Concurrence of malignant fibrohistiocytoma and Takayasu arteritis: a case report

Takayasu arteritis (TA) is a type of systemic large-vessel vasculitis that usually affects the aorta and its major branches. It remains unrecognized owing to delayed diagnosis (Boltin et al. in Rheumatol Int 27(10):985–987, 2007) and non-characteristic clinical features. It has been described in association with many autoimmune diseases, such as inflammatory digestive tract diseases. However, report of TA associated with tumors, especially malignant tumors, are rare. We here presented a case diagnosed by both Takayasu arteritis and malignant fibrous histiocytoma, from which we learned not only clinical lessons, but also consensus of relationships between these two diseases.
