Histiocitosis de Langerhans y panhipopituitarismo en adulto. Reporte de caso

Abstract

Langerhans histiocytosis and panhypopituitarism in adults. Case reportLangerhans-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.
