Fournier's gangrene developing secondary to infected hydrocele: A unique clinical scenario

We report the first case of Fournier's gangrene (FG) developing secondary to an infected hydrocele worldwide. We present a case report with a brief overview of the literature relating to FG and its aetiology, diagnosis and management. A 70 year-old male was referred by his General Practitioner with a 2 week history of worsening symptoms of scrotal discomfort and swelling. Following clinical examination, an initial diagnosis of an infected right-sided hydrocele was made and treatment, consisting of antibiotics, was initiated. Despite showing good clinical improvement, several days later, necrotic areas were observed over the right hemiscrotum with spreading cellulitis. A diagnosis of FG was made. The patient was started on triple-therapy antibiotics and taken to the operating room for urgent surgical debridement. Necrotic skin and subcutaneous tissue extending over the perineum and lower anterior abdomen was debrided down to healthy tissue. A further debridement took place 2 days later. The patient continued to improve and was eventually discharged under the care of Plastic Surgeons for reconstruction of the soft tissue defect. FG is a type of necrotising fasciitis predominantly affecting the male perineal, perianal, genital and anterior abdominal wall regions. It has a significant mortality rate, and the key to survival is early detection and treatment consisting of antibiotics and surgical debridement of the affected area. To the best of our knowledge, this is the first reported case of FG developing secondary to an existing hydrocele without any prior urological intervention. The case highlights the important clinical diagnostic and therapeutic interventions required to prevent complications associated with this, potentially fatal, condition.
