Narrow resection of cutaneous melanoma

We report the case of a young pregnant woman with a malignant tumour of the kidney suggestive of oncocytoma. Because of the pregnancy, preoperative staging consisted of abdominal ultrasound and magnetic resonance imaging. Caesarean section was performed. Several days later, surgical exploration of the kidney was performed with tumourectomy and frozen section analysis: radical nephrectomy was finally performed. The definitive histology was chromophobe renal cell carcinoma. This is a rare tumour of the kidney, with its own characteristics allowing histopathological diagnosis and with a better prognosis than renal cell carcinoma. In the literature, pregnancy, a situation of immune depression, does not increase the prevalence of malignant neoplasms.
