RESUMEN
La Histiocitosis de Células de Langerhans (HCL) es una enfermedad poco común caracterizada por la proliferación clonal de células dendríticas inmaduras que infiltran de forma local o difusa a distintos sistemas, y que afecta principalmente a niños. Presentamos el caso de un hombre de 38 años con historia de caída de múltiples piezas dentales de larga data, sin asociación a traumatismo, tabaquismo ni a mala higiene dental. Tomografía Computada (TC) de cráneo que mostró múltiples lesiones líticas mandibulares. El resultado de biopsia mandibular e inmunohistoquímica eran compatibles con el hallazgo de HCL. Durante su evolución, cursa con poliuria, polidipsia y nicturia, confirmando mediante estudio hormonal diabetes insípida y panhipopituitarismo. Resonancia Magnética (RM) cerebral muestra neoplasia hipotalámica con compromiso infundibular e imagen sugerente de granuloma hipofisiario. Se decide defocación maxilobucofacial, suplementación hormonal, junto con quimioterapia y radioterapia. El paciente evolucionó favorablemente.
Langerhans-cells Histiocytosis (LCH) is a rare disease characterized by the clonal proliferation of immature dendritic cells that locally or diffusely infiltrate different systems, mainly affecting children. We present the case of a 38-year-old man with a long-standing history of multiple tooth loss without association with trauma, smoking, or poor dental hygiene. Skull computed tomography (CT) showed multiple lytic jaw lesions. Jaw biopsy and immunohistochemical results were compatible with the finding of LCH. The patient evolved with polyuria, polydipsia, and nocturia, confirming the presence of diabetes insipidus and panhypopituitarism through hormonal studies. Magnetic resonance imaging (MRI) of the brain shows a hypothalamic neoplasm with infundibular involvement and an image suggestive of a pituitary granuloma. The treatment consisted of maxillobuccofacial defocusing, hormonal supplementation, chemotherapy, and radiotherapy with favorable evolution.
