Symptoms of Oral Herpes Zoster

Herpes zoster (shingles) is a relatively well-known skin condition. Many people encounter it during their lifetime. When localized herpes zoster develops, small, distinct vesicles appear on the skin surface. Upon rupture of these vesicles, fluid leaks out. Additionally, the affected area may become warm, itchy, and painful. So, what are the symptoms of oral herpes zoster? Let’s take a closer look.

Symptoms of Oral Herpes Zoster

Herpes zoster is a neurocutaneous disease caused by the varicella-zoster virus (VZV). It commonly affects the head and face, neck, chest, waist, and legs. In some cases, it may involve the cornea; if the facial nerve is affected, skin lesions may also appear on the tympanic membrane or external auditory canal. Oral herpes zoster, however, is relatively rare. When it does occur, manifestations may include tongue erythema and swelling, small vesicles, ulcers, tongue pain, and headache. Patients may also present with tonsillar and pharyngeal erythema and sore throat—symptoms easily mistaken for tonsillitis.

Oral herpes zoster can also mimic dental pain, leading to misdiagnosis as pulpitis. Some patients experience tongue pain along with erythema and swelling of the tongue surface and floor-of-mouth mucosa, accompanied by ulcers—findings frequently misdiagnosed as recurrent aphthous stomatitis (canker sores). Therefore, when managing suspected oral herpes zoster, clinicians must carefully obtain the patient’s medical history and perform thorough physical examinations to avoid misdiagnosis, ensure accurate diagnosis, and promptly alleviate patient discomfort.

The above outlines the key clinical features of oral herpes zoster. We hope this information proves helpful to you.
