Isolated masseter muscle fungal invasion: unmasking the culprit

This case report focusses on a unique and infrequently observed event where an isolated masseter muscle fungal invasion was seen. The patient's symptoms include facial swelling and restricted mouth opening. The rarity of this particular manifestation is emphasised by the fact that there are no previously reported cases where fungal infection was the cause of isolated masseter muscle involvement. This lack of documented cases underscores the novelty and significance of the current case.
