Renal myxoma: an unexpected differential diagnosis.

Myxomas are rare mesenchymal tumors that can appear in many anatomical locations, although they are mainly seen in heart and skin. To date, only twelve cases of pure renal myxomas have been reported in the literature. We describe a case of a young Cuban woman with an asymptomatic irregular cyst lesion in her left kidney which was eventually diagnosed as renal myxoma. We also provide radiological and pathological studies.
