Core Tip

Core Tip: This case report describes a gastric primary de novo myeloid sarcoma (MS) which is a very rare hematological neoplasm with poor prognosis in a young and symptomatic patient. After receiving chemotherapy, she presented severe toxicity (neutropenic typhlitis) and rapid disease progression. This case highlights the importance of detecting gastric primary MS as a rare form of extramedullary myeloid leukemia presentation. Moreover, management of gastric primary MS could lead to interventions to avoid deterioration of gastrointestinal system during treatment. There is limited information of management and outcomes regarding gastric primary MS. Furthermore, there is very limited data about de novo MS in Peruvian patients.
