Evaluation of peripheral nerve fibers and mast cells in burning mouth syndrome.

Emerging evidence has revealed a cross-talk in the etiopathogenesis of burning mouth syndrome (BMS) related to peripheral nerve fibers (NF) and neuropeptides secreted by mast cells. Here, we investigated the S-100+ density and PGP 9.5+ integrity of peripheral NF and the tryptase+ mast cell density in the oral mucosa of BMS patients and healthy individuals.

Focal Epithelial Hyperplasia (Heck's Disease) in a 57-Year-Old Brazilian Patient: A Case Report and Literature Review.

Focal epithelial hyperplasia (FEH), or Heck's disease, is a rare disease of the oral mucosa associated with infection by some subtypes of human papilloma virus, especially subtypes 13 or 32. The disease is predominantly found in children and adolescents with indigenous heritage, but other ethnic groups can be affected worldwide. To the best of the authors' knowledge, it has not been reported in Brazil's elderly population.

Epithelial inclusion cyst after free gingival graft: a case report.

There have been few case reports of cystic lesions occurring after gingival grafting. There are three reports of this type of sequela after connective tissue grafting, but this is the first known case of a cystlike lesion developing secondarily to a free gingival graft procedure. The bulky tissue, which had developed under the previously grafted area, was properly excised under local anesthesia.
