We describe an unusual dermal neoplasm with epithelioid morphology. A 44-year-old man presented with a solitary, tender, 4-mm nodule on the leg. Excisional biopsy showed several well-circumscribed dermal epithelioid tumor nodules, prominent vascularity, and smooth muscle differentiation. We suggest the term cutaneous epithelioid angioleiomyoma for this neoplasm. In a review of the literature, we found reports of two similar cases and a recent report describing five cutaneous epithelioid leiomyosarcomas. Cutaneous epithelioid angioleiomyoma represents a rare variant of dermal smooth muscle tumor and could represent the benign counterpart to the recently described epithelioid leiomyosarcoma of the skin.
我们描述了一种具有上皮样形态的罕见皮肤肿瘤。一名44岁男性患者腿部出现一个孤立、触痛的4毫米结节。切除活检显示有几个边界清晰的皮肤上皮样肿瘤结节、明显的血管形成以及平滑肌分化。我们建议将这种肿瘤命名为皮肤上皮样血管平滑肌瘤。在文献回顾中，我们发现了两例类似病例的报告以及一篇近期描述五例皮肤上皮样平滑肌肉瘤的报告。皮肤上皮样血管平滑肌瘤是皮肤平滑肌肿瘤的一种罕见变体，可能是最近描述的皮肤上皮样平滑肌肉瘤的良性对应物。
