Abstract
We identified cutaneous angiosarcomas in 10 children and assessed clinical (patient age, tumor site, tumor size, and tumor focality) and histologic features including growth pattern (vasoformative vs. solid), mitotic rate (mitotic figures per 10 high power field), necrosis (present vs. absent), and...

Abstract
We report a series of 13 cases of primary cutaneous epithelioid angiosarcoma and analyze their clinicopathologic features. The tumors arising in the conventional settings for cutaneous angiosarcoma (ie, in the head and neck region of elderly patients, and those occurring postradiation or associated...

Abstract
Morphologic features of KPs in various types of uveitis are diverse. Stippled and globular KPs may be observed in almost all types of uveitis. Certain types of KPs are more frequently associated with specific forms of uveitis, that is, smooth-rounded KPs may be an indicative of a granulomatous uveit...

Abstract
Epithelioid sarcoma is an uncommon malignancy that usually arises in the superficial soft tissues of the extremities. Classically, epithelioid sarcoma grows as nodules of mild to moderately atypical epithelioid cells, frequently with central necrosis. The stroma is variably fibrous and may rarely co...

Abstract
Fluorescence in situ hybridization (FISH) often reveals imbalanced chromosomal gains in melanoma, whereas Spitz nevi typically have a normal complement of chromosomes. However, there may be a subset of Spitz nevi that are perfectly tetraploid by FISH analysis, and these cases may be confused diagnos...

Abstract
We report 10 examples: 8 epithelioid glioblastomas (E-GBMs) and 2 rhabdoid GBMs (R-GBMs). E-GBMs tended to be superficially located, circumscribed, supratentorial tumors composed of monotonous, discohesive sheets of small rounded cells that mimicked metastatic malignant melanoma. R-GBMs showed tumor...

Abstract
We report a case of sclerosing epithelioid fibrosarcoma focusing on its cytological features in pleural effusion. A 32-year-old man had noticed a tumor in his left buttock 5 years earlier but had not sought treatment because the tumor had been painless. He visited our hospital because the tumor had...

Abstract
Crohn's disease (CD) can often present initially with extraintestinal manifestations and/or perianal disease. Cytology of such a lesion helps arrive at the diagnosis.
A 27-year-old woman presented with recurrent, painful, discharging perianal lesions. On examination, multiple perianal abscesses, sin...

Abstract
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: F...

Abstract
We report a 39-year-old man with SEF of the liver, which infiltrated the inferior vena cava (IVC). The SEF of the liver was successfully resected, and the infiltrated IVC was also removed together with the liver tumor. Histopathological examination of the tumor showed typical histopathology of SEF....

We describe 2 cases of malignant melanotic epithelioid renal neoplasms bearing TFE3 gene fusions. Both neoplasms occurred in children (an 11-y-old boy and a 12-y-old girl), and presented with disseminated metastatic disease including mediastinal and mesenteric adenopathy. Both neoplasms featured she...

Abstract
Sclerosing epithelial fibrosarcoma is a malignant mesenchymal tumor (fibroblastic class). It involved tissues of the legs and trunk in patients aged 31-59 and grew slowly as an infiltrative neoplasm during 6-18 months. Relapse occurred in 20% although no metastases were reported. Tumor consisted of...

Perivascular epithelioid cell tumour (PEComa) is a term applied to a family of mesenchymal tumours composed of varying proportions of spindle and epithelioid cell components associated with HMB-45 expression. PEComa rarely arises in the soft tissue, visceral organs, skin and bone. This report detail...
