Juvenile Xanthogranuloma (JXG) is a benign proliferative disorder of non-Langerhans histiocytes, occurring in vast majority of cases as multiple, selflimited, cutaneous lesions of children in the first two decades of life [1]. Extracutaneous manifestations of JXG are uncommon, and isolated JXG involving the spinal column is extremely rare [2]. We hereby report the clinicopathological features o...

Exostosis, osteoma, and adenoma are the most commonly encountered benign lesions in the external auditory canal. Herein, we report a case of the mass arising from the external auditory canal in a 24-year-old Japanese man. CT revealed the soft tissue mass without bony erosion, and MRI revealed that the mass showed a homogenous, iso signal intensity on a both T1- and T2-weighted image, suggesting...

Xanthogranulomas of the choroid plexus are discovered incidentally on autopsy in 1.6 to 7% of cases, and are typically found in the lateral ventricles. Very rarely, however, they can become symptomatic because of obstruction of the ventricular system, and these tend to be found in the third ventricle. There has only been one published case of fourth ventricle choroid plexus xanthogranuloma. We ...

purpose: to report an extremely rare presentation of isolated orbital xanthogranuloma with no systemic disease, nor dermatologic manifestation. case report: the patient was a 45-year-old man complaining of a mass lesion in the superior and inferior eyelids of his right eye; the lesions had been enlarging slowly and painlessly since 5 years before. other examinations (including skin, heart, etc....

Generalized granuloma annulare (GGA) is a rare benign granulomatous dermatosis characterized by disseminated necrobiotic dermal papules. Histologically, it presents as a lymphohistiocytic granuloma associated with varying degrees of connective tissue degeneration. It usually occurs in adults and rarely affects infants. Herein, we report an interesting case of GGA which occurred in a 3 month-old...

ISSN 0001-5555 Juvenile xanthogranuloma (JXG) is a non-Langerhans histiocytosis occurring predominantly in infancy and early childhood. Resolution usually occurs over a period of months to several years, and it is rare for the condition to persist beyond late childhood (1). The symmetrical gian...
