We present a rare case of clear cell adenocarcinoma of the male bulbomembranous urethra. Mostly these tumors have been described in the female urethral tract with its possible origin from mullerian remnants, wolffian remnants or paraurethral glands. Histologically, these tumors have typically tubulocystic pattern comprising of hobnailed cells with clear glycogenated cytoplasm along with well-defined cytoplasmic membranes. This case is being presented due to its rarity, aggressive behavior and to discuss, trauma as its possible etiological factor.
Mixed phenotypic acute leukemia (MPAL) is a rare disorder with an incidence of less than 2% of all acute leukemia using the recent 2008 WHO criteria. Common subtypes encountered are the B/myeloid and T/myeloid; B/T or trilineage MPAL being an exception. We discuss here a case of 20-year-male patient who presented with pallor and generalised lymphadenopathy. Peripheral blood smear examination showed presence of 61% blasts of lymphoid morphology. Immunophenotyping by multicolor flow cytometry showed two distinct populations of blasts with T and B phenotype respectively. He was diagnosed as MPAL with two distinct blast lineages. Conventional karyotyping done on bone marrow sample showed t(9;22)(q34;q11)(Ph 1). Induction was started using ALL based protocol. The patient is on follow up with post induction marrow being in morphological remission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
