Leiomyosarcoma of the parotid gland metastatic to the scalp: A rare primary location with unusual metastatic lesion

Abstract

We are reporting an extremely rare case of leiomyosarcoma of the parotid gland in a 33-year-old-woman, who was initially treated with surgery and post-operative radiotherapy. The patient developed an isolated metastatic lesion in the scalp region 15 months after treatment of her primary disease. The scalp lesion was surgically excised and radiotherapy was given. Currently, she remains disease free 4 years and 9 months following the diagnosis of her metastatic disease. Scalp metastasis from leiomyosarcoma of the parotid gland has not been reported. In fact, scalp metastasis from leiomyosarcoma of any other anatomic site or from any malignant tumor of parotid gland has not been mentioned in the literature.
