[Psoriasis in childhood].

Psoriasis is a common chronic disease in childhood of yet unclear etiology. Thirty per cent of psoriatic patients experience onset of their disease before 15 years of age. Psoriasis is exceptionally congenital but may present in infancy as a napkin dermatitis. There are specific pediatric clinical forms, but at the beginning the eruption is usually discrete, and the diagnosis can be difficult. Pustular, erythrodermic and arthropathic forms are rare. Treatment must weigh the advantages and disadvantages of the possible therapies and be kept to the minimum compatible with asymptomatic control.

[Granuloma annulare in the child].

Granuloma annulare is a benign, common, inflammatory skin lesion of unknown etiology that is seen in both adults and children. The typical lesions are single or multiple small cutaneous papules with an annular distribution. The histology is consistent with an area of fibrinoid degeneration of collagen, surrounded by palisading histiocytes and inflammatory cells. There are four clinically distinct subtypes: localized, generalized, subcutaneous and perforating. Usually a spontaneous resolution is expected. Many medical treatments have been proposed but without evidence of efficacy. The association with insulin dependent diabetes is still being discussed.

[Congenital pigmented nevus: prognosis and therapeutic possibilities].

Congenital pigmented nevi are found in approximately 1% of newborn infants. Two main factors determine their management: 1) the risk of malignancy (melanoma); 2) the aesthetic consequences, these factors being themselves dependent upon the size and the localization of the nevi. Thus, if the systematic resection of small nevi is not required, early treatment of giant nevi which carry a high risk of malignancy before the age of ten years, is highly recommended. Main methods of treatment are surgical resection (with the help of skin grafts, or cutaneous expansion or mobilization, in giant nevi), dermabrasion and curettage.

[Exanthematic pustulosis of pregnancy: favorable evolution using calcium and vitamin D2].

A 26-year-old pregnant woman was hospitalized in an emergency setting for a skin eruption. She had developed pustules distributed on round patch-like areas of rash localized at the umbilicus and the larger skin folds. She was given calcitriol and calcium with good results. Systemic steroids are usually given for exanthematic pustulosis of pregnancy but with variable efficacy. Few cases of successful treatment with calcium and vitamin D have been reported. We suggest this alternative treatment could be useful in other cases.

[Lichenoid eruptions in the child].

Lichenoid eruptions are represented by lichen planus and lichen striatus. They are characterized clinically by a papulous eruption, and histogically by a dermal superficial infiltrate of lymphocytic cells and a cytotoxic reaction directed against basal keratinocytes. The main differential diagnosis is hamartoma, the differentiation being important because of the possible association of haemartoma with malformations.

[Focal familial palmoplantar keratoderma with punctate hyperkeratosis of the palmar creases].

BACKGROUND: Keratosis punctata of the palmar creases is a variant of punctata palmoplantar keratoderma. CASE REPORT: Keratosis punctata of the palmar creases was observed in a 53 year-old North African male. The lesions presented as small keratotic papules confined exclusively to the flexion creases of the palms and digits, with a bilateral localization on the soles. The lesions were sensitive to pressure. The proband's 19 year-old son had similar lesions. DISCUSSION: Keratosis punctata of the palmar creases is characterized by the development of small round keratotic papules, electively and exclusively found in the palmar, digital, and uncommonly soles creases. The etiology is unknown. The frequency is higher in the black population. Although considered as an hereditary palmoplantar keratoderma with autosomal dominant transmission, familial cases with localizations on the soles is uncommon.

[Metastatic epidermoid carcinoma in idiopathic CD4+ T lymphocytopenia syndrome].

INTRODUCTION: Skin cancers are more frequent and more aggressive in immunosuppressed patients. CASE REPORT: A 58-year-old man was seen in January 1994 for squamous cell carcinoma of the right shoulder which had grown to 7 x 7 cm in the last 5 months. The patient had a past history of surgical exeresis of 5 squamous cell carcinomas and 3 basal cell carcinomas. Despite complete exeresis, the disease spread to localized then diffuse skin metastases. Acitretine and alpha-interferon were uneffective. Polychemotherapy stabilized the situation but several bronchopulmonary infections with atypical germs led to death (in February 1995). The patient had CD4 lymphocytopenia with a count < 100/mm3 in January 1994 of unknown origin (viral infection was eliminated). DISCUSSION: Our patient had idiopathic CD4 lymphocytopenia. In 40 p. 100 of the cases CD4 lymphocytopenia is caused by AIDS and in 53 p. 100 by other diseases, especially skin diseases including Kaposi syndrome, mycosis fungoides, squamous cell or basal cell carcinoma. The cutaneous carcinomas which often develop in AIDS patients with low CD4 counts are usually less aggressive than in our patient. Certain neoplasia could be the cause of the lymphopenia. CD4 counts are usually more variable and lymphopenia of shorter duration in other etiologies.
