RESUMEN
Abstract The frequency of the use of drugs that act on the epidermal growth factor receptor (EGFR) is increasing, with the consequent onset of cutaneous toxicity, specifically acneiform eruption. The authors extensively review the topic, focusing on describing how these drugs can affect the skin and its appendages, that is, the pathophysiology that encompasses the cutaneous toxicity related to the use of EGFR inhibitors. In addition, it was possible to list the risk factors that may be associated with adverse effects of these drugs. Based on this recent knowledge, the authors expect to aid in the management of patients who are more vulnerable to toxicity, reduce morbidities, and improve the quality of life of patients undergoing treatment with EGFR inhibitors. Other issues related to the toxicity of EGFR inhibitors, such as the clinical aspects of the acneiform eruption grades, and other different types of cutaneous and mucosal reactions, are also included in the article.

A onicocriptose é uma doença ungueal frequente, que afeta mais comumente os pododáctilos e apresenta algumas variantes, dentre as quais a pouco conhecida "unha em arpão". O diagnóstico costuma ser clínico, e o tratamento cirúrgico emprega diferentes técnicas descritas na literatura. Relatamos o caso de um paciente masculino, 25 anos, com unha em arpão no hálux esquerdo, e a técnica cirúrgica utilizada para o tratamento com excelente resultado
Onychocryptosis is a frequent nail disease, which most commonly affects the toes. It has some variants, including the little known "Harpoon Nail". The diagnosis is usually clinical, and the treatment is surgical, with different techniques described in the literature. We report the case of a 25-year-old man with a harpoon nail on the left hallux and the surgical method used for treatment with excellent results
