59%) and nodal involvement (48% vs. 36%), and less likely to have ductal carcinoma in situ (DCIS) (18% vs. 28%). When comparing only women younger than 50, the differences in invasiveness and nodal status lost significance. Cancers diagnosed in the 1990s were more likely to be nonpalpable and noninvasive than those diagnosed in the 1980s. This trend was more pronounced in the augmented population. CONCLUSIONS Augmented patients were more likely to have palpable cancers, although the overall stage and outcome were similar to those of nonaugmented women. Although there have been significant improvements in our ability to diagnose early breast cancer over the past two decades, mammography continues to be suboptimal in augmented women.

Abstract
OBJECTIVE To investigate the applicability of the Ultrafast Papanicolaou stain to the cytology of fluids and to compare it with other methods. STUDY DESIGN Over a 30-month period, 528 unfixed fluids (462 serous effusions, 48 pelvic washings, 16 cyst fluids and 2 bile duct drain fluids) were mixed thoroughly and centrifuged. Two Swedish-style air-dried smears were made and stained with Diff-Quik (Mercedes Medical, Inc., Sarasota, Florida, U.S.A.) and Ultrafast Papanicolaou stain (Richard Allan Scientific, Kalamazoo, Michigan, U.S.A.), and the remaining sediment was fixed in CytoRich Red (TriPath Imaging, Inc., Burlington, North Carolina, U.S.A.), centrifuged onto a 17.5-mm circle with a Hettich cytocentrifuge and stained by the Papanicolaou method. RESULTS For the 115 malignant fluids, Ultrafast Papanicolaou stain was the preferred method in the 94 non-hematopoietic malignant fluids, Diff-Quik was the preferred method in the 9 hematopoietic malignancies, and CytoRich Red was the preferred preparation in 8 bloody effusions containing rare cancer cells and 4 malignant pelvic washings. The diagnostic turnaround time of smears stained by Ultrafast Papanicolaou stain was < 15 minutes, fast enough for intraoperative consultations. CONCLUSION It seems that Ultrafast Papanicolaou stain improves the resolution of cytoplasmic and nuclear details of nonhematopoietic cells in body fluids. However, to detect cancer in all types of fluids, Diff-Quik and CytoRich preparations are also required. We now examine three slides per fluid sample, one slide by each of the three techniques.

Abstract
Angiosarcoma is the most common malignant neoplasm of the heart. However, to the authors' knowledge, no cytogenetic study of cardiac angiosarcoma has been reported. In the current study, an angiosarcoma from the right atrium of a 29-year-old man was investigated. Examination of tissue sections indicated that the tumor was a high grade epithelioid angiosarcoma of the heart. Cytogenetic analysis of tumor cells revealed a hyperdiploid clonal population with chromosomal numerical changes and one structural rearrangement, which was defined as: 55, XY, +der(1;17) (q10:q10), +2, +7, +8, +8, +19, +20, +21, +22. Multicolor fluorescent in situ hybridization on paraffin-embedded tissue sections illustrated polysomy of chromosome 8 in tumor cells. In addition, immunohistochemical analysis showed high expression of mutated p53 gene products in tumor cell nuclei. These findings demonstrate the involvement of chromosomal anomalies and gene mutation in cardiac angiosarcoma and suggest they play a role in neoplasia of the heart.

Abstract
BACKGROUND Although stereotaxic fine-needle aspiration biopsy or core biopsy (14-gauge) have proven to be accurate techniques for the evaluation of mammographically detected microcalcification, the development of the Mammotome Biopsy System (Biopsys Medical, Inc., Irvine, CA) has led many medical centers to use this vacuum-assisted device for the sampling of microcalcification. METHODS One hundred forty-two women underwent 160 stereotaxic Mammotome core biopsies of mammographic calcification over a 1-year period. The stereotaxic procedure was performed by radiologists using the Mammotome Biopsy System. Microcalcification was evident on specimen radiographs and microscopic slides in 99% of the cases. Excisional biopsy was recommended for diagnoses of atypia or carcinoma. Patients with benign diagnoses underwent mammographic followup. RESULTS One hundred thirty-two benign, 12 atypical, and 15 adenocarcinoma diagnoses (comprising 1 lobular adenocarcinoma in situ [LCIS], 1 invasive ductal adenocarcinoma [IDC], and 13 intraductal adenocarcinomas [DCIS]: 10 comedo, 1 cribriform, 2 mixed cribriform and micropapillary) were rendered. Surgical excision in eight patients with atypia on Mammotome biopsy (two refused surgery, two were lost to followup) showed ductal hyperplasia in three, atypical ductal hyperplasia (ADH) in three and DCIS (low grade, solid) in two patients. Surgical excisions in 14 patients diagnosed with carcinoma (1 patient lost to followup) showed ADH in 3, ADH and LCIS in 1, residual DCIS in 8, IDC in 1, and microinvasive carcinoma in 1 patient. CONCLUSIONS A diagnosis of atypia on Mammotome biopsy warranted excision of the atypical area, yet the underestimation rate for the presence of carcinoma remained low. The likelihood of an invasive component at excision was low for microcalcification diagnosed as DCIS on Mammotome biopsy. Mammotome biopsy proved to be an accurate technique for the sampling and diagnosis of mammary microcalcification.

