Clinical presentation and appearance of the ulcer(s) often suggest the diagnosis.
Pathology tests (including FBC) are usually only indicated for severe, indolent or recurrent ulcers.
Enterovirus (coxsackievirus) antibodies are not useful.
Any solitary ulcer persisting for more than 3 weeks should be biopsied.
Systemic disorders, especially
Lesion biopsy with IF. Pemphigus antibodies and pemphigoid antibodies.
