[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).

[Nevoid acanthosis nigricans or RAVEN (rounded and velvety epidermal nevus): three cases].

Background: We report three cases of a peculiar rash with mixed clinical features of both epidermal nevus and acanthosis nigricans. Their characteristics have been compared to those of very rare but similar cases found in the medical literature.

Patients And Methods: Two young adults (one male, one female) and a 7-year-old boy consulted for hyperchromic asymptomatic plaques located respectively on the right scapula, the left upper arm and the right frontotemporal area of the face.

[PELVIS/SACRAL syndrome with livedoid haemangioma and amniotic band].

Background: PELVIS or SACRAL syndrome denotes the association of local haemangioma and malformation in the pelvic region. In this paper, we report a case noteworthy on account of the initially livedoid appearance of the haemangioma as well as associated amniotic banding of an upper limb.

Patients And Methods: A newborn male infant underwent left colostomy on the day of birth due to anal imperforation and anomalies of the external genital organs with sexual ambiguity.

[Arteriovenous malformations: a study of 200 cases].

Objective: The aim of this study was to analyze the natural history of arteriovenous malformations by reviewing 200 consecutive cases observed in all localizations between 1992 and 1996 in a multidisciplinary angioma clinic.

Patients And Methods: Files concerning 200 arteriovenous malformations were reviewed with a standardized observation sheet applying the severity criteria defined by the International Society for the Study of Vascular Anomalies. We used the Schobinger staging system which includes 4 grades of severity: grade I=dormancy, grade II=expansion, grade III=destruction, grade IV=cardiac decompensation.

IgA-epidermolysis bullosa acquisita in a child resulting in blindness.

Epidermolysis bullosa acquisita (EBA) is an acquired subepidermal bullous disease characterized by IgG autoantibodies directed against type VII collagen, the major component of anchoring fibrils. The classical phenotype of EBA is a non-inflammatory, mechanobullous disease resembling the dystrophic forms of inherited epidermolysis bullosa. Mucous membrane involvement is frequent but usually mild.

The current management of cervico-cephalic venous malformations.

Venous malformations are often detected at birth and progressively increase in size if not treated. They can have severe aesthetic and functional consequences. Our purpose is to evaluate therapeutic results with Ethibloc.

[Surgical treatment of superficial vascular malformations. Indications for tissue expansion].

The aim of this work was to demonstrate the feasibility of surgical exeresis of superficial vascular malformations using tissue expansion. A retrospective analysis of data from 15 patients who underwent surgery over a 9 year period for arteriovenous (n = 6) and venous malformations of the trunk and limbs was made. Indications for treatment were pain in six patients or complications of an arteriovenous malformation.

[Cutaneous cicatrizing agents].

Cutaneous healing is an important field of dermatology for it concerns superficial wound, as well as little surgery action, leg ulcer, eschar or burn. In spite of the claiming of their healing properties and their profusion, only a few have been tested and have proved their efficiency. Use precautions must be complied with paying the highest attention among others to the condition of the wound before product applying, the sensitization risk and the systemic risk particularly for young child.

Percutaneous embolization with Ethibloc of lymphatic cystic malformations with a review of the experience in 70 patients.

Cystic lymphatic malformations (CLM) are superficial vascular hemodynamically inactive malformations of the lymphatic compartment. We propose a new approach which uses a sclerosing agent as an alternative to surgical resection. In the past nine years we treated 70 patients with CLM.

[Temporo-masseter vascular malformations].

Temporo-masseterine vascular malformations are mature capillarovenous malformations. Being congenital lesions, they are present at birth and progress throughout life, particularly before adolescence. The clinical diagnosis rests on the finding that the malformation swells when the patient is in supine position.

[Port wine hemangioma].

Port wine stains are mainly due to an increase in the number or size of dermal capillary vessels. They are a natural disgrace which, in their most common form (i.e.

[Immature hemangiomas in children].

Immature haemangiomas affect only infants and children and follow a peculiar course: first an expansion phase, then an involution phase which ends in complete cure in the majority of cases. Because of this favorable outcome, all inopportune treatments must be avoided, and abstention is the best attitude. However, early corticosteroid therapy must be prescribed when the lesion is located in a dangerous area, such as the eyelids or the lips.

[Indications for laser in the treatment of capillary hemangioma].

Port-wine stains (PWS) are the only angiomas concerned with laser treatment. Before availability of tunable dye laser, Argon laser has to be consider as more efficient and safer than CO2 or yag lasers in that indication. As it is painful and not devoid of scarring effect in children it must be used after puberty.

[Management of hemangioma in the infant].

Foster child hemangioma management depends on its usual spontaneously regressive evolution as it is a transient and benign vascular tumor like lesion. Most of the time clinical follow up is the only management. Investigations are indicated if treatment is needed (for decision and follow up) concerning only hemangiomas with a bad functional or esthetic prognosis (peri-orificial lesions and large locations of the face) or complicated hemangiomas with life-risk as sub glottic hemangioma, Kasabach and Merritt Syndrome, diffuse and liver hemangiomatosis possibly associated to cardiac failure.

MR imaging of breast hemangioma in female infants.

Breast hemangioma in female infants is a rare benign lesion, prone to spontaneous regression. But when the lesion regresses there is a risk of breast atrophy if the breast bud is included in or very close to the hemangioma. A trial of corticosteroid therapy could be proposed to prevent this risk, but one must be sure that the breast bud is included in or very close to the hemangioma before treatment.

[Pseudo-Kaposi syndromes of vascular origin].

Pseudo-Kaposi's Sarcoma with vascular disease concern mainly acroangiodermatitis described by Mali--(with chronic venous insufficiency)--, arteriovenous malformations with angiodermatitis described by Stewart and Bluefarb, and pseudo-Kaposi's Sarcoma occurring after placement of arteriovenous shunt for hemodialysis. Search for relation ships between classical Kaposi's Sarcoma and new AIDS Kaposi's Sarcoma explains new interest devoted to Pseudo-Kaposi's Sarcoma.

Long-term effects in skin and thyroid after radiotherapy for skin angiomas: a French retrospective cohort study.

To evaluate the long-term effects of skin angioma irradiation, a recall programme was established which included the systematic recalculation of the radiation dose to the skin and the thyroid. 22% of the 6229 patients contacted had a dermatological examination which revealed cutaneous dystrophy in 81% of the 1137 exposed angiomas and in 39% of the 208 unexposed angiomas. The risk of dystrophy (telangiectasia, hypopigmentation, superficial and subcutaneous atrophy) was 12.

Atypical neutrophilic dermatosis with subcorneal IgA deposits.

A 26-year-old woman had a chronic vesiculopustular and ulcerating skin disease associated with fever and arthritis. Cutaneous biopsy specimens showed an extensive infiltration of the dermis and epidermis by neutrophils. Direct immunofluorescence (IF) revealed linear subcorneal IgA deposits.
