Oncological and functional results of cryosurgical therapy of enchondromas and chondrosarcomas grade 1.

Background And Objectives: Cryosurgery using liquid nitrogen is used as adjuvant treatment after intralesional resection of bone tumours to induce cell death. It is applied to enlarge the oncological margins of resection and to reduce the local recurrence rate. The objective of this study is to analyze the oncological and functional results.

Angiosarcoma with malignant peripheral nerve sheath tumour developing in a patient with klippel-trénaunay-weber syndrome.

Purpose: We discuss the coexistence of Klippel-Trénaunay-Weber syndrome with various malignancies, the possible histogenetic pathways and therapeutic implications.

Patient: We report on a 46-year-old man presenting with increasing pain and swelling of his right lower leg after fracturing his fibula. Since birth he was known as having the uncommon syndrome of Klippel-Trénaunay-Weber of his right lower leg.

Intraosseous schwannoma (neurilemmoma) of the cervical spine.

Purpose: To report on an extremely rare tumour located in the cervical spine, its treatment and result. Review of the literature.

Patient: Case report of a 38-year-old woman with an intraosseous schwannoma of the cervical spine.

The cryosurgical treatment of chondroblastoma of bone: long-term oncologic and functional results.

Background: Chondroblastoma of bone is a rare tumor that occurs most often in the epiphysis or apophysis of long bones. This benign tumor sometimes shows aggressive or malignant behaviour, and rarely metastases occur. Since wide resection often leads to growth impairment, intra-lesional curettage followed by an adjuvant therapy is developed to decrease the negative effects on growth and function without increased recurrence rates.
