Spindle cell hemangioma of nasal passage and ethmoidal sinus in a 4-month old infant.

Spindle cell hemangioma (SCH) is a benign unusual vascular neoplasm. It does not have gender predilection and can occur at all ages. The disease affects dermis and subcutis of distal extremities predominantly; head and neck involvement is very rare, paranasal sinus involvement has not been reported before. Herein we present a 4-month-old infant with nasal obstruction since two weeks of age due to a mass in ethmoid sinus obliterating the nasal passage. After the histopathological diagnosis of SCH, the tumor was partially resected. In the sixth month follow-up, there was minimal regression of residual lesions. In the imaging studies performed 30 months after the surgery, the residual mass was found to be disappeared. SCH is not frequent in the head and neck, and presentation of some patients may not suggest the diagnosis. Histopathology is important for differential diagnosis and to orientate treatment. Awareness of SCH may increase the reported cases.
