BACKGROUND
Sarcomas are a type of malignant tumors that arise from connective tissue. They are most of the time found in extremities
METHODS
We are presenting a case of adult male patient, who was found to have huge abdominal mass and multiple gastric and duodenal polyps. Pathological diagnosis for all lesions was Alveolar soft part sarcoma. Although he complained from metastasis to both lungs and right atrium, all these deposits regressed spontaneously. Patient stated that he used some herbs (Teucrium polium, Cat Thyme) prescribed for him. No chemotherapy or radiotherapy was given. The duration of regression was about 5 months before other lesions appeared. Later on, he died secondary to brain metastasis.
CONCLUSIONS
ASPS is a rare type of sarcomas that affect primarily the lower limbs. This tumor does rarely metastasize to the gastrointestinal tract.
