PLC is a rare disease that represents a diagnostic and therapeutic challenge to the physician. The diagnosis of this condition is suspected clinically and confirmed by histology. It does not have specific treatment, but it responds well to corticosteroids, antibiotics, immunosuppressants and phototherapy with UVB narrowband (UVBnb). The latter has given the best results. It is important to monitor patients for risk of developing lymphoproliferative disorders.
Jellyfish are aquatic organisms, whose number increases under certain conditions of water temperature. They can sting humans, which can be fatal. The liberation of structures known as nematocysts induces the extrusion of the poison, to attack their victims. The poison produces characteristic local and systemic reactions. Since an increased number of these organisms has been detected in our coastline, we review the epidemiology, symptoms and diagnosis of the syndrome produced by the bite, to improve its management.
ResumenIntroducción: El granuloma anular es una dermatosis inflamatoria granulomatosa de carácter benigno y autolimitado. El granuloma anular subcutáneo es una variante poco común, que se presenta casi exclusivamente en niños menores y se caracteriza por la aparición de nódulos de consistencia firme de predominio en extremidades inferiores, glúteos, manos y cuero cabelludo. Objetivo: Reportar un caso de granuloma anular subcutáneo, revisar su diagnóstico diferencial y las opciones terapéuticas actuales. Caso clínico: Paciente de sexo masculino de 4 años. Desde los 2 años y medio con nódulos subcutáneos indurados asintomáticos, inicialmente en dorso de dedo medio mano izquierda, luego en dorso de mano izquierda, primer ortejo derecho, zona frontal izquierda y cuero cabelludo. La biopsia excisional de algunas lesiones de cuero cabelludo fue compatible con granuloma anular subcutáneo. Como tratamiento se indicó clobetasol 0,05% crema 2 veces al día en lesiones por 1 mes, sin cambio en las lesiones. Conclusiones: El granuloma anular subcutáneo debe considerarse dentro del diagnóstico diferencial de nódulos subcutáneos en niños. En la mayoría de los casos se requerirá biopsia y estudio histopatológico de las lesiones para su confirmación diagnóstica. Debido a su tendencia a la resolución espontánea, generalmente se sugiere no tratar y controlar periódicamente.
