Abstract
Patients with advanced colorectal cancer (CRC) with distant metastases have a poor prognosis. We evaluated the clinicopathological relevance of GRP94 expression in these cases. The immunohistochemical expression of GRP94 was studied in 189 CRC patients with synchronous (SM; n = 123) and metachronous metastases (MM; n = 66), using tissue microarray; the association between GRP94 expression, outcome, and tumor-infiltrating lymphocytes (TILs) was also evaluated. GRP94 was expressed in 64.6% (122/189) patients with CRC; GRP94 positivity was found in 67.5% and 59.1% patients with SM and MM, respectively. In the SM group, high GRP94 expression was more common in patients with a higher density of CD4+ TILs (p = 0.002), unlike in the MM group. Survival analysis showed that patients with GRP94 positivity had significantly favorable survival (p = 0.030); after multivariate analysis, GRP94 only served as an independent prognostic factor (p = 0.034; hazard ratio, 0.581; 95% confidence interval, 0.351-0.961) in the SM group. GRP94 expression was detected in 49.4% of metastatic sites and showed significant heterogeneity between primary and metastatic lesions (p = 0.012). GRP94 is widely expressed in CRC with distant metastases; its expression was associated with favorable prognosis in the SM group, unlike in the MM group.

Abstract
CONTEXT Women with congenital adrenal hyperplasia (CAH) may present with androgen excess that is difficult to control with conventional suppressive doses of glucocorticoids. Clinical management is challenging, and the woman is at great risk of developing steroid-induced complications. PATIENTS AND METHODS A 32-year-old woman with salt-wasting CAH due to 21-hydroxylase deficiency underwent right-sided adrenalectomy because of a large myelolipoma. Over the years, androgens became increasingly difficult to suppress on prednisolone 5 + 0 + 2.5 mg daily, and at age 39 years the left adrenal with an enlarging myelolipoma was removed. A month later serum testosterone levels had increased from 4.1 preoperatively to 18.3 nmol/L (reference 0.2-1.8 nmol/L), and adrenocorticotropin levels from 32 to 283 pmol/L (reference < 14 pmol/L). No adrenal parenchyma was visualized on computed tomography (CT). In the further search for the source of the markedly elevated testosterone, positron emission tomography (PET) was performed with 2 different tracers, 18fluorodeoxyglucose (18FDG) reflecting glucose metabolism and 11C-metomidate, an inhibitor of 11-β-hydroxylase targeting adrenocortical tissue. RESULTS 18FDG-PET/CT with cosyntropin stimulation showed ovarian/paraovarian hypermetabolism, suggestive of adrenal rest tumors. Further characterization with 11C-metomidate PET/CT showed uptakes localized to the ovaries/adnexa, behind the spleen, and between the right crus diaphragmaticus and inferior vena cava. CONCLUSION Adrenal rest tumors can give rise to high androgen levels in spite of suppressive supraphysiological glucocorticoid doses. This case illustrates, for the first time, the value of 11C-metomidate PET as a sensitive method in documenting adrenal rest tumors, currently considered rare in women with CAH.

Abstract
BACKGROUND The survival of patients with advanced hepatocellular carcinoma (HCC) is highly variable due to heterogeneous tumoral characteristics. We proposed and validated an albumin-bilirubin (ALBI)-based model for HCC beyond Milan criteria, the ALBI-HOME, for these patients. METHODS A total of 2186 patients were enrolled and randomly assigned to the derivation cohort (n = 1093) and validation cohort (n = 1093). Multivariate Cox proportional hazards model was used to determine significant prognostic factors in the derivation cohort. The performance of ALBI-HOME was evaluated in the validation cohort. RESULTS In the Cox model, six factors were identified as independent predictors of poor survival: ALBI grade 2 [hazard ratio (HR) 1.848, 95% confidence incidence (CI) 1.556-2.195, p < 0.001], ALBI grade 3 (HR 3.266, 95% CI 2.531-4.215, p < 0.001), serum AFP ≥ 100 ng/ml (HR 1.482, 95% CI 1.279-1.717, p < 0.001), total tumor volume ≥ 250 cm3 (HR 1.503, 95% CI 1.294-1.746, p < 0.001), ascites (HR 1.400, 95% CI 1.187-1.561, p < 0.001), performance status 0-1 (HR 1.756, 95% CI 1.485-2.076 p < 0.001), and vascular invasion or metastasis (HR 2.110, 95% CI 1.809-2.0, p < 0.001). The ALBI-HOME is based on these six parameters, and the score ranges from 0 to 7. This model was associated with the best prognostic ability among different HCC staging systems to predict survival in patients beyond Milan criteria; its ability remained consistently stable in different treatment subgroups and viral etiologies. CONCLUSIONS The proposed ALBI-HOME is a simple and feasible predictive model for HCC beyond Milan criteria. It demonstrates superior prognostic performance among the currently used staging systems and may help identify at-risk patients to undergo more aggressive treatments.

