          Abstract

          Regional lymphomatoid papulosis (LyP) accounts for 2-27% of all LyP cases. Several localized dermatoses have been reported in association with Becker's melanosis (BM), e.g. acneiform lesions or lichen planus. Here, we report on regional LyP confined to the area of BM. A 56-year-old man presented with a 1-year history of a steadily increasing number of multiple pruritic red papules developing on the area of BM, which had occurred on his left shoulder during puberty. Histopathological analysis was consistent with regional LyP. Potent topical steroids followed by oral doxycycline did not achieve improvement, while long-term oral bexarotene treatment ameliorated the skin condition. Recently, the proposed entity of ‘persistent agmination of LyP' (PALP) has extended the clinicopathological observations of regional LyP. Since PALP remains controversial, a unifying concept of localized LyP and PALP will be discussed.

          WHO-EORTC classification for cutaneous lymphomas.

          Primary cutaneous lymphomas are currently classified by the European Organization for Research and Treatment of Cancer (EORTC) classification or the World Health Organization (WHO) classification, but both systems have shortcomings. In particular, differences in the classification of cutaneous T-cell lymphomas other than mycosis fungoides, Sezary syndrome, and the group of primary cutaneous CD30+ lymphoproliferative disorders and the classification and terminology of different types of cutaneous B-cell lymphomas have resulted in considerable debate and confusion. During recent consensus meetings representatives of both systems reached agreement on a new classification, which is now called the WHO-EORTC classification. In this paper we describe the characteristic features of the different primary cutaneous lymphomas and other hematologic neoplasms frequently presenting in the skin, and discuss differences with the previous classification schemes. In addition, the relative frequency and survival data of 1905 patients with primary cutaneous lymphomas derived from Dutch and Austrian registries for primary cutaneous lymphomas are presented to illustrate the clinical significance of this new classification.

            EORTC, ISCL, and USCLC consensus recommendations for the treatment of primary cutaneous CD30-positive lymphoproliferative disorders: lymphomatoid papulosis and primary cutaneous anaplastic large-cell lymphoma.

            Primary cutaneous CD30(+) lymphoproliferative disorders (CD30(+) LPDs) are the second most common form of cutaneous T-cell lymphomas and include lymphomatoid papulosis and primary cutaneous anaplastic large-cell lymphoma. Despite the anaplastic cytomorphology of tumor cells that suggest an aggressive course, CD30(+) LPDs are characterized by an excellent prognosis. Although a broad spectrum of therapeutic strategies has been reported, these have been limited mostly to small retrospective cohort series or case reports, and only very few prospective controlled or multicenter studies have been performed, which results in a low level of evidence for most therapies. The response rates to treatment, recurrence rates, and outcome have not been analyzed in a systematic review. Moreover, international guidelines for staging and treatment of CD30(+) LPDs have not yet been presented. Based on a literature analysis and discussions, recommendations were elaborated by a multidisciplinary expert panel of the Cutaneous Lymphoma Task Force of the European Organization for Research and Treatment of Cancer, the International Society for Cutaneous Lymphomas, and the United States Cutaneous Lymphoma Consortium. The recommendations represent the state-of-the-art management of CD30(+) LPDs and include definitions for clinical endpoints as well as response criteria for future clinical trials in CD30(+) LPDs.
