Abstract:
A 64-year-old man presented with an asymptomatic left lower lobe mass. At bronchoscopy there was a tumor in the superior segment. Biopsy revealed an acinic cell carcinoma. There was no evidence of salivary gland or other site of origin. Lobectomy and lymph node staging showed involvement of interlobar (N1) nodes, while higher stations were benign. The patient remains well 20 months postoperatively. This is the only instance of primary pulmonary acinic cell carcinoma with lymph node metastasis among 15 cases in the literature. We review the clinical features, histology, and treatment of the reported cases.
