The giant cell tumour of the tendon sheath (GCTTS) is the second most common soft tissue benign tumour and rarely presents in the knee. We report a rare presentation of a GCTTS in the knee with corresponding magnetic resonance imaging (MRI), an arthroscopic picture, and histological presentation. It is a rare occurrence but should be considered as a differential in atraumatic knee pain presenta...

Recent studies suggest that Denosumab reduces tumor size, therefore, makes the surgery easier with lowermorbidity. However, some studies have reported several complications for this drug. So, this systematic reviewwas performed to determine the effectiveness and safety of Denosumab in reducing bone destructions activity ofgiant cell tumor and skeletal-related events (SRE) in affected patients w...

Chondroma of soft tissue is rare. We report a patient in whom a chondroma occurred within the flexor tendon sheath of the index finger. Magnetic resonance imaging showed the extent of the tumor, which wrapped around flexor tendons within the sheath, but did not invade either tendons or sheath. Total excision was done with preservation of the flexors and flexor tendon sheath. After the operation...

Haemangiomas developing in the hand in relation to tendon and the tenosynovium (tendon sheath) are very rare. To our knowledge only three cases have been described arising in relation to the tenosynovium of the tendons of the hand, only one of which showed infiltration of the underlying tendon. We report the case of a 16-year-old right hand dominant student who presented to her family doctor wi...

Tenosynovial giant cell tumour (localized type) is a tumour of tendon sheaths and interphalangeal joints, affecting the digits and arising from the synovium. It is characterized by a proliferation of mononuclear cells and osteoclast-like polykaryocytes. Its propagation to the skin is an exceptional event, which can take place either in localized form in the fingertips (localized type) or in the...

giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...

Fibroma of the tendon sheath (FTS) is a rare, benign, soft tissue lesion. Clinically, FTS presents similarly to the more common giant cell tumour of the tendon sheath. It can be distinguished histologically by the lack of giant cells, foamy histiocytes and synovial cells. The author presents a case of FTS involving the flexor tendon to the fourth metacarpal following repetitive trauma. A 42 yea...

Introduction. Tenosynovial giant cell tumors (TGCT) emerge from the synovium and can behave aggressively. Surgical resection is the standard treatment. However, up to half of the patients with diffuse type show recurrences. Several additional treatments have been applied to reduce recurrences; none of these treatments was proven to be superior to surgical resection solely. This article describe...

The transcription factor LMO2 is involved in vascular and hematopoietic development and hematolymphoid neoplasia. We have demonstrated that LMO2 is expressed nearly ubiquitously in native and neoplastic vasculature, including lymphatics. LMO2 reactivity is otherwise virtually absent in nonhematolymphoid tissues except in breast myoepithelium, prostatic basal cells, and secretory phase endometri...
