Gingival Necrosis Associated with Septic Shock of Unknown Origin in Patient with Systemic Lupus Erythematosus: A Case Report.

A 38-year-old woman with a history of systemic lupus erythematosus presented at our university hospital with fever, fatigue, and oral pain and was urgently admitted based on a diagnosis of septic shock. Initially, dental infection was suspected based on the symptoms and clinical presentation of purpura accompanied by severe tenderness along the marginal gingiva in the maxilla and mandible. However, subsequent investigations, including an oral examination, radiographic studies, and blood cultures, ruled out dental infection as the cause of the septic shock.

Integrated genotypic analysis of hedgehog-related genes identifies subgroups of keratocystic odontogenic tumor with distinct clinicopathological features.

Keratocystic odontogenic tumor (KCOT) arises as part of Gorlin syndrome (GS) or as a sporadic lesion. Gene mutations and loss of heterozygosity (LOH) of the hedgehog receptor PTCH1 plays an essential role in the pathogenesis of KCOT. However, some KCOT cases lack evidence for gene alteration of PTCH1, suggesting that other genes in the hedgehog pathway may be affected.
