Nipple leiomyoma: a rare neoplasm with a broad spectrum of histologic appearances

Cutaneous leiomyomas are rare benign smooth muscle tumors. These lesions are differentiated based on their cell of origin and are sub‐classified as pilar leiomyoma, angioleiomyoma, and genital leiomyoma. Nipple leiomyomas are the least common genital leiomyoma, arising from the dartoic muscle cell of the nipple. Histologic examination of the lesion is necessary for definitive diagnosis, and these uncommon tumors can pose a diagnostic challenge. We describe herein a series of six nipple leiomyomas with a spectrum of histologic appearances.
