Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is a hereditary condition transmitted as an autosmal dominant trait, due to a mutation in the tumor suppressor gene PTCH mapped to chromosome 9q 22.3-q31. It is a rare syndrome characterized by a series of developmental abnormalities and predisposition to various cancers. The Gorlin syndrome - Glotz combines several general clinical manifestations including many basal cell carcinomas and nevi, palmar-plantar hyperkeratosis, skeletal abnormalities, intracranial ectopic calcifications, facial dysmorphism with macrocephaly. The dentist have an important role in the diagnosis of this syndrome through maxillofacial signs specific to its expression including: keratocysts odontogenic, inclusions and dental ectopias that can be inaugural.

Gorlin-Goltz syndrome, also known as basal cell nevus syndrome, is an uncommon autosomal dominant hereditary disorder; which is characterized by numerous basal cell carcinomas, maxillary keratocysts and bones malformations. It results from a mutation of the PATCHED gene. The estimate incidence for a general population is 1/50000 to 1/150000. We present a 30 year-old woman, with no similar familial case, who had a repeatedly dental abscesses since the age of 15 years, she consulted for papulonodular lesions that have appeared at the age of eighty. Those lesions were localized on the face and the trunk, reminiscent of basal cell carcinomas. The clinical examination found papulonodular lesions, a mandibular fistula, broadened nasal root, palmer pits and a swelling at the right big toe. The dermoscopic examination of the papulonodular lesions showed a kind of trunk tree arborisation. The biopsy excision of the swelling at the right toe and papulonodulor lesions, revealed respectively an epidermoid cyst and basal cell carcinomas. Radiographic examination showed a calcified falx cerebri calcification, bifid ribs, synostosis, wedged, scoliosis and agenesis of the left kidney. Our patient was treated by a surgical excision of skin lesion with a setting flat of a mandibular fistula. Also a photoprotection was recommended and a regular monitoring of the skin lesions. The Evolution was marked by the emergence of new basal cell carcinomas treated by photodynamic therapy.

The authors present one patient with multiple oral cysts. The family history and the histological diagnostic showing multiple keratocysts, we suspect one form of Gorlin-Goltz syndrome. [ABSTRACT FROM AUTHOR]
