two rare cases of extra-articular diffuse variant giant cell tumor of the tendon sheath are presented, at the elbow of a 68-year-old female and the foot of a 56-year-old male. both patients presented with a palpable masses and marginal excision was performed; histological sections confirmed the diagnosis of extra-articular giant cell tumor. no adjuvant therapy was administered. at the last foll...

This is an isolated case of a giant cell tumor originating from the synovium of the hip, consistent with Pigmented Villonodular Synovitis (PVNS) and associated with concurrent Femoroacetabular Impingement (FAI). There is a paucity of literature on this condition. This case report will add to the literature on hip pathology that may be treated using arthroscopic surgery.

Pigmented villonodular synovitis (PVNS) is an uncommon lesion nearly always occurring in the large synovial joints of the extremities. Involvement of the vertebral column is rare , having been previously reported only four times. The present report describes the myelographic and postmyelographic CT appearance of PVNS arising from a lumbosacral facet joint and extending within the spinal canal a...

Sweet's syndrome (acute febrile neutrophilic dermatosis) was first described in 1964.

Sweet's syndrome has particularly been described in association with neoplastic, infectious and immunological diseases. The pathogenesis of Sweet's syndrome can be...
