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.

Pleomorphic lipomas, like spindle-cell lipomas, occur for the most part on the backs and necks of elderly men and are characterized by floret giant cells with overlapping nuclei. [7]: 625 Spindle-cell lipomas are asymptomatic, slow-growing, subcutaneous tumors that have a predilection for the posterior back, neck, and shoulders of older men.
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
Most cases of pleomorphic lipoma are seen in the subcutaneous tissue of the back, shoulder, and posterior neck. [2] Less commonly, it can also happen in odd places like the tongue, [3] vulva, [4] palm, [5] tonsillar fossa, [6] orbit, [7] and oral cavity. [8] The lesion usually presents as a subcutaneous lump that is circumscribed, like the ...
Spindle cell variant: Spindle cell lipoma combined with hibernoma; Histochemistry. Oil Red O-positive droplets of cytoplasmic lipid can be seen in most cases.
Cellular angiofibroma (CAF) is a rare, benign tumor of superficial soft tissues that was first described by M. R. Nucci et al. in 1997. [1] These tumors occur predominantly in the distal parts of the female and male reproductive systems, i.e. in the vulva-vaginal and inguinal-scrotal areas, respectively, or, less commonly, in various other superficial soft tissue areas throughout the body.

Your location — the state, city and even the part of town where you live. The type of car you drive — make and model, as well as the age and safety features.
The histopathological appearance of DDL tumors (see Fig. 2 in the below Histopathology of liposarcomas section) varies widely but most frequently exhibits features of undifferentiated pleomorphic sarcomas (which are tumors densely populated with variably sized and shaped cells containing variability sized and shaped nuclei) or spindle cell ...
