BRAF V600E mutation in Juvenile Xanthogranuloma family neoplasms of the central nervous system (CNS-JXG): a revised diagnostic algorithm to include pediatric Erdheim-Chester disease

Acta Neuropathologica Communications, 2019
The family of juvenile xanthogranuloma family neoplasms (JXG) with ERK-pathway mutations are now classified within the “L” (Langerhans) group, which includes Langerhans cell histiocytosis (LCH) and Erdheim Chester disease (ECD).

Intraocular Metastasis: Differential Diagnosis and Management

Clinical &Experimental Ophthalmology, Volume 54, Issue 3, Page 382-397, April 2026.
ABSTRACT Intraocular metastases represent the most common type of malignant intraocular tumour in adults. These commonly affect the choroid but can also involve the iris, ciliary body, retina, vitreous, optic disc or lens. Breast and lung cancer are the most common origins of intraocular metastases.

Adult-Onset Asthma with Periocular Xanthogranuloma (AAPOX), a Variant of Periorbital Xanthogranulomatous Disease: An Uncommon Entity

Indian Dermatology Online Journal, 2020
Adult orbital xanthogranulomatous disease (AOXGD) is a rare granulomatous disorder. Adult-onset asthma with periocular xanthogranuloma (AAPOX) which is a subtype of AOXGD is very rare and a realtively unknown entity among dermatologists.

Robustness of a convolutional neural network trained on dermoscopic images and challenged with close‐up images

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 24, Issue 4, Page 504-513, April 2026.
Summary Background and Objectives Deep learning‐convolutional neural networks (DL‐CNNs) have demonstrated high diagnostic accuracy within the domain of dermoscopy. However, many clinical settings lack dermoscopic devices, requiring reliance on close‐up images. This study evaluates the robustness of a DL‐CNN trained on dermoscopic images when challenged
