Diffuse Large B-Cell Lymphoma of the Trachea in a Child With Symptoms of Bronchial Asthma.

Tracheal tumors are rare in children and manifest symptoms of airway obstruction. A 14-year-old boy with a 5-month history of dyspnea and wheezing was referred to our hospital. Although he had been initially diagnosed with bronchial asthma, computed tomography revealed tracheal tumors. Histologic examination showed only necrotic tissue. Thereafter, the systemic steroid treatment for bronchial asthma was tapered off. A second computed tomography scan revealed new lesions in the pancreas and lung. Biopsy of the pancreatic lesion revealed a diffuse large B-cell lymphoma. The patient was administered standard chemotherapy, following which he went into complete remission.
