Maffucci syndrome (MS, OMIM 166000) is an extremely unusual, nonhereditary, multisystemic disorder that is characterized with multiple enchondromas and vascular lesions, most of which are spindle cell hemangiomas. Complications of MS, such as bone deformities and dysfunction caused by enchondromas, usually increase during childhood and adolescence. Malignant transformation of enchondromas and other malignancies are the most severe complications.

Article Synopsis
  • - Maffucci syndrome is a rare skeletal disorder marked by multiple enchondromas and soft tissue hemangiomas, with recent research showing a link to mutations in the IDH1/2 genes.
  • - This study presents the first case of Maffucci syndrome with an IDH1 mutation, specifically an R132C substitution, found in a 32-year-old man who had a hemangioma in his oral mucosa.
  • - The hemangioma was surgically removed, and follow-up after over a year shows no tumor recurrence, with monitoring ongoing for any potential recurrence of the hemangioma.

Maffucci syndrome is a rare, highly variable somatic mosaic condition, and well-known cancer-related gain-of-function variants in either the or genes have been found in the affected tissues of most reported individuals. Features include benign enchondroma and spindle-cell hemangioma, with a recognized increased risk of various malignancies. Fewer than 200 affected individuals have been reported; therefore, accurate estimates of malignancy risk are difficult to quantify and recommended surveillance guidelines are not available.
