Answer

Varicella-zoster virus may present with exclusive follicular involvement.  Most patients present with erythematous hyperkeratotic papules in a dermatomal distribution; however, dissemination can occur in immunocompromised patients. [21] In contrast to the characteristic lesions seen in most herpes infections, vesicles typically do not occur. Biopsy is often required to confirm the diagnosis. [20]
