ABSTRACT
Smooth muscle tumours arising in the skin are divided into angioleiomyomas, genital leiomyomas and pilar leiomyomas. Limited data about solitary leiomyoma are available in the literature. We herein report a case of a 66-year-old man who presented to our department with a slowly progressing cutaneous tumour of the right scapular area that had developed over the past 12 years. Histopathological and immunohistochemical results were consistent with the diagnosis of pilar leiomyoma. Pilar leiomyoma is a benign smooth muscle tumour arising from arrector pili muscle. Tumours can be painful from compression of cutaneous nerves or because of fibre contraction within the tumour in case of cold weather or emotional stress. This case is noteworthy as the piloleiomyoma was solitary, located on the trunk and had an unusual nipple aspect.
