[Pulmonary metastasis fifteen years after hysterectomy for uterine leiomyosarcoma; report of a case].

A 75-year-old woman who had undergone a hysterectomy for uterine leiomyosarcoma 15 years before was noted to have a lung tumor on chest radiography. Chest computed tomography (CT) showed a tumor mass, 3.5 cm in size, in her left lung (S10). CT-needle aspiration biopsy revealed sarcoma We performed a left lower lobectomy, as there was no distant metastasis. The histopathological diagnosis was a metastasis of uterine leiomyosarcoma. The disease-free interval for this case was 15 years, which was. to our knowledge, the longest among previous reports of pulmonary metastasis of uterine leiomyosarcoma.
