Histiocytic sarcoma (HS) is an exceedingly uncommon lymphohematopoietic tumor characterized by an aggressive clinical trajectory and poor treatment response. The diagnosis depends on verifying its histiocytic origin and ruling out other undifferentiated cancers. Hodgkin's Sarcoma is often located in lymph nodes, with the gastrointestinal tract being the most prevalent extranodal location. As of yet, only a limited number of stomach histiocytic sarcomas have been documented. We discuss the case of a 64-year-old patient who exhibited persistent abdominal discomfort for two months and significant decline in overall health. The findings from oesophagogastroduodenal fibroscopy and biopsy, corroborated by immunohistochemistry analysis, indicated stomach histiocytic sarcoma. The thoraco-abdomino-pelvic CT scan indicated a stomach tumor with metastasis to the liver. The patient was sent to oncology for chemotherapy treatment. Timely identification and precise diagnosis of this uncommon neoplasm are crucial, since they might influence patient prognosis. The collection and assessment of stomach histiocytic sarcomas is crucial for advancing prognosis and therapeutic therapy.
