Case report: plasma cell gingivitis A.

The plasma cell gingivitis condition, an uncommon, nonmalignant lesion, is characterized by an offending allergen which causes a massive plasma cell infiltration in gingival connective tissue. Occasionally, soft tissue biopsy of affected and normal tissues is necessary for proper diagnosis. Blood analysis may rule out other systematic disorders with oral manifestations.

Crohn's disease: early detection by gingival biopsy.

A definitive diagnosis of Crohn's disease was made in a 31-year-old female patient who presented with a chief complaint of red, burning gingiva and an itchy palate. The microscopic identification of multinucleated giant cells in the gingival biopsy was suggestive of Crohn's disease. This led to a complete medical work-up including an upper and lower bowel series, which confirmed the diagnosis of Crohn's disease.
