Tracheal chondrosarcomas are rare, with only 14 cases previously documented. We report a case of chondrosarcoma of the trachea and review other published cases. Our patient was a 34-year-old man who began to feel shortness of breath 8 months after initial hemoptysis. Transverse and coronal computed tomography demonstrated a tumor that was obstructing nearly 80% of the tracheal lumen at the thoracic inlet. A bronchoscopic biopsy specimen led to an initial diagnosis of chondroma. Five tracheal rings from the third to the seventh including the tumor were completely resected, and an end-to-end anastomosis was performed. The histological diagnosis of the surgical specimen showed it to be a chondrosarcoma. The patient was alive without recurrence at 6 years 4 months after surgery. Because recurrence after incomplete resection and malignant transformation can occur with chondromas, radical resection of the trachea is recommended for all cartilaginous tumors of the trachea.

These data may explain that post-operative adjuvant chemotherapy with UFT was associated with improved survival in stage I patients with adenocarcinoma, but less with squamous cell carcinoma.

We report a rare case of sarcoidosis that developed during induction chemotherapy for primary lung cancer, mimicking progressive disease. A 63-year-old man had an abnormal shadow in the right upper lung, and a bronchoscopic examination revealed a squamous cell carcinoma. Swelling of a pretracheal lymph node was also noted. Thus, we gave induction chemotherapy consisting of paclitaxel (days 1, 8) + carboplatin (days 1, 8) for two cycles under clinical staging of T2N2M0. After induction chemotherapy, (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) showed positive accumulation of FDG in mediastinal and bilateral hilar lymph nodes that had been negative in a previous FDG-PET examination, which led us to suspect disease progression. Transbronchial lymph node biopsy results showed sarcoid granulomas in the specimens. Following complete resection of the lung cancer, sarcoid granulomas were revealed in both nonneoplastic lung tissue and lymph nodes, which resulted in a diagnosis of lung cancer accompanied with sarcoidosis.

Two middle-aged women developed retinal vasculitis in the moderately active phase of classical rheumatoid arthritis. Fluorescein angiography disclosed diffuse leakage from the retinal capillaries and cystoid macular edema, which subsided in response to oral steroid. They did not show any clinical signs of vasculitis in other parts of the body. Retinal vasculitis should be included in the list of complications observed in rheumatoid arthritis.
