A surgically-treated bronchopulmonary typical carcinoid tumor with ossification that invaded the bronchial wall

Background. Typical carcinoids are sometimes ossified, but rarely invade the bronchial wall. Case. A 29-year-old female showed an abnormal shadow on a chest X-ray, and CT revealed a nodule in the right lower lobe (S⁸, 25 x 23 mm). The tumor was well-defined, with irregular calcification. No metastatic lesions were observed. The serum adrenocorticotropic hormone (ACTH) level was elevated. We performed a right lower lobectomy and mediastinal lymph nodes dissection. The tumor was pathologically revealed to be a typical carcinoid without lymph node metastasis. The tumor invaded to the bronchial wall and was ossified. The patient has had no evidence of recurrence for 14 months postoperatively. The elevated serum ACTH was normalized after the surgery. Conclusion. We herein reported a case of a typical bronchopulmonary carcinoid tumor with ossification which invaded the bronchial wall. Carcinoids are sometimes recurrent and metastatic. Therefore, long-time postoperative follow-up is warranted.
