Figure 12-39. Herpes of the buttock. The diagnosis is suspected because of the classic presentation of recurrent disease with highly characteristic grouped vesicles of uniform size on an erythematous base. This presentation is seen almost exclusively in women. Recurrences may be frequent and very annoying; suppressive therapy can greatly improve the quality of life.

Figure 12-35.  Recurrent oral-labial herpes can appear on the lips or surrounding skin. Patients unaware of this do not understand that lesions on the chin, nose, or cheeks can be ?cold sores.? The typical grouped crusts support the diagnosis. Impetigo is often suspected. Impetigo does not present as a group of highly uniform small crusts.
