There were no signs of recurrence after 1-year follow up since the operation. SUBCUTANEOUS SPINDLE CELL LIPOMA AND SUBCUTANEOUS PLEOMORPHIC LIPOMA The subcutaneous spindle cell lipoma is constituted by mature adipose tissue mixed with. The three principal components of spindle cell. S-100, CD34, and bcl-2 was able to differentiate these tumors and was very useful for the diagnosis of spindle cell lipoma. Spindle cell lipoma is a benign lipomatous lesion, and it was first introduced by Enzinger and Harvey (1). Differentiation of spindle cell lipoma includes solitary fibrous tumors, neurofibromas, subcutaneous fibrous malignancies, and well differentiated lipomas. Based on the pathological features, the diagnosis was spindle cell lipoma. In immunohistochemical staining, the adipocytes were positive to S-100, and the spindle cells showed positive for CD34 and bcl-2 but S-100 negative. The pseudoangiomatous pleomorphic/spindle cell lipomas were mostly found in the neck (seven patients) and shoulders (four patients), but have also been seen in. Spindle cell lipomas are benign lipomatous tumors that occur. The size of mature adipocytes was uniform, and nuclear atypia was not observed. The histo- logical examination was consistent with the diagnosis of a mature lipoma. We present a case of spindle cell lipoma occurring in the hypopharyngeal space, with protrusion of such with an intra-abdominal pressure increase. To our knowledge, only 24 cases of spindle cell lipoma involving the hypopharynx have been reported in PubMed. The histopathology showed that the well-demarcated mass was composed of mature adipocytes and spindle cells with bundles of collagen fibers. Spindle cell lipomas originating from the hypopharynx are rare. It primarily affects the shoulders, upper back, and back of the neck of men in the fifth. Although the majority of tumor cells in classical spindle cell lipoma exhibit bland spindle cell morphology, variable numbers of larger round cells with. The encapsulated yellow mass was removed under general anesthesia. Spindle cell lipoma is a slow-growing benign tumor of the subcutis. Therefore, biopsy was performed before removal operation, and the mass was diagnosed as no malignancy. However, the internal properties were non-uniform, and the vascular pattern was observed. Inside of the lesion was the same signal as adipose tissue, and the mass showed high signals at T1 and T2 weighted sequence in magnetic resonance imaging. Clinical and image examination revealed that the mass was encapsulated, well-circumscribed, smooth-surfaced, and soft. A 68-year-old man had a painless swelling of the floor of mouth. Spindle cell lipoma is an asymptomatic, slow-growing subcutaneous tumor that has a predilection for the posterior back, neck, and shoulders of older men.: 625 See also. We reported a rare case of spindle cell lipoma of the floor of mouth. Spindle cell lipoma is a rare variety of lipoma that usually appears in subcutaneous tissue, for example, the posterior neck, shoulders, and back region, in middle-aged and older males.