Abstract
BACKGROUND Pituitary adenoma and meningioma are the most common benign tumors in the central nervous system. Pituitary adenoma associated with meningioma (PAM) is a rare disease and the clinical features and mechanisms of PAM are unclear. METHODS We summarized the clinical data of 57 PAM patients and compared with sporadic pituitary adenoma (SPA) and sporadic meningioma (SM). 5 pituitary adenomas of PAM and 5 SPAs were performed ceRNA microarray. qRT-PCR, Western Blot, siMEN1 and rapamycin inhibition experiment were validated for ceRNA microarray. RESULTS Clinical variable analyses revealed that significant correlations between PAM and female sex as well as older age when compared with SPA and significant correlations between PAM and transitional meningioma as well as older age when compared with SM. Additionally, the characteristics of PAM were significantly different for MEN1 patients. Functional experiments showed lower expression of MEN1 can upregulate mTOR signaling, in accordance with the result of ceRNA microarray. Rapamycin treatment promotes apoptosis in primary pituitary adenoma and meningioma cells of PAM. CONCLUSIONS MEN1 plays an important role in PAM by upregulating mTOR signaling pathway. Rapamycin represents a potential therapeutic strategy for PAM in the future.

Abstract
We report a case of myeloid sarcoma with multifocal skeletal involvement, including the greater wing of the sphenoid bone. A 23-month-old boy presented with left-sided proptosis and fevers, and was found to have an infiltrative mass involving the left sphenoid bone on orbital imaging. Full body imaging further demonstrated multiple bony lesions in the pelvis, thoracic and lumbar vertebrae, bilateral femura, and left humerus, and biopsies of the humerus were consistent with myeloid sarcoma. The patient was started on a standard chemotherapy regimen and is responding well. Myeloid sarcoma presenting with proptosis due to sphenoid bone involvement with simultaneous multifocal skeletal involvement is very uncommon and highlights the importance of biopsy for establishing a definitive diagnosis.

Abstract
Thyrotropin (TSH)-secreting pituitary tumors are the rarest functioning pituitary tumors. Nonetheless, they are not infrequently plurihormonal, as they may express/secrete hormones made by other pituitary cells derived from the Pit-1 lineage such as growth hormone (GH), prolactin (PRL), and α-subunit (αSU). However, adrenocorticotropin (ACTH) or gonadotropin secretion by such a tumor is exceptional. Although double pituitary tumors are rare, they often combine ACTH and GH secretion. A 41-year-old presented almost 2 years after delivering her 10th child; she had thyrotoxicosis (goiter and palpitations) masquerading as autoimmune postpartum thyroiditis. She was still breastfeeding and amenorrheic. She proved to have TSH, GH, PRL, and ACTH hypersecretion. Imaging revealed an invasive pituitary macrotumor. She had stigmata neither of Cushing's disease nor of acromegaly. Prior to surgery, hormonal control was achieved for close to 1 year by combined octreotide and cabergoline treatment with significant shrinking of the tumor. Following surgery, pathology revealed a collision tumor; the dominant lesion was positive for GH, βTSH, βFSH, and αSU and expressed both Pit-1 and SF-1.The smaller lesion was a corticotroph tumor. We report an unusual plurihormonal tumor co-expressing Pit-1 and SF-1 along with hormones made by cells of both lineages. Its simultaneous occurrence adjacent to a corticotroph tumor raises questions regarding the pathogenesis of these tumors. We propose the possibility of a stem cell tumor with multiple lineage differentiation. We hypothesize that pregnancy might have played a permissive role in tumorigenesis.

Abstract
Synchronous endometrial and ovarian carcinomas) represent 5% to 10% of endometrial or ovarian carcinomas. We assessed genetic alterations (in PTEN, CTNNB1, POLE, etc) and evaluated correlations with patient outcomes to determine the utility of clonality analyses for differentiating between metastases and concurrent primary tumors and for determining whether genetic alterations in synchronous tumors are predictive of biological behavior. Genomic DNA was isolated from formalin-fixed, paraffin-embedded tissues and frozen tissues from patients with synchronous endometrial and ovarian carcinomas. Samples were obtained from the Department of Obstetrics and Gynecology at the Shimane University School of Medicine between 2003 and 2017. Sanger sequencing was used to analyze the mutational status of the coding exons in TP53, PTEN, POLE, PIK3CA, KRAS, and CTNNB1 using previously published primers. All patients lived, and 3 had disease recurrence. The frequencies of somatic mutations in TP53, PTEN, CTNNB1, KRAS, and POLE were 3 (37.5%), 2 (25.0%), 3 (37.5%), 0 (0.0%), and 5 (62.5%) of 8 cases in ovarian tumors and 3 (37.5%), 2 (25.0%), 3 (37.5%), 1 (12.5%), and 5 (62.5%) of 8 cases in endometrial tumors, respectively. The frequencies of POLE and CTNNB1 mutations were higher than those in previous reports. A clonal relationship was determined by genomic analyses in 3 of 6 cases that were initially diagnosed as primary independent tumors. We confirmed that these 3 cases were indicated metastatic tumors because the lesion of mutation was the same. This information, provided by the sequencing-based strategy, could be useful for hypothesizing a patient's prognosis and deciding on treatment.

