Adrenocortical tumors with myxoid features: a distinct morphologic and phenotypical variant exhibiting malignant behavior.
Myxoid changes have been rarely reported both in adrenocortical adenomas and carcinomas. The recent observation by our group of an adrenal myxoid tumor with morphologically borderline features, but aggressive clinical behavior prompted us to review a series of 196 adrenocortical lesions, comprising 122 carcinomas and 74 adenomas, to define the morphologic, phenotypical and clinical characterist...

متن کاملMyxoid variant of peritoneal epithelioid malignant mesothelioma. A case report.
The myxoid variant of a diffuse malignant epithelioid mesothelioma is a rare tumor. To the best of our knowledge, only three cases of this type of mesothelioma involving the peritoneum have been reported in the literature to date. Although it is rare in the peritoneal cavity, it should be included in the differential diagnosis of the more common myxoid/mucinous abdominal lesions (e.g. mucinous ...
متن کاملAnorectal malignant melanoma: morphologic and immunohistochemical features.
We reviewed 17 cases of primary anorectal malignant melanoma. Morphologic features evaluated included junctional change, pigmentation, morphology, and mitotic rate. Immunohistochemical stains were performed for/with S-100 protein, HMB-45, MelanA, tyrosinase, vimentin, KIT, and pankeratin. Morphologic subtypes were as follows: epithelioid, 12 cases; spindle cell, 7 cases; lymphoma-like, 10 cases...
متن کاملGenotype analysis of the human endostatin variant p.D104N in benign and malignant adrenocortical tumors
OBJECTIVE Endostatin is a potent endogenous inhibitor of angiogenesis. It is derived from the proteolytic cleavage of collagen XVIII, which is encoded by the COL18A1 gene. A polymorphic COL18A1 allele encoding the functional polymorphism p.D104N impairs the activity of endostatin, resulting in a decreased ability to inhibit angiogenesis. This polymorphism has been previously analyzed in many ty...
