Osteochondroplastic tracheobronchopathy: Four case reports

Osteochondroplastic tracheobronchopathy is a rare benign chronic disease of unknown etiology. Bronchoscopy remains the gold standard for diagnosing osteochondroplastic tracheobronchopathy. Its typical findings are described as a cobblestone, rock garden, mountainscape, or stalactite cave appearance. The present work aims to show the main clinical features of this rare pathology.

The clinical data of four middle-aged patients, three men and one woman, were analyzed. The main clinical symptoms were chronic cough, dyspnea, and dysphonia. The patient's preliminary diagnosis was made by computed axial tomography of the chest, confirmed by bronchoscopy and histopathological examination. Treatment included medication for symptoms and, in one case, cryosurgery and argon plasma coagulation.

Diagnosing osteochondroplastic tracheobronchopathy was not easy, given its uncommon nature and non-specific symptoms often found in other pathologies. No case series articles on this pathology have been published in Peru. Therefore, we used the original articles published in other countries to reference our findings.

Osteochondroplastic tracheopathy is a benign disease that typically affects adults. Men are more likely to be affected. Its clinical manifestations are non-specific and frequently of pharyngeal origin, and the cause is not yet defined. Chest computed axial tomography combined with bronchoscopy are the main diagnostic procedures. There is no standard treatment with consistent therapeutic effects.
