Abstract
A giant cell tumor with local aggressiveness and penetration of cartilage is quite rare. We present a case of fungating giant-cell tumor of lower end of the ulna with wrist involvement including penetration of cartilage and diaphysis. Involvement with all these characteristics, according to the literature reviewed, is the first case of its type. We are of the opinion that the fungation may be due to incision and drainage and delayed presentation at tertiary care centre.
Highlights
Giant-cell tumours of bone (GCTOB) are benign, locally aggressive, primary bone tumours first described by Coopert in 1818.1 They occur most commonly in the distal femur, proximal tibia and distal radius of skeletally mature patients.[2]
Penetration of articular cartilage by giant-cell tumor is rare in the absence of fracture
The material was sent for histopathological examination which confirmed that it was a giant-cell tumor on gross examination, the excised tumor was as an expansile mass involving both the epiphyseal and metaphyseal part of the lower end of the ulna which had a residual thin rim of bone present, except on the medial aspect where there was destruction of bone with soft tissue extension of tumor and skin ulceration
Summary
Giant-cell tumours of bone (GCTOB) are benign, locally aggressive, primary bone tumours first described by Coopert in 1818.1 They occur most commonly in the distal femur, proximal tibia and distal radius of skeletally mature patients.[2]. Fungating giant-cell tumor with local aggressiveness and penetration of cartilage being rare.[5]. It gradually started fungating and progressively increasing in size with continuous oozing from the surface It was a fleshy mass of about 10 cm x 10 cm with continuous oozing and looked aggressive. Shrestha et al Fungating Primary Locally Malignant Giant Cell Tumor Of Ulna – A Case Report ulna with perforation of the cartiligous end. It looked like a malignat tumor arising from the distal end of the ulna (Figure-1a, 1b). The patient again reported after 3 years with a large swelling with mild to moderate pain and without a fungating mass.
