Summary-A case of congenital infiltrating congenital cytomegalovirus infection.
lipomatosis
Case report A male child, G.L., presented at birth with a significant subcutaneous mass in the left cheek, producing marked facial asymmetry. There were no relevant episodes during the pregnancy, such as infectious disease, drug abuse or exposure to teratogenic agents. At birth, mild jaundice and slight hepatomegaly were noted. Laboratory data were as follows: total bilirubin 4.56 mg% (direct 1.95, indirect 2.61), SGOT 65 W/l, SGPT 28 IUjl, gamma GT 125 IUjl, alkaline phosphatase 124 IUjl. The clinical and laboratory abnormalities regressed spontaneously to normal by 3 months. The lesion was covered by skin of normal colour and texture; it waselastic, non-tender, with ill-defined borders (Fig. l), and there were no murmurs or palpable thrills. The tumour steadily enlarged and at the age of 4 months the patient was admitted to the paediatric division of our hospital following convulsions. EEG revealed slow and widespread high voltage anomalies of the left hemisphere, of epileptic pattern. These findings and the symptoms improved after the start of anticonvulsant drug treatment. X-rays of the skull revealed asymmetry of the cranial vault which presented greater convexity on the left. No signs of intracranial hypertension or pathological calcification were detected. CT scans (Fig. 2) confirmed that the left cerebral hemisphere was significantly larger than the right, associated with overdevelopment of the left hemicranial vault. The left lateral ventricle was enlarged. A generalised hypodensity of the white matter of the right hemisphere was detected. Also evident was the asymmetry of the soft tissues of the face but no abnormalities were seen within them. A biopsy of the subcutaneous mass reported the presence of normal adipose tissue only. Because of the increase in facial asymmetry, surgery was carried out at the age of 5 months. Through a rhytidectomy incision and with the help of an electrostimulator to preserve the facial nerve, the non-encapsulated adipose mass was excised as radically as possible. 124

Histological examination (Fig. 3) revealed the presence of parotid gland tissue, and large epithelial cells with intracellular and intranuclear inclusions typical of cytomegalovirus infection were present in the intralobular ducts. A search for specific anti-CMV antibodies (IgG and IgM) was also positive. After surgery the residual mass showed no tendency to recur but the patient failed to thrive and died at the age of 20 months of a pulmonary infection.

Infiltrating congenital lipomatosis of the face is a rare but well defined clinical entity (Slavin et al., 1983; Baker, 1984). More frequently, it first appears later in life and in other parts of the body [80x of lipomatoses affect the lower limbs (Regan et al., 1946; Gonzale-Crussi et al., 1966)]. Lipomatosis of the face is localised in the cheek and physical examination reveals a poorly defined elastic tumour that may reach a remarkable size, with overlying skin of normal colour and texture. Microscopic examination reveals non-capsulated fatty tissue formed by mature adipocytes infiltrating the neighbouring structures, such as peripheral nerves, salivary glands (parotid), muscles and vessels, thus minimising the possibility of a radical excision. The presence of mature adipocytes and the absence of lipoblastic proliferation, pleomorph-

Although they are benign, treatment of these neoplasms is difficult as radical excision often implies the sacrifice of important anatomical structures. This explains the high recurrence rates, estimated at 50-60x (Dionne and Seemayer, 1974). Congenital CMV infection is transmitted transplacentally. It is a common disease [about 2% of newborns are immunologically positive (Krugman and Katz, 1981)], but fortunately in only 5% of positive subjects do clinically evident lesions arise. Symptoms frequently do not arise until several months after birth; these can vary to a great degree and can involve any anatomical area. However, the central nervous system is by far the most frequent target, with microcephaly, enlarged ventricles, convulsions, spasticity etc. Other clinical findings such as hepatosplenomegaly, jaundice, chorioretinitis, coagulation defects and skin rashes are common. Localisation in the salivary glands (parotid in particular) is typical. In such cases intranuclear and cytoplasmatic inclusion bodies, which can at times be identified in other parts of the body also, are diagnostic. In this case report most of the typical symptoms of a congenital CMV infection were present : jaundice, hepatomegaly, complex neurological alterations, and death following a respiratory infection (these patients are highly susceptible to infections). The diagnosis was confirmed by histology and CMV positive serology. Hanshaw (1970) has listed a large series of abnormalities associated with CMV congenital infection, among which lipomas are included. However, we have not traced reports in the literature relating a congenital infiltrating lipomatosis of the face to a CMV infection. The finding of glandular tissue within the lipomatosis, with the typical CMV inclusions, confirmed involvement of the region with the viral
