Nevoid Basal Cell Carcinoma Syndrome: Mutation Profile and Expression of Genes Involved in the Hedgehog Pathway in Argentinian Patients.

Cells 2019 Feb 11;8(2). Epub 2019 Feb 11.

Laboratorio de Nefrología Experimental y Bioquímica Molecular, Instituto de Investigaciones Médicas "Alfredo Lanari", Facultad de Medicina, Universidad de Buenos Aires, 1427 Buenos Aires, Argentina.

Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder characterized by multiple basal cell carcinomas (BCC), mainly caused by gene mutations. Our current study aimed to establish (1) germinal and somatic mutational status, (2) component and Hedgehog (HH) pathway targets gene expression patterns, and (3) profile variations according to the genetic background in BCC and normal surrounding skin (NSS). We collected 23 blood and 20 BCC patient samples and analyzed the gene using bidirectional sequencing and multiplex ligation-dependent probe amplification. Read More

Tetrad presentation of non-syndromic odontogenic keratocyst: An uphill diagnostic and therapeutic challenge.

Dent Med Probl 2018 Oct-Dec;55(4):447-451

Department of Oral Pathology and Microbiology, the A.B. Shetty Memorial Institute of Dental Sciences, NITTE (Deemed to be University), Deralakatte, India.

Odontogenic keratocyst (OKC), in the last decade sceptically referred to as keratocystic odontogenic tumor (KCOT), is known for its subclinical extensive growth potential and significant rate of recurrences. Odontogenic keratocyst, being the third most common cystic lesion (10-20%) of the maxillofacial region, is often recognized as a sporadic lesion and is well-documented in the literature. Multiple presentation of these cysts over a lifetime is relatively uncommon and is usually seen in conjunction with nevoid basal cell carcinoma syndrome (NBCC), orofacial digital syndrome, Noonan syndrome, Ehlers-Danlos syndrome, Simpson-Golabi-Behmel syndrome, or other syndromes.

Effect of the sonic hedgehog inhibitor GDC-0449 on an in vitro isogenic cellular model simulating odontogenic keratocysts.

Int J Oral Sci 2019 Jan 5;11(1). Epub 2019 Jan 5.

Department of Oral Pathology, Peking University School and Hospital of Stomatology, 22 South Zhongguancun Avenue, Haidian District, Beijing, China.

Odontogenic keratocysts (OKCs) are common cystic lesions of odontogenic epithelial origin that can occur sporadically or in association with naevoid basal cell carcinoma syndrome (NBCCS). OKCs are locally aggressive, cause marked destruction of the jaw bones and have a propensity to recur. PTCH1 mutations (at ∼80%) are frequently detected in the epithelia of both NBCCS-related and sporadic OKCs, suggesting that PTCH1 inactivation might constitutively activate sonic hedgehog (SHH) signalling and play a major role in disease pathogenesis.

Co-Inheritance of Autosomal Dominant Polycystic Kidney Disease and Naevoid Basal Cell Carcinoma Syndrome: Effects on Renal Progression.

Nephron 2018 26;140(4):282-288. Epub 2018 Oct 26.

Laboratorio de Nefrología Experimental y Bioquímica Molecular, Instituto de Investigaciones Médicas Alfredo Lanari, Universidad de Buenos Aires, Buenos Aires,

The calcium signalling and hedgehog (HH) signalling pathways operate in the primary cilium. Abnormalities in these pathways cause autosomal dominant polycystic kidney disease (ADPKD) and naevoid basal cell carcinoma syndrome (NBCCS) respectively. Several reports have proposed that hyperactivation of the HH pathway in animal models of polycystic kidney disease affects normal renal development and renal cyst phenotype. Read More

Non syndromic synchronous multiple odontogenic keratocysts in a western Indian population: A series of four cases.

J Clin Exp Dent 2018 Aug 1;10(8):e831-e836. Epub 2018 Aug 1.

MDS, Assistant Professor, Department of Oral Pathology, RUHS College of Dental Sciences, Jaipur, Rajasthan, India.

Odontogenic keratocysts (OKCs) are developmental odontogenic cysts affecting the maxillofacial region and their association with a syndrome especially Naevoid basal cell carcinoma syndrome (NBCCS) is a common occurrence in comparison to non syndromic multiple OKCs. In a first, we present a series of four non syndromic cases with multiple OKCs in western Indian population. The presence of multiple OKC in our present case series may be because of the multifocal nature of the lesion rather than its association with any syndrome. Read More

Severe PATCHED1 Deficiency in Cancer-Prone Gorlin Patient Cells Results in Intrinsic Radiosensitivity.

Int J Radiat Oncol Biol Phys 2018 10 2;102(2):417-425. Epub 2018 Jun 2.

Laboratory of Genomics and Radiobiology of Keratinopoiesis, CEA, DRF/IFJ/iRCM, INSERM/UMR967, Université Paris-Diderot, Université Paris-Saclay, Evry, France. Electronic address:

Purpose: Gorlin syndrome (or basal-cell nevus syndrome) is a cancer-prone genetic disease in which hypersusceptibility to secondary cancer and tissue reaction after radiation therapy is debated, as is increased radiosensitivity at cellular level. Gorlin syndrome results from heterozygous mutations in the PTCH1 gene for 60% of patients, and we therefore aimed to highlight correlations between intrinsic radiosensitivity and PTCH1 gene expression in fibroblasts from adult patients with Gorlin syndrome.

