esophageal squamous cell carcinoma
It is rare that small cell carcinoma has multiple polypoid lesions. There is few report of small cell carcinoma in trachea and bronchus. We experienced a case of multiple polypoid lesions of small cell carcinoma.
In January ２０１X, Woman in ６０s had operation for esophageal squamous cell carcinoma. In July ２０１X, thoracic and abdominal CT for postoperative follow-up revealed many nodules in the trachea, the bronchus, the lungs, and the liver, and mediastinum lymphadenopathy. We examined bronchoscopy and there were multiple polypoid lesions in the trachea and bronchus. Left main bronchus were almost occluded by maximum lesion, and we performed biopsy. We suspected recurrence of esophageal squamous cell carcinoma, therefore quickly started chemotherapy（CDDP＋５‐FU）and radiation for the left main bronchus. However, the pathological diagnosis was small cell carcinoma, we stopped the chemotherapy for esophageal squamous cell carcinoma.
This case suggests we should examine to differentiate primary tumor or metastasis when we find a new lesion.
