Spindle cell/pleomorphic lipoma is an uncommonly encountered benign neoplasm that is usually found in the subcutaneous tissues. Rare cases reported in the literature have an intradermal location. This lesion usually presents as a subcutaneous nodule on the neck, shoulders, or back of middle-aged to elderly males. Although spindle cell and pleomorphic lipoma are currently considered the same entity, they were historically categorized separately. The authors report a case of hyperpigmented papule with an associated subcutaneous nodule on the left cheek of a 56-year-old man, review the literature, and discuss several important diagnostic pitfalls of spindle cell/pleomorphic lipoma.
梭形细胞/多形性脂肪瘤是一种罕见的良性肿瘤,通常位于皮下组织。文献中报道的罕见病例位于真皮内。该病变通常表现为中年至老年男性颈部、肩部或背部的皮下结节。尽管梭形细胞脂肪瘤和多形性脂肪瘤目前被认为是同一实体,但在历史上它们是分别分类的。作者报告了一例56岁男性左脸颊出现色素沉着丘疹并伴有皮下结节的病例,回顾了相关文献,并讨论了梭形细胞/多形性脂肪瘤的几个重要诊断陷阱。