Methods And Materials: The radiosensitivity of fibroblasts from 6 patients with Gorlin syndrome was determined by cell-survival assay after high (0. Read More

Generalized basaloid follicular hamartoma syndrome versus Gorlin syndrome: A diagnostic challenge.

Pediatr Dermatol 2018 Nov 28;35(6):e396-e397. Epub 2018 Aug 28.

Department of Dermatology, College of Medicine, Drexel University, Philadelphia, Pennsylvania.

Basaloid follicular hamartoma is a relatively rare benign neoplasm of follicular origin that can be mistaken histologically for basal cell carcinoma, but hereditary forms of basaloid follicular hamartoma are associated with nevoid basal cell carcinoma syndrome, or Gorlin syndrome. The pathophysiology of basaloid follicular hamartoma development involves mutations in the patched gene, which is also causative in nevoid basal cell carcinoma syndrome. We present a mother and daughter with basaloid follicular hamartomas, with genetic testing confirming patched gene mutation in the daughter. Read More

Odontogenic keratocyst: imaging features of a benign lesion with an aggressive behaviour.

Insights Imaging 2018 Oct 31;9(5):883-897. Epub 2018 Jul 31.

Department of Clinical-Surgical, Diagnostic and Pediatric Sciences, University of Pavia, Pavia, Italy.

The latest (4th) edition of the World Health Organization (WHO) Classification of Head and Neck Tumours, published in January 2017, has reclassified keratocystic odontogenic tumour as odontogenic keratocyst. Therefore, odontogenic keratocysts (OKCs) are now considered benign cysts of odontogenic origin that account for about 10% of all odontogenic cysts. OKCs arise from the dental lamina and are characterised by a cystic space containing desquamated keratin with a uniform lining of parakeratinised squamous epithelium. Read More

Department of Stomatology, School of Dentistry, University of Sao Paulo, Av. Prof. Lineu Prestes 2227 (Butantã), São Paulo, 03178-200, Brazil.

Aims: The aim of this study was to compare the clinical and demographic features of 62 patients presenting sporadic odontogenic keratocysts (OKCs) or OKCs associated with nevoid basal cell carcinoma syndrome (NBCCS). In conjunction with this, we also evaluated the immunohistochemical expression of Shh, Ptch1, Ptch2, Smo, Gli1, Gli2 and Gli3 proteins in 86 OKCs. By doing this, we add to the understanding of the biology of this type of lesion, providing tools that will help facilitate the early diagnosis of NBCCS in those patients where the first manifestation is that of OKCs.

SOX9 Transcriptionally Regulates mTOR-Induced Proliferation of Basal Cell Carcinomas.

J Invest Dermatol 2018 Aug 14;138(8):1716-1725. Epub 2018 Mar 14.

Department of Dermatology, Columbia University Medical Center, New York, New York, USA.

Currently available smoothened targeted therapies in patients with basal cell nevus syndrome are associated with substantial tumor recurrence and clinical resistance. Strategies bypassing smoothened and/or identifying additional downstream components of the Hedgehog pathway could provide novel antitumor targets with a better therapeutic index. Sry-related high mobility group box 9 (SOX9) is a Hedgehog/glioma-associated oncogene homolog-regulated transcription factor known to be overexpressed in basal cell carcinomas (BCCs). Read More

Delayed Diagnosis of Gorlin-Goltz Syndrome: The Importance of the Multidisciplinary Approach.

J Craniofac Surg 2018 Sep;29(6):e530-e531

State University of Maringá, Maringá, Brazil.

Gorlin-Goltz syndrome (GGS), also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder with high penetrance and variable expressivity. The classic triad originally described by Gorlin and Goltz in 1960 is composed of multiple nevoid basal cell carcinomas (NBCCs), odontogenic keratocysts (OKCs) in the jaws and bifid ribs. in 1977, this triad was modified by Rayner et al, and to GGS diagnosis, the OKCs had to appear in combination with calcification of the cerebellar falx or palmar and plantar pits.

Orthokeratinized odontogenic cyst with calcification: A rare case report of a distinct entity.

J Oral Maxillofac Pathol 2018 Jan;22(Suppl 1):S20-S23

Department of Oral and Maxillofacial Surgery, Bharati Vidyapeeth (Deemed to be University) Dental College and Hospital, Sangli, Maharashtra, India.

Orthokeratinized odontogenic cyst (OOC) is a relatively rare odontogenic cyst, distinct from odontogenic keratocyst (OKC). In the 4 edition of WHO Classification of Head and Neck Tumors (2017), OOC has been included as a separate entity in the category of developmental odontogenic cysts. It presents as a unilocular radiolucent lesion in the posterior mandible and is frequently related to impacted teeth, thus mimicking dentigerous cyst. Read More
