Therefore, when radiological findings suggest lipogenic tumor but are different from those of lipoma, spindle cell lipoma as well as well-differentiated liposarcoma should be considered for differential diagnoses. Although expected sites of spindle cell lipoma are the posterior neck, shoulder region, and upper back, it may also arise in the lower extremity. From these histological findings, diagnosis of spindle cell lipoma was made. Angervall L, Dahl I, Kindblom LG, Save S. muscular spindle cell lipoma of the posterior neck, ex- tensive to the upper cervical spinal canal and posterior cranial fossa with mass effect on the left. In addition, immunohistochemical study showed positive staining for CD34. Low-grade fibromyxoid sarcoma and hyalinizing spindle cell tumor with giant rosettes: a. The condition is benign and careful identification of the lesion is necessary to avoid. Conclusions: There are several kinds of lipomas. Spindle cell lipoma is an extremely rare variant of the common lipoma. Histopathological examination revealed that the tumor consisted of spindle cells, collagen fibers, and lipocytes. The pathological diagnosis was intramuscular spindle cell lipoma in the left deltoid muscle. Because pathological findings of the tiny specimen obtained by needle biopsy showed lipogenic tumor and the possibility of well-differentiated liposarcoma could not be ruled out, wide excision was performed. The three principal components of spindle cell. These foci of myxoid change and spindle cells. Spindle cell lipoma is a benign lipomatous lesion, and it was first introduced by Enzinger and Harvey (1). Spindle cell lipomas show well-differentiated adipocytes, as in a typical lipoma, but in addition have foci of myxoid tissue with spindled cells. The tumor is most common in the posterior neck, shoulder, and back. The differential diagnosis includes spindle cell lipoma, angiolipoma. A soft tissue mass on the lateral aspect of the knee, measuring 5 x 6 cm in size, that had been noticed 1 year previously showed slightly lower signal intensities both on T1- and T2-weighted magnetic resonance images than those of subcutaneous adipose tissue. In the text by Allen, 1 spindle cell lipoma was found 11 times in 87 000 accessions. 13.9 Myolipoma with a mixture of elongated eosinophilic smooth muscle cells and. A rare case of spindle cell lipoma of the knee in a 58-year-old woman is presented.
