Colonic changes of herpes zoster

The lesions of herpes zoster of the colon were observed in three cases. Small polygonal mucosal blebs or small ulcerations involving a short segment of the colon and appearing in a reasonable time relationship with the cutaneous manifestations either in a corresponding or noncorresponding dermatome should enable diagnosis of this unusual condition. Recognition of this entity in the presence of these skin lesions should be obvious and therefore helpful in avoiding more aggressive and invasive diagnostic procedures.
