Hand, foot, and mouth disease (HFMD) is a common infection caused by a group of enteroviruses. [10] It typically begins with a fever and feeling generally unwell. [10] This is followed a day or two later by flat discolored spots or bumps that may blister, on the hands, feet and mouth and occasionally buttocks and groin.
In herpetic gingivostomatitis, lesions can be found in these locations, but they are almost always accompanied by ulcerations on the gums, lips, tongue or buccal mucosa and/or by hyperemia, hypertrophy or hemorrhage of the gums. [15] Hand Foot and Mouth Disease: Similar to herpangina, hand foot and mouth disease occurs predominantly in children.
Herpangina, also called mouth blisters, is a painful mouth infection caused by coxsackieviruses.Usually, herpangina is produced by one particular strain of coxsackie virus A (and the term "herpangina virus" refers to coxsackievirus A), [1] but it can also be caused by coxsackievirus B or echoviruses.

This is herpes labialis (a cold sore), and is sometimes termed "angular herpes simplex". [2]
In a few cases a sore mouth can develop, and if so pain is sometimes made worse by toothpastes, or hot or spicy food. [7] The lesions can extend to involve the palate. [7] Plasma cell cheilitis appears as well defined, infiltrated, dark red plaque with a superficial lacquer-like glazing. [5] Plasma cell cheilitis usually involves the lower lip. [3]
