title: Large intramuscular spindle-cell lipoma. With review of the literature. A case report.
abstract: A case of a large spindle-cell lipoma in an intramuscular (subfascial) localization is reported. The tumour occurred in a 58-year-old male patient and was localized subfascially in his left deltoid muscle. The tumour measured 20 X 8 X 8 cm; its weight was 780 grams. After initial biopsy, the tumour was extirpated. Microscopically, the tumour tissue consisted of mature fat cells and spindle-cell areas in varying amounts, constituting a typical appearance of a spindle-cell lipoma. There were no histological signs of malignancy. Especially, no areas of liposarcoma differentiation were detected. The patient is well, with no signs of recurrence, one and a half years after the operation. We have reviewed the literature on spindle-cell lipoma, and we believe this is the first example of this neoplasm to be reported in an intramuscular (subfascial) localization.
