Soft tissue plasmacytosis. A case report.

Plasma cell gingivitis was identified during the early 1970s as an allergic reaction to a component in a chewing gum. The clinical picture was described as bright erythema of the entire gingiva, loss of stippling and generalized swelling. Today, many allergens appear to be responsible for this problem.

An overview of oral frena and their association with multiple syndromic and nonsyndromic conditions.

The development of abnormal oral frena is an important diagnostic feature of several syndromic states. Five such syndromes are reviewed which include Ehlers-Danlos syndrome, infantile hypertrophic pyloric stenosis, holoprosencephaly, Ellis-van Creveld syndrome, and oral-facial-digital syndrome. Each syndrome exhibits relatively specific frena abnormalities, ranging from multiple, hyperplastic, hypoplastic, or absent.
