Small-sized peripheral squamous cell lung carcinoma with chest wall invasion

Abstract

In lung cancer, chest wall infiltration caused by a tumor with a small diameter is extremely rare. The pathophysiologic features and prognosis of this phenomenon are poorly understood. Here, we report on a case in which a small peripheral lung cancer showed marked invasion into the chest wall. Although complete resection and postoperative adjuvant treatment were performed, lymph node recurrence developed and the patient died in one and a half years. Peripheral lung cancer can show exophytic development and infiltration of the chest wall, leading to poor prognosis, even if the tumor size is relatively small.
