The association of bladder myeloid sarcoma and unclassified myelodysplastic/myeloproliferative disease.
Myeloid sarcoma of urinary bladder is a rare disorder. We report a 71-year old man with hematuria. He was also under follow up for unclassified myeloproliferative/ myelodysplastic disorder, diagnosed 2 months ago. Abdominal ultrasonography and computed tomography findings were normal. Diagnostic cystoscopy revealed patchy areas of mucosal swelling with hyperemia. Histopathological examination of biopsies demonstrated a neoplasm composed of blasts showing myeloperoxidease positivity by immunohistochemistry. To our knowledge, current case is the first case of myeloid sarcoma without evidence of a mass lesion in the urinary bladder with a concurrent diagnosis of myelodysplastic /myeloproliferative disease, unclassifiable.
