Department of Pedodontics and Preventive Dentistry, D. Gorlin-Goltz syndrome, which is commonly known as Nevoid basal cell carcinoma syndrome NBCCS is a rare multisystemic disease that is inherited as an autosomal dominant trait.
Case Report A female patient 25 years old come to our department with chief complaint of swelling in bilateral cheeks. These swellings were present since birth.

Jaw cyst-basal nevus syndrome- Bifid Rib syndrome: Bifid, fused, or markedly splayed ribs. Offspring should be screened for BCC on a regular basis and should avoid excessive exposure to ultraviolet radiation. The syndrome is also known as multiple basal cell carcinoma syndrome NBCCShereditary cutaneomandibular polyonocosis, multiple nevoid basal cell epithelioma-jaw cysts, or bifid rib syndrome 2,4.
It is caused by mutations golin the patched tumor suppressor gene PTCHa human homologue of the Drosophila gene mapped to chromosome 9q Click here to View figure. CT scan of the brain showed lamellar calcification along the falx and tentorium Figure 5.

J Am Dent Assoc.
Check for errors and try again. From Wikipedia, the free encyclopedia. The fact that its transmission is autosomal dominant with good penetrance implies the need of genetic counseling. Health care resources for this disease Expert centres Diagnostic tests 64 Patient organisations 28 Orphan drug s 4. Lateral photograph shows the increased occipitofrontal circumference.
PTCH 1 mutations have been identified in 13 patients: The diagnostic criteria for nevoid BCC were established by Evans et al. Nevoid basal cell carcinoma syndrome. Pathogenesis of the syndrome is attributed to abnormalities in the long arm of chromosome 9 q The PTCH gene product is part of a receptor for the protein called Sonic Hedgehog, which is involved in embryonic development. Diagnosis, Gorlin-Goltz syndrome, odontogenic keratocyst.
The odontogenic keratocyst is frequently the presenting manifestation of this syndrome. Fig 5 These findings confirmed those jaw cysts were odontogenic keratocysts.
The histopathological examination of the enucleated tissue showed an odontogenic keratocyst on the right side gorlni Figure 6 ] and an odontogenic keratocyst with secondary infection on the left side. II Minor Criteria i Macrocephaly determined after adjustment with height.
Gorlin-Goltz syndrome | Radiology Reference Article |
Gorlin-Goltz syndrome is an inherited autosomal dominant disorder with complete penetrance and extreme variable expressivity. Histologically proven odontogenic keratocysts of the jaw. Mutations in PTCH1 also account for the majority of features in monosomy 9q They divided the diagnostic criteria as major criteria and minor criteria.
Antenatal diagnosis is possible with ultrasound scans and DNA analysis extracted from fetal cells after amniocentesis or chronic villus sampling. This gene is significant for embryonic structuring and cellular cycle, thus its mutation leads to the development of the disease including neoplasms.
Gprlin Center for Biotechnology InformationU. Underlying connective tissue capsule was loose fibrocellular, with supporting vasculature, extravasated blood elements, strands, and nests of odontogenic epithelium [Figures 7 a — c ]. golgz

The Orthopantomogram OPG of the patient revealed bilateral radiolucent lesions associated with an unerupted third molar tooth in the ramus of the mandible [ Figure 4 ].
The Gorlin-Goltz syndrome is an autosomal dominant inherited syndrome manifested by multiple defects involving the skin, nervous system, eyes, endocrine system, and bones.
Part 3 Immunocytochemistry of cytokeratin and other epithelial marker. The patient also gave a history of multiple jaw surgeries for cyst enucleation in the past.
All the cystic lesions of the jaw were enucleated surgically. Thorough extraoral and intraoral examinations along with OPG, skull and chest radiographs help in proper diagnosis of the condition.
Proper evaluation and characterization of clinical features are essential for the correct diagnosis and management.
