구인두 후벽의 소엽성 모세관 혈관종 1예

Lobular capillary hemangioma or pyogenic granuloma is a benign acquired tumor microscopically composed of small blood vessels arranged in lobular pattern. This rapid growing, polypoid, friable and hemorrhagic mass usually involves the skin and mucosa of oral cavity. However, except for the oral cavity, this lesion is very rare in aerodigestive tract. Recently, we have experienced a lobular capillary hemangioma originated on posterior oropharyngeal wall which was mistaken for a secondary oropharyngeal tuberculosis. A 34-year-old male who has been diagnosed as pulmonary tuberculosis presented a pharyngeal mass associated with swallowing difficulty, for which surgical excision with bipolar electrocautery was performed. Histopathologic findings led to the diagnosis of a lobular capillary hemangioma, which arised from posterior oropharyngeal wall. There was no complication or evidence of recurrence after 6 months from the operation. We report this case with a review of literature. (J Clinical Otolaryngol 2008;19:243-246)
