A Rare Cause of Hemoptysis in Childhood: Tracheal Capillary HemangiomaHemangiomas are benign tumors most frequently seen in childhood and are mostly associated with cutaneous and mucosal surfaces. Tracheal capillary hemangiomas are extremely rare. The most common presenting symptom is hemoptysis, ranging from minor to major and chronic cough. We present the case of a 12-year-old boy with recurrent hemoptysis due to tracheal capillary hemangioma, who was treated with interventional bronchoscopy.

INTRODUCTIONPrimary tumors of the trachea are extremely rare, with an estimated incidence of approximately 2.7 new cases per million per year, and usually malignant in adults [1]. Lobular capillary hemangioma (LCH) is a benign tumor, more commonly seen in children, with a distinctive lobular arrangement of capillaries in edematous and fibroblastic stroma [2]. The usual sites of tumor are the lips, nose, oral cavity, and tongue. It typically presents with nonspecific clinical symptoms, such as cough and hemoptysis. Stridor is observed with subglottic localization of the tumor. Radiologic studies and bronchoscopy are usually sufficient for diagnosis. Interventional bronchoscopic techniques can treat these lesions and avoid aggressive surgical approaches. Mills et al. [3] reviewed 639 cases of vascular lesions of the oral cavity and upper respiratory tract. They found only 73 cases with LCH and no case with localization in or below the larynx. There is very limited literature on tracheal LCH [1]. We present here the diagnosis and management of a rare case of tracheal LCH that was successfully treated with interventional bronchoscopy.
CASE PRESENTATIONA 12-year-old boy was admitted to our clinic due to recurrent hemoptysis. His symptoms started 2 years ago with approximately 100 mL of hemorrhage in a day after coughing. He also mentioned that a small amount of hemoptysis recurred whenever he had a respiratory tract infection. There was nothing in his history to indicate causes of hemoptysis, such as tuberculosis, recurrent lower respiratory tract infections, intravenous or oral drug use, or antibiotic therapy. He had no pets. Physical examination showed no abnormalities. His hematologic parameters were as follows: activated partial thromboplastin time: 24.7 sc; prothrombin time:15.2 s-58.2%, INR: 1.22; within normal limits). Other chemical laboratory test results were normal, as were chest radiography findings (Figure 1). Sputum acid-fast bacilli and Löwenstein-Jensen cultures were negative. Thorax computed tomography showed a polypoid lesion on the left lateral wall of the proximal trachea (Figure 2). Rigid bronchoscopy revealed a reddish polypoid lesion with a smooth surface on the left lateral wall localized in the proximal one-third of the trachea. The lesion was attached to the tracheal wall with a short pedicle (Figure 3a). The lesion was excised with electrocautery snare and was taken using biopsy forceps. The tracheal wall was coagulated with argon plasma coagulation...
