Subcutaneous Hemangioma on Nasal Dorsum Treated With Rhinoplasty: Literature Review

Vascular anomalies, including hemangiomas, which have slow blood flow, can develop anywhere on the body. They are mostly isolated lesions and are more common in women. The deformity does not regress on its own. A rare variety, known as subcutaneous hemangioma, grows aggressively and occasionally recurs after excision. In this report, we present a case of a 44-year-old female who experienced a slowly growing, painful nasal hump as a result of nasal trauma she sustained 7 years ago. She denied any associated symptoms apart from pain. Physical examination revealed a palpable, soft, nonmobile mass measuring ∼1 cm by 0.5 cm over the nasal dorsum. There was mild tenderness, and the skin appeared normal. Imaging workup with a CT scan showed a destructive process in the cortex of the left nasal bone, with soft-tissue density noted in the anterior left nasal cavity abutting the anterior nasal septum. Furthermore, an MRI study showed a well-defined, rounded, isointense lesion on T1 FSE images under the nasal bridge and hyperintense on T2 FSE images. Ultimately, the patient underwent open rhinoplasty. According to the histopathology results, there was reactive bone with skeletal muscle fibers, fibrosis, and dilated vascular channels. Atypia, mitosis, and necrosis were not present. The patient was doing well postoperatively with no complications and was scheduled for routine clinic follow-ups.
