[Primary granulocytic sarcoma of the peritoneum: a case report and literature review].

Granulocytic sarcoma is a rare tumor composed of immature granulocytic cells. Prognosis is poor. The periosteum is preferentially involved. A peritoneum localization is unusual. We report the case of a 20 years old man without particular previous pathologies, which brutally presented an ascitic syndrome in a context of health impairment state. The laparoscopy showes many white nodules on all the peritoneum. The histologic examination of one of these nodules showed granulocytic sarcoma. The blood and bone marrow cell count are without any anomaly. The treatment consisted of a standard acute myeloid leukaemia's chemotherapy with very good evolution. The rarity of peritoneal chloroma causes a diagnostic problem, especially in the absence of hematologic abnormalities. It must be mentioned in the presence of peritoneal nodules even if the blood count and bone marrow are normal.
