Basal cell nevus syndrome with unusual associated findings: A case report with 17 years of follow-up

Abstract

Background: Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin-Goltz syndrome (GGS), is an inherit-ed autosomal dominant disorder caused by mutations in the patched (PTCH) tumor-suppressor gene, which has high penetrance and variable phenotypic expressivity. In 1960, Gorlin and Goltz defined the condition by 3 main characteristics: multiple basal cell carcinomas, odontogenic keratocyst (OKC), and skeletal anomalies. Nowadays, many neurologic, ophthalmic, endocrine, and genital manifestations are known to be associated with this syndrome. Considering the complexity of the clinical manifestations, a multidisciplinary approach is necessary for the diagnosis and follow-up of patients with NBCCS. Case Report: We report the case of a 27-year-old woman who presented with multiple maxillary and mandibular OKCs, as well as mandibular dentigerous cysts, all detected by X-ray. The medical records of the patient reported other findings such as falx cerebri calcification, osteolysis in femoral bones, and focal bone alteration suggestive of simple bone cysts. Based on the presented manifestations, it was concluded that the patient had characteristics of NBCCS. A multidisciplinary approach was necessary, and odontological intervention was used in man-aging treatment of the jaw cysts. Conclusions: In view of this combination of findings, it is of primary importance for dental surgeons and physicians to be able to recognize the signs and symptoms of NBCCS in order to achieve an early diagnosis and avoid the progression of oral cysts, the metastasis of skin lesions, and progression of other less frequent manifestations.
