A Case of Subcutaneous Hemangioma Presenting as a Preauricular Sinus
A 44-year-old female came to our department with a 5-month history of intermittent right preauricular swelling and febrile sensation. She denied having had hearing loss, aural fullness, otaglia, tinnitus, and painful sensation. Her medical, surgical and family history were unremarkable. Upon physical examination, an ovoid shaped mass was softly palpable on 1 cm anterior from the tragus of right ear. The other findings of the head and neck were not significant but particularly, there was no pit around the softly palpable mass. Also, there was no secretion and painful sensation with pressure. Computed tomography (CT) demonstrated a 0.9 cm sized soft tissue mass in anterolateral to the right external auditory canal, which enhanced with contrast. The isolated mass was ovoid shaped and well-marginated without evidence of bony erosion of outer ear (). Based on the physical examination and computed tomography, preauricular fistula, salivary gland tumor, and enchondroma were possible diagnosis.\nUnder general anaesthesia, the mass was smoothly excised via the preauricular approach. The standard technique for preauricular sinus excision was used with a careful elliptical incision anterior to the crus and tragus on the superior portion of the mass and dissection without epithelial remnants. The size of the surgical specimen was 1.0×0.8 cm, reddish and soft (). Pathologic evaluation revealed well circumscribed, exophytic mass, delineated by squamous epithelium and proliferative small vessels (). On the basis of clinical examination and histopathology, a diagnosis of capillary haemangioma was concluded. The patient visited our clinic after a week with normal healing. She was also reviewed 1 and 3 months after surgical excision without the leision recurred.
