梭形细胞/多形性脂肪瘤是一种罕见的良性肿瘤，通常见于皮下组织。文献中报道的罕见病例有皮内位置。这种病变通常表现为中老年男性颈部、肩部或背部的皮下结节。尽管梭形细胞和多形性脂肪瘤目前被认为是同一实体，但它们在历史上是分开分类的。作者报道了一名 56 岁男性左脸颊色素沉着过度丘疹并伴有皮下结节的病例，回顾了文献，并讨论了梭形细胞/多形性脂肪瘤的几个重要诊断陷阱。
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.
