RESUMO
Antecedentes: Los pacientes oncológicos pediátricos pueden desarrollar lesiones dermatológicas secundario a terapia antineoplásica, afectando piel, cabello y uñas. Objetivo: Describir las manifestaciones dermatológicas en los pacientes oncológicos pediátricos hospitalizados. Métodos: Estudio descriptivo transversal llevado a cabo en sala de Hemato- Oncología Pediátrica, Hospital Escuela, período enero-junio 2022. Fueron incluidos 86 pacientes que presentaron manifestaciones dermatológicas durante el período del estudio. Para el análisis se generaron resultados como frecuencias, porcentajes y estadística descriptiva. La proporción de pacientes con manifestaciones dermatológicas se determinó como número total de pacientes con diagnósticos dermatológicos en el período del estudio/número total de pacientes hospitalizados en la sala de Hemato-Oncología Pediátrica multiplicado por 100. Resultados: La edad media fue 9.4 años (DS +/-5.0; rango: 5 meses-18 años). Predominó sexo masculino 62.8% (54/86), procedencia de Francisco Morazán 41.9% (36/86) y ambiente rural 53.5% (46/86). El diagnóstico oncológico fue leucemia linfoblástica aguda 60.5% (52/86), la clasificación fue malignidades hematológicas 67.4% (58/86). El principal fármaco oncológico administrado fue Vincristina 76.7% (76/86). El principal agente antineoplásico administrado fue alcaloides vegetales 75.6% (65/86). El tipo de lesión eritema 38.5% (34/86); la localización de la lesión fue en piel 47.6% (41/86). El diagnóstico dermatológico fue alopecia y mucositis 36.0% (31/86) respectivamente. La proporción de lesiones dermatológicas fue de 65.1% (86/132) y fueron clasificadas como secundarias al tratamiento oncológico 82.6% (71/86). Discusión: La proporción de lesiones dermatológicas fue 65%, siendo las principales manifestaciones alopecia y mucositis, posiblemente secundario a la administración de terapia antineoplásica específicamente alcaloides vegetales, similar a lo reportado en la literatura...(AU)

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.

Tick bites can cause a number of local inflammatory reactions, which are often difficult to differentiate from those induced by other arthropod bites or stings. These include erythematous nodular or pustular lesions, erosive plaques, annular lesions of erythema chronicum migrans, and both scarring and nonscarring inflammatory alopecia. We report a case of nonscarring alopecia in a 21-year-old male who reported a recent history of tick bite to the scalp. The biopsy demonstrated a dense pseudolymphomatous inflammatory infiltrate with numerous eosinophils associated with hair follicle miniaturization and an elevated catagen-telogen count. Signs of external rubbing, including lichen simplex chronicus and the "hamburger sign", were also visualized and are indicative of the associated pruritus. To the authors' knowledge, this is the fifth report of nonscarring tick bite alopecia in the literature and the first in an adult patient. This text will review the classic clinical presentation, histologic findings, and proposed mechanism of tick bite alopecia.

Primary follicular mucinosis is a rare dermatosis characterized by the accumulation of mucin in the follicular epithelium and sebaceous glands. Clinically, it is characterized by the presence of papules or well-circumscribed and infiltrated plaques. In this paper, we report the case of a female patient, seven years old, evolving for three months with an asymptomatic, erythematous and infiltrated plaque located in the chin region. The research of thermal, pain and tactile sensitivity was inconclusive. Histological findings confirmed the diagnosis of follicular mucinosis. There was regression of the lesion with the use of medium potency topical corticosteroids for 20 days. The pathogenesis of follicular mucinosis remains unknown, being in some cases associated with lymphoproliferative disorders. In endemic areas of leprosy, isolated and infiltrated follicular mucinosis lesions should be further differentiated from leprosy.
