Unusual Histology in Hodgkin’s Lymphoma: Report of an Interesting Case
Tóm tắt
Hodgkin’s lymphoma has a significant presence in the Indian subcontinent. Microscopically, the hallmark of Hodgkin’s lymphoma (HL) is the Hodgkin and Reed-Sternberg (HRS) cell, which is usually surrounded by a cellular infiltrate of non-malignant inflammatory cells that constitute the majority of the tumor tissue. Cells which are known to be histologic mimics of HRS cells include immunoblasts, plasmablasts and rarely dendritic cells. We report a case of a 70-year-old male who presented with fever and lymphadenopathy. In the present case, the large cells with prominent nucleoli stained positively for both CD15 and CD30 and hence the possibility of angioimmunoblastic lymphadenopathy which was considered on the H&E-stained sections was excluded. In addition, noteworthy microscopic features in this case were angiogenesis and the presence of mast cells, both associated with a poor prognosis. The clinical impression was that of disseminated tuberculosis, but on histopathology, the final opinion was ‘Hodgkin’s lymphoma not classifiable with an unusual histology’. The aim of reporting this case is to highlight the unusual presentation in the form of prominent angiogenesis and mast cell infiltration in a case of HL, which is indicative of a poor prognosis.
