Retroauricular intravascular lobular capillary haemangioma in a child

Summary 

Lobular capillary haemangioma, formerly pyogenic granuloma, has an unclear etiopathogenesis and rarely occurs in an intravascular location.

A 9-year-male with a right retroauricular mass that was clinically mistaken for a typical dermoid but appeared unusually vascular at excision was finally diagnosed as an intravascular lobular capillary haemangioma arising in a haemangioma (composite haemangioma). The histolopathologic features of lobules of capillaries in a loose oedematous fibromyxoid stroma and “glomerulations” confirmed the diagnosis. At 2 years after excision, there is no recurrence and he is asymptomatic.
