Vismodegib for Preservation of Visual Function in Patients with Advanced Periocular Basal Cell Carcinoma: The VISORB Trial.

Oncologist 2021 May 14. Epub 2021 May 14.

Rogel Comprehensive Cancer Center, University of Michigan, Ann Arbor, MI.

Background: Basal cell carcinoma (BCC) is a common skin cancer often curable by excision; however, for patients with BCC around the eye, excision places visual organs and function at risk. Here we test the hypothesis that use of the hedgehog inhibitor vismodegib will improve vision-related outcomes in patients with orbital and extensive periocular BCC (opBCC).

Methods: In this open label, non-randomized phase 4 trial, we enrolled patients with globe- and lacrimal drainage system-threatening opBCC. Read More

Microdeletion of 9q22.3: A patient with minimal deletion size associated with a severe phenotype.

Am J Med Genet A 2021 May 7. Epub 2021 May 7.

Mater Research Institute-University of Queensland, Translational Research Institute, Woolloongabba, Queensland, Australia.

Basal cell nevus syndrome (also known as Gorlin Syndrome; MIM109400) is an autosomal dominant disorder characterized by recurrent pathological features such as basal cell carcinomas and odontogenic keratocysts as well as skeletal abnormalities. Most affected individuals have point mutations or small insertions or deletions within the PTCH1 gene on human chromosome 9, but there are some cases with more extensive deletion of the region, usually including the neighboring FANCC and/or ERCC6L2 genes. We report a 16-year-old patient with a deletion of approximately 400,000 bases which removes only PTCH1 and some non-coding RNA genes but leaves FANCC and ERCC6L2 intact. Read More

Differential Diagnosis and Management on Seborrheic Keratosis in Elderly Patients.

Clin Cosmet Investig Dermatol 2021 28;14:395-406. Epub 2021 Apr 28.

Dermatology Unit, University of Campania, Naples, Italy.

Seborrheic keratoses are exceedingly common in the elderly and usually are easy to diagnose and do not require treatment. However, given their great variety of clinical presentation, they may give rise to false-positive cases, meaning that they may at times mimic melanoma, squamous cell carcinoma and basal cell carcinoma. On the other hand, melanoma may mimic seborrheic keratosis, leading to incorrect patient management. Read More
