Giant cell tumor of the tendon sheath mimicking a plexiform neurofibroma

Abstract

Giant-cell tumor of the tendon sheath (GCTTS) is a benign soft tissue tumor of the limbs arising from the complex of the tendon sheath and periarticular soft tissues of small joints. It is the second most common benign space occupying lesion in the hand and usually presents as a painless soft tissue mass, which grows slowly in size for many years. We present an interesting case of an enormous GCTTS presenting as a slowly growing mass over left sole of a 52-year-old woman. The duration of GCTTS may range from a few weeks to 30 years but in our case the duration of tumor was almost 48 years, which could be the longest reported duration of GCTTS.

Giant cell tumor of tendon sheath: A report of 216 cases

“…The mass diameter was 0.2–3.0 cm. The most common sites are hand region 44.4%, knee 16.2%, foot 14.8%, ankle 11.6%, wrist 5.6%, leg 5.6%, head 0.9%, forearm 0.5%, and inside and outside the spinal channel 0.5%, which is highly consistent with previous literature reports 33–35 …”

“…The most common sites are hand region 44.4%, knee 16.2%, foot 14.8%, ankle 11.6%, wrist 5.6%, leg 5.6%, head 0.9%, forearm 0.5%, and inside and outside the spinal channel 0.5%, which is highly consistent with previous literature reports. [33][34][35] GCTTS is clinically nonspecific and presents as a superficial, slowgrowing, hard and painless mass. According to gender, age, and clinical palpation of the patient's mass, ultrasound, x-ray, magnetic resonance imaging, computerized tomography (CT), and other examinations should be combined if necessary.…”

Locally Invasive Pigmented Villonodular Synovitis of the Wrist Treated by Arthroscopic Resection and Bone Grafting

“…The usual location of these tumors tends to be in the hands primarily in the tendon sheaths of the index finger predominantly, followed by the middle finger and then the thumb 7,8,10 . Previous studies report on average a 5.6% incidence in the wrist joint 11–13 . In our patient it was in an unusual location of the radiocarpal joint with marked erosion into the scaphoid.…”

“…7,8,10 Previous studies report on average a 5.6% incidence in the wrist joint. [11][12][13] In our patient it was in an unusual location of the radiocarpal joint with marked erosion into the scaphoid. Although benign, it is locally aggressive with a high recurrence rate (7%-44%).…”
