Oral manifestation of immunoproliferative small intestinal disease. A case report.
A patient with a previous medical history of immunoproliferative small intestinal disease (IPSID) presented with persistent red and ulcerated lesions on her attached gingiva. Despite the obvious long standing gingival inflammation, minimal destruction of alveolar bone had occurred. Following failure of the tissues to respond to routine periodontal therapy, a gingival biopsy was taken. Histological assessment of the specimen revealed several features in common with the intestinal lesions seen in IPSID. In particular, a large plasma cell infiltrate subjacent to the gingival epithelium was noted. There was a marked loss of normal connective tissue morphology and evidence of epithelial degeneration. Treatment has since consisted of palliative measures only. While this is a relatively rare condition, it (as well as other disorders of the immune system) provides a useful insight into the role that the immune system plays in the inflammatory periodontal diseases.
