HistopathologyCutaneous piloleiomyoma (PLM), angioleiomyoma, and genital leiomyoma are variants of superficial cutaneous leiomyoma (CL). The classic appearance of a CL on hematoxylin and eosin staining is an unencapsulated, circumscribed dermal tumor composed of interlacing fascicles of spindle cells with a moderate amount of eosinophilic cytoplasm and a blunt-ended, elongated, cigar-shaped nucleus with perinuclear halos on crosssection; there is sometimes nuclear pleomorphism or a small number of mitoses, but the tumor retains its benign character (Fig. 1A). 1
