Presentation
Its most common site of extracutaneous presentation is the eyes. [pathologyoutlines.com]
Although this benign disorder typically presents with a favorable clinical outcome, the unusual presentation as an intratesticular lesion can lead to diagnostic challenges. [ncbi.nlm.nih.gov]
Ocular manifestations usually present in the form of iris lesions with secondary hyphema and glaucoma, but juvenile xanthogranuloma may also present as a corneoscleral limbal mass. [thedoctorsdoctor.com]

In infancy, there is a male predominance in a ratio of 1.5:1, with a tendency to spontaneous regression, which may result in atrophy and hyperpigmentation.1,3,4 Although the term juvenile xanthogranuloma is used, adult cases can occur, especially in patients [anaisdedermatologia.org.br]
It is worth to note that regression is capable of generating atrophy and hyperpigmentation.1 Dermoscopy is useful in assisting the diagnosis, since this condition has a typical pattern, characterized by an orange color background – described as the "setting [surgicalcosmetic.org.br]
Histopathological examination of JXG with whitish area revealed dermal fibrous tissue, while the pigment network represents hyperpigmentation in the basement of the epidermis. Figure 1. [frontiersin.org]
Residual atrophy, anetoderma, or hyperpigmentation are not uncommon after lesions resolve. Expected results of diagnostic studies There is no dyslipidema associated with JXGs. There are no known associated laboratory anomalies. [dermatologyadvisor.com]

We report a rare case of juvenile xanthogranuloma in a 16-year-old girl who presented with a neck mass and left-sided ptosis 2.5 months previously. [ncbi.nlm.nih.gov]

Workup
These data highlight the importance of identifying specific MAPK pathway alterations as part of the diagnostic workup for patients with histiocytic disorders rather than initiating empiric treatment with MEK inhibitors. [ncbi.nlm.nih.gov]
In Neurofibromatosis 1, JXGs are also more prevalent so workup for this genetic disease may be initiated with the discovery of JXG. [perridermatology.com]
Results from a medical workup, which included computed tomography of the orbits, were unremarkable. Evaluation of the patient's skin revealed several yellow-orange to yellow-brown pigmented nodular lesions on the face and scalp. [jamanetwork.com]
Laboratory tests and autoimmune workup were completed in 7 patients. [docksci.com]
However, this case provides an example in which MEK inhibition would presumably be ineffective, supporting a strategy of identifying the specific MAPK pathway alterations in each case as part of the diagnostic workup for patients with histiocytic disorders [oncotarget.com]
