Rapidly expanding thenar eminence ganglion: a case report.
BACKGROUND
This study documents the first reported case of a rapidly growing (volar) thenar eminence ganglion arising form the first carpometacarpal joint, masquerading as a sarcoma. The discussion informs the hand surgeon on the evidence regarding the unusual presenting features.


METHODS
An 85 year old left hand dominant female presented with a six week history of rapidly growing lump on the thenar eminence. Clinical examination revealed a non-tender large lobulated mobile swelling measuring 5 x 4 cm and involving the whole thenar eminence.


CONCLUSIONS
Ganglia may present from the thenar eminence and are a source of diagnostic confusion.
