[Infantile acropustolosis: unusual manifestation of scabies in the infant?].

Three pediatric cases of vesiculopustules persisting for several months or years after eradication of Sarcoptes scabiei are reported. This particular course of scabies in infants is underrecognized although probably common. Its clinical manifestations, natural history and histologic features are identical to those seen in infantile acropustulosis, a recently individualized syndrome whose pathogenesis is unelucidated. In the light of these cases and a review of the literature, the possible relationship between scabies and infantile acropustulosis is discussed.

[Acrokeratoelastoidosis].

We record a case of an 18 year old female patient with a history of asymptomatic, keratotic, waxy papules localized over the thenar and hypothenar eminence of palms and the internal aspect of the soles of feet. Histologically they were characterized by hyperkeratosis, acanthosis, elastorrexis and enlarged collagen fibers, typical of the picture known as Costa's acrokeratoelastoidosis. We establish a differential diagnosis with other clinically similar keratotic conditions.

[Bazex's para-neoplastic acrokeratosis. A clinical case with hyperpigmentation].

We studied a white skin type 3 male patient aged 68 years old with a paraneoplastic acrokeratosis of Bazex, suffering from an oesophagus neoplasm. Cutaneous manifestations preceded in months the cancer. Dermatosis affected fingers of hands and feet, soles, nose and helix. Black melanic hyperpigmentation was the first cutaneous sign and were followed by an hyperkeratosis, becoming the most clinical characteristic of the syndrome. The sequence of these signs induces us to suggest that hormonal factors elaborated by the tumoral cells are the ones responsible for the pigmentary changes since they appeared before the hyperkeratosis.

[Idiopathic neuroarthropathy in a woman (author's transl)].

The authors report a case of idiopathic and sporadic neuroarthropathy in a 53 year - old woman and point out the rarety of the disease in women unstead of familial Thevenard disease and diabetic neuroarthropathy.

[Skin changes in alimentary zinc deficiency caused by artificial infant food].

We report on 2 non-related newborn children who developed erythematosquamous skin eruptions on both their faces and the extensor sides of their fingers at the 4th and 10th week after birth, resp. Both children had been fed upon hypoallergenic formulas since birth. Serum investigations revealed decreased zinc levels: 0.4 and 0.17 mg/l, resp. (normal values: 0.59-0.96 mg/l). Following zinc substitution with zinc sulphate 10 mg daily for 3 days, the serum zinc levels of both children had increased to normal values and remained stationary during continued treatment with 3 mg zinc daily. The skin eruptions disappeared a few days after the start of treatment.

Acquired zinc deficiency in two breast-fed mature infants.

Zinc deficiency was diagnosed in a breast-fed mature infant and her sister. In both infants the characteristic dermatitis appeared on the face and buttocks around 10 weeks of age. It responded rapidly to zinc supplements. Their mother's serum zinc level was slightly low but her milk was found to be remarkably low in zinc. Oral zinc supplementation could correct only her serum zinc level but not her low breast milk zinc level. Therefore the mother's deficiency in the transfer process of zinc from serum to breast milk was suspected as a cause of the skin changes in her children. These cases indicate that even mature infants, who feed exclusively on mother's milk, run a risk to develop zinc deficiency, if the concentration of zinc in the breast milk is very low.

[Infantile acropustulosis].

Infantile acropustulosis starts in the first few months of life with the recurrent appearance of pruritic intraepidermal pustules containing neutrophils. Predilection sites are the hands and feet. Episodes of pustular eruptions lasting from 8 to 14 days are followed by longer intervals with no symptoms. However, some infants present with skin lesions more widely distributed over the body and with eosinophils as a major constituent of the pustules. In these cases differentiation from other eosinophilic pustular dermatoses of infancy, e.g., the pustular variant of toxic erythema, eosinophilic pustular folliculitis, and transient neonatal pustular melanosis, may become difficult. The etiology of infantile acropustulosis is unknown. The disease clears up spontaneously within the first few years of life. In some cases DADPS therapy has been of benefit.

The Klippel-Trenaunay syndrome with acro-angiodermatitis (pseudo-Kaposi's sarcoma).

A patient with the Klippel-Trenaunay syndrome and pseudo-Kaposi elements is reported. This combination of symptoms has only been published very occasionally. Selective quantitative measurements of the peripheral tissue blood flow revealed a significantly increased cutaneous blood flow in the hypertrophied leg. This finding supports the assumption that a high perfusion rate and a high oxygen saturation are involved in the etiopathogenesis of the pseudo-Kaposi elements.

[Association of idiopathic acropustuloses to HLA antigens and their relation to psoriasis].

Immunogenetical findings can contribute to the understanding of diseases of unknown etiology. It has, however, become difficult to define the borderlines between related diseases, since a vast amount of individual facts have been reported. For this reason, immunogenetical findings should only be seen as a part of general pathology. Our study, which makes use of HLA markers, is an attempt to provide a better definition of idiopathic acropustulosis, and to differentiate it more clearly from psoriasis.

[Gianotti-Crosti syndrome in an adult].

A 31 years old woman had an exanthematic eruption of small and acral distributed papules. At the same time she suffered a clinical and biological hepatitis B. This case is described attending to the clinic, histopathology and direct immunofluorescence. By the way the Gianotti-Crosti syndrome is reviewed.
