On physical and radiologic assessment, a mass at the superolateral edge of the patella and a hyperintense lesion on T2 sequences of magnetic resonance imaging was detected. Excisional biopsy revealed a chondroma of patella. Primary bone tumors of the patella are extremely rare and occurence of chondroma in this localization is very uncommon. Although anterior knee pain is a very frequent and usually harmless, it is essential to consider the more severe disorders such as bone tumors.eninfo:eu-repo/semantics/closedAccessPatellatumorchondromapainArticle361818210.1097/MPH.0b013e318292bc9dQ4WOS:0003372923000332-s2.0-8489182738123669736Q3
