Tracheopathia osteoplastica is an unusual disease characterized by cartilaginous or bony projections into the tracheobronchial lumen, with sparing of the posterior membranous portion of the tracheobronchial tree. The cause of this disorder is unknown. The diagnosis is seldom made because of the chronic and asymptomatic nature of the condition. More than 90% of the cases are diagnosed at postmortem examination. Symptoms may include dyspnea, coughing, hemoptysis, hoarseness, and wheezing. Tomography of the trachea may reveal beaded calcification of the tracheobronchial cartilages. Bronchoscopy is diagnostic. Histologically, the abnormal growths show heterotopic bone formation. No known treatment is available. We describe two female patients, one with hemoptysis and another with asthmalike symptoms, in both of whom bronchoscopy established the diagnosis of tracheopathia osteoplastica. The first patient had recurrent episodes of pneumonia attributable to bronchial obstruction by bony projections. In the second patient, removal of large lesions that obstructed the upper part of the trachea relieved the dyspnea. Of interest is the fact that the first patient was the biologic mother of the second. To our knowledge, this constitutes the first report of familial occurrence of tracheopathia osteoplastica.

Tracheopathia osteochondroplastica (TPO) is a rare, but increasingly recognised condition in which there is accumulation of calcium phosphate with benign submucous proliferation of cartilage and bone beneath the tracheal mucosa, often with squamous metaplasia of the mucosal columnar epithelium. This condition is usually asymptomatic, but may be slowly progressive, causing haemoptysis, dry cough and dyspnoea. We report a case of TPO in which there was rapid progression of tracheal stenosis such that the size of endotracheal tube that the upper airway would accept changed from 8.00 mm to 3.0 mm during a six-week period. This extreme reduction in airway calibre had not been detected on spirometry nine days prior to his final admission. This is the first report of such rapid progression of tracheal stenosis associated with TPO.

The case of a male, 61 years of age, presenting with occasional hemoptysis and shortness of breath (duration of 1 year) is reported. Congestive heart failure was presumed and supported by chest x-ray and echocardiography. The patient improved with diuretic and angiotensin converting enzyme (ACE) inhibitor therapy, but continued to experience cough and occasional hemoptysis. Bronchoscopy revealed numerous firm nodular projections within the trachea with distribution along the cartilaginous rings. Tracheopathia osteochondroplastica (TPO) was diagnosed. TPO is an uncommon, benign, but slowly progressive disease of unknown etiology. It is characterized by endoluminal projection of cartilaginous and bony nodules arising in the submucosa of the trachea. Involvement may extend to lobar or segmental bronchi. TPO should be considered in cases where cough, dyspnea, persistent pulmonary infection, hoarseness, or recurrent hemoptysis remain after appropriate treatment of other presumptive underlying causes.

Tracheopathia osteoplastica (TPO) is a rare disorder characterized by cartilaginous or bony mucosal nodules in the tracheobronchial tree. Due to most patients being asymptomatic, the majority are diagnosed post-mortem. If symptoms are present, they typically include chronic cough, dyspnea, hemoptysis, hoarseness, and wheezing, with some of these symptoms overlapping with asthma. This case report describes an adult female with chronic cough who was diagnosed with asthma that was refractory to therapy for 8 years. Computed tomography (CT) of the chest revealed several soft tissue masses in the trachea with bronchoscopy revealing TPO in the upper portion of the trachea. She was diagnosed with TPO and started on airway clearance and a nasal corticosteroid spray with resolution of the cough at follow-up 3 months later.
