Drug holiday approach for Vismodegib treatment in patients with nevoid basal cell carcinoma syndrome: Three cases from real clinical practice.

Sonic hedgehog pathway inhibitor Vismodegib is the first systemic treatment to be approved for metastatic or locally advanced basal cell carcinoma non-subsidiary of surgical treatment, and appears to be a promising treatment option for patients with nevoid basal cell carcinoma syndrome. In these patients, where repeated or prolonged treatment may be necessary, the psychological exhaustion caused by the chronicity of less severe adverse effects appears as the main limiting factor in the persistence of the drug in the long term and in the willingness of patients to take the drug again after its suspension. We report our experience with three cases where a drug holiday approach was effective in decreasing the intensity of adverse effects or improving the patient's subjective tolerance to the drug while maintaining clinical response.

Ectopic intestinal mucosa implanted on the perianal skin of a patient with Crohn disease.

Intestinal mucosa implanted in skin is an exceedingly rare occurrence. Implantations are thought to occur during the creation of ostomy sites or other surgical procedures in which suture goes through bowel mucosa and then skin. Current ostomy literature reports this as a very uncommon complication.
