Basaloid follicular hamartoma associated with follicular mucinosis and inflammation

Abstract Basaloid follicular hamartoma is a benign, superficial malformation of hair follicles that can be mistaken both clinical and histopathologically for basal cell carcinoma. Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old patient with an asymptomatic congenital lesion on the forehead, which increased in size over the years. Histopathology showed a basaloid follicular hamartoma associated with follicular mucinosis and inflammation. Gorlin-Goltz syndrome was ruled out by clinical examination.

Síndrome de Cushing iatrogénico secundario al mal uso de corticoïdes tópicos: Reporte de un caso pediátrico / Iatrogenic Cushing syndrome due to the misuse of topical corticosteroids: Pediatric case report

Los corticoides se utilizan en el tratamiento de muchas enfermedades dermatológicas, debido a sus efectos antiinflamatorios, inmunosupresores y antiproliferativos. Su uso indiscriminado puede ocasionar serios efectos adversos locales y sistémicos, fundamentalmente, en niños y frente a ciertos factores predisponentes. Si bien los corticoides tópicos son seguros y efectivos, se debe prestar principal atención a factores como la edad del paciente, el estado de la barrera cutánea, la localización, la potencia y el vehículo del corticoide antes de su prescripción, para disminuir la posibilidad de efectos adversos. Se presenta a una paciente de 5 meses de edad, la cual concurrió a la consulta por un hemangioma ulcerado en el glúteo izquierdo asociado a un síndrome de Cushing, debido a la aplicación local de un corticoide tópico durante más de 3 meses para tratar dicha lesión.

Corticosteroids are used in the treatment of many dermatological diseases due to their anti-inflammatory, immunosuppressive and antiproliferative effects. Its indiscriminate use can cause serious local and systemic adverse effects, mainly in children and in the presence of certain predisposing factors. While topical corticosteroids are safe and effective, it is important to pay attention to factors such as patient's age, skin barrier, clinical characteristic and localization of the lesion, potency and vehicle of the corticosteroid before its prescription to reduce the possibility of adverse effects. We present the case of a 5-month-old patient who presented an ulcerated hemangioma in the left buttock. Due to the local application of a topical corticosteroid on the hemangioma for more than 3 months, she developed Cushing's syndrome.
