Abstract
Juvenile xanthogranuloma (JXG) is a member of the non-Langerhans cell group of histiocytic proliferative disorders. It is a benign cutaneous fibrohistiocytic lesion most often affecting infants and young children. Juvenile xanthogranuloma is rare in adults, in whom the peak incidence is in the late twenties to early thirties and most adult patients have solitary lesions. A 55 year-old male presented with multiple disseminated cutaneous eruption that started almost a decade ago on the trunk and 7 years ago on the face. The lesions were asymptomatic and followed a slowly progressive course. Cutaneous examination revealed numerous well demarcated, firm, rubbery brownish yellow non tender papulo-nodular lesions of different sizes over the face, neck, and front of the trunk. There were few lesions on the upper extremities, predominantly over the elbows. A differential diagnosis of eruptive xanthoma, xanthogranuloma, histiocytosis and neurofibroma was considered. Skin biopsies were taken and sent for histopathological examination. The diagnosis of multiple xanthogranulomas in an adult was made based on the clinical picture and histopathological findings. We describe a classic, rather an unusual clinical presentation in an adult highlighting the wide variation in presentation and the importance of considering this entity in the differential diagnosis of multiple benign eruptive lesions in an adult.
