Other variants of lipomas include neural fibrolipomas, intramuscular and intermuscular lipomas, angiolipoma, and
spindle cell lipoma (1, 14).
Spindle cell lipoma: a benign lipoma variant with potential hazards of diagnostic misinterpretation.
[17] Other rare D/D's with adipocyte clusters in the aspirates are Lipomatous PA, Sialolipoma, Oncocytic lipoadenoma, Lipomatosis and
Spindle cell lipoma. [18] Tuberculous involvement of parotid is extremely rare, can present as indolent parotid enlargement and generally overlooked.
Histologically, lipomas are classified as classic lipoma, fibrolipoma, intramuscular lipoma (IML), angiolipoma, and
spindle cell lipoma. OL usually presents as a slow-growing painless mass that rarely exceeds 20 mm in diameter [3].
According to microscopic characteristics, lipomas are classified as classic lipoma, fibrolipoma, angiolipoma,
spindle cell lipoma, pleomorphic lipoma, myxoid lipoma, sialolipoma, and intramuscular lipoma.
Spindle Cell Lipoma.--Spindle cell lipoma is a benign tumor composed of bland spindle cells admixed with mature adipose tissue in a background of thick and ropey collagen.

spindle cell lipoma. Am J of Surg Pathol 1998;22:6-16.
The histologic differential diagnosis includes
spindle cell lipoma, nuchal-type fibroma, and fibromatosis.
In the histopathological examination,
spindle cell lipoma shows short stubby nuclei, ropey collagen, and variable proportions of fat.
Spindle cell lipoma (SCL) is an uncommon variant that has a characteristic clinical setting.

Microscopic examination revealed a
spindle cell lipoma, with no evidence of malignancy.
