Giant congenital juvenile
xanthogranuloma
CASE REPORT
A 1-month-old otherwise healthy girl was referred to our clinic
for evaluation of a congenital asymptomatic lesion on the face.
Upon physical exam, a firm, sharply marginated, infiltrative,
yellowish plaque measuring 6×4 cms with peau d’orange
surface was evident on the right mandibular region (figure 1).
A 4 mm punch biopsy was performed and histological exam
revealed a diffuse infiltrate of non-foamy mononuclear histio-
cytes with scattered eosinophils within the papillary dermis, and
a scarce amount of Touton cells. Immunohistochemistry was
positive for the histiocytic marker, CD68, and negative for
CD1a and S-100 protein, indicating an origin of
non-Langerhans cells. On this basis, we confirmed the clinical
suspicion of giant congenital juvenile xanthogranuloma ( JXG).
JXG is the most common form of non-Langerhans cell histio-
cytosis characterised by purple-red to yellow-brown papules or
nodules, usually measuring less than 10 mm in diameter.
Lesions larger than 20 mm in diameter are extremely rare and
classified as giant JXG. The eye is the most common extracuta-
neous site affected, but virtually any organ can be involved.1–4
In our patient, systemic examinations revealed no abnormalities,
without any lymphadenopathy, hepatosplenomegaly or ophthal-
mological involvement. In the cases of cutaneous lesions
without visceral involvement, the prognosis is excellent, and a
‘wait-and-see’ strategy is recommended. Spontaneous regression
usually occurs within 6 months to 3 years (figure 2).5
The differ-
ential diagnosis of giant JXG includes mastocytoma, rhabdo-
myosarcoma, giant cell fibroblastoma, juvenile nodular fasciitis,
dermatofibrosarcoma protuberans and other soft tissue neo-
plasms.4
Correct diagnosis is important to avoid unnecessary
invasive procedures or aggressive treatments.