Abstract
The information contained in pathology reports of radical prostatectomy specimens is critically important to treating physicians for selecting adjuvant therapy, evaluating therapy, estimating prognosis, and analyzing outcomes. This information is also of importance to patients and their families. In recent years, the Cancer Committee of the College of American Pathologists and the Association of Directors of Anatomic and Surgical Pathology developed suggested protocols for reporting the findings on radical prostatectomy specimens. The objectives of this study were to assess radical prostatectomy-specimen reports by using quality indicators derived from existing suggested protocols and to thereby assist pathologists in improving the quality of their reports on such specimens. A retrospective chart review of 554 cases for the second 6-month period of 1996 focused on 10 quality indicators: submission of a frozen section; location of the adenocarcinoma; proportion of the specimen involved by adenocarcinoma; perineural involvement; vascular involvement; seminal vesicle involvement; periprostatic fat status; number of nodes submitted; status of nodes; and prostate intraepithelial neoplasia (PIN). The findings of this study were shared with the pathology departments in all hospitals in New York State. In addition, the 113 hospitals from which the 554 cases were drawn were given their institution-specific data. Teleconferences were held with the 37 hospitals that accounted for 72.4% of all cases. These conferences included directors of pathology and laboratories and focused on the aggregate statewide findings. The presence of quality indicators in reports varied from a mean of 14.8% (periprostatic fat) to a mean of 85.9% (seminal vesicle involvement). For all hospitals, 4 indicators (proportion of the specimen involved by adenocarcinoma, vascular involvement, periprostatic fat status, and PIN) were included in fewer than 50% of cases. These 4 quality indicators and an additional 3 others (submission of a frozen section, perineural involvement, and the number of nodes submitted) were included in fewer than 70% of cases. Only 3 indicators (location of the adenocarcinoma, seminal vesicle involvement, and the status of nodes) were found in more than 70% of cases. Although the mean level of quality indicator inclusion ranged from 14.8% to 85.9% for all cases examined, the absolute range for any individual indicator was 0% to 100%. Thus, some hospitals included a given indicator 100% of the time; others never included it. This pattern held true for all 10 indicators. High-volume hospitals (10 or more cases) performed significantly better than low-volume hospitals (1-4 cases) on 5 indicators (P < .05), and better, but not significantly so, for an additional 2 indicators. Overall, the mean inclusion levels for all 10 indicators were 10% higher for high-volume hospitals compared with low-volume and medium-volume hospitals (5-9 cases). This study demonstrated wide variations in the inclusion of quality indicators by pathologists in their radical prostatectomy-pathology reports. Whereas some hospitals always include given indicators, others never mentioned them. These marked disparities point to the need for standardized reporting for radical prostatectomy specimens.

Abstract
OBJECTIVE To assess the risk for melanoma associated with moles and pigmentary characteristics. METHODS Representative melanoma cases (773) among non-Hispanic white residents under age 65 occurring between 1 June 1978 and I December 1983 in Los Angeles County were compared to controls (752) matched to cases by age, sex, race and neighborhood of residence. Factors considered include hair, eye, and skin color; numbers of freckles and moles; and propensity to burn and tan obtained during an in-person interview. RESULTS Five hundred and fifty-one cases were classified as superficial spreading melanoma (SSM) and 110 as nodular melanoma (NM). For SSM, the important risk determinants were hair and skin color, freckling, and mole prevalence. Light skin and more freckles were found to be more highly associated with SSM for younger compared to older subjects, whereas the associations between SSM and both hair color and moles remained independent of age. NM showed patterns of risk similar to SSM with the exception of skin color. NM showed no evidence of increasing risk with lighter skin, as compared to the strong association seen for SSM. CONCLUSION Hair and skin color, freckling and, especially, numbers and size of moles are important determinants of melanoma risk.

