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 ...
Histopathologic examination of the tumors in IMT generally reveals myofibroblastic spindle cell sheets in a myxoid background (i.e. a background matrix containing gelatinous mucopolysaccharides and non-sulfated glycosaminoglycans); the matrix also contains inflammatory cells, particularly plasma cells and lymphocytes occasionally mixed with ...

Spindle cell lipoma is most frequently located in the upper back, shoulder, or posterior neck subcutaneous layer. [3] Nonetheless, reports of it occurring in the mediastinum , hypopharynx , larynx , anterior neck, suprasellar region, esophagus , nasal vestibule , tongue, floor of mouth, vallecula, parotid gland , and breast have been made.

Two cell types can be seen microscopically in synovial sarcoma. One fibrous type, known as a spindle or sarcomatous cell, is relatively small and uniform, and found in sheets. The other is epithelial in appearance. Classical synovial sarcoma has a biphasic appearance with both types present.
Hemangiopericytomas are tumors that are derived from specialized spindle shaped cells called pericytes, which line capillaries. [4] Hemangiopericytoma is an aggressive mesenchymally derived tumor with oval nuclei with scant cytoplasm. There is dense intercellular reticulin staining. Tumor cells can be fibroblastic, myxoid, or pericytic. These ...
