The mucocutaneous herpetic infections are common in a variety of clinical
conditions and can be presented as vesicles, ulcers, crusts and pustules.
When clinical diagnosis is not evident, as in immunossupressed hosts, viral
cultures and Tzank smears could be used for diagnosis (GT Nahass et al.
1992. In AIDS patients the emergence of acyclovir resistant strains are not
uncommon and the development of atypical herpetic lesions could drive to
incorrect diagnosis and therapeutic (PA Chatis et al. 1989).
