[Giant cell chondroma of soft tissues. Apropos of a case and review of the literature].
Soft tissue chondroma is a benign cartilaginous tumour most often located at the extremity of the upper limbs. We report a very unusual case of soft tissue chondroma due to its location in the sole of the foot resulting in delayed diagnosis. Diagnosis of soft tissue chondroma was confirmed by microscopic examination and by immunohistochemistry showing S 100 protein in the cells of mature and immature areas. The presence of numerous giant cells is exceptional. Labelling of the giant cells by KP 1 protein in the present case suggest that they are derived from macrophages.
