sarcomatoid การใช้
- Rare subtypes include carcinoid tumors, bronchial gland carcinomas and sarcomatoid carcinomas.
- Under the 2nd revision ( 1981 ) of the WHO classification, it was considered a subtype of sarcomatoid carcinomas ".
- Rarely, CUP may appear as neuroendocrine tumors, or mixed tumors, such as sarcomatoid, basaloid, or adenosquamous carcinomas.
- Rarely, spermatocytic seminomas may show sarcomatoid differentiation, most commonly as undifferentiated spindled cells intermingled within the typical-appearing spermatocytic seminoma cells.
- Sarcomatoid carcinomas are unique among lung carcinomas in that, although they are considered carcinomas, they contain cytological and tissue architectural features that are usually characteristic of sarcoma.
- A spindled component is characteristic of MTSCC, but the presence of significant pleomorphism with prominent nucleoli and mitotic activity, and necrosis should raise concern for a sarcomatoid change.
- However, as certain types of tumors ( such as sarcomatoid mesothelioma ) do not release SMRP, the FDA recommends that doctors use the MESOMARK assay in conjunction with other tests to ensure an accurate mesothelioma diagnosis.
- Finally, some rare forms of breast cancer ( e . g ., sarcomatoid carcinoma, histological grade, presence of cancer in small vessels ( vascular invasion ), expression of hormone receptors and of oncogenes like HER2 / neu.
- Some of the more well known include the lesions containing pseudo-sarcomatous components : spindle cell carcinoma ( containing elongated cells resembling connective tissue cancers ), giant cell carcinoma ( containing huge, bizarre, multinucleated cells ), and sarcomatoid carcinoma ( mixtures of spindle and giant cell carcinoma ).
