An unusual case of intertrigo in an adult caused by purely cutaneous Langerhans cell histiocytosis [PDF]

, 2016
We report a case of persistent intertrigo in an adult, eventually diagnosed as cutaneous Langerhans cell histiocytosis (LCH). It is known that LCH has a predilection for intertriginous areas, however purely cutaneous disease as in our case, is uncommon ...

Cutaneous Rosai‐Dorfman Disease With MAP2K1 Mutation Treated With Encorafenib and Binimetinib

JEADV Clinical Practice, EarlyView.
ABSTRACT Rosai‐Dorfman disease (RDD) is a rare histiocytic disorder with unifocal to multisystemic involvement. Activating mutations in the MAPK/ERK pathway can occur in up to 50% of RDD cases. We report a case of cutaneous RDD (C‐RDD) with facial and truncal lesions harboring an activating MAP2K1 (MEK1) mutation that showed a complete response to a ...

Tattoo Inflammation With Uveitis: From Recognition to Definition

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Tattoo inflammation with uveitis (TIU) is increasingly recognised but growing case numbers have revealed substantial heterogeneity. Patients currently classified as TIU appear to include those with overt or evolving systemic sarcoidosis as well as those with isolated, pigment‐associated ocular inflammation.

Urticating histiocytosis: A mast cell-rich variant of histiocytosis X

, 1986
Histiocytosis X and mastocytosis are proliferative processes that may have similar cutaneous manifestations. However, a positive Darier's sign (urtication on stroking of the lesion) is thought to reliably distinguish between these two diseases.

Langerhans cell histiocytosis presented as bilateral otitis media with effusion, a rare case report

Caspian Journal of Internal Medicine, 2023
Background: Langerhans cell histiocytosis (LCH) or histiocytosis X is considered as a rare disease that may have effect on multiple organs. The initial presentation of LCH is varied. The signs and symptoms of otologic histiocytosis can be the same as the

Disseminated Xanthogranuloma Harboring a GAB2::BRAF Fusion and MITF Pathogenic Variant Successfully Treated With Cobimetinib: A Rare Case Report

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Several activating mutations and gene fusions involving the mitogen‐activated protein kinase (MAPK) pathway have appeared in the literature regarding histiocytic neoplasms. We identified a GAB2::BRAF fusion in a cutaneous lesion of a 36‐year‐old male who developed central diabetes insipidus and reddish‐pink grouped papules on the bilateral ...

Pediatric Langerhans Cell Histiocytosis Presenting With Bilateral Parotid Gland Swelling and Cystic Lung Disease: A Case Report and Literature Review

Pediatric Dermatology, EarlyView.
ABSTRACT Langerhans cell histiocytosis (LCH) is a neoplastic process originating from immature myeloid precursor cells. In this report, we describe a case of a 17‐month‐old with scaling of the scalp and swelling of the bilateral parotid glands who developed acute respiratory distress.

Oral manifestion of Langerhans cell histiocytosis mimicking inflammation

Indian Journal of Dental Research, 2014
Langerhans cell histiocytosis (LCH) is a rare idiopathic disease characterized by the clonal proliferation of Langerhans cells. LCH affects five children per million population. The peak incidence is from 1 to 4 years of age.

Histiocytes: Multifaceted Regulators of Health and Disease

Veterinary Clinical Pathology, EarlyView.
ABSTRACT The mononuclear phagocyte system encompasses macrophages, dendritic cells (DCs), and monocytes. Tissue‐resident macrophages and dendritic cells arise during embryogenesis and are replenished either through self‐renewal or by monocytes during inflammation.
