Xanthogranulomas of the choroids plexus (XG) are benign tumours of debatable etiology which become rarely symptomatic. Only few cases have been studied with MRI. A new case of xanthogranuloma of the third ventricle showing unusual features in the CT and MRI studies in a 47-year-old man with a 2-month history of gait and urinary disturbances and cognitive impairment is reported. The literature c...
Necrobiotic xanthogranuloma is a rare, idiopathic, and chronic systemic granulomatous disorder that is usually associated with paraproteinemia of the immunoglobulin (Ig)G kappa (κ) type. It is clinically characterized by yellowish red-to-brown indurated often ulcerating nodules or plaques that usually involve the periorbital regions of the elderly.

We report the case of a 44-year-old woman who presented with vaginal bleeding. Vaginal examination and colposcopy showed a tumor on the anterior lip of the cervix. Trans-vaginal sonography revealed a thickened endometrium with accentuated vascularization. Samples from the tumor and endometrium were collected by byopsic curettage. Histopathologic examination showed atypical hyperplasia of the en...
Juvenile xanthogranuloma (JXG) is a rare histiocytic disorder that is usually benign and self-limiting. We present a case of atypical, aggressive JXG harboring a novel mitogen-activated protein kinase (MAPK) pathway mutation in the MAPK1 gene, which encodes mitogen-activated protein kinase 1 or extracellular signal-regulated 2 (ERK2). Our analysis revealed that the mutation results in constitut...

The tumor was treated with topical steroids on suspicion of a juvenile xanthogranuloma; later, it grew slightly and a secondary glaucoma developed. Histopathological examination of the resected tumor showed lacr...
