B. Herpes simplex.
C. Coxsackie A16.
D. Pemphigus vulgaris.
Answer: Aphtous stomatitis
The 3 main clinical types of recurrent aphthous stomatitis (RAS) are:
• Minor aphthous ulcers (MiAUs, 80% of all RAS).
• Major aphthous ulcers (MjAUs).
• Herpetiform ulcers.
This patient had minor aphthous stomatitis. Most relevant studies have found hematinic (eg, iron, folic acid, vitamin B12) deficiencies in as many as 20% of patients with recurrent ulcers. In addition, deficiencies of vitamins B1, B2, and B6 have been noted in some patient cohorts. Workup for a hematinic deficiency is warranted if the lesions are frequent or if they have major subtype.
Treatment is typically with a topical corticosteroid when there is a limited or minor disease, such as in this sitaution.
