Prostatic Abscesses in a Patient Receiving Tumor Necrosis Factor-Alpha Inhibitor Therapy for Hidradenitis Suppurativa: A Case Report.

This report is the first to present the case of a patient who developed bacterial abscess-forming prostatitis while undergoing treatment with adalimumab, a tumor necrosis factor-alpha blocking therapy, for hidradenitis suppurativa. A 36-year-old male presented with persistent anogenital pain and dysuria for approximately three weeks. Two days before presentation at the emergency room (ER), a rubber band ligation was performed to address suspected hemorrhoids stages I-II. In the ER, clinical and laboratory examinations suggested acute prostatitis, prompting the initiation of antibiotic therapy. In the absence of an adequate response, magnetic resonance imaging was performed, which identified a complex abscess and fistulation system originating from the right prostatic lobe. Following the insertion of a drain, adalimumab was discontinued, and antibiotic therapy was intensified, resulting in the resolution of the abscess. After six weeks, follow-up showed the patient to be free of symptoms. This case highlights a rare adverse event of patients using immunomodulating medications and may help physicians to manage similar cases in the future. Immunomodulating drugs can lead to the development of prostatic abscesses in young patients, necessitating attentive and careful clinical examination with a low threshold for further diagnostic workup in uncommon case presentations.
