Secondary acute promyelocytic leukemia following chemotherapy for gastric cancer: A case report

Figure 1 Upper abdomen computed tomography scan. A: Plain computed tomography (CT) indicated a localized, irregularly-shaped mass in the stomach; however, no obvious lymph node metastasis was observed; B: Contrast-enhanced CT scan revealed inhomogeneous enhancement of the gastric wall lesion; C, D. Biopsy results pathologically confirmed the diagnosis of a poorly differentiated adenocarcinoma. Microscopic examination revealed obvious atypical nuclei and large, bizarre, multinucleated cell mitosis. Generally, the normal structure of gastric gland was lost.
