1) ANUG
2) Diphtheritic lesion
3) Secondary stage of syphilis
4) Desquamative gingivitis
Oral Pathology
Answer: 2
Diphtheritic lesions are caused by Corynebacterium diphtheriae. The hallmark of diphtheria is a tough gray pseudomembrane on mucosal surfaces like the pharynx or oral cavity. Attempting to remove it causes pain and bleeding. Other conditions like ANUG (acute necrotizing ulcerative gingivitis) produce pseudomembranes but are more localized and less gray.
