Plasmablastic lymphoma with cutaneous manifestations in an immunocompetent man: A rare case report with literature review.

Plasmablastic lymphoma (PBL) is an aggressive lymphoma and is regarded as a subtype of diffuse large B-cell lymphoma (DLBCL). It is generally found in immunosuppressed and transplanted individuals, but very less often in immunocompetent individuals. It shows positivity for Epstein-Barr virus (EBV) infection in 60% of cases. Few cases have been seen in immunocompetent patients, but rarely as cutaneous manifestations. In the recent past, very few studies have discussed the cytological features of PBL. Due to its rarity, diagnosis and management of this unique entity pose a challenge. Moreover, it is also important to differentiate this entity from other close mimics, especially PBL, which morphologically resembles PBL. We hereby present a rare case of aggressive PBL, presenting with multiple cutaneous manifestations, initially diagnosed on aspiration cytology.
