Gorlin syndrome (GS) is a rare hereditary multisystem disorder caused by mutations in , or . It is characterized by multiple anomalies and an increased risk of developing various tumors. Basal cell carcinoma is most common, and medulloblastoma (MB) is especially frequent in patients with mutations. MB treatment often includes radiation therapy in patients older than 3 years; however, such treatment is very toxic to patients with GS. Most reported cases of MB in patients with GS present after GS is diagnosed. We report a male toddler with multicentric posterior fossa tumor and calcifications along the falx cerebri, suggesting MB and GS. Pathology revealed nodular MB. His testing confirmed a germline mutation. His tumor resolved with three induction cycles of chemotherapy, but he died of respiratory failure due to infection at 20 months of age. Overlooking calcifications along the falx cerebri in children with MB can induce significant morbidity.

The association between genetic syndromes and odontogenic tumors encompasses several entities, reflecting the intricate interplay between genetic factors and the development of these lesions. The present study aimed to comprehensively investigate the associations between genetic syndromes and odontogenic tumors. We delineated the diverse spectrum of syndromic connections, including key syndromes such as Gardner syndrome, Gorlin syndrome, Schimmelpenning syndrome, and others.

Purpose: This study aimed to evaluate odontogenic keratocysts associated with basal cell nevus syndrome (BCNS) using computed tomography (CT) and magnetic resornance imaging (MRI) including diffusion-weighted imaging (DWI) and compare them with sporadic cases.
Materials And Methods: This study investigated 17 outpatients who underwent panoramic radiography, CT, and MRI between August 2012 and January 2021. Five of these patients had BCNS had 16 odontogenic keratocysts, for which the authors recorded detailed findings.

Article Synopsis
- - The study examines the rare skeletal anomaly known as bifid rib, which appears in less than 1.5% of the population and faces challenges in identification due to postmortem damage and similarity to other conditions.
- - It presents five cases of rib bifurcation from four individuals across different populations in the Kujawy region of Poland, analyzed through morphological and paleoradiological methods.
- - The research also critiques existing evidence linking bifurcated ribs to naevoid basal cell carcinoma syndrome and proposes a new way to classify this anomaly in osteological studies.
A new nonsense mutation of PTCH1 gene in mother and daughter with late-onset nevus basal cell carcinoma syndrome: Case report.

Department of Dermatology, The Affiliated Hospital of Inner Mongolia Medical University, Hohhot, China.
Article Synopsis
- - The study focuses on Nevoid basal cell carcinoma syndrome (NBCCS), a rare condition linked to high rates of basal cell carcinoma, potentially caused by mutations in the PTCH1 gene.
- - Researchers identified a new nonsense mutation in the PTCH1 gene in a mother and her daughter, both of whom also had ovarian mature teratomas.
- - Treatment outcomes showed persistent issues for both individuals, underscoring the complex effects of the mutation and related health challenges.
