ENCHONDROMA AND CHONDROSARCOMA GI OF THE FOOT (CLINICAL OBSERVATION)

Abstract

Abstract. Among all neoplasms of the skeleton, enchondroma is 12%, among benign bone neoplasms - 10 - 27%. Frequent localization of enchondroma - short tubular bones of the hands and feet. It is possible to transform an enchondroma of the foot into a chondrosarcoma. Clinical guidelines with a sufficiently substantiated clear diagnostic and therapeutic tactics for enchondromas and chondrosarcomas of the first degree have not been developed to date. The aim of the study was to evaluate the effectiveness of intralesional resection with adjuvant chemical ablation in the treatment of enchondroma and chondrosarcoma of the first degree of the toe on a clinical example. Materials and Methods: A 64-year-old female patient with long-term symptoms on the side of the 5th toe of the right foot and a significant progression of these symptoms over the past three months underwent removal of the soft tissue component of the tumor of this finger, intralesional resection of its distal phalanx, and adjuvant chemical ablation. Healing by primary intention. According to the histological examination, the excised tissue corresponded to an enchondroma with areas of degeneration into grade I chondrosarcoma. Results: The patient was followed up for two years after the operation. There was no tumor recurrence. The patient did not experience pain, difficulty walking, considered herself practically healthy. Conclusion: the above clinical observation confirms that intralesional resection with adjuvant chemical ablation in the treatment of enchondroma and chondrosarcoma of the first degree of the foot allows to avoid relapses and ensure good function in the near and long term.
