Encephalocraniocutaneous lipomatosis (ECCL) is a rare, sporadic congenital neurocutaneous disorder that characteristically involves ectomesodermal tissues, such as skin, eyes, and central nervous system. A 3-day-old girl presented with swelling in her right eye since birth. Ocular examination of the right eye showed hypertrophy of bulbar conjunctiva with limbal dermoid, clouding of cornea, and atypical upper eyelid coloboma. The left eye showed conjunctival congestion and corneal vascularization. Dermatological examination showed alopecia, nevus psiloliparus, focal dermal hypoplasia on forehead, multiple focal aplastic lesions on the scalp, skin tag at canthus, and lipoma in the fronto-temporal region. Imaging revealed calcification of the right globe, hydrocephalus, agenesis of corpus callosum, multiple intracranial cysts, calcification, and lipomas. The constellation of these clinical and the imaging findings led to a diagnosis of encephalocraniocutaneous lipomatosis. This case report and review of the literature is presented to provide a synopsis of problems likely to be encountered by an ophthalmologist who treats patients with ECCL. Keywords: Haberland syndrome, oculocerebrocutaneous syndrome, encephalocraniocutaneous lipomatosis syndrome, neurocutaneous syndrome, Delleman-Oorthuys syndrome, Fishman syndrome

Encephalocraniocutaneous lipomatosis (ECCL) formerly known as Haberland or Fishman syndrome is a rare, sporadic congenital neurocutaneous disorder that characteristically involves ectomesodermal tissues, such as skin, eyes, and central nervous system (CNS). [1],[2]
ECCL has classical triad of cutaneous abnormalities (nevus psiloliparus, subcutaneous lipoma in the fronto-temporal region, focal dermal hypoplasia or aplasia, small nodular tag on the eyelid or at outer canthal area), ocular abnormalities (choristomas, colobomas, corneal or anterior chamber abnormalities, and globe calcification), and CNS abnormalities (intracranial or intraspinal lipoma, abnormal intracranial vessels, complete or partial atrophy of a hemisphere, asymmetrically dilated ventricles or hydrocephalus, arachnoid cyst, porencephalic cyst, and calcification). [1] Here, a unique and rare case of a 3-day-old girl with diagnosis of ECCL is being reported. This case report and review of literature is presented to provide a synopsis of the problems likely to be encountered by an ophthalmologist who treats patients with this syndrome.
Case Report | | |
A 3-day-old Indian girl was referred to the oculoplasty clinic for ophthalmic evaluation. She was admitted in pediatric intensive care unit for right-sided multifocal clonic seizures and was well controlled with phenobarbital. The baby was born out of non-consanguineous marriage, by normal vaginal delivery at term, to a primigravida mother with an uneventful pregnancy.
General physical examination at birth showed: Length 48 cm (50 th centile), weight 2.5 kg (5 th centile), and head circumference 38 cm (97 th centile). Ophthalmic examination showed proptosis of the right eye, mechanical ptosis, upper eyelid atypical coloboma, ocular discharge, bulbar conjunctival hypertrophy, limbal dermoid of 4 × 3 mm extending from 1 to 5 O'clock, and corneal clouding [Figure 1] and [Figure 2]a. The left eye showed conjunctival congestion, corneal vascularization extending from 12 to 2 O'clock, and rest of the anterior segment was normal [Figure 2]b. Fundus examination of the right eye showed chorioretinal coloboma and optic disc coloboma. Fundus examination of the left eye was normal. Dermatological examination showed soft, nodular mass at right lateral canthus; measuring 7 × 7 mm, multiple patches of alopecia, 'nevus psiloliparus,' 'S'-shaped hypoplastic skin lesion extending from mid-forehead to root of the nose, multiple punched out lesions (focal skin aplastic lesions) on the occipital region of the scalp, and a lipoma in the fronto-temporal region [Figure 3], [Figure 4], [Figure 5]. The child had multifocal clonic seizures mainly confined to right side of body. Neurological examination displayed hypotonia. Conjunctival swab from the right eye grew Staphylococcus aureus that was sensitive to ciprofloxacin, tobramycin, and oxacillin. Topical tobramycin 0.3% solution, four times a day was prescribed resulting in resolution of ophthalmia neonatorum. Incisional biopsy was taken from hypertrophic bulbar conjunctiva of the right eye, which revealed features of lipodermoid. Ocular B-scan ultrasonography revealed normal-sized eyeballs with calcification of the right globe. Transfrontal neuro-ultrasound disclosed hydrocephalus and agenesis of corpus callosum [Figure 6]. CT scan of the brain and orbit revealed focal calcification of right globe, fatty infiltration in anterior orbit, intracerebral cyst measuring 14 × 7 cm compressing right ventricle, intracerebral calcification, and lipoma near right cerebello-pontine angle (0.6 × 0.5 cm) and in right cerebrum measuring 1.2 × 1.5 cm [Figure 7] and [Figure 8]. Electrocardiography, echocardiography, abdominal ultrasonography, magnetic resonance imaging of spine, and x-ray of the jaw were unremarkable. A chromosomal study (conventional G-banding) showed a normal karyotype (46, XX). The constellation of these clinical and imaging findings led to a definitive diagnosis of ECCL. | Figure 1: Mechanical ptosis and proptosis of the right eye, upper eyelid coloboma (black arrow), fullness in eyelids, conjunctival hypertrophy (white arrow), and conjunctival discharge

