Abstract
The spontaneous regression (SR) of cancer is defined as the complete disappearance of a malignant disease without
adequate treatment. SR is a very rare biological event, particularly in a pulmonary sarcoma. We report the first
documented case of an endobronchial sarcoma that regressed spontaneously in Korea.
We encountered a rare case of a 72-year-old woman with an undiagnosed intrapelvic cystic mass, who presented with
a smooth surfaced endobronchial tumor obstructing the orifice of the right lower lobe bronchus on a bronchoscopic
examination. She had a prior history cervical cancer and adenocarcinoma in the right middle lobe lateral segment of
her lung for which she had undergone radiation therapy. The tumor was diagnosed as an endobronchial sarcoma by
the histopathology findings and immunohistochemistry. It was unclear if the tumor was a primary sarcoma of the lung
or a metastatic lesion of an intrapelvic cystic mass because she refused a diagnostic exploratory laparotomy. Two months
later, obstructive pneumonia of the right lower lobe with parapneumonic effusion developed with fever above 38.5℃ for
10 days. After recovering from pneumonia, she was followed up regularly in the outpatient clinic without any specific
treatment. One year later after treating the obstructive pneumonia, the follow-up bronchoscopy revealed complete SR
of endobronchial sarcoma. It is believed that the obstructive pneumonia accompanied by fever above 38.5℃ for 10 days
might have played a role in this SR. (Tuberc Respir Dis 2007; 63: 94-99)
Key Words: Spontaneous regression, Endobronchial sarcoma, Pneumonia.

직 정확히 규명된 기전은 없으며 최소한 한 가지 이상
