Primary renal lymphoma in patient of tinea incognito: Rare clinical entity

A middle aged male patient, suffering from tinea incognito for 3 months along with history of significant weight loss for last 2 months, was admitted for hematuria in emergency ward. He was subsequently diagnosed with left renal mass. Computed tomography scan of abdomen showed a large lobulated density mass in lower pole of left kidney, over circling the left pelviureteric junction causing hydronephrosis and no hepatosplenomegaly. There was no evidence of retroperitoneal lymphadenopathy, peritoneal nodules, or ascites. Clinically suspecting renal cell carcinoma, the patient declined radical left-sided nephrectomy as the primary choice of treatment. Tru-cut renal biopsy revealed diffuse large Bcell non-Hodgkin′s lymphoma. Following six cycles of chemotherapy along with antifungal medications, both tinea lesions and renal mass were cured.
