Mucinous, Tubular and Spindle Cell Carcinoma of the Kidney: a Case Report and Literature Review
Year: 2025
Type: article
Study design: Case Report
Abstract: INTRODUCTION: Mucinous, tubular and spindle cell renal carcinoma is an epithelial neoplasm which makes up less than 1% of all renal neoplasms. It is most common in the renal cortex and is characterized by tubules which merge with soft spindle cells in a myxoid stroma. Usually, it is an asymptomatic tumor diagnosed incidentally in imaging exams. CASE DESCRIPTION: A 67-year-old male patient was attended at a university hospital with diffuse abdominal pain. A computed tomography scan showed a renal mass of approximately 9 cm in its largest dimension. He underwent a nephrectomy, and the histopathological analysis was compatible with mucinous, tubular and spindle cell renal carcinoma. CONCLUSION: Mucinous tubular and spindle cell carcinoma is a rare neoplasm, with nonspecific findings and, therefore, of a difficult diagnosis. The absence of a spindle component and genetic analysis may help in differential diagnosis, essential to determining the correct prognosis and patient follow-up.
