Angio-fibro-lipomatous hamartoma is a benign adipose tissue tumor very rarely seen in musculoskeletal distribution, and its incidence in the knee joint has never been reported. The patient in our case presented with knee pain of 2 years' duration, following blunt trauma. Preoperatively, veno-lymphatic malformation/hemangioma was considered as the diagnosis. Only after arthroscopic excision biopsy, histopathological examination, retrospective radiological analysis, and a review of literature, we were able to diagnose this rare condition. The histopathological picture of this benign adipose tissue tumor contained a mixture of mature adipose tissue and fibrous and vascular tissues. Here, in this case report, we discuss about PTEN gene causing PTEN hamartoma of soft tissue and angiolipoma presentations and its variants.
