RESUMEN
Invasive pulmonary mucormycosis and aspergillosis are rare, life-threatening fungal infections. Most documented cases have been reported in non-cirrhotic patients with diabetes mellitus, neutropenia, or treatment with corticosteroids. The prevalence of each infection is low among patients with hepatic cirrhosis. We report the first likely case of combined invasive pulmonary mucormycosis and aspergillosis in a male with decompensated hepatic cirrhosis. This report also highlights the first non-diabetic case of invasive pulmonary mucormycosis with decompensated hepatic cirrhosis.
RESUMEN
Langerhans cell histiocytosis (LCH) is a rare syndrome characterized by unifocal, multifocal unisystem, or disseminated/multi-system disease that commonly involves the bone, skin, lymph nodes, pituitary, or sometimes lung (almost exclusively in smokers) causing a variety of symptoms from rashes and bone lesions to diabetes insipidus or pulmonary infiltrates. We present a previously unreported case of gastrointestinal LCH as well as a novel characteristic lesion affecting the colon of a young woman who presented with signs and symptoms mimicking acute on chronic appendicitis. Immunohistochemical analysis of appendectomy specimen and nodular specimens on colonoscopy demonstrated S-100, CD1a, and langerin reactivity. The patient underwent systemic chemotherapy with cytarabine and demonstrated excellent response to therapy.
