Abstract
Leiomyosarcoma of the stomach is a very rare malignancy that was not distinguished from the more frequent gastrointestinal stromal tumors until early 2000s. Here we report on a case of a metastatic disease that developed in a 47-year-old man 2 years after he was diagnosed with the primary tumor and treated with curative surgical excision and adjuvant doxorubicin. The primary and metastatic lesions were positive for smooth muscle markers α-smooth muscle actin and h-caldesmon and negative for CD117, DOG-1 and S100 by immunohistochemistry. Metastatic disease progressed on additional monotherapy with doxorubicin and docetaxel-gemcitabine combination, and stable disease was achieved upon treatment with pazopanib. Patient is surviving 35 months since diagnosis of the primary tumor and 11 months since diagnosis of metastatic disease.