Abstract
Primary hyperparathyroidism is the most common hormonal manifestation associated with multiple endocrine neoplasia 1 (MEN1). It is generally caused by parathyroid hyperplasia, and parathyroid carcinoma is rare. Here, we report a case of MEN1 with parathyroid carcinoma in two parathyroid glands causing primary hyperparathyroidism. A 40-year-old man with primary hyperparathyroidism due to MEN1 underwent a total parathyroidectomy. His corrected calcium and intact PTH (i-PTH) serum levels were 10.8 mg/dL and 203 pg/mL, respectively. Although three glands were successfully removed, the left upper parathyroid gland could not be detected. Since the right lower parathyroid lesion had invaded into the thyroid, right lobectomy was performed. A portion of the left lower parathyroid tissue was transplanted into his forearm. The histological findings of the left lower and the right upper parathyroid glands were consistent with hyperplasia while that of the right lower parathyroid gland was parathyroid carcinoma. Since the post-surgical i-PTH levels remained high, the intrathyroidal lesion of the left lobe, which was initally diagnosed as an adenomatous nodule, was suspected to contain parathyroid tumor. A fine needle aspiration of the tumor revealed a high concentration of i-PTH. One week after the first surgery, a left thyroid lobectomy was performed. The pathological diagnosis of the tumor was parathyroid carcinoma. After the surgery, calcium and i-PTH levels were normal. Although it is rare, parathyroid carcinoma should be considered as a cause of hyperparathyroidism in MEN1 patients. Since it is difficult to diagnose parathyroid carcinoma before surgery, intraoperative findings are important for the appropriate treatment.

Abstract
CONTEXT Whether primary aldosteronism (PA) is the consequence of a monoclonal or multiclonal process is unclear. CASE DESCRIPTION A 48-year-old man with severe bilateral PA refractory to medical therapy underwent unilateral adrenalectomy of the dominant adrenal. Although computed tomography showed three left-sided cortical nodules, postsurgical histopathology and genetic analysis revealed five different adrenocortical adenomas. Two zona fasciculata (ZF)-like aldosterone-producing adenomas (APAs) each harbored distinct known somatic KCNJ5 mutations (L168R and T158A). A zona glomerulosa-like APA harbored a known CACNA1D G403R somatic mutation, whereas a zona reticularis-like adenoma, which was grossly black in pigmentation with histologic characteristics more associated with cortisol-producing adenomas, expressed CYP11B2, CYP17, and DHEA-ST by immunohistochemistry (IHC) and harbored no known somatic mutations. The fifth adenoma was ZF-type, negative for CYP11B2 and CYP17 IHC, and harbored no known somatic mutations. CONCLUSIONS This case highlights complex intertumor heterogeneity in histology, steroidogenesis, and somatic mutations in multiple adrenocortical adenomas arising in a single patient with PA. These findings suggest that the syndrome of PA can involve heterogeneous and multiclonal functional adrenal adenomas.

Abstract
Mantle cell lymphoma (MCL) has tropism for the gastrointestinal tract (GIT) identifiable as multiple polyps and mass lesions throughout the GIT. We describe 2 novel manifestations of MCL. A 60-year-old woman with known chronic lymphocytic leukemia (CLL) had an exophytic mass of the appendiceal orifice. Multiple polypoid masses of the distal ileum were identified in the right hemicolectomy specimen (multiple lymphomatous polyposis). Ancillary studies confirmed the coexistence of the 2 independent lymphoproliferative disorders. A 69-year-old man had recurrent urinary tract infections and pneumatouria caused by a colovesicular fistula complicating diverticulosis coli. Segmental resections of the sigmoid and ileocecum confirmed diverticulosis of the left and right colon. Histology identified infiltrates of MCL confined to the penetrating aspects of colonic diverticula. MCL has not been documented to coexist with CLL. An invaginating morphology of lymphoma, multiple lymphomatous diverticulosis is also a novel presentation. These 2 scenarios expand MCL's known manifestations within the GIT.

Abstract
BACKGROUND Studies have suggested that microRNAs (miR) may be useful prognostic markers and are associated with aggressive clinicopathologic features in papillary thyroid cancer (PTC). This systematic review examined associations between miRs and aggressive clinicopathologic features in PTC. METHODS A literature search was performed within the PubMed, Embase, Cochrane, Web of Science, and Scopus databases for papers published prior to November 24, 2014. The search was performed by combining the concepts "thyroid tumor" with "microRNA" and by using "and" as the Boolean operator. Upon retrieval of candidate studies, full-text publications were reviewed in their entirety and selected if they examined the prognostic significance between miR expression and established aggressive clinicopathologic features of PTC. RESULTS Fifteen studies from 13 unique groups that included 807 patients were reviewed. Most of the studies were retrospective, and none included patients who had undergone routine central lymph node dissection. Expression levels of miRs-21, -34b, -130b, -135b, -146b, -151, -181b, -199b-5p, -221, -222, -451, -623, -1271, -2861, and let-7e showed significant association with at least one aggressive feature, such as large tumor size, extrathyroidal extension, multifocality, lymphovascular invasion, lymph node metastases, distant metastasis, advanced American Joint Cancer Committee stage, and presence of the BRAF(V600E) mutation. Herein we summarize the literature with regard to these associations. CONCLUSION Further studies are needed to investigate whether miRs are independent predictors of aggressive clinicopathologic features before it can be recommended that miR expression levels should be incorporated into the management algorithm for patients with PTC. A well-designed prospective study is needed to assess these potential associations.