Abstract
BACKGROUND AND OBJECTIVES The ability to achieve clean margins with breast conserving therapy varies greatly even when the diagnosis of carcinoma is known beforehand. Although several reports reveal that the incidence of positive margins decreases after stereotaxic core biopsy of nonpalpable lesions and fine-needle aspiration biopsy of palpable lesions, the data on the results following mammotome biopsy (mmbx) is scanty. METHODS Two hundred and ninety-eight biopsy specimens for mammographically indeterminate microcalcification from 1/97 through 3/30/98 were reviewed. Biopsies were performed using the biopsys method utilizing an 11-gauge multidirectional, vacuum-directed device. RESULTS Ten percent (n = 31) of the mammotome biopsies were atypical and 9% (n = 27) were malignant. These 58 cases (19%) were recommended for surgical excision. The incidence of positive margins in this subset was determined. Of patients who underwent lumpectomy as their initial surgical procedure 69% had negative surgical margins. Seventy-seven percent of patients with carcinoma diagnosed by mammotome biopsy had definitive initial surgery with a single surgical procedure. CONCLUSIONS Mmbx facilitates fewer surgical procedures to achieve negative margins, and thus provides a better cosmetic result.

Abstract
BACKGROUND The presence of lymph node metastases in patients with malignant melanoma implies a significant decrease in survival. The authors investigated the efficacy of fine-needle aspiration biopsy (FNAB) in the diagnosis of metastatic malignant melanoma in 115 patients with melanoma and clinically suspicious regional lymph nodes. METHODS One hundred thirty-three FNABs were performed by cytopathologists after referral from surgeons or oncologists using a 25-gauge or 27-gauge needle. RESULTS The cytologic diagnosis was negative in 35, atypical in 1, suspicious in 2, and positive for malignant melanoma in 95. Regional lymph node dissections were performed in 78 patients. Of these, 70 positive FNABs were confirmed with no false-positive results. The atypical FNAB was proven positive for malignant melanoma at surgery. Of the two suspicious FNABs, one was confirmed as positive and one showed dermatopathic lymphadenopathy. Of the 35 negative FNAB specimens, 5 patients underwent surgery; 3 FNABs were found to be negative and 2 FNABS were falsely negative. Twenty patients with negative aspirates were followed clinically for 22-45 months (mean, 32 months); 19 patients had no evidence of disease and 1 patient died of disseminated melanoma. CONCLUSIONS FNAB of palpable lymphadenopathy in patients with malignant melanoma can provide a rapid and accurate assessment of lymph node status and expedite the therapeutic management of these patients.

Abstract
BACKGROUND Fine-needle aspiration (FNA) biopsy of palpable breast masses along with clinical and radiologic findings can provide rapid distinction between benign and malignant lesions. A preoperative determination of invasive or in situ carcinoma assists in the planning of definitive treatment. Previous studies have concentrated on whether cytologic features adequately distinguish invasion, but to the authors' knowledge the predictive value of clinicopathologic correlation has not been investigated. The authors attempted to determine whether a malignant cytologic diagnosis for a palpable breast mass is sufficient for its definitive surgical management as an invasive neoplasm. METHODS The authors reviewed 351 FNAs from palpable breast lesions with a cytologic diagnosis of "adenocarcinoma." The presence of invasive disease was determined by histologic demonstration of invasive carcinoma in the corresponding surgical specimen or by identifying metastatic carcinoma in the absence of another primary source. RESULTS Three hundred forty-three (97.7%) palpable tumors diagnosed as adenocarcinoma by FNA proved to be invasive adenocarcinoma. The remaining eight tumors contained high grade ductal carcinoma in situ, and two of these contained foci suggestive of microinvasion. CONCLUSIONS A palpable breast mass with an FNA diagnosis of adenocarcinoma usually represents invasive carcinoma. A definitive treatment plan therefore can be planned based on these clinical and FNA findings.

Abstract
Metastases of tumors of extramammary origin to the breast are extremely uncommon. We report the case of an 81-year-old man with a history of prostatic adenocarcinoma treated with adjuvant estrogen therapy, who presented with bilateral palpable mammary masses. Mammographic study showed irregular solid nodules. Fine needle aspiration (FNA) biopsy was performed. The aspiration smears showed single cells with high nuclear/cytoplasmic ratios, prominent nucleoli, and rare acinar formations. Immunocytochemical studies using antibodies against prostate-specific antigen and prostate-specific acid phosphatase confirmed the diagnosis of metastatic prostatic adenocarcinoma, allowing appropriate treatment.

