Metastatic uterine leiomyosarcoma to the submandibular gland.
Metastasis of uterine leiomyosarcoma to the salivary glands is exceedingly rare. In this report, we present the clinicopathologic features of one such case. The patient was diagnosed with uterine leiomyosarcoma at age 58 years and was treated by hysterectomy only. The tumor was confined to the uterine body. The patient remained free of disease for 4 years and then developed a left submandibular mass. Imaging studies also showed lung involvement but no tumor in the abdomen or pelvis. The submandibular mass was resected; it had histologic and immunohistochemical features similar to those seen in the previous uterine leiomyosarcoma. After 7 months of follow-up, the patient is alive with disease, with progression of disease in the lungs despite receiving chemotherapy.
