title: A case of subcutaneous hemangioma presenting as a preauricular sinus.
abstract: Hemangioma is one of the most common benign neoplasm involved on head and neck. However, cavernous hemangiomas are relatively rare in preauricular sinus space and has rarely been reported around the world. Recently, a 44-year-old female patient came to our clinic with cavernous hemangioma involving the preauricular sinus. This case was surgically managed via excision. Preoperatively, it was difficult to differentiate the mass of hemangioma clinically and diagnostically from a preauricular fistula, a salivary gland tumor, or an enchondroma. This case report describes the subcutaneous hemangioma on a preauricular sinus, which is rarely seen in Korea. The clinical presentation and management are discussed with a review of the literature.
