A case of poorly differentiated hilar lung adenocarcinoma of an unidentified histological type.
The patient was a 74-year-old man, a physician, whose chief complaint was an unproductive cough. The shadow of a mass was seen at the hilum of the left lung, and the mediastinal lymph nodes on both sides were swollen. No histological diagnosis was obtained even after bronchoscopy, including transbronchial needle aspiration biopsy, but large-cell carcinoma of the lung was diagnosed on the basis of ultrasound-guided biopsy of a shadow in the liver suspected of being a metastatic tumor (T2N3M1, Stage IV). Two courses of chemotherapy (CBCDA + VDS) failed to gain any improvement, and the pain resulting from recurrent bone metastases was managed mainly by the administration of the best supportive care. The patient was readmitted to the hospital after development of numbness in the right upper extremity followed by complication of pneumonia and heart failure, and he passed away. Autopsy revealed a primary hilar lung tumor with a histological diagnosis of poorly differentiated adenocarcinoma.