Abstract
Mutations of the multiple endocrine neoplasia type 1 (MEN1) gene lead to loss of function of its protein product menin. In keeping with its tumor suppressor function in endocrine tissues, the majority of the MEN1-related neuroendocrine tumors (NETs) show loss of heterozygosity (LOH) on chromosome 11q13. In sporadic NETs, MEN1 mutations and LOH are also reported, indicating common pathways in tumor development. Prevalence of thymic NETs (thNETs) and pulmonary carcinoids in MEN1 patients is 2-8%. Pulmonary carcinoids may be underreported and research on natural history is limited, but disease-related mortality is low. thNETs have a high mortality rate. Duodenopancreatic NETs (dpNETs) are multiple, almost universally found at pathology, and associated with precursor lesions. Gastrinomas are usually located in the duodenal submucosa while other dpNETs are predominantly pancreatic. dpNETs are an important determinant of MEN1-related survival, with an estimated 10-year survival of 75%. Survival differs between subtypes and apart from tumor size there are no known prognostic factors. Natural history of nonfunctioning pancreatic NETs needs to be redefined because of increased detection of small tumors. MEN1-related gastrinomas seem to behave similar to their sporadic counterparts, while insulinomas seem to be more aggressive. Investigations into the molecular functions of menin have led to new insights into MEN1-related tumorigenesis. Menin is involved in gene transcription, both as an activator and repressor. It is part of chromatin-modifying protein complexes, indicating involvement of epigenetic pathways in MEN1-related NET development. Future basic and translational research aimed at NETs in large unbiased cohorts will clarify the role of menin in NET tumorigenesis and might lead to new therapeutic options.

Abstract
Epigenetics are thought to play a major role in the carcinogenesis of multiple sporadic colorectal cancers (CRC). Previous studies have suggested concordant DNA hypermethylation between tumor pairs. However, only a few methylation markers have been analyzed. This study was aimed at describing the epigenetic signature of multiple CRC using a genome-scale DNA methylation profiling. We analyzed 12 patients with synchronous CRC and 29 age-, sex-, and tumor location-paired patients with solitary tumors from the EPICOLON II cohort. DNA methylation profiling was performed using the Illumina Infinium HM27 DNA methylation assay. The most significant results were validated by Methylight. Tumors samples were also analyzed for the CpG Island Methylator Phenotype (CIMP); KRAS and BRAF mutations and mismatch repair deficiency status. Functional annotation clustering was performed. We identified 102 CpG sites that showed significant DNA hypermethylation in multiple tumors with respect to the solitary counterparts (difference in β value ≥0.1). Methylight assays validated the results for 4 selected genes (p = 0.0002). Eight out of 12(66.6%) multiple tumors were classified as CIMP-high, as compared to 5 out of 29(17.2%) solitary tumors (p = 0.004). Interestingly, 76 out of the 102 (74.5%) hypermethylated CpG sites found in multiple tumors were also seen in CIMP-high tumors. Functional analysis of hypermethylated genes found in multiple tumors showed enrichment of genes involved in different tumorigenic functions. In conclusion, multiple CRC are associated with a distinct methylation phenotype, with a close association between tumor multiplicity and CIMP-high. Our results may be important to unravel the underlying mechanism of tumor multiplicity.

Abstract
Myeloid sarcoma (MS) is an extramedullary myeloid tumor that sometimes presents with antedating systemic leukemia, leading physicians to the misdiagnosis of lymphoma. CD25 is expressed in 13% of patients with acute myeloid leukemia (AML), and its expression is associated with FLT3-ITD mutations, an elevated serum soluble interleukin 2 receptor (sIL-2R) level and a lower survival rate. However, there are no reports concerning the relationship between MS and the CD25 expression. We herein report a case of AML accompanied by thoracic epidural MS with a high CD25 expression, the FLT3-ITD mutation and an extremely elevated serum sIL-2R level in a 59-year-old man who presented with paraplegia.

Abstract
Somatic mutations of the catalytic subunit of the cyclic AMP-dependent protein kinase (PRKACA) gene have recently been identified in about 35% of cortisol-producing adenomas (CPAs), with the affected patients showing overt Cushing's syndrome. Since we recently reported higher prevalence of mutations of the KCNJ5 gene and associations with autonomous cortisol secretion in Japanese aldosterone-producing adenomas than in Western countries, there might be different features of CPAs between Japan and the West. We therefore investigated mutations of the PRKACA gene in Japanese patients with several adrenal tumors secreting cortisol, including overt Cushing's syndrome, subclinical Cushing's syndrome, and aldosterone-producing adenomas (APAs) co-secreting cortisol operated on at Gunma University Hospital. Of the 13 patients with CPA who showed overt Cushing's syndrome, 3 (23%) had recurrent somatic mutations of the PRKACA gene, p.L206R (c.617 T>G), and there were no mutations in subclinical Cushing's syndrome. Among 33 APAs, 24 had somatic mutations of the KCNJ5 gene, either G151R or L168R, 11 (33%) had autonomous cortisol secretion, but there were no mutations of the PRKACA gene. We established a PCR-restriction fragment length polymorphism assay and revealed that the mutated allele was expressed at a similar level to the wild-type allele. These findings demonstrated that 1) the prevalence of Japanese patients with CPA who showed overt Cushing's syndrome and whose somatic mutations in the PRKACA gene was similar to that in Western countries, 2) the mutation might be specific for CPAs causing overt Cushing's syndrome, and 3) the mutant PRKACA allele was expressed appropriately in CPAs.

