Abstract

A 43-year-old man developed an abnormal scar 6 months following excision of a leiomyoma from his left shoulder. The scar was elevated, irregular in shape, pink-red in colour, hard in consistency and it was extending beyond the margins of the original wound. A diagnosis of a keloid scar was considered and the patient was managed as such. He underwent a planned procedure for intralesional excision of the keloid scar. The histopathological examination showed a diagnosis of leiomyosarcoma. This case report presents a delayed diagnosis of dermal leiomyosarcoma mimicking a keloid scar. The patient subsequently underwent wider excision of the tumour with curative intention.

Keywords: dermatology; pathology; plastic and reconstructive surgery.
