Abstract. The purpose of this article is to present a case of juvenile xanthogranuloma with pulmonary, retroperitoneal and splenic involvement. The similar echographic pattern of the cutaneous and visceral lesions was very helpful in o r d e r to suggest the correct diagnosis.

Juvenile x a n t h o g r a n u l o m a (JX) is a normolipemic, self-limited histiocytosis occurring in childhood and infancy, and is characterized by cutaneous and ocular xanthomas. Visceral involvement is rare yet can occur in several locations. We r e p o r t a case of a n e w b o r n infant with juvenile x a n t h o g r a n u l o m a involving the lungs, the r e t r o p e r i t o n e u m and the spleen and present the results of a revision of previously r e p o r t e d cases.

Case report

tion, a hypoechoic solid paraduodenal mass, 2.5 x 2 cm in diameter, with a hypoechoic central zone, was detected (Fig. 2 a). The liver was normal in size and echogenicity. The sonographic features of the subcutaneous nodule were similar to those of the retroperitoneal lesion (Fig. 2 b). Thoraco-abdominal CT disclosed three pulmonary nodules on the right side and an abdominal paraduodenal rounded mass. This mass was soft-tissue density with several central hyperdense loci. The spleen was enlarged and showed many scattered small hypodense nodules, which were better seen following the administration of i.v. contrast material (Fig.3). The right axillary nodule was surgically removed. Pathological examination revealed a well-defined yellowish mass, with peripheral fibroblasts surrounding a central zone with multiple xanthomatous cells and Touton-type giant cells. These features confirmed the diagnosis of JX. The patient received no treatment, and in a follow-up exam performed four months later, all his gluteal nodes had considerably decreased in size. On a repeated US the spleen was normal. The retroperitoneal mass, though smaller, persisted.

Discussion Juvenile x a n t h o g r a n u l o m a is a benign condition included in the b r o a d category of histiocytic diseases. It is characterized by cutaneous and ocular xanthomatous lesions, with the latter being less common. The skin lesions are usually quite obvious and are considered the

A 10-day-old newborn girl was referred to our hospital for evaluation of several subcutaneous nodules and splenomegaly. There were multiple hard right axillary and left gluteal nodules, not adherent to deep planes and which measured from 0.5 to 2 cm. The spleen was moderately enlarged. Routine laboratory data were normal. Skeletal X-ray survey was also normal. Chest X-rayshoweda i cmpulmonary nodule in the right lower lobe (Fig.l).

cence. They can be single or multiple and are more frequently located in the head and neck [1, 2]. Size varies from 1 mm to 5 cm; they can be macular or nodular in shape and reddish-brown in color which progresses to yellow. This entity is also characterized by ocular involvement, with the iris being the most frequent location [3]. Visceral involvement is rare but when it occurs, it is always associated with cutaneous lesions. Pericardium, testes, lymph nodes, liver, kidney and lungs are the extracutaneous locations described in this illness. Gilbert and Parker reported the first case with renal involvement shown by US and CT [4]. Sonographically the renal mass had mixed echogenicity. CT showed an isodense renal mass which following the administration of i. v. contrast material became hypodense in relation to the normal renal parenchyma. On chest X-rays, all lesions were nodular and well-defined, and ranged from 1 to 2.5 cm in diameter [1, 5, 6]. Calcifications have never been observed. Diard et al. presented a case with pulmonary, extrapleural and hepatic lesions [6]. A n echogenic nodule in the liver was detected by US and was the first reported case with hepatic involvement studied by US. The diagnosis of JX is established by biopsy of the cutaneous lesion.

Differential diagnosis should include histiocytosis X and systemic dyslipidoses. Bone lesions do not occur in xanthogranulomatosis. On the other hand elevated serum lipids and cholesterollevels are the hallmark of the systemic dyslipidoses. However, biopsy of the cutaneous lesions will be mandatory to establish diagnosis. The prognosis in JX is excellent. Most cutaneous and visceral lesions regress spontaneously without treatment [1, 3, 5, 6].
