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.
软组织软骨瘤是一种良性软骨肿瘤，最常位于上肢末端。我们报告一例非常罕见的软组织软骨瘤病例，因其位于足底导致诊断延迟。软组织软骨瘤的诊断通过显微镜检查和免疫组织化学得以证实，免疫组织化学显示成熟和未成熟区域的细胞中有S 100蛋白。大量巨细胞的存在很罕见。在本病例中，巨细胞被KP 1蛋白标记，提示它们来源于巨噬细胞。
