  • Title: [Cutaneous angiolipoleiomyoma: a case report and literature review].
    Author: Squillaci S, Marchione R, Spairani C, Soccio M, Tallarigo F.
    Journal: Pathologica; 2008 Feb; 100(1):36-40. PubMed ID: 18686525.
    Abstract:
    The Authors describe a rare case of cutaneous angiolipoleiomyoma in an acral location together with a brief literature review. A 62-year-old male presented with a slow-growing asymptomatic nodule, 2.2 cm in diameter, located in the subcutaneous tissue of the left calf. Ten months after surgical excision, the patient is alive and free of disease. Histologically, the lesion was well-circumscribed and contained three components: areas of mature fat tissue were intermingled with cellular areas of spindle eosinophilic cells, reminiscent of smooth muscle cells, and a complex mixture of vessels of different types and sizes. Immunohistochemically, the cellular spindle component was positive for vimentin and smooth muscle actin, and negative for S-100, HMB-45, MART-1 and oestrogen and progesterone receptors. The Authors discuss differential diagnosis with other benign lesions such as angioleiomyoma and subcutaneous angiomyolipoma.
