Abstract
Primary endobronchial leiomyosarcoma is a very uncommon tumor and its diagnosis by spontaneous expectoration of tumor fragment has never been reported in the literature. We report a patient with primary endobronchial leiomyosarcoma that was diagnosed by spontaneous expectoration of partial tumor tissue. The expectorated tissue was found to be pathologically consistent with leiomyosarcoma. Right lower lobectomy and all lymph node dissections were performed during the operation. Pathologic examination showed that the tumor was histologically identical to the patient's previous expectorated tissue and was confined to the bronchus and did not invade the adjacent pulmonary parenchyma and lymph nodes.
원발성 기관지 평활근육종은 매우 드문 종양으로서, 종양 조직의 객담 배출에 의해 진단된 보고는 아직 없다. 저자들은 종양 조직의 객담 배출에 의해 진단된 원발성 기관지 평활근육종 환자를 보고하고자 한다. 객담으로 배출된 종양 조직은 병리학적으로 평활근육종으로 진단되었으며, 우측 하엽 절제술과 임파절 절제술을 시행하였다. 절제된 종양의 병리조직 소견은 이전에 객담으로 배출된 종양의 조직 소견과 동일하였고 기관지내에 국한되어 있으면서 주위 폐 조직이나 임파절은 침범하지 않았다.