Abstract
UNLABELLED The biology and pathomechanism of bilateral breast cancers is not fully understood. We compared the morphological and immunohistochemical characteristics of primary tumors in patients with synchronous bilateral breast cancers and metachronous bilateral breast cancers, with special focus on intrinsic tumor phenotype. METHODS Tumor morphology and expression of 8 immunohistochemical markers were assessed in tissue microarrays containing primary breast tumor cores from 113 metachronous bilateral breast cancers and 61 synchronous bilateral breast cancers. Analyzed markers included hormone receptors (estrogen receptor, progesterone receptor), HER2, Ki67, cytokeratin 5/6, E-cadherin, vimentin and epidermal growth factor receptor. Cutoff levels are provided in the table. RESULTS Metachronous bilateral breast cancers tumors had lower estrogen receptor expression (p=0.047) and higher expression of cytokeratin 5/6 (p=0.017) and of vimentin (p=0.008); in multivariate analysis only vimentin retained the significance (p=0.01). Ten (13%) and 11 (26%) of metachronous bilateral breast cancers and synchronous bilateral breast cancers had luminal A phenotype, 39 (50%) and 15 (36%) were luminal B HER2-negative, 13 (17%) and 12 (28%) - luminal B HER2-positive, 3 (4%) and 2 (5%) - HER2-positive (not luminal), and 12 (16%) and 2 (5%) had triple negative phenotype (p=0.07). CONCLUSION Metachronous bilateral breast cancers, compared to synchronous bilateral breast cancers, are characterized by more aggressive phenotype, expressed by lower expression of estrogen receptor and stronger expression of cytokeratin 5/6 and vimentin; this does not, however, translate into differences in the distribution of intrinsic tumor phenotypes.

Abstract
OBJECTIVE To evaluate the clinicopathologic features of gastrointestinal stromal tumor (GIST) with synchronous carcinoma and the treatment principle. METHODS Nineteen cases of GIST with synchronous carcinoma were collected from 113 cases of GIST from 2002 to 2008. The clinicopathologic features were studied and the expression of CD117, CD34, smooth muscle actin and S-100 protein were detected by immunohistochemistry using EliVision method. The expression of proliferation marker Ki-67 was also studied. GIST with synchronous carcinoma and those without carcinoma were compared. RESULTS Nineteen cases (16.8%) of GIST with synchronous carcinoma were found, including 11 males and 8 females (male to female ratio 1.38: 1.00). The age of the patients ranged from 43 to 66 years (median age 57 years). Five of 19 cases were located in the inferior segment of esophagus and 14 were in the gastric wall. The diameter ranged from 0.6 to 3.8 cm [mean (1.91 ± 0.92) cm]. Three of 19 cases showed low grade dysplasia, and there was no dysplasia in the remaining 16 cases. The number of mitosis ranged from 0 to 4/50 HPF [mean (0.74 ± 1.07)/50 HPF]. The Ki-67 proliferative index (number of Ki-67 positive cell/HPF) ranged from 0 to 7.72% [mean (2.51 ± 2.20)%]. The synchronous carcinomas included two esophageal carcinomas and 17 gastric cancers.In contrast, patients of GIST without carcinoma included 52 males and 42 females (male to female ratio 1.24: 1.00). The age of patients ranged from 43 to 71 years (median age 55 years). Seventy-nine of the 94 cases were located in the stomach, 10 were in the intestine and 5 were in the esophagus. The diameter ranged from 2.4 to 15.5 cm [mean (5.42 ± 6.17) cm].Seventy-nine of the 94 cases showed variable degrees of dysplasia, and 12 cases were of high malignant potential. The number of mitosis ranged from 0 to 53/50 HPF [average (3.78 ± 10.22)/50 HPF]. The Ki-67 proliferative index ranged from 0 to 37.54% [mean (6.78 ± 12.45)%]. Comparing these two groups, the male to female ratio of GIST with synchronous carcinoma was higher than that of GIST without carcinoma. The average diameter of GIST with synchronous carcinoma was smaller than of those without carcinoma. The number of mitosis and Ki-67 proliferative index of GIST with synchronous carcinoma were significantly lower than those without carcinoma (t' = 2.809, P < 0.05; t' = 3.095, P < 0.05, respectively). CONCLUSIONS Sixteen point eight percent of GIST may be associated with synchronous carcinoma. There are no special clinical symptoms in most of GIST with synchronous carcinoma, as these GIST are usually incidental findings. The Ki-67 proliferative index of GIST with synchronous carcinoma is significantly lower than that of GIST without synchronous carcinoma. Most GIST with synchronous carcinoma can be treated by the standard treatment for the accompanying carcinoma, and do not require specific additional treatments.

