Introduction: Erdheim-Chester disease (ECD) is a rare non-Langerhans histiocytic multisystem disorder, deriving from mononuclear phagocytic cells. It is notoriously challenging to diagnose. Here we present a case of a patient with multisystem ECD.

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis typically featuring lower extremity osteosclerosis (96%) from Langerin-negative histiocytes with fibrosis. Central nervous system (CNS)-only disease is extremely rare, and particularly difficult to diagnose and manage. Neurologic complaints may be refractory to systemic therapy (ST), and the role of radiation therapy (RT) is undefined.

Generalized eruptive histiocytoma (GEH) is a very rare benign disorder belonging to the group of non-Langerhans cell histiocytosis (non-LCH). GEH is characterized by a nearly uniform infiltrate of histiocytes with classic immunological phenotype (CD68+, S-100- and CD1a-). Prominent eosinophilic infiltration and S100-positive histiocytes are rarely associated in GEH.

Rosai Dorfman disease is a rare histiocytic disorder of over-production of non-Langerhans histiocytes, which typically manifests with massive lymphadenopathy and sinonasal involvement. We report a rare case of systemic and disseminated craniospinal Rosai Dorfman disease with intraparenchymal and leptomeningeal involvement, but no sinus or dural-based disease. The diagnosis was established by biopsy of a hypothalamic mass.

Necrobiotic xanthogranuloma is a rare type of non-Langerhans histiocytosis, whose main clinical features are the development of red-brown, purplish or yellowish skin papules and nodules, which evolve by forming infiltrated plaques. The periorbital region is the most commonly affected site. Some cases have lesions on the torso or extremities, with no facial involvement.
