Gastrointestinal Stromal Tumor: Chondro-Myxoid Variant Mimicking Chondrosarcoma
SW, an 84-year-old African American female, presented to an outside institution complaining of dull, intermittent abdominal pain in the anterolateral and suprapubic regions. Decreased appetite, nausea, and general weakness accompanied this pain. Physical exam revealed a soft, non-tender mass in the left upper quadrant that extended 20 cm below the costal margin. A separate 2 cm mass, in the per...
متن کاملGastrointestinal Stromal Tumor (GIST) with Chondroid-Myxoid-Chordoid Features Mimicking Extraskeletal Myxoid Chondrosarcoma
Epithelioid gastrointesinal tumors (GISTs) are less likely to have c-kit gene mutations (and express CD117) than spindle cell GISTs. CD117 negative/c-kit negative GISTs can have platelet-derived growth factor alpha (PDGFRα) gene mutations, overexpress PDGFRα protein and respond to imatinib mesylate. Many cases of CD117-negative/CD117weakly positive, c-kit mutation negative and PDGFRα mutation p...
متن کاملSclerosing Stromal Tumor: A Rare Ovarian Neoplasm
Ovarian sex cord-stromal tumors are relatively infrequent neoplasms that account for approximately 8% of all primary ovarian neoplasm. Sex cord-stromal tumors of the ovary include granulosa cell tumors, fibrothecomas, Sertoli-Leydigcell tumors, steroid cell tumors, and sclerosing stromal tumors (SST). Sclerosing stromal tumors account for 2% to 6% of ovarian stromal tumors. Despite the rarity o...
متن کاملDesmin expression by a gastrointestinal stromal tumor in a dog
This report describes the histological and immunohistochemical features of a small intestinal tumor that resembled a human gastrointestinal stromal tumor (GISTs) in a seven-year-old male cross-breed dog. This was unique because of the expression of desmin by the tumor. Grossly, the white-gray tumor measured 8.0 × 4.0 × 6.5 cm and was 760 gram in weight. It was cystic and enveloped the jejunum. ...
متن کاملPlexiform myxoid gastrointestinal stromal tumor: a potential diagnostic pitfall in pathological findings.
Gastrointestinal stromal tumors (GISTs) have a rather wide morphologic spectrum. Here, we report a rare variant plexiform GIST in gastric antrum. Microscopically, the tumor showed plexiform or multinodular growth pattern, proliferation of spindle cells, presence of epithelioid cells, and abundant myxoid stroma with thin-walled blood vessels. The histologic features were similar to plexiform fib...
