The spectrum of the mucocutaneous adverse effects of directed oncologic therapies, such as anti-EGFR, anti-VEGF, anti-TK and anti-BRAF, presents similarities but also differences compared to that of the classic chemotherapeutics. This article reviews the dermatological toxicities of the targeted therapies, with 11 clinical cases, including mucositis and oral toxicities, the acne-like eruptions, nail changes and complications, the «hand/foot» syndrome, radiosensitization, alopecias, xerosis and skin fissures. After a brief clinical case presentation and theoretical issues, the clinical management is discussed in detail.

Background: Toxic epidermal necrolysis (TEN), a severe cutaneous hypersensitivity reaction induced particularly by drugs, is diagnosed when there is a fever of ≥ 38 °C, mucocutaneous symptoms, a rash with multiple erythema, and skin peeling of ≥ 30% of the body surface area. The mortality rate of TEN is high, and thrombocytopenia during treatment can lead to severe outcomes. Intravenous immunoglobulin (IVIg) is used when steroids are ineffective in TEN and may improve mortality; however, thrombocytopenia is a rare adverse event associated with IVIg use.

Background: Mucosal leishmaniasis (ML) is a severe clinical form of leishmaniasis that is characterized by the destruction of the nasal and/or the oral mucosae and appears as a late complication in 5% to 10% of cutaneous leishmaniasis (CL) cases produced by species belonging to Leishmania (Viannia) subgenus. Some strains of Leishmania spp. carry an RNA virus known as Leishmania RNA virus (LRV) that may contribute to the appearance of ML.

The intestinal microbiota influences many host biological processes, including metabolism, intestinal barrier functions, and immune responses in the gut and distant organs. Alterations in its composition have been associated with the development of inflammatory disorders and cardiovascular diseases, including Kawasaki disease (KD). KD is an acute pediatric vasculitis of unknown etiology and the leading cause of acquired heart disease in children in the United States.
