Scrotal Malakoplakia in a Post-Lung Transplant Patient: A Case Report.

Malakoplakia is a rare granulomatous disease characterized histologically by Michaelis-Gutmann bodies and sheets of macrophages with granular eosinophilic cytoplasm. While it most commonly affects the genitourinary tract, it can manifest in various locations, including cutaneous sites. This report details a rare example of scrotal malakoplakia in an 82-year-old man with a history of idiopathic pulmonary fibrosis, developing 7 months post-lung transplant, during ongoing chronic immunosuppressive therapy. Histopathological examination confirmed the diagnosis. This report highlights the importance of considering malakoplakia in the differential diagnosis of scrotal lesions, particularly in immunocompromised patients where the clinical presentation may be atypical.
