Primary penile lymphomas are extremely rare. They are aggressive neoplasms that can present as double-or triple-hit lymphomas, and because the associate with a high risk of central nervous system dissemination, treatment consists of high-dose chemotherapy regimens plus intrathecal prophylaxis. Pathology can be confused with squamous cell carcinoma of the penis, leading to inappropriate treatments and unnecessary amputations. We report the case of a patient diagnosed with clinical Stage IV penile non-Hodgkin lymphoma that was treated with a complete and durable response. In addition, we review the available literature on penile lymphoma.

Background: Neurogenic erectile dysfunction, characterized by neurological repair disorders and progressive corpus cavernosum fibrosis (CCF), is an unbearable disease with limited treatment success. IL-17A exhibits a complex role in tissue remodelling. Nevertheless, the precise role and underlying mechanisms of IL-17A in CCF under denervation remain unclear.

- Diffuse large B-cell lymphoma (DLBCL) is a type of aggressive cancer that usually affects lymph nodes but can also spread to other organs, with penile metastasis being very rare.
- A 79-year-old man with a history of DLBCL experienced remission after chemotherapy, but eight months later developed a penile mass that turned out to be recurrent DLBCL.
- This case highlights the need to consider unusual metastasis sites in DLBCL patients and the importance of thorough diagnostic evaluations to improve early detection and treatment outcomes.
Cancer risk among people living with Human Immunodeficiency Virus (HIV) in Rwanda from 2007 to 2018.

Assessing the risk of cancer among people living with HIV (PLHIV) in the current era of antiretroviral therapy (ART) is crucial, given their increased susceptibility to many types of cancer and prolonged survival due to ART exposure. Our study aims to compare the association between HIV infection and specific cancer sites in Rwanda. Population-based cancer registry data were used to identify cancer cases in both PLHIV and HIV-negative persons.

Article Synopsis
- Primary testicular lymphoma (PTL) is rare, and patients often receive radiation therapy to the contralateral testis to prevent relapse after achieving remission.
- A 76-year-old man treated for PTL developed a new mass in the glans penis 6.5 years later, prompting investigation into whether it was a relapse or a new cancer.
- Genomic analysis revealed that the penile lymphoma shared genetic similarities with the original PTL, confirming it as a relapse, marking it as the first reported case of PTL returning in the glans penis.
