Juvenile xanthogranuloma (JXG) is a benign Non-langerhancian histiocytic proliferation. Herein, we report the case of a 17-month-old infant, who presented with two months history of a diffuse asymptomatic papular eruption, made of orange papules onthe face, trunk and limbs. A skin biopsy performed, showed a Non-langerhansian histiocytosis type juvenile xanthogranuloma. Through this case report, we highlight the importance of knowing this rare entity that may be diagnosed easily in typical cases, but may be more difficult to diagnose in unusual variants.
Juvenile xanthogranuloma; Non-langerhancian histiocytosis
Juvenile xanthogranuloma (JXG) is a benign Non-langerhancian histiocytic proliferation of uncertain histogenesis which usually resolves spontaneously. Herein, we report a new case of diffuse juvenile xanthogranuloma.
A 17-month-old infant was presented with two months history of a diffuse asymptomatic popular eruption. The dermatological examination found orange papules well limited, firm, infiltrated, rounded to oval, 0.5 to 2 cm diameter, located in the face, trunk, upper and lower limbs (Figures 1 and 2). The immuno-histological study showed a Non-langerhansian histiocytosis type juvenile xanthogranuloma CD68+, PS100+, CD1a- (Figure 3). Biological and morphological explorations did not reveal a systemic localization. No treatment was administered because of the spontaneously resolving nature of this dermatosis. The evolution was marked by the disappearance of skin lesions after 3 years of follow-up.
JXG is the most frequent Non-langerhancian histiocytosis (NLH). It usually occurs in infants and children in 80% of cases before the age of 2 years . The lesions preferentially sit at the level of the upper part of the body but may also appear at the limbs. It is characterized by a single papule or a single yellow-orange nodule . The JXG is rarely multiple which makes the originality of our observation. We should distinguish between the micro-nodular form which is the most frequent, and the macro nodular form that could have a particular risk of systemic involvement (lung, bones, kidneys, testicles, pericardium, eye, etc.).
The diagnosis is histological, showing a dense dermal infiltration of epithelioid cells with vacuolated and foamy histiocytes S100-, CD1-, CD68+ and touton cells . The JXG prognosis is generally benign with self-regression in a few months to a few years . Therapeutic abstention may be proposed. For non-regressive forms, treatment is not well codified due to the scarcity of the different entities.
In summary, our observation illustrates a clinically atypical observation of JXG by the multi-lesional and multifocal nature of lesions. It illustrates also the difficulties of classifying benign forms of NLH, because of the existence of forms of passage between different entities.
