Cocaine is an alkaloid extracted from the leaves of the Erythroxylum coca plant that emerged in the 1970s as a fashionable drug among members of certain social backgrounds. Cocaine abuse is a problem of current interest, which is mostly hidden and underdiagnosed, but dramatically widespread among all socio-economic strata, and with an incidence which is increasing at an alarming rate. There are 1.5 million cocaine consumers in the USA. In Spain, the prevalence of consumption among the population between 15 and 65 years old is higher, reaching 3.1%. Because of this, it seems important to understand and recognize all the mucocutaneous manifestations of cocaine abuse which have been reported in the literature to clarify and to help dermatologists in their daily practice. In this article, we describe the principal mucocutaneous manifestations of cocaine abuse and we review isolated case reports which have been published in the literature. Because the dermatologist may deal with an unknown problem as well as with an already well-known history of cocaine abuse, it seems logical to separate the mucocutaneous manifestations into those which are frequent and highly suggestive, such as those caused by vascular injury, damage to mucosal membranes, infectious diseases or neutrophilic dermatosis, especially when suffered by young people and in consonance with other systemic manifestations and, those which have been reported in the literature as isolated case reports. We also summarize the main aspects of its pathogeny, principal pharmacodynamic and pharmacokinetic characteristics, and diagnostic tools.

Fox Fordyce disease (FFD) has been recently described as an adverse effect of laser hair removal. It is an apocrine gland disorder characterized by pruritus and a folliculocentric papular eruption in apocrine sweat gland areas. Different etiologies have been proposed to be the cause of this entity. It has been suggested that a fisical factor could contribute to FFD phatogenesis. We report a new case of FFD after laser hair removal.

Las fotodermatosis están causadas por una reacción anómala frente al sol y a las fuentes artificiales, generalmente por la radiación ultravioleta. Se dividen en idiopáticas, fototóxicas y fotoalérgicas y secundarias. Su diagnóstico diferencial es difícil por la similitud clínica y la nomenclatura confusa. Los estudios fotobiológicos (el fototest, la fotoprovocación y la prueba de fotoparche) tienen utilidad clínica y son necesarios para el diagnóstico en varias fotodermatosis.

Background: 2D7 and BB1 are thought to be basophil-specific markers. In this study, we tested both antibodies in different skin and mast cell disorders with the aim of determining whether it was possible to differentiate between benign and aggressive presentations of mastocytosis. Methods: Using the antibodies 2D7, BB 1, and c-Kit, we performed an immunohistochemical study of skin biopsy specimens from patients with cutaneous mastocytosis (15 urticaria pigmentosa and telangiectatic macularis eruptive perstans) and liver or bone marrow biopsy specimens from patients with systemic mastocytosis. A basophil leukemia cell line was used as a reference. Peripheral blood basophils from healthy donors were used as controls. Results: We observed intense expression of 2D7 and BB1 in all skin biopsy specimens from patients with cutaneous mastocytosis. Immunostaining of liver and bone marrow specimens from patients with systemic mastocytosis with 2D7 and BB1 antibodies was negative. Specimens from patients with either type of mastocytosis showed similarly strong expression of c-Kit. The basophil cell line showed a 2D7 and a BB1 profile, with intense expression of c-Kit. Peripheral blood basophils exhibited notable immunostaining for 2D7, BB1, and c-Kit. Conclusions: 2D7 and BB1 are expressed in cutaneous mastocytosis, although this expression is lost when mast cell proliferation is systemic, thus reflecting either a different cellular differentiation stage or the presence of basophils in these skin diseases.

Pemphigus vulgaris (PV) is an autoimmune blistering skin disease characterized by suprabasal acantholysis produced as a consequence of desmoglein (Dsg) and non-Dsg autoantibodies binding to several targeting molecules localized on the membrane of keratinocytes. Nitric oxide (NO) may exert a pathogenic function in several immunological processes. We have previously demonstrated that neural nitric oxide synthase (nNOS) plays part in PV acantholysis. Also, our group has described a relevant role for HER [human epidermal growth factor receptor (EGFR) related] isoforms and several kinases such as Src (Rous sarcoma), mammalian target of rapamycin (mTOR) and focal adhesion kinase (FAK), as well as caspases in PV development. Using a passive transfer mouse model of PV, we aimed to investigate the relationship between the increase in nNOS and EGFR, Src, mTOR and FAK kinase upregulation observed in PV lesions. Our results revealed a new function for nNOS, which contributes to EGFR-mediated PV acantholysis through the upregulation of Src, mTOR and FAK. In addition, we found that nNOS participates actively in PV at least in part by increasing caspase-9 and caspase-3 activities. These findings underline the important issue that in PV acantholysis, caspase activation is a nNOS-linked process downstream of Src, mTOR and FAK kinase upregulation.
