  • Title: Posterior scleral choristoma in the organoid nevus syndrome (linear nevus sebaceus of Jadassohn).
    Author: Traboulsi EI, Zin A, Massicotte SJ, Kosmorsky G, Kotagal P, Ellis FD.
    Journal: Ophthalmology; 1999 Nov; 106(11):2126-30. PubMed ID: 10571348.
    Abstract:
    PURPOSE: To highlight the association of posterior osseous and/or cartilaginous ocular choristomas with epibulbar choristomas and the nevus sebaceus of Jadassohn. DESIGN: Small case series. PARTICIPANTS: Four patients with the organoid nevus syndrome. METHODS: Clinical and histopathologic studies in four patients with epibulbar lesions and nevus sebaceus of Jadassohn. MAIN OUTCOME MEASURES: Ophthalmoscopic findings of peripapillary lesions. Computed tomographic and ultrasonographic characteristic of posterior scleral lesions. Ocular histopathologic findings in one globe from one of the study subjects. RESULTS: Three patients had the triad of posterior osseous/cartilaginous ocular choristomas, anterior epibulbar choristomas, and nevus sebaceus of Jadassohn and one patient had anterior epibulbar choristomas and posterior osseous/cartilaginous ocular choristomas. Ultrasonography and computed tomography were valuable in detecting scleral ossification or epibulbar cartilage or both. The ophthalmoscopic findings were similar to those of a choroidal osteoma. CONCLUSIONS: The presence of posterior osseous/cartilaginous ocular choristomas in a patient with epilepsy or epibulbar lesions or both suggests the diagnosis of nevus sebaceus of Jadassohn. Osseous/cartilaginous ocular choristomas should be suspected in patients with nevus sebaceus of Jadassohn and peripapillary hypopigmented fundus lesions.
