A list of a few of the less common dental soft tissue lesions
Dental soft tissue lesions that I think are interesting.
Epulis granulomatosa is found in poorly healing post extraction sites. The lesion just needs excision.
Epulis fissuratum is excess tissue grow from a poorly fitting denture.
Mucous Membrane Pemphigoid (MMP)
MMP is one of several auto-immune conditions that are both difficult to accurately diagnosis and difficult to effectively treat. Treatments are simply managing the symptoms. Differentials include erythema multiforme, Stevens Johnson syndrome, and other autoimmune blistering diseases such as pemphigus vulgaris, bullous pemphigoid, epidermolysis bullosa acquisita, and linear IgA bullous dermatosis.
The differential between erythema multiforme with ANUG and herpetic gingivostomatitis with ANUG is tricky. If you see vesicles or honey crusted lips then think herpetic. Punched out papilla is a sign of ANUG. This is a tricky case and diagnosis.
Oral chronic graft-versus-host disease
There are many soft tissue issues with this disease. The disease happens to bone marrow transplant patients.
Unknown soft tissue lesions
This one is most likely an ischemic event brought on from the injection, trauma from surgery, or the healing process. It is possible that is is a chemical burn but seems unlikely with the clear delineation of the lesion along the mucogingival junction. This cologne burn does look similar and appears to stay on the keratinized tissue.
