Spindle cell sarcoma is a type of connective tissue cancer. The tumors generally begin in layers of connective tissue, as found under the skin, between muscles, and surrounding organs, and will generally start as a small, inflamed lump, which grows in size. At first, the lump is, small in size, as the tumor exists in stage 1, and will not ...
[12] [13] While multinucleate cells are negative for other monocyte/macrophage lineage markers, they are significantly positive for vimentin. [11] [13] CD68 expression can be either positive [11] or negative. [13] [12] In interstitial and perivascular spindle cells, as well as rarely in multinucleate cells, estrogen receptor α has significant ...
ERMS is characterized by spindle-shaped cells with a stromal-rich appearance, and the morphology is similar to the developing muscle cells of a 6- to 8-week-old embryo. Tumors often present in the head and neck, as well as the genitourinary tract. [citation needed]
Spindle cell carcinoma is a type of cancer that begins in the skin or in tissues that line or cover internal organs and that contains long spindle-shaped cells. It is also called sarcomatoid carcinoma .
In neurobiology, spindle cell refers to: Spindle neuron, also known as a von Economo neuron; In general medicine, a spindle cell may refer to the spindle-shaped cells that are found in certain types of tumor: Inflammatory fibroid polyp; Pigmented spindle cell nevus; Spindle cell carcinoma; Spindle cell lipoma; Spindle cell sarcoma
Inflammatory pseudotumour is a generic term applied to various neoplastic and non-neoplastic tissue lesions which share a common microscopic appearance consisting of spindle cells and a prominent presence of the white blood cells that populate chronic or, less commonly, acute inflamed tissues.

Sarcomatoid carcinoma is a type of rare lung tumour under the category of poorly differentiated Non-small-cell lung carcinoma (NSCLC). Based on its histological characteristics, it can be classified into giant cell carcinoma (almost completely consists of giant cells), spindle cell carcinoma (almost completely consists of spindle cells), pleomorphic carcinoma (at least 10% spindle/giant cells ...
Microscopy of tumors in the spindle cell lipoma tentative variant of MFB show a mixture of mature fat cells, ropey collagen, and spindle cells in a myxoid (i.e. background connective tissue that stains blue or purple rather than the red of normal connective tissue) matrix. [18] The blood vessels in these tumors often appear hyalinized. [16]
