Multiple Pyogenic Granulomas in the External Auditory Canal

Abstract

Pyogenic granuloma is a benign vascular tumor of the skin or mucous membrane. One-third of pyogenic granulomas have been reported in the head and neck, but it is rarely present in the external auditory canal. Pyogenic granuloma mostly presents as a solitary granuloma, and only a few cases of multiple forms have been reported. This report describes a rare case of multiple pyogenic granulomas in the external auditory canal of a 36-year-old man along with a review of the literatures. Although it is very rare for PGs to occur in the EAC, it can be suspected in conditions such as after acute and/or chronic trauma, hormonal changes or systemic drug administration, rapid growth, and easy bleeding tendency with a friable surface. Some PGs may spontaneously resolve, but when they cause symptoms, excision is recommended for treatment and diagnosis. In the case of excision, the tumor should be excised down to the perichondrium level to prevent recurrence. Although PG mainly occurs in a solitary form, the present case shows a new clinical variation where multiple PGs were present in the EAC.
