[Chondromatous hamartoma of the lung with a unique demonstration on diagnostic imaging; report of a case].
A case of pulmonary hamartoma is reported with clinical, roentgenographical and histopathologic findings. The patient was a 53-year-old woman who had undergone right hemithyroidectomy for thyroid cancer 4 years before. An abnormal shadow, which was a non-clearly demarcated tumor, 2 cm in diameter, in the left middle lung field, was noted on her routine X-ray in February 2001. Physical examination and laboratory data revealed no significant findings, but computed tomography(CT) scans of the chest showed a gathering of small-sized high-density lesions in the nodule. She underwent left S8 segmentectomy on March 21, 2001. The pathology report on the frozen section was pulmonary hamartoma. Histopathologically, the lesion was characterized by a composition of bronchial epithelium, fat tissue and cartilage, with being diagnosed as a chondromatous hamartoma of the lung. The patient's postoperative course was uneventful, and she was discharged with no supportive therapy 14 days after the operation. To date, 14 months after the operation, the patient has been in good condition, without evidence of recurrence or distant metastasis on diagnostic imaging. This case is particularly interesting because a gathering of small-sized pulmonary hamartoma was demonstrated by imaging.