Abstract
CONTEXT Pancreatic cancer is frequently complicated by malignancies in other organs. However, synchronous triple cancers including pancreatic cancer have been seldom reported in the English language literature. CASE REPORT We describe the rare case of a 77-year-old man with triple cancers of the pancreas, stomach, and cecum. Biopsies revealed that all three tumors were adenocarcinomas. The pancreatic and gastric tumors were positive for cytokeratin 7 and negative for cytokeratin 20, whereas the cecal tumor was negative for cytokeratin 7 and positive for cytokeratin 20. K-ras mutations were present at codon 12 in the pancreatic tumor and at codon 13 in the cecal tumor, but were absent from the gastric tumor. Since the three tumors had different characteristics, the patient was diagnosed with synchronous triple cancers. Because invasive surgery was required to remove all three tumors and the patient had risk factors for surgery, we elected to treat him with chemotherapy. All three cancers were markedly reduced in size by treatment with cycles of 100 mg/day S-1 for 2 weeks, followed by a 1-week rest. The patient later developed hypoproteinemia and anasarca, which was diagnosed as pancreatic exocrine insufficiency due to pancreatic head cancer. Treatment with pancrelipase resulted in dramatic improvements in hypoproteinemia and anasarca. CONCLUSIONS This is the first case report in which S-1 was effective in triple cancers of the pancreas, stomach, and cecum. Patients with pancreatic head cancer should be monitored for pancreatic exocrine insufficiency.

Abstract
Mycosis fungoides (MF) is a relatively rare cutaneous T-cell malignancy. Only two cases of MF with marked eosinophilia have been reported. In addition, MF with concomitant squamous cell carcinoma (SCC) occurring in the site of MF has not been reported. The author reports herein a very rare case of MF in the plaque stage showing pronounced eosinophilic infiltration, folliculotropic pattern, and in situ development of poorly differentiated squamous cell carcinoma (SCC). A 75-year-old man was found to show high prostate specific antigen (PSA, 13 hg/ml) and prostatic biopsy showed well differentiated prostatic adenocarcinoma of Gleason score 6. Imaging techniques showed no metastatic lesions. He was treated by estrogen therapy. At 80 years, he consulted our hospital because of erythematous patch in the trunk. Biopsy showed mild infiltrations of lymphocyte and eosinophils. The lesion disappeared spontaneously. At 82 years, he consulted our hospital of because of erythematous patch at the back, and biopsy showed mildly atypical lymphocytes positive for CD20 and CD45, but negative for CD30, CD45RO, S100 protein, and cytokeratin (CK). Lymphoma was suspected but not definite. The lesions spontaneously disappeared. At 86 ages, he also consulted our hospital because of plaques in the face. Biopsy showed proliferation of atypical lymphocytes, marked infiltration of mature eosinophils, marked infiltration of these cells in the fair follicles (folliculotropism), and poorly differentiated invasive SCC arising from follicular cells. An immunohistochemical analysis showed that the atypical lymphocytes are T-lymphoma cells with T-cell markers, cyclinD1, p53, and high Ki67 labeling (50%) but without B-cell markers, NK-cell markers and plasma cell markers. The eosinophils were mature, and lacked p53 and showed low Ki67 labeling (4%). The carcinoma was positive for CK, p53, cyclinD1, and high Ki67 labeling (35%). A diagnosis of MF in the plaque stage with marked non-neoplastic eosinophilic infiltration, marked folliculotropism, and coexistent poorly differentiated invasive SCC was made by the author. Post-biopsy imaging techniques showed no metastasis or lymphadenopathy in the body. The patient was now treated by chemotherapy.

Abstract
OBJECTIVE To explore the target protein expression in separate tumors in a patient with synchronous multiple gastric carcinomas (SMGCs). STUDY DESIGN Immunohistochemistry for HER2, EGFR, and MET were performed in 282 carcinomas from 141 patients. RESULTS Of 141 patients with SMGCs, 11.3%, 23.4%, and 14.9% of cases showed HER2, EGFR, and MET protein overexpression, respectively. In SMGC cases with overexpression of target proteins in > 1 tumor, intertumoral heterogeneity was 81.3% (13/16) for HER2, 78.8% (26/33) for EGFR, and 90.5% (19/21) for MET protein. The concordance rate of HER2, EGFR, and MET expression between 2 carcinomas from the same patient was 90.8%, 81.6%, and 86.5%, respectively, with a kappa value below 0.3, indicating slight to fair agreement. CONCLUSION We found a considerable intertumoral heterogeneity of target protein overexpression in SMGCs. Our findings support a multicentric origin for SMGC and emphasize the need to perform immunohistochemistry for all synchronous lesions.

Abstract
BACKGROUND Our purpose was to assess the clinicopathological features and surgical outcomes of combined hepatocellular-cholangiocarcinoma (HCC-CC) in an Asian center. METHODS Between 1998 and 2009, 27 patients were diagnosed with combined HCC-CC at our hospital. Their medical records were reviewed and clinicopathological data retrospectively analyzed. RESULTS The 27 patients included 24 (88.9%) males and 3 (11.1%) females with a mean age of 58.26 ± 11.18 years. Cirrhosis was present in 10 patients (37.0%), and 12 patients had hepatitis C or hepatitis B virus infection. Serum alpha fetoprotein was >20 ng/ml in 7 of the 19 patients in whom it was measured (36.8%). Twenty-five patients underwent hepatic resections and 2 received liver transplantations. Five (18.5%) patients had separate HCC and CC within the same liver (type I), 21 (77.8%) had tumors with mixed components (type II), and 1 patient had a type III tumor (3.7%). Of 22 patients with immunohistochemical data, 19 (86.4%) were cytokeratin (CK) 7-positive, 20 (90.9%) were CK19-positive, and 4 (18.2%) were CK20-positive. Mean follow-up was 25.8 months. The 1- and 2-year survival rates were 72.5 and 49.4%, respectively. The 1- and 2-year disease-free survival rates were 54.2 and 41.3%, respectively. Symptoms at the time of diagnosis, and regional lymph node metastases, were associated with higher mortality and recurrence. CONCLUSIONS Lymph node metastasis and positive resection margins are important factors affecting HCC-CC surgical outcomes.

