El desprendimiento completo de la uña (onicomadesis) es poco frecuente en la infancia y produce alarma entre los familiares y cuidadores de los niños. Puede deberse a una gran variedad de patologías locales y sistémicas o aparecer tras la exposición a determinados fármacos, aunque la mayoría de los casos son idiopáticos. Presentamos dos casos de onicomadesis con distintos factores desencadenantes. En ambos, las alteraciones ungueales se resolvieron espontáneamente en pocas semanas (AU)
Complete nail shedding (onychomadesis) in children is a rare condition and it may be a cause of concern among patients family and caregivers. This condition has been associated with a great number of local or systemic diseases and drug exposure, although most cases are idiopathic. We present two patients with different triggering factors of onychomadesis. Nail changes resolved spontaneously in a few weeks in both cases (AU)

One important differential diagnosis of facial erythema in a patient receiving an allogeneic bone marrow transplant (BMT) is acute graft-versus-host disease (GVHD). Demodex folliculorum has been rarely implicated in the development of facial rashes in immunosuppressed patients, including BMT recipients. We report the case of a patient, suffering from acute lymphoblastic leukemia, who after bone marrow transplantation developed a facial rash due to D. folliculorum mimicking GVHD. Differential diagnosis of facial rashes and demodicidosis after BMT is reviewed.

El talón negro (petequias del calcáneo) es una lesión asintomática, de etiología traumática, benigna y autolimitada, que suele afectar a adolescentes y adultos jóvenes deportistas. Su localización más frecuente es en la parte posterior o posterolateral de uno o ambos talones. Se trata de la expresión clínica de una hemorragia dérmica con eliminación transepidérmica (estrato córneo).Su evolución habitual es la completa desaparición si cesa la actividad causal, en muchos casos el deporte. Por su carácter asintomático y benigno, no precisa tratamiento. Su importancia radica en el crucial diagnóstico diferencial que se establece con las lesiones pigmentadas, entre ellas con el melanoma maligno. La localización de la lesión, su bilateralidad, la ausencia de síntomas y su aparición en un joven deportista son importantes claves diagnósticas, que pueden permitir establecer un diagnóstico correcto y evitar una biopsia cutánea innecesaria (AU)
Black heel (calcaneal petechiae) is an asymptomatic lesion caused by trauma. It is benign and self-limited, and usually occurs in teenagers and young athletes. In most cases, it is located on the posterior or posterolateral part of one or both heels. It is the clinical expression of a haemorrhage initially located in the dermis that is eliminated through the epidermis(corneal layer). It tends to disappear completely when the causal activity stops. Treatment is not compulsory due to its asymptomatic nature and its spontaneous resolution. However, differential diagnosis is very important to rule out malignant melanoma. The location of the injury, its bilaterality, the absence of symptoms and its development in a young sportsman are important diagnostic clues that can lead to the correct diagnosis, thus avoiding an unnecessary skin biopsy (AU)
