Gorlin syndrome is a rare autosomal dominant disease caused by mutations in the PTCH1, PTCH2, and SUFU genes. Each symptom of the disease has a different time point of onset, which makes early diagnosis based solely on symptoms challenging. In this study, a gene panel was developed to overcome the challenges in the diagnosis of Gorlin syndrome and allow diagnosis using a single test. Read More

Activating mutations in the Hh pathway underlies the development of sporadic and familial skin BCC. For these oncogenic proliferations displaying ligand-independent activation of the intracellular pathway, two molecules have been approved for therapeutic purposes: vismodegib and sonidegib. Improper Hh signalling occurs in many human tumours also via a paracrine mechanism (ligand-dependent) in which the secretion of Hh ligands by stromal cells support tumour growth. Read More

This case describes the occurrence of basal cell carcinoma (BCC) and sebaceoma within a nevus sebaceous (NV), which has not yet been previously reported. This is significant to dermatologists as it emphasizes the importance of close monitoring of benign sebaceous nevi in the event that malignant transformation occurs, although such occurrences are rare. Prompt consideration for prophylactic excision of NS is warranted prior to malignant transformation. Read More

Keratocysts, which are benign cystic lesions that usually arise in the jawbones, particularly the mandible, can rarely occur in the skin and soft tissues. Odontogenic keratocysts, which are keratocysts in the jaw, are considered hallmarks of nevoid basal cell carcinoma syndrome (NBCCS). In contrast, cutaneous keratocysts (CKCs), which can occur in association with NBCCS, are rare. Read More

Background: Basal cell carcinoma (BCC) is the most frequently diagnosed malignancy worldwide and an ever increasing annual incidence is observed. However, nationwide registries of BCCs are very rare, and often extrapolation of the data has been necessary to estimate the absolute number of diagnoses. As of September 2016, all histopathologically confirmed BCCs are registered in the Netherlands, due to developments in automatic notification and import in the Netherlands Cancer Registry. Read More