Abstract
We report a case of large multiple brown tumors in a patient with primary hyperparathyroidism. A 52-year-old woman suffered from pain in the ribs and developed left facial swelling and deformity. CT showed a large destructive osteolytic lesion in the left maxillary sinus. Biopsy showed a lesion with newly formed bone tissue, diffuse giant cells and deposits of hemosiderin. In addition, similar lesions were also observed in the ribs, iliac bones and pelvis. The laboratory data showed hypercalcemia and hyperparathyroidism. Cervical echo and (201)Tl-(99m)TcO(4-) scintigraphy demonstrated a right lower swollen parathyroid adenoma. The diagnosis was multiple brown tumors with primary hyperparathyroidism and parathyroidectomy was performed. Follow-up CT showed marked decreases in the size of osteolytic lesions with calcification in the brown tumors compared to pre-treatment findings. These changes were associated with marked improvement in pain and facial deformity. We described a rare case of multiple brown tumors appeared in the maxilla associated with primary hyperparathyroidism.

Abstract
Papillary thyroid carcinoma (PTC) often presents with two or more anatomically separate foci. A long-standing argument is whether this multifocality is the result of multiple independent tumors ("multicentricity") or of intrathyroidal spread originating from a single tumor mass, presumably through permeation of intrathyroidal lymph vessels. We reexamined this issue with a clonality assay and compared our results with those in the literature. A total of 27 nodules from 11 female patients with bilateral PTC treated with total thyroidectomy were investigated for clonality using the HUMARA assay. Eight of 11 cases were informative (72.7 %). All but one of tumor foci showed a monoclonal population. The outlier sample gave a value indicative of balanced X-inactivation in one nodule. The monoclonality was concordant in three patients, discordant in three, and mixed in two (with both concordant and discordant results). Interestingly, in both of the latter cases (composed of over two samples per case), the contralateral nodules were discordant. Moreover, all four ipsilateral nodules were concordant. The results of our study suggest that some cases of multifocal PTC are the result of true multicentricity, whereas others are the consequence of intrathyroid spread by an originally single tumor mass. These conclusions support those made in the past years on the basis of morphologic considerations. Specifically, the incidental finding of two or more microscopic foci of PTC widely separate from each other was felt to favor multicentricity, whereas the finding of multiple ipsilateral foci of PTC within vascular spaces, often accompanied by multiple lymph node metastases, suggested intrathyroid spread; the most striking manifestation of this phenomenon being seen in the diffuse sclerosing variant of PTC.

Abstract
Head and neck paragangliomas that are exclusively or predominantly dopamine-secreting are rare. Surgery and/or radiotherapy are modalities for locoregional tumoral control. Little is known about the efficacy of radiotherapy for biochemical control in such tumors. We report a 62-year-old Chinese man with bilateral carotid body tumors which were exclusively dopamine secreting. The left-sided tumor invaded the skull base and encased the left carotid artery. Surgery was not performed due to high risk of morbidity and mortality. The patient received external beam radiotherapy to bilateral neck regions. Progressive decline and eventual normalization of urinary dopamine excretion was seen together with a slight reduction in tumor size. This is the first report demonstrating the efficacy of radiotherapy for both biochemical and locoregional control of functioning carotid body paragangliomas.

Abstract
We present an intriguing case of adrenal myelolipomata occurring within an adrenocortical adenoma in concert with an ipsilateral clear cell renal cell carcinoma. A 50-year-old female presented with dull right flank pain and hematuria. Computed tomography indicated a 2.5 cm right renal mass as well as a 5 cm right adrenal mass. Both masses were surgically resected concurrently. Histology of the renal mass was consistent with conventional clear cell renal cell carcinoma, Fuhrman grade III. There was no extra-renal extension or lymphovascular invasion. The adrenal mass was a cortical adenoma with solid and nested patterns, with discrete zones consisting of erythroid, myeloid and megakaryocytic cells intermixed with mature adipocytes. Mitoses were inconspicuous. The solid tumour component was strongly positive for vimentin, inhibin and CD56, focally positive for low-molecular-weight cytokeratin (Cam 5.2), calretinin and CD10 (chiefly in the myelolipomatous zones), and negative for chromogranin, S100, HMB-45, melan-A (A103), Mart-1, synaptophysin, SMA, CK7, CK20, ER, PR, TTF-1, CD99 and GCDFP (BRST-2). Ki67 (MIB1) staining indicated a low tumour proliferation index. Although well-described individually, a search of the English language literature suggests that this is the first such documented case of synchrony of these three lesions. We also present a relevant review of the literature pertaining to adrenal lesions. In particular, we emphasize the epidemiological, histological and immunohistochemical features that are helpful in determining the origin and malignant potential of adrenal lesions.

Abstract
In publication were discussed pathogenic mechanisms which are developed during concordance of malignant tumors of thyroid gland and reproductive systems and dishormonal hyperplasias, also functional disturbances which accompany thyroid gland diseases and principles of treatment during synchronic and metachronic manifestations. The treatment of polyneoplasias by "neurotransmitive control" is proposed. Importance of thyroid suppressive therapy was assessed. The efficacy of thyrotrophic hormone suppression by neurotransmitters in prevention of malignant tumors of reproductive system was reported.

