Summary • Sarcoma is a rare cancer that can occur anywhere in the body, but more frequently in the extremities, chest and abdomen. • Incidence of sarcoma increases with age, some sarcoma types occur frequently in specific age groups. • Some sarcoma types resemble certain tissue types, and some need additional ancillary tests to confirm their identity.

PEComa may be part of the tuberous sclerosis syndrome and may show either a predominantly epithelioid or spindle morphology or combination thereof. Rarely, it may contain melanin pigment. There is.

Gastrointestinal stromal tumors (GIST) appear to originate from interstitial cells of Cajal (ICC) or their stem cell-like precursors.[1,2] ICC are pacemaker-like intermediates between the GI autonomic nervous system and smooth muscle cells regulating GI motility and autonomic nerve function.[3,4] KIT-positive and KIT-dependent, ICC are located around the myenteric plexus and the muscularis propria.

The patient made a good recovery and was discharged shortly afterwards, and owing to the local hospital diagnosis of gastrointestinal stromal tumor (GIST) he was referred to our tertiary center. The diagnosis was revised to clear cell sarcoma-like tumor of gastrointestinal tract, as below.

Summary. Epithelioid sarcoma is a rare sarcoma that affects young adults with an affinity to the distal upper extremity (hand and forearm). It mostly starts as a painless slow growing mass, but not uncommonly presents as a multifocal lesion. It has a high tendency for recurrence and spread along lymphatic channels.

Clear cell sarcoma is an uncommon sarcoma which rarely occurs as a primary tumour in the gastrointestinal tract (CCS-GIT). It shares common molecular genetic abnormalities with the more recently described entity, malignant gastrointestinal neuroectodermal tumour (GNET) but is distinguished by its morphological and immunohistochemical findings.

The summary below outlines the staining results from a range of antibodies. The Ki-67 index is a marker for cellular proliferation and was calculated to be approximately 20% indicating a non-aggressive growing neoplasm. Extra-intestinal epithelioid gastrointestinal stromal tumour (GIST), an.

PEComa may be part of the tuberous sclerosis syndrome and may show either a predominantly epithelioid or spindle morphology or combination thereof. Rarely, it may contain melanin pigment. There is.

The stages for gastrointestinal stromal tumors (GIST) range from stages I (1) through IV (4). As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more. And within a stage, an earlier letter means a lower stage.

Cell types in GIST: The pathologist will describe the GIST cells’ shape as spindle, epithelioid, or mixed. Overall, about 70% of GISTs are composed of spindle cells (long and skinny in shape, sometimes called fusiform), while 20% are composed of epithelioid cells (round or.

Epithelioid angiomyolipoma is an uncommon mesenchy-mal tumor with malignant potential, frequently associated with tuberous sclerosis complex. Histologically, EAML is characterized by sheets or nests of large polygonal epithelioid cells with abundant eosinophilic or occasion-ally clear cytoplasm, often with prominent nucleoli, and
