Zosteriform cutaneous leiomyoma: a case report

Cutaneous leiomyomas are rare, benign soft tissue tumors arising from smooth muscles of the skin and comprise of three distinct subtypes, namely piloleiomyoma, angioleiomyoma and genital leiomyoma. Piloleiomyomas can present as solitary form, multiple disseminated and zosteriform or segmental forms. Cutaneous leiomyomas are rare, of which zosteriform leiomyoma is not commonly encountered. Here we report an uncommon case of Type I zosteriform cutaneous leiomyoma in a middle-aged individual which was confirmed on histopathology. Patient was further started on nifedipine with significant symptomatic improvement. The patient is planned for surgical excision and long-term follow in view of its association with aggressive renal malignancy.
