Epidermal nevus syndrome with maxillary involvement

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.

Inflammatory linear verrucous epidermal nevus and regional odontodysplasia: A rare sorority

Epidermal nevi are hamartomatous lesion and its association with other developmental defects particularly of the central nervous system, eye and skeletal system are well recognized. We report a rare case of inflammatory linear verrucous epidermal nevus syndrome along with regional odontodysplasia; and to the best of our knowledge this is the second case reported in the literature.

Oral linear epidermal nevus: a review of the literature and report of two new cases

Linear epidermal nevus (LEN) is a sporadic hamartomatous lesion of the skin due to the proliferation of clones of embryonic ectodermal cells, which are arranged according to a typical linear configuration known as Blaschko's lines. Oral involvement of LEN is very rare and few cases have been reported in the medical literature. We report two new cases of LEN with exclusive oral involvement, which presented with the typical unilateral or midline distribution. Oral LEN presents as an exophytic lesion with well defined borders and a verrucous or papillary surface which correspond, histologically, to epithelial papillomatosis with a moderate degree of hyperkeratosis and acanthosis. Oral LEN appears mainly at birth, grows slowly during childhood and stabilize by adolescence. Localized lesions do not show any recurrence after surgical removal but widespread lesions seem to have more risk of recurrence and are more difficult to manage. Functional problems and malignant transformation have not been reported.
