title: Pulmonary leiomyomas in a patient with bilateral renal cell cancer mimicking pulmonary metastases.
abstract: Pulmonary benign metastasizing leiomyoma (PBML) characterized by uterine leiomyoma in the lung is very rare. Here we report the case of a 55-year-old woman with a history of surgically resected multiple uterine leiomyomas who was histopathologically diagnosed with PBML associated with bilateral primary renal cell carcinoma (RCC). Clinicians should be aware of this unusual entity and consider pulmonary leiomyoma as a differential diagnosis in asymptomatic women with primary RCC and a history of hysterectomy for leiomyoma.
