Complex limbal choristoma in nevus sebaceous syndrome

Ophthalmologic manifestations of organoid nevus syndrome: A series of 13 cases

Background

The organoid nevus syndrome is a rare neurocutaneous syndrome typified by cutaneous sebaceous nevus, seizures and epibulbar choristomas. The condition is associated with multiple ocular abnormalities. Herein, the authors aim to study and report the ophthalmic features of cases diagnosed with organoid nevus syndrome.

Methods

The authors retrospectively evaluated the records of patients with the organoid nevus syndrome who had presented to a tertiary care eye hospital in northern India. The ocular features were studied and entered in MS excel and the data were evaluated.

Results

Data of 13 patients with the organoid nevus syndrome were found. All 13 patients had cutaneous features in the form of Sebaceous nevus of Jadasson, 8 patients had alopecia of the scalp area, 2 had history seizures and 10 had arachnoid cysts on neuroimaging of the head. All 13 patients had a complex choristoma involving the ocular surface.

Conclusions

We conclude that the most common ophthalmologic features associated with organoid nevus are complex choristoma of the bulbar surface, scleral coat calcification and upper eyelid coloboma.

Multiple adenomatoid odontogenic tumors in a patient with Schimmelpenning syndrome

Schimmelpenning syndrome (SS) is a congenital neurocutaneous disorder characterized by the presence of linear nevus sebaceous, ophthalmic, neurologic, skeletal, urologic, and cardiovascular alterations. Oral manifestations related to SS mainly include dental defects, papillary lesions in the oral mucosa, giant cell lesions of the jaws, and odontogenic tumors. Here, we report the first case of multiple adenomatoid odontogenic tumor observed in a patient with SS.

Congenital complex corneal choristoma associated with unilateral bony calvarial defects, subcutaneous nodules, and alopecia

Complex corneal choristoma is a rare finding and its relationship with systemic disease is poorly understood. We present a 3-day-old boy with the constellation of left-sided congenital complex corneal choristoma, limbal dermoid, ipsilateral bony skull defects, and bilateral subcutaneous vascularized nodules with overlying alopecia and scalp nevi. To our knowledge this is the first case of complex choristoma involving the presence of associated bony calvarial defects. This presentation may contribute to a greater understanding of the systemic findings associated with the condition. Furthermore, it may shed light on the possible syndromic spectrum associated with complex choristoma and its underlying pathophysiology.
