The incidence of primary cutaneous melanoma continues to increase each year. Melanoma accounts for the majority of skin cancererelated deaths, but treatment is usually curative following early detection of disease. In this American Academy of Dermatology clinical practice guideline, updated treatment

Background: Even after the description of papuloerythroderma of Ofuji (PEO) in 1984, little is known about this clinical entity. Objective:To report on 2 new cases of PEO and review of the worldwide literature on this topic. Methods: Article citations were searched on several biomedical search engines (PubMed, EMBASE, SCOPUS, Google Scholar). Papers were retrieved either online or in print. Results: A grand total of 170 PEO cases were identified. Most patients were older than 55 years and of Asian or white descent, with an overall male/female ratio of 4.0. Itch and the deck-chair sign were observed in all patients. Peripheral eosinophilia, lymphocytopenia and increased serum IgE were common findings. Histopathology mostly showed aspecific inflammation, while 17 showed histological features of cutaneous T-cell lymphoma (CTCL). Atopy, malignancies, infections and drugs were rarely linked to PEO. Conclusion: PEO represents a rather monomorphous entity both clinically and, with the remarkable exception of CTCL, also histologically. Nonetheless, no causative factor could be identified in the vast majority of cases. An etiological classification and diagnostic criteria are proposed in the attempt to contribute framing this puzzling clinical entity.

Main Outcome Measures: Age-adjusted melanoma incidence and stage at diagnosis. Results: Of 41 072 cases of melanoma, 39 670 cases were reported for white non-Hispanics (WNHs), 1148 for white Hispanics (WHs), and 254 for blacks. Melanoma incidence rates increased by 3.0% per year among WNH men (PϽ .001), 3.6% among WNH women (PϽ .001), 3.4% among WH women (P = .01), and 0.9% among WH men (P =.52), while remaining relatively stable among black men and women. Both WHs and blacks had significantly more advanced melanoma at presentation: 18% of WH and 26% of black patients had either regional or distant-stage melanoma at diagnosis compared with 12% of WNH patients. The proportion of distant-stage melanoma diagnosed among WHs and blacks changed little from 1990 to 2004, compared with a steady decrease in the percentage of melanoma cases diagnosed at distant stage among WNHs (PϽ .001). Such differences in the time trends of the proportion of distant-stage melanoma remained after excluding in situ cases. Conclusions: The rising melanoma incidence among WNHs and WHs emphasizes the need for primary prevention. The persistence of disparity in melanoma stage at diagnosis among WHs, blacks, and WNHs warrants closer examination of secondary prevention efforts in minority groups.
