Very small multiple ulcers occurring in groups of up to 11 at a time are best described as which type?

• A. Herpetiform aphthous ulcers
• B. Gingival ulcers
• C. Eczema
• D. Herpes simplex ulcers

Answer: (A)

Very small ulcers that appear in groups are best described as herpetiform aphthous ulcers. This form of recurrent aphthous stomatitis creates numerous tiny ulcers that occur in crops or clusters, often up to about a dozen at a time, rather than a single large sore. The term “herpetiform” reflects the clustered appearance, not a herpes infection, which helps distinguish it from herpes simplex ulcers. These tiny ulcers are typically a few millimetres across and heal within about 1–2 weeks. By contrast, ulcers on the gums would be gingival ulcers, eczema refers to a skin condition, and herpes simplex ulcers usually present with vesicles that rupture into ulcers in specific mucosal areas and have a different clinical pattern.
