The Viscous Juncture-Juxta Articular Myxoma

Abstract

Juxta-articular myxoma is an uncommon, benign, hypocellular, bland, myxoid neoplasm of mesenchymal origin occurring within the vicinity of a large joint such as the knee. The neoplasm is exemplified within 16 years to 83 years with a median age at 43 years. A male predominance is observed with a male to a female proportion of nearly 3:1. Localized tissue destruction arising on account of the neoplasm can engender pain or nerve palsy. The minimally cellular tumefaction depicts an abundant, myxoid stroma admixed with a non-malignant proliferation of spindle-shaped cells. Juxta-articular myxoma is immune reactive to vimentin and CD34.
