Disseminated angiokeratomas can be seen in patients with an inherited deficiency of alpha-l-fucosidase as well as in patients with classic
Fabry's disease
. Patients with deficiency of this lysosomal enzyme, or
fucosidosis
, have spasticity, mental retardation, and retardation of growth in addition to angiokeratomas. We herein report three new cases of this rare syndrome.

An outline of the pathways of catabolism of four sphingolipids to ceramide, along with structural details of a few constituents, serves as a framework for better understanding of the sphingolipidoses. The four sphingolipids are sulfatide, sphingomyelin, globoside, and ganglioside GM1. Diseases which can be incorporated into the scheme include Niemann-Pick disease, Gaucher disease, metachromatic leukodystrophy, Krabbe disease, ceramide lactoside lipidosis, Tay-Sachs disease, generalized gangliosidosis,
Fabry disease
, and Sandhoff disease.
Fucosidosis
probably also belongs with this group. GM3 (hematoside) sphingolipodystrophy involves blocks in synthetic rather than catabolic pathways.

The oral lesions in two previously reported cases of
fucosidosis
are discussed. The patients have coarse facies, severe mental retardation, spondyloepiphyseal dysplasia, deficiency of a-L-fucosidase, and red punctate lesions of the skin and oral mucosa. Gingival biopsy specimens showed that these lesions were identical to the
angiokeratoma corporis diffusum
reported in
Fabry's disease
, but had different locations. Because of the slowly progressing psychomotor retardation and recurrent upper respiratory tract infections that the prognosis for patients with this disease is poor. Treatment appears to be aimed at early diagnosis through amniocentesis.

Fabry disease
involves the different eye structures with variable frequencies. Typical alterations are the vascular lesions of the conjunctiva, the whirl-like opacities of the cornea, the wedge-shaped anterior opacities and the branching spokes of the lens, as well as the vascular lesions of the retina. Histopathologic examination correlates well with the observed symptoms. Several drugs may induce whirl-like opacities. The importance of the slit-lamp examination in
Fabry disease
has been further stressed by the discovery of
angiokeratoma corporis diffusum
in
fucosidosis
.

This paper describes radiological characteristics of the skeleton in a patient suffering from type II
fucosidosis
. The early symptom of anterior beaking of the vertebral bodies, in combination with mental retardation and
angiokeratoma corporis diffusum
, can suggest the possibility of type II
fucosidosis
.

Fucosidosis
is a rare, autosomal recessive, lysosomal storage disorder caused by a severe deficiency of alpha-L-fucosidase in all tissues. We have conducted a review of
fucosidosis
, compiling data from published reports and an international questionnaire survey. Seventy-seven patients affected with
fucosidosis
of which 19 had not been reported before have been identified. A major aim of the present study was to define the natural history of
fucosidosis
. The clinical picture of
fucosidosis
consists of progressive mental (95%) and motor (87%) deterioration, coarse facies (79%), growth retardation (78%), recurrent infections (78%), dysostosis multiplex (58%),
angiokeratoma corporis diffusum
(52%), visceromegaly (44%), and seizures (38%). Whereas the original
fucosidosis
patients described by Durand et al. (J. Pediatr 75:665-674, 1969) were decerebrate and died before age 5 years, most
fucosidosis
patients have a slower course of degeneration. Mortality before age 5 years was observed in only 7 patients (9%), whereas 36 patients (64%) reached the second decade. We did not find evidence for the existence of clinical heterogeneity with a rapidly progressive type I and a slowly progressive type II
fucosidosis
as suggested in the literature. Instead, there seems to exist a wide continuous clinical spectrum. At the biochemical level no heterogeneity in residual fucosidase enzyme activity or cross-reacting immunoreactive fucosidase protein was observed. At the DNA level at least 4 different mutations must be responsible for
fucosidosis
. These genotypic differences however do not explain the observed phenotypic differences.

Saposins (A, B, C, and D) are small glycoproteins required for the hydrolysis of sphingolipids by specific lysosomal hydrolases. Concentrations of these saposins in brain, liver, and spleen from normal humans as well as patients with lysosomal storage disease were determined. A quantitative HPLC method was used for saposin A, C, and D and a stimulation assay was used for saposin B. In normal tissues, saposin D was the most abundant of the four saposins. Massive accumulations of saposins, especially saposin A (about 80-fold increase over normal), were found in brain of patients with Tay-Sachs disease or infantile Sandhoff disease. In spleen of adult patients with Gaucher disease, saposin A and D accumulations (60- and 17-fold, respectively, over normal) were higher than that of saposin C (about 16-fold over normal). Similar massive accumulations of saposins A and D were found in liver of patients with
fucosidosis
(about 70- and 20-fold, respectively, over normal). Saposin D was the primary saposin stored in the liver of a patient with Niemann-Pick disease (about 30-fold over normal). Moderate increases of saposins B and D were found in a patient with GM1 gangliosidosis. Normal or near normal levels of all saposins were found in patients with Krabbe disease, metachromatic leukodystrophy,
Fabry disease
, adrenoleukodystrophy, I-cell disease, mucopolysaccharidosis types 2 and 3B, or Jansky-Bielschowsky disease. The implications of the storage of saposins in these diseases are discussed.

A female case of
angiokeratoma corporis diffusum
without systemic involvement, with alpha-galactosidase A activity in the normal range, alpha-L-fucosidase in the lower levels of the normal range, and a few amount of urinary sialic acid is reported. Some problem about differential diagnosis with inherited disorders as
Fabry's disease
,
fucosidosis
, sialidosis is discussed. Although cases of
angiokeratoma corporis diffusum
without any underlying enzyme defect have been reported, we believe that
angiokeratoma corporis diffusum
is always related to known or unknown enzymatic defect, which activities could result in the normal range probably in relation to enzymatic polymorphism.

A new method is described for the detection of abnormal urinary oligosaccharide and glycopeptide excretion by thin layer chromatography and differential visualization of oligosaccharides and glycopeptides. This method permits rapid screening and identification of disorders characterized by oligosacchariduria and glycopeptiduria including alpha-N-acetylgalactosaminidase deficiency,
angiokeratoma corporis diffusum
with glycopeptiduria, aspartylglucosaminuria, galactosialidosis,
fucosidosis
, GM1 gangliosidosis and sialidoses 1 and 2. Of note, the characterization of the glycopeptide excretion profiles in patients with alpha-N-acetylgalactosaminidase deficiency and
angiokeratoma corporis diffusum
with glycopeptiduria revealed essentially identical patterns, indicating the metabolic relatedness of these two phenotypically distinct conditions. Use of this improved thin layer chromatographic method should enhance routine screening of patients for lysosomal storage diseases as well as permit the identification of new disorders resulting from defective oligosaccharide and/or glycoprotein metabolism.

A number of metabolic disorders are characterized by generalized angiokeratomas and neurologic dysfunction.
Fabry's disease
(
angiokeratoma corporis diffusum
universale) is an X-linked recessive disorder caused by a deficiency of alpha-galactosidase A.
Fucosidosis
is an autosomal recessive disorder caused by a lack of fucosidase. Sialidosis with deficiencies of neuraminidase and beta-galactosidase is the third important association.
