Estudo histopatológico do trajeto de biópsia de tumores musculoesqueléticos malignos

Abstract

Objective: To investigate whether there is any risk of seeding by neoplasic cells along biopsy tracks and to study local histological abnormalities. Methods: This was a prospective study on biopsy tracks in patients who underwent operations due to malignant musculoskeletal tumors between April 2006 and April 2007. Results: Neoplasic cell implantation occurred in 32% of the tracks. The most common histological abnormalities in positive cases were classified as severe fibrosis, mild inflammatory component and severe neovascularization. Conclusion: We suggest that traditional oncological resection of the track should be carried out together with excision of the specimen.