Abstract
OBJECTIVE To search for low-power, or "architectural," clues to the diagnosis of the follicular variant of papillary thyroid adenocarcinoma (FVP) in Diff-Quik-stained aspiration biopsy smears in order to aid in the rapid diagnosis of FVP, especially as a complement to frozen sections. STUDY DESIGN The smears of 23 cases, each with tissue-proven FVP, were compared to those of 23 cases of classic papillary thyroid adenocarcinoma (PTA), 23 cases of tissue-proven follicular neoplasms (FN) (i.e., adenoma or well-differentiated adenocarcinoma) and 23 samples of colloid nodules (CN). The low-power (10x) features of the four groups were studied and compared. RESULTS Our study showed that FVP exhibited monolayered cellular sheets with branched, irregular contours, which can be distinguished from the uniform microfollicles with smooth contours formed in FN and the large, round or oval monolayered sheets of follicular cells found in CN. FVP shared all of the features of classic PTA except for the larger, complex sheets of epithelial cells and psammoma bodies found in the latter. CONCLUSION The branched sheets of epithelial cells evident during low-power examination of Diff-Quick-stained smears of thyroid aspirates are a ready first clue to the rapid diagnosis of FVP. The diagnosis can be confirmed by subsequent careful evaluation of nuclei in Papanicolaou-stained smears and sections of tissue.

Abstract
OBJECTIVE To investigate whether the assessment of apoptotic index (AI) from fine needle aspiration (FNA) smears of non-Hodgkin's lymphomas (NHL) is reliable and has potential utility as a criterion to predict histologic grade. STUDY DESIGN AI was independently determined by four cytopathologists as a percentage from routine FNA smears in 96 NHLs and 15 lymphoid hyperplasias. Working formulation (WF) grades from corresponding surgical biopsies were modified to include mantle zone-derived NHLs as intermediate grade and to make diffuse large cell NHL a separate category called "high" grade, whereas WF high grade NHLs were called "very high" grade. Histologic grades were also derived from the Revised European American Lymphoma (REAL) classification. AI was compared with histologic grade using the unpaired, two-tailed Student t test. These data were used to determine potential thresholds for AI that separate lower from higher grade NHLs. RESULTS Measurements of AI strongly correlated between cytopathologists (median r = .93). Low and intermediate grade NHLs had indistinguishable AIs, whereas higher grade NHLs had significantly higher AIs. Appropriate potential AI thresholds between low or intermediate grade and higher grade NHLs were in the range of 1.5-2.5% (modified WF) and 1-2% (REAL). CONCLUSION There is excellent interobserver reliability in the measurement of AI from FNAs of NHLs. Higher AIs distinguish higher from lower grade NHLs. Diffuse large cell NHLs had AIs that were similar to WF high grade NHLs.

Abstract
We report a case of desmoplastic malignant melanoma metastatic to the parotid gland initially evaluated by fine-needle aspiration. The cytologic findings consisted of scattered spindle cells in a background of heterogeneous lymphoid cells. The spindle cells were scant and displayed mild cytologic atypia. In addition, rare stromal fragments were also present. Cytoplasmic pigment and intranuclear cytoplasmic inclusions were not seen. The initial impression was that of a reactive lymph node with fibrosis. In retrospect, rare spindle cells displayed moderate atypia. In addition, the stromal fragments were cellular and contained spindle cells with mild atypia. These cytologic findings along with a known history of malignant melanoma should provide clues to the correct diagnosis of desmoplastic malignant melanoma. Diagn. Cytopathol. 2000;22:97-100.

Abstract
Metastases or secondary deposits account for 16% of the malignant neoplasms involving the major salivary glands. A correct diagnosis of a secondary neoplasm is important to avoid unnecessary radical surgery and to guide further therapy. Fine-needle aspiration biopsy (FNAB) is an excellent noninvasive diagnostic tool for evaluating salivary gland lesions. We reviewed 36 secondary malignant salivary gland neoplasms evaluated by FNAB. Ancillary studies were performed in selected cases. Follow-up included clinical correlation and review of histologic material. For 4 adenocarcinomas, 4 squamous cell carcinomas, 1 undifferentiated carcinoma, 1 cutaneous basal cell carcinoma, 10 cutaneous melanomas including 1 desmoplastic variant, 3 osteosarcomas, 11 non-Hodgkin lymphomas, and 2 multiple myelomas, there was 1 false-negative FNAB result. The desmoplastic melanoma was interpreted as reactive lymphoid hyperplasia. A malignant diagnosis was given in all remaining cases except the secondary basal cell carcinoma, which was diagnosed as a neoplasm with basal cell features. FNAB is a reliable tool to differentiate hematologic malignant neoplasms and melanomas from other salivary gland neoplasms. A complete knowledge of the clinical history, review of previous pathologic materials, and, in some instances, the use of ancillary studies are crucial for recognizing solid malignant neoplasms secondarily involving the salivary glands.

Abstract
In the hypertensive population, primary aldosteronism has been reported to have a prevalence of 0.1% to 2%, with the main causes being aldosterone-producing adenomas and bilateral hyperplasia. However, there is a third rare entity, called unilateral adrenal hyperplasia, that contributes to primary aldosteronism. Unilateral hyperplasia and primary aldosteronism are the subjects of this case review.
