Cutaneous angioleiomyomas (ALMs) (also known as vascular leiomyomas or angiomyomas) are unusual benign tumors of the skin deriving from the muscle layer of dermal blood vessels. They usually manifest as tender subcutaneous nodules, mostly encountered on the legs of adult women in their fifth or sixth life decade. ALMs rarely develop on the head/neck area, and even more rarely (<3% of all cases) on the auricle. Head/neck (including ear) ALMs differ from their more usual leg counterparts in that they are usually painless and do not show a female predominance. The diagnosis is clinically difficult, and most cases are diagnosed by histopathologic examination. A new case of an auricular ALM in a 40-year-old Caucasian man is reported herein, and a brief literature review on this unusual tumor is presented.
皮肤血管平滑肌瘤(ALM)(也称为血管平滑肌瘤或血管肌瘤)是一种罕见的皮肤良性肿瘤,起源于真皮血管的肌层。它们通常表现为压痛性皮下结节,多见于50或60岁成年女性的腿部。ALM很少发生于头颈部区域,更罕见于耳廓(占所有病例的<3%)。头颈部(包括耳部)的ALM与更常见的腿部ALM不同,前者通常无痛,且无女性优势。临床诊断困难,大多数病例通过组织病理学检查确诊。本文报告了一例40岁白种男性耳廓ALM的新病例,并对这种罕见肿瘤进行了简要文献综述。
