Objective:
To summarize the characteristics of pathogenesis, image, treatment and prognosis of pulmonary hamartoma.
Methods:
39 cases with hamartoma confirmed by pathology received surgical operation during 1971-1998 period. Their clinical data including symptoms, disease courses, image characteristics and surgery types were investigated. The prognostic results of 31 cases were collected by a follow-up study.
Results:
The average age of morbidity was 44 years old and the mean disease course of hamartoma was 13 months. 21 cases without symptoms were determinated by chance and 18 cases with some extent of cough, expectoration, fever, chest distress, and short of breath. The hamartomas of 21 cases were in right lung, 18 in the left. Image characteristics presented as popcom-shaped tumor with clear border and without satellite focus. 31 cases underwent enucleation, 4 wedge-shaped resection, 3 lobectomy and 1 pneumonectomy. No recurrence or malignant change was demonstrated by follow-up study.
Conclusions:
Pulmonary hamartoma is a kind of neoplasms with satisfactory prognosis. Intraluminal hamartoma should be differentiated from hilar lung cancer. Localized resection should be performed for the treatment of the disease.
