A case of congenital Langerhans cell histiocytosis with skin and thymic lesions: Exploring the prognostic value of thymus involvement

Abstract

Thymus evaluation is not included in the guidelines of the Histiocyte Society, so its prevalence, management and prognosis are not well established. We present a newborn with self-healing cutaneous LCH and thymic involvement that was evaluated with a thoracic ultrasound. With the current evidence we are unable to predict the prognosis of the thymus association in neonatal LCH. We suggest that performing thymic ultrasound study, which is a non-invasive technique, would allow us to know the incidence of thymic involvement and its role on prognosis.
