Endoscopic submucosal dissection (ESD) has been successfully performed in thrombocytopenic conditions such as in patients with liver cirrhosis but successful ESD for early gastric cancer (EGC) in hematologic diseases has rarely been reported. A 52-year-old male patient, who had previously been diagnosed with myelodysplastic syndrome 2 years ago, was admitted to our hospital for ESD of EGC. ESD was performed successfully in this patient after platelet concentrates transfusion on the day of ESD. ESD might be an option for the treatment of EGC in thrombocytopenia due to hematologic diseases when optimal supportive managements are applied.

We report here a case of inguinal sparganosis, initially regarded as myeloid sarcoma, diagnosed in a patient undergone allogeneic hematopoietic transplantation (HSCT). A 56-year-old male patient having myelodysplastic syndrome was treated with allogeneic HSCT after myeloablative conditioning regimen. At day 5 post-HSCT, the patient complained of a painless palpable mass on the left scrotum and inguinal area. Pelvic magnetic resonance imaging and computed tomography revealed suspected myeloid sarcoma. Gun-biopsy was performed, and the result revealed eosinophilic infiltrations without malignancy. Subsequent serologic IgG antibody test was positive for sparganum. Excisional biopsy as a therapeutic diagnosis was done, and the diagnosis of sparganosis was confirmed eventually. This is the first report of sparganosis after allogeneic HSCT mimicking myeloid sarcoma, giving a lesson that the physicians have to consider the possibility of sparganosis in this clinical situation and perform adequate diagnostic and therapeutic approaches.
