Unlikely presentation masks case of early juvenile xanthogranuloma

Washington D.C. - Juvenile Xanthogranuloma (JXG) is a rare histiocytic proliferation of uncertain histogenesis usually found in the cephalic region and more common in males less than one year of age. So when an 11-day old female neonate presented to Wake Forest University Baptist Medical center with a firm, immobile, non-pulsatile, pink-red nodule and telangiectases localized to the right groin, JXG was not initially suspected. However, as part of the initial workup, a confirmatory biopsy revealed the diagnosis.
