A Rare Case of a Retroperitoneal Abscess Due to Trichosporon spp. in an Immunocompetent Patient.

This report discusses a rare case of retroperitoneal infection caused by Trichosporon spp. in a 68-year-old immunocompetent woman following a nephrectomy. Trichosporon spp.  was identified through meticulous mycological examination. This case challenges the typical association of Trichosporon infections with immunocompromised patients, emphasizing its potential pathogenicity in immunocompetent individuals. The importance of accurate identification, especially in postoperative infections and broad-spectrum antibiotic contexts, is highlighted, emphasizing the need for a thorough diagnostic approach in such cases.
