A 5-month-old boy had erythematous nodules over the left side of his trunk with a segmental arrangement since birth. Histopathologic examination revealed sheets of foamy histiocytes infiltrating the dermis and subcutaneous fat, admixed with multinucleated giant cells and lymphocytes, making this an unusual case of juvenile xanthogranuloma appearing in a segmental distribution.
Juvenile xanthogranuloma is a benign cutaneous growth presenting as papules or nodules. It is characterized by an intradermal collection of lipid-laden macrophages and varying degrees of fibroblastic proliferation. We have recently observed two patients with xanthogranulomas: one was found to have a papular type and the second patient had multiple nodular growths. We present these cases, which should be considered in the differential diagnosis of skin nodules.
A 3-month-old female patient with a giant ulcerated nodule over the back since birth was diagnosed as congenital giant juvenile xanthogranuloma (JXG) based on clinical and histopathological examination. Congenital giant JXG with ulceration at birth is a rare presentation of JXG and commonly misdiagnosed. This case emphasizes the importance of being aware of the myriad presentations of JXG in order to make a correct diagnosis and avoid unnecessary investigations or treatment.
Juvenile xanthogranuloma (JXG) is an uncommon condition affecting the eye. We herein report a rare case of eyelid swelling in paediatric age group. A three-year-old Malay boy presented with chronic painless left upper eyelid mass which did not resolve with topical steroid. Clinically, the mass was a non-tender and firm nodular swelling which located at the lateral 1/3 of the left upper lid. Total excisional biopsy of the swelling was done and histopathological findings were consistent with JXG. The systemic associations and the treatment options for ocular JXG are discussed.
