Chronic Herpes Zoster

HZ persisting for more than 1 month is seen almost exclusively in HIV infected patients with low CD4 counts and ­occasionally in organ transplant recipients receiving immunosuppressive medications or in patients undergoing cancer chemotherapy regimens.60 Chronic or persistent HZ occurs in three forms: 1.Hyperkeratotic HZ with persistently thickly crusted verrucous lesions which may be seen alone or in association with vesicular or ulcerated lesions.61 - 63 They are usually very chronic (months or years) and are often resistant to acyclovir. The unusual appearance of the hyperkeratotic lesions may be due to coinfection with other organisms such as Candida albicans, Mycobacterium-avium complex (MAC) or Pityrosporum species.
