Concurrent pityriasis rosea and Bell's palsy

Pityriasis rosea is a dermatological disease with a well-documented clinical appearance, but less is known about causes and treatment. Bell's palsy is a neurological condition leading to acute idiopathic hemifacial paralysis. Recent studies indicate that human herpesvirus (HHV) 6–7 reactivation may be a contributing factor to both conditions. We report a case of the 2 concurrent diagnoses that supports a common contributing factor and suggests further awareness and research into the role HHV 6–7 may play in the aetiology of both conditions.
