Indeterminate cell histiocytosis (ICH) is a rare proliferative disorder, in which the predominant cells share morphologic and immunophenotypic features from both Langerhans and non-Langerhans cell histiocytosis. We describe a 62-year-old man presenting a 2-month history of firm nodular lesions on the upper lip. Histopathology, immunohistochemical, and ultrastructural analysis showed typical fin...

langerhans cell histiocytosis (lch) is the most common type of childhood histiocytic disorder with an incidence of 0.2 to 1 per 100,000 children under the age of 15 years (1). the clinical picture of lch varies from single system (s-s)bone or skin disease to multi-system disease (m-s) (2). we report a neonate with disseminated papulonodular eruption containing mononuclear cd1a and s100 positive...

purpose : fine needle aspiration (fna) cytologic findings of langerhans cell histiocytosis (lch) have been well described, but using this method in the diagnosis of orbital lesions is a recent experience. we hereby report two cases of orbital bone lch diagnosed by fna that later was confirmed by routine h&e; histopathology and immunohistochemistry (ihc) methods. case reports : the first case wa...

histiocytosis of langerhans cells (class 1 histiocytosis) consists of a range of clinical manifestations, including bone eosinophilic granuloma, hand-schüller-christian syndrome, and letterer-siwe disease. these syndromes represent a spectrum of severity and prognosis of an underlying disorder which is usually sporadic. this report describes three cases in one family, who developed the disease ...

conclusions pericardial effusion was a rare finding in this case of langerhans cell histiocytosis. pericardial effusion in langerhans cell histiocytosis, which is an unusual presentation, should be considered when the patient experiences respiratory distress. introduction langerhans cell histiocytosis (lch) is a proliferative disorder of histiocytes in multiple organs. langerhans cell histiocyt...
