Heterozygous
Fabry's disease
has an inconstant expression and very few complications. The theory of X-chromosome inactivation which, according to Lyon, occurs hazardly, is illustrated by the fact that the disease is expressed even in hemizygous women. Ophthalmic manifestations, as detected by the slit lamp method, are almost constant, 80 p. 100 of women with the disease having a verticillate cornea. Angiokeratoma is present in 20 p. 100 of the cases. Episodes of paraesthesia of the hands and feet are less common; in most cases they are attributed to the disease retrospectively, during family investigations. In two girls aged 10 and 11 years respectively and without history of
Fabry's disease
the only symptom suggestive of the diagnosis was paroxysmal acroparaesthesia. In one of the girls acroparaesthesia was associated with acrocyanosis,
livedo
and acro-osteolysis, but concordance was the only argument in favour of a link with
Fabry's disease
. Alterations of the extremities have been reported in this disease, including palmar erythema and a bluish discoloration of the palms due to dilatation of the superficial veins. Only two cases of
livedo
have been published. Acrosteolysis has never been documented in
Fabry's disease
, and its presence must be confirmed in further cases. The diagnosis of heterozygous
Fabry's disease
in these 2 girls was confirmed by the finding of ceramide trihexoside in urine and by leucocyte alpha-galactosidase levels that were 25 to 30 p. 100 of values obtained in controls. A study of the family of one of the girls showed that the father was involved; this hemizygous type of the disease with a 10 p. 100 alphagalactosidase level was totally asymptomatic.(ABSTRACT TRUNCATED AT 250 WORDS)

There are several syndromes in which neurological and cutaneous alterations of vascular origin, among other symptoms, occur. The key point of this fact is that these cutaneous signs permit early diagnosis, thus helping in further recognition of more complex syndromes and preventing unnecessary, harmful and costly diagnostic procedures or having to wait until the appearance of neurological signs. Therefore, these diseases should be classified attending to the most notorious vascular lesions they show, though they may show other less frequent cutaneous vascular lesions. In this way, these syndromes can be classified as associated with nevus flammeus (Sturge-Weber, Shapiro-Shulman, Bonnet-Dechaume-Blanc, Cobb, Klippel-Trenaunay, Fegeler, Robert), cavernous hemangiomas (Maffucci, blue-rubber-bleb-nevus, Proteus, Bannayan-Zonana, Riley-Smith, familial cavernous angiomatosis, POEMS syndrome), capillary hemangiomas (Rubinstein-Tayabi, Coffin-Siris, PHACE syndrome), telangiectasia (congenital telangiectatic cutis marmorata, Rendu-Osler-Weber, ataxia telangiectasia, Cockayne, De Sanctis-Cacchione),
livedo
reticularis (Sneddon, Divry-van-Bogaert), angioqueratoma (
Fabry disease
, Fucosidosis) and hemangioblastoma (Von Hippel-Lindau). Though we have tried that these vascular lesions should be named as angiomas if they are malformations and hemangiomas if they are benign neoplasias, they are called following morphological aspects rather than other criteria, due to their unknown origin.

The name capillary malformation has caused much confusion because it is presently used to designate numerous quite different disorders such as naevus flammeus, the salmon patch, the vascular naevus of the hereditary 'megalencephaly-capillary malformation syndrome' and the skin lesions of non-hereditary traits such as 'capillary malformation-arteriovenous malformation' and 'microcephaly-capillary malformation'. To avoid such bewilderment, the present review describes the distinguishing clinical and genetic criteria of 20 different capillary malformations, and a specific name is given to all of them. The group of capillary naevi includes naevus flammeus, port-wine naevus of the Proteus type, port-wine naevus of the CLOVES type, naevus roseus, rhodoid naevus, cutis marmorata telangiectatica congenita, congenital
livedo
reticularis, segmental angioma serpiginosum, naevus anaemicus, naevus vascularis mixtus and angiokeratoma circumscriptum. Capillary lesions that perhaps represent naevi are the mesotropic port-wine patch, Carter-Mirzaa macules, unilateral punctate telangiectasia and unilateral naevoid telangiectasia of the patchy type. Capillary malformations that do not represent naevi include X-linked
angiokeratoma corporis diffusum
(
Fabry disease
), autosomal dominant
angiokeratoma corporis diffusum
, hereditary haemorrhagic telangiectasia, hereditary angioma serpiginosusm and the salmon patch. In this way, we are able to discriminate between various non-hereditary capillary naevi such as naevus roseus and the hereditary rhodoid naevus and several hereditary traits that do not represent naevi such as
angiokeratoma corporis diffusum
and hereditary haemorrhagic telangiectasia; between four different types of port-wine stains, three of them being lateralized and one being mesotropic; between cutis marmorata telangiectatica congenita and congenital
livedo
reticularis; between telangiectatic naevi and the vasoconstrictive naevus anaemicus; and between two different types of
angiokeratoma corporis diffusum
. Finally, arguments are presented why the salmon patch ('stork bite', 'naevus simplex') cannot be categorized as a naevus.
