Subcutaneus leiomyosarcoma of the neck: a case report

INTRODUCTION: Leiomyosarcomas are rare tumors. The most common site for head and neck leiomyosarcomas is the oral cavity, followed by sinonasal tract and skin. Subcutaneous leiomyosarcomas are thought to arise from small to medium-sized blood vessels in the subcutaneous tissue. CASE PRESENTATION: A 67-year-old female patient underwent excision of a slow growing neck mass of the left posterior neck triangle after a thorough clinical and laboratory examination. The lesion was located in the subcutis and fine needle aspiration biopsy revealed malignant features. Histology revealed subcutaneous leiomyosarcoma and the patient is free from local recurrence and distant metastases 3 years after wide excision of the lesion. CONCLUSIONS: The primary modality of therapy of subcutaneous leiomyosarcoma is surgery, adjuvant radiotherapy or chemotherapy may be used for control of local recurrence, in case of positive surgical margins, high-grade or large tumors.
