[Classification of vascular tumours and vascular malformations. Contribution of the ISSVA 2014/2018 classification].

The study of vascular anomalies, "angiomas", vascular tumours and vascular malformations is made difficult by the great variety and confusion of the names used in the literature for these diseases, some of which are rare. The great merit of the classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA), adopted in 2014 and modified in 2018, is to propose a unambiguous nomenclature and to try to group these lesions in a logical way, contrasting with the lists of the usual "classifications". This classification is based on the distinction between proliferative lesions (tumours and reactive lesions) and those which are due to a congenital anomaly of vascular morphogenesis (vascular malformations).

Surgical treatment of vulvar venous malformations without preoperative sclerotherapy: Outcomes of 18 patients.

Background: Our aim was to evaluate the benefit of surgical resection of the venous malformations (VMs) of the external female genitalia.

Methods: Over the period of 2009-2019, 18 consecutive females underwent surgical resection for vulvar VM. Evaluations included preoperative Doppler ultrasound, MRI, and pre-and postoperative photographic imaging.

Intramuscular venous malformations of the calf: Surgical treatment outcomes of 57 patients.

Objectives: To report the outcomes of surgical treatment of calf intramuscular venous malformations (IMVMs) on pain, functional limitation, and quality of life.

Methods: We retrospectively reviewed 57 consecutive patients who had surgery for IMVM of the posterior compartment of the leg between 2010 and 2015. Treatments were all done at a single institution.
