Desmoid Tumor Causing Hip Joint Contracture: A Case Report

Desmoid tumor (DT) is a relatively uncommon, cytologically bland fibrous neoplasm that is associated with possibility of local recurrence but without the potential to spread to other parts of the body. This disease affects mostly younger adults and is the most common cause of abdominal wall masses in women 20 - 35 years of age. However, it may involve nearly every body part, including the extremities, head and neck, trunk, and abdominal cavity; as such, patients with DT may present to a range of general and subspecialty radiologists. The consensus for treatment has changed over the past decade, with most centers moving away from primary radical surgery towards a front-line “wait-and-see” policy. Here, we present a case of a tumor mass that induced hip joint contracture. DT does not usually cause functional disorder. Oncologists should be aware that a desmoid tumor can cause hip joint contracture if the mass occurs in the gluteal region. Moreover, DT resulting in such a functional disorder should be treated by resection.
