Hip Arthroscopic Resection of an Intra-Articular Fibroma of the Tendon Sheath

Lucas Korcek et al. Case Rep Orthop. .

Abstract

Fibroma of the tendon sheath most often presents around small joints and involves the tendon and tendon sheaths of the fingers, hands, and wrist. In rare instances, it presents as an intra-articular mass. It has never been described in the hip joint. In the current case presentation, this benign tumor was found to be the source of a patient's atypical severe hip pain. Arthroscopic resection of this tumor alleviated the patient's pain.

(a) Low power histopathology view demonstrating one of the circumscribed nodules that comprised the multinodular tumor. Fibroblastic cells are spindled to stellate with variable cellularity set in a collagenous stroma. Slit-like capillaries can be seen as well (center to left). The right side of the image is the surface of the nodule (magnification 10x). (b) Tumor nodules had variable cellularity with hypocellular hyalinized appearing areas (top and left) alternating with regions with higher cellularity (right) (magnification 10x).