Abstract
Primary lymphoepithelioma-like carcinomas (LELC) of the hepatobiliary tract are quite rare and the majority are associated with the Epstein-Barr virus (EBV). Here we report an unusual case of intrahepatic cholangiocarcinoma (ICC), admixed with LELC in a 63 year-old Filipino woman who presented clinically with right flank and back pain. Histologically, the tumor showed a dense lymphocytic infiltrate, predominantly composed of CD3 (+) T cells, and two components: an undifferentiated carcinoma, morphologically similar to nasopharyngeal carcinoma, and a poorly differentiated ICC intimately admixed. Immunohistochemical studies revealed that both components were immunoreactive for AE1/AE3, cytokeratin 7 and, focally, for monoclonal CEA. Both components were negative for cytokeratin 20 and HePar 1. EBER-1 in situ hybridization was uniformly positive in the tumor cells. The presence of EBV in ICC and LELC suggests that the virus may be linked to the pathogenesis of both components of the tumor. The mechanism of virus-driven neoplastic transformation needs further study.

Abstract
Sarcoid reactions are relatively rare manifestations of epithelioid cell granulomas associated with malignancy; they are especially found in the lymph nodes draining malignant tumors, but rarely found in other organs. We present a case of a 60-year-old female with sarcoid reactions in the spleen identified during the consecutive diagnosis and management of ovarian, breast, and thyroid carcinomas during a period of about 2 years. The symptoms and laboratory data suggestive of systemic sarcoidosis were absent except for a slight mediastinal lymphadenopathy detected only by a computed tomographic scan. The splenic granulomas were accompanied by dendritic cells of mature and immature types, the latter being different from the reported nodal counterparts. To our knowledge, this is the first reported case of splenic sarcoid reactions associated with multiple cancers, and the first reported immunohistochemical detection of dendritic cells in splenic granuloma.

Abstract
BACKGROUND Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasm affecting the gastrointestinal tract. The incidental occurrence of mesenchymal tumors and other primary tumors has not been well described in literature. OBJECTIVE The aim of this study was to evaluate the clinical and pathologic features of GIST occurring synchronously with other primary tumors. METHODS Forty-three patients with diagnosis of GIST treated surgically with curative intent at our institution from 1998 to 2006 were included. The patient clinical data and pathological reports were reviewed. RESULTS Of the 43 patients, there were 6 (14%) cases of synchronous GIST and other primary tumors discovered as coincidental findings. The synchronous GISTs analyzed were located in the stomach (50%) and small intestine (50%), size ranging from 0.7 to 7.6 cm (median 3.35 cm). Five (83%) of the concurrent primary tumors were from gastrointestinal origin and only one (17%) patient presented with concurrent breast cancer and GIST. The synchronous GISTs immunofenotype shows positivity for CD117 and CD34 (100%), smooth-muscle actin (SMA) (67%), S100 (50%) and desmin (33%). Whereas staining for cytokeratin AE1/AE3 and PDGF were all negative. According to GIST risk category for aggressive behavior three were classified as very low, one intermediate and two high. CONCLUSIONS The synchronous occurrence of GISTs and other primary neoplasm is not an uncommon entity and usually they are discovery incidentally. Epithelial tumors of the gastrointestinal tract are the most associated with concomitant GISTs. Further studies are required to clarify the molecular and genetic mechanisms of carcinogenesis and progression associating GIST and synchronous tumors.

Abstract
BACKGROUND Gastrointestinal stromal tumors (GISTs) are common mesenchymal neoplasms of the digestive tract and may occasionally arise within the abdomen without gastrointestinal tract connection. GISTs have recently attracted widespread interest because of the development of effective targeted molecular agents against it. While synchronous occurrence of a GIST with a tumor of different histogenesis was thought to be very rare, it is now apparent that they are more common than previously believed. PATIENTS AND METHODS We report our experience with GISTs and also six cases of GIST coexisting with other primary neoplasms. Using immunohistochemistry and mutational analysis, a possible correlation was investigated. A review of the literature was also conducted. RESULTS There were no significant differences in the immumohistochemical and molecular profile between single GISTs and GISTs coexisting with other tumors, nor was there any mutational correlation between GISTs and the coexistent tumors of different histogenesis regarding KIT and PDGFRA genes. CONCLUSION Further molecular biology studies are required in order to investigate thoroughly the simultaneous development of tumors with different histotypes.

Abstract
Metaplastic thymoma is an extremely rare tumor. To date, only 17 cases of metaplastic thymoma have been reported. To the best of the authors' knowledge, this is the second reported case of a sarcomatoid carcinoma arising in metaplastic thymoma; the carcinoma in this case is larger than that in the previous case. A 63-year-old woman with cough and asthenia for 2 weeks was admitted to the hospital. Computed tomography (CT) revealed a giant mass on the right side of the front mediastinum medium. The mediastinal tumor was excised, and additional pathological examinations, immunohistochemical tests, and electron-microscopic tests were performed. The tumor was diagnosed as a sarcomatoid carcinoma arising in metaplastic thymoma. Here, the authors discuss the clinical pathology of the sarcomatoid carcinoma arising in metaplastic thymoma and describe the biological behaviors with respect to the pathological features.
