A novel GAB2::BRAF fusion in cutaneous non‐Langerhans‐cell histiocytosis with systemic involvement

Journal of cutaneous pathology, 2022
Several mutations and gene fusions involved in the mitogen‐activated protein kinase (MAPK) pathway have been reported in histiocytic neoplasms including Langerhans cell histiocytosis and non‐Langerhans‐cell histiocytosis (NLCH).

An unusual case of non-Langerhans cell histiocytosis

Journal of the American Academy of Dermatology, 1994
A 28-month-old boy had firm, red nodules for 4 months that were mostly localized to the face. The eruption was preceded by conjunctivitis, eyelid edema, and swelling of the root of the nose. He also had dyspnea, anisocoria with areflexia, swelling of the parotid glands, and hepatosplenomegaly. A bone marrow aspirate showed 25% eosinophils.

Non Langerhans Cell Histiocytosis of the Rectum: Case Report and Review of the Literature

Japanese Journal of Gastroenterology and Hepatology, 2022
Histiocytosis is a condition resulting from the abnormal proliferation of dentritic cells of the mononuclear phagocytic system. Previously classified as Langerhans cell histiocytosis and non-Langerhans cell histiocytosis, and recently into 5 categories (L, C, R, M and H), it can be localized to an organ or have a systemic manifestation, affecting most ...

New entity of an isolated pulmonary non-Langerhans cell histiocytosis

European Respiratory Journal, 2013
Background: Histiocytic disorders are rare, heterogeneous diseases with abnormal tissue infiltration by histiocytes. So far, pulmonary manifestation in Non-Langerhans cell histiocytoses (NLCH) occurred only as a part of a systemic disease. Case: A 37 year old male stonesculptor suffered from progressive dyspnea and thoracic tightness.

Lymphocyte sub-populations and non-Langerhans’ cell monocytoid cells in pulmonary Langerhans’ cell histiocytosis

Pathology - Research and Practice, 2008
Pulmonary Langerhans' cell histiocytosis (PLCH) is a disease characterized by the occurrence of complex fibro-cellular interstitial lesions dominated by Langerhans' cells (LC), which occurs predominantly in young adult smokers. We undertook this retrospective study to better define the lymphohistiocytic cell populations in PLCH in order to obtain a ...

[Acquired regressive cutaneous non-Langerhans-cell histiocytosis in an infant].

Annales de dermatologie et de venereologie, 1998
Cutaneous histiocytosis of childhood often regresses spontaneously without treatment. In some cases however, it is difficult to differentiate aggressive forms and electron microscopy and immunohistochemistry can be a valuable help. We report a case of cutaneous histiocytosis in a child which illustrates the difficulties encountered in the ...

Non-langerhans Cell Histiocytosis-Including Erdheim-Chester Disease- and the Lung

2014
Erdheim-Chester disease (ECD) is a rare form of non–Langerhans’ cell histiocytosis that may present with pulmonary involvement. The disease was first described as the “lipoid granulomatose” in 1930. Between then and 2013, more than 500 cases have been reported.
