RESUMO
Immune checkpoint inhibitors (ICIs) can cause immune-mediated cutaneous adverse events, including sarcoid-like reactions. The aim of this study was to retrospectively analyze clinical and histologic data from patients who developed cutaneous sarcoid-like reactions between 2019 and 2022 while under treatment with ICIs. We studied 7 patients (6 women and 1 man) with a median age of 65years. Median time to onset of symptoms was 4months. The most common presentation was papular sarcoidosis of the knees followed by subcutaneous sarcoidosis. Diagnosis was confirmed histologically in all cases, and no differences were observed relative to idiopathic sarcoidosis. Discontinuation of ICI therapy was required in just two patients. ICI-induced sarcoid-like reactions tend to be mild and generally do not require treatment discontinuation. Histologic confirmation is essential for distinguishing these reactions from tumor progression.

Los inhibidores de puntos de control inmunitario (ICI) pueden producir toxicidades cutáneas inmunomediadas entre las que se encuentran las reacciones sarcoideas. Nuestro objetivo fue analizar retrospectivamente los datos clínicos e histológicos de los pacientes en tratamiento con ICI que desarrollaron reacciones sarcoideas cutáneas entre 2019 y 2022. Se incluyeron siete pacientes (seis mujeres y un varón, con una edad mediana de 65años). La mediana de tiempo de instauración de la clínica fue de 4meses y la forma de presentación más frecuente fue la sarcoidosis papulosa de las rodillas, seguida de la sarcoidosis subcutánea. En todos se confirmó el diagnóstico histológicamente y no se observaron diferencias respecto a la sarcoidosis idiopática. Solo en dos casos fue preciso retirar la inmunoterapia. Las reacciones sarcoideas por ICI suelen ser leves y no suelen requerir la interrupción del tratamiento. Es fundamental obtener una confirmación histológica para distinguirlas de la progresión tumoral (AU)
