Histiocytosis X (Langerhan’s cell granulomatosis) is a disease of unknown aetiology, but viral origin has been implicated.1 It is a clinicopathologic entitycharacterized by proliferation of Langerhan’s cell (which are not primarily phagocytic) in an appropriate milieu ...

Local ALK-Positive Histiocytosis With Unusual Morphology and Novel TRIM33-ALK Gene Fusion
International Journal of Surgical Pathology, 2020ALK-positive histiocytosis was first described in 2008 as a systemic histiocytic disorder involving young infants and neonates. Subsequently, cases of local ALK-positive histiocytosis as well as clinical presentation in adult patients have been ...

Histiocytosis X is characterized by a proliferation of cytologically benign histiocytes and occurs in a severe form (type 1) with a short course and poor prognosis and a milder form (type 2) with a protracted course and favorable prognosis. Otolaryngologists will encounter the type 2 form of the disease and must include it in the differential diagnosis

Clinical and Experimental Dermatology, 1988Summary A 48-year-old Lebanese man presented with a 2-year history of painless papules and nodules of the skin without any systematic involvement, lymphadenopathy, serum electrophoresis disturbance, leukocytosis or elevated erythrocyte sedimentation rate (ESR).

AbstractThree patients with multiple skin nodules on the trunk and extremities showed hyperpyrexia, lymphadenopathy, pancytopenia, abnormal liver function, and terminal hemorrhagic diathesis. Histologically, the deep dermis and subcutaneous fat contained dense infiltrates of atypical erythropagocytic histiocytes and lymphoid cells.

To clarify salient issues pertaining to histiocytosis X--a syndrome that includes Letterer-Siwe disease, Hand-Schuller-Christian disease, and eosinophilic granuloma--the authors review the epidemiologic data and the histologic, morphologic, and clinical bases for diagnosis and prognosis. Histiocytes are defined and their possible histogenesis outlined,

Malignant histiocytosis, also known as histiocytic medullary reticulosis, is a rare neoplasm of malignant histiocytes. Clinical findings include fever, weight loss, hepatosplenomegaly, lymphadenopathy, anemia, thrombocytopenia, and a rapidly worsening course.

Otolaryngologic Clinics of North America, 1982
Histiocytosis X may be isolated or generalized in its clinical involvement. Spontaneous resolution may occur, although progression to diffuse systemic disease has also been found. The disease is believed to originate from the mononuclear phagocytic series of cells, although the reason for this activation remains unknown. A possible local reaction to an
