Primary high-grade diffuse large B-cell lymphoma of the glans penis.

Diffuse large B-cell lymphoma (DLBCL) of the penis is a rare haematological malignancy, with less than 30 cases being reported in the literature. Our case mentions a 57-year-old man who presented with a penile lesion that was diagnosed as DLBCL on histological biopsy. Targeted investigation and proper diagnosis are essential to distinguish it from squamous cell carcinoma (SCC) of the glans, which presents similarly. Since guidelines are not available, the author compared different management mentioned in case reports and the outcome was noted. Chemotherapy, radiotherapy and surgery were the treatment modalities most used; out of which, chemotherapy had the most successful outcome. On the other hand, surgery is the preferred modality in SCC of the penis. This further consolidates the need for guidelines with regard to proper diagnosis and management of this malignancy.
