Mastocytoma usually presents as a
solitary lesion whereas mastocytosis is a rare skin condition which
typically manifests with or without accompanied systemic symptoms. Although a
few cases of solitary mastocytoma have been documented on mucosa (vulva), none
has been reported on the oral mucosa in the English literature. The present
case is an example of an exceptional rare presentation of solitary mastocytoma
of the oral mucosa.