Discussion | | |
Haberland and Perou first described this syndrome in 1970 and coined the term 'Encephalocraniocutaneous lipomatosis'. [3] Subsequently, Fishman et al. in 1978 and Fishman in 1987 reported three additional cases of ECCL. Hence, it was also termed as Fishman syndrome. [4],[5] Approximately, 77 patients with the ECCL (PubMed search, accessed on 09-09-2013) have been reported in the literature. [1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13] No epidemiological data on incidence of the disorder is available. There is no clear gender, racial, or geographical predilection. [1],[2],[6]
The pathogenesis of the syndrome still remains unclear. There is no evidence as yet of genetic transmission or chromosomal abnormality. Somatic mosaicism is thought to be the underlying pathophysiology in ECCL. Dysgenesis of the cephalic neural crest and the anterior neural tube is one of the most widely accepted theory of pathogenesis of ECCL. [3]
Encephalocraniocutaneous lipomatosis has a very wide and variable spectrum of clinical manifestations. [1],[2] Phenotypic spectrum of ECCL is given in [Table 1]. Ophthalmia neonatorum in this case seemed to be a coincidental finding. | Table 1: Phenotypic spectrum of Encephalocraniocutaneous lipomatosis[1-13]

Sometimes, the diagnosis of the syndrome may be difficult due to absence of any pathognomonic morphological feature or specific molecular marker or laboratory test and its highly variable expressivity. [1],[2],[7] Although nevus psiloliparus is a very specific feature of ECCL, it has also been reported independently in non-syndromic patients. [1],[2],[8] The diagnosis of ECCL is mainly based on history, clinical examination, and imaging studies. Mac Laren et al. in 1995 and Hunter in 2006 have laid down diagnostic criteria. [2],[9] In 2009, Moog proposed revised diagnostic criteria for ECCL. [1] The Moog's revised criteria for diagnosis of ECCL is shown in [Table 2]. | Table 2: Moog's revised diagnostic criteria for encephalocraniocutaneous lipomatosis (ECCL)[6]

Differential diagnosis includes oculocerebrocutaneous syndrome (Delleman-Oorthuys syndrome), nevus sebaceous syndrome, proteus syndrome, Sturge- Weber syndrome More Details More Details, oculo-auriculo-vertebral syndrome (Goldenhar syndrome), neurofibromatosis type-1, focal dermal hypoplasia syndrome (Goltz syndrome or Gorlin-Goltz syndrome), epidermal nevus syndrome (Schimmelpenning syndrome), and oculoectodermal syndrome. [10] The minimal diagnostic criteria for Delleman-Oorthuys syndrome (oculocerebrocutaneous syndrome) includes a CNS cyst or hydrocephalus, microphthalmia with orbital cyst, and focal dermal hypoplasia or aplasia. [11] As microphthalmia with orbital cyst was missing from the present case, hence this did not appear to be a case of Delleman-Oorthuys syndrome. In the present case, the right eye has proptosis and mechanical ptosis. This seems to be from conjunctival hypertrophy and lipomatous infiltration of conjunctiva, eyelids, and anterior orbit. However, computed tomography scan did not reveal any space occupying lesion in the posterior orbit.
Many patients with ECCL lead normal lives. [1],[2] Complications related to CNS malformation may be a cause of increased morbidity and mortality in these patients. These patients are also at risk for developing certain neoplasms such as juvenile extranasopharyngeal angiofibroma of gingiva, papillary glioneuronal tumor, and low-grade glioma/astrocytoma. [1],[2],[6],[7],[10],[11],[12] Therefore, screening for these conditions is crucial during follow-up.
A definitive antenatal diagnosis is not possible because intracranial malformations observed on an antenatal sonogram are not specific for ECCL. [13] There are no effective treatment modalities for ECCL. Ophthalmic management of these cases is limited to excision of choristomas with or without lamellar keratoplasty, removal of cutaneous lesions for cosmetic improvement, and visual rehabilitation. The patient should be followed-up regularly for development of complications and appropriate management.
