Vascular malformations enlarge overtime, particularly during adolescence when follicle-stimulating hormone (FSH) rises. Lesions contain the receptor for follicle-stimulating hormone. FSH also becomes elevated during menopause. We present a patient with a venous malformation of the lip that presented for the first time after she entered menopause which was temporally related to a significant increase in her serum FSH levels that were measured. This observation supports the hypothesis that FSH might influence the pathophysiology of vascular malformations.

Introduction: related disorders (PRD, OMIM: *171834) are genetic disorders resulting from pathogenic somatic mosaic variants in the gene, which encodes a protein crucial for regulating cell growth and division. PRD typically manifest during the post-zygotic phase, leading to a broad spectrum of overgrowth and vascular malformations affecting various body regions.
Methods: Conventional diagnostic methods struggle to detect and confirm pathogenic PIK3CA gene variants due to the mosaic nature of these disorders and the limited accessibility of affected tissues.

We present a pioneering case of a duplication of the common bile duct associated with agenesis of the dorsal pancreas in a 66-year-old man. After an episode of cholestatic jaundice, radiological investigations revealed complex vascular and biliary anomalies, redefining the therapeutic strategy. Instead of risky surgery, endoscopic biliopancreatic drainage resolved the symptoms.

Background: Blue rubber bleb nevus syndrome (BRBNS) is a rare venous malformation disorder. Currently, there is no standard therapy for this disease. However, lauromacrogol, a sclerosant extensively utilized in the management of vascular malformations, has been applied in the treatment of BRBNS.

Lymphatic malformation is a rare vascular anomaly caused by abnormal lymphatic system development during embryogenesis. Intra-abdominal lymphatic malformations are uncommon in children, and surgical excision is considered the gold standard for treatment. However, few reports of minimally invasive laparoscopic approaches have been documented.
