The imaging and pathological features of a mucinous tubular and spindle cell carcinoma of the kidney: a case report

A mucinous tubular and spindle cell carcinoma (MTSCC) is a rare and recently described kidney neoplasm with distal nephron differentiation. It can affect patients of all ages and is more prevalent among women. In this case report, we present a 50-year-old woman who had a renal mass, which was accidently discovered during an investigation for chronic anemia. The final diagnosis of MTSCC was made after the lesion was removed and a pathology work-up was performed. The clinical, pathological and imaging findings of this rare neoplasm are described in this report.

We are grateful to Larissa VF Landgraf, a medical resident at the Department of Pathology, Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, for performing the gross examination of the case.
