We report a patient that fulfills the clinical features of inflammatory bowel disease (Crohn) who develops papulopustular lesions, some of which evolve into erythematous plaques with pustules and other into superficial ulcers. The different cutaneous manifestations of inflammatory bowel disease, are reviewed, an entity which includes Crohn's disease and ulcerative colitis, as well as the previously reported cases which developed papulopustular lesions emphasizing their similarities and their differences to our patients and also its probable relationship to malignant pyoderma.
The human papillomavirus (HPV) belongs to a small group of viruses which are known to cause tumors in humans. Not only do they cause benign papillomas, but they are also implicated in the pathogenesis of some malignancies. For this reason, it is important for both the practicing physicians and students to know about recent advances in the study of these viruses. The following is a review of the etiologic role of HPV in non-genital and genital warts, laryngeal papillomas, and their possible roles in several malignancies.

Diffuse fasciitis (DF) shares clinical and pathologic features with systemic (SS) and localized scleroderma. The distinct pathologic feature in DF is involvement of the deep fascia, but it is not known if these changes consistently occur in SS. In this study, ten patients with SS underwent deep biopsies for evaluation of the fascia. All cases showed typical dermal histologic findings of scleroderma, and five cases showed thickening and fibrosis of the fascia. This study provides evidence that fascial involvement is not distinctive of DF but may occur in SS. It appears that thickening of the fascia is another morphologic feature shared between DF and SS.
The case of a 2-year-old Puerto Rican boy is presented. Clinical and histologic features are detailed because he showed peculiar jet black patches of pigmentation on the fingers of the right hand. This case, except for the lack of progression of the disease after a 2-year period of follow-up, shows many similarities to the case of a Japanese child reported by Furuya and Mishima as "acromelanosis progressiva." This condition is viewed as the epidermal counterpart of pigmentary disorders composed of dermal melanocytes, "epidermal melanocytosis."
