RIBEIRO, Marcelo Barbosa et al. Histopathological study on biopsy track in malignant musculoskeletal tumors. Acta ortop. bras. [online]. 2009, vol.17, n.5, pp. 279-281. ISSN 1413-7852. http://dx.doi.org/10.1590/S1413-78522009000500005.
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.
