[Impetigo herpetiformis (two cases)]. / L'impétigo herpétiforme (deux cas).

UNLABELLED: The hepetiformis impetigo is a pustulosis dermatosis. It is rare and specific to pregnancy. It can menace the prognostic of the mother and the child. This entity is actually considered as a pustulor psoriasis. We report two cases. CASES REPORTS: Two patients, respectively, aged 24 and 21, presented erythematous, pustular and extensive plaques for which the diagnosis of hepetiformis impetigo was clinically and histologically posed. For the first patient, the lesions appeared in the two pregnancies and were more severe and foetal repercussions (oligoamnios and hypotrophy) during the second pregnancy. For the second patient, the pregnancy was complicated with premature interruption of the membrane, giving birth to a deed fetus and causing an aggravation of the cutaneous lesions. The treatment was oral steroid followed by acitretin for the first patient, however, for the second patient; the treatment was by local steroid associated with UVB during the pregnancy. Then, acitrétine was used and was efficient. CONCLUSION: Our two cases show the importance of gynaecological control in order to avoid complications which can be sometimes fatal. They also show the importance of local steroid associated with UVB which constitute another therapeutic alternative in the treatment of hepetiformis impetigo.

[Bleomycin induced flagellate erythema]. / Le cas clinique du mois. Erythème flagellé induit par la bléomycine.

Bleomycin is an antibiotic with antineoplastic pro prieties. It is used in the traitement of many syndromes. The cutaneous toxicity of bleomycin includes many alteration. We report a case of flagellate erythema following the administration of bleomycin in a 57-year-old women with Kaposi sarcoma. She developped linear lesions 6 days after the first dose of bleomycin. Flagellate erythema is a specific reaction to bleomycin therapy wich occurs in susceptible individuals independently of dose, route of administration and type of malignant disease treated. Its occurs in 10 to 35% of the treated patients.

[Radiotherapy-induced pemphigus: a case report]. / Pemphigus induit par radiothérapie: à propos d'un cas.

A 61-year-old male patient suffering from squamous cell carcinoma of the lower lip developed pemphigus vulgaris two months after exposure to radiotherapy. Skin lesions were initially localised to the face and neck and later extended over other skin areas. The eruption are improved with glucosteroid therapy, which were stopped after six months. Pemphigus induced by radiotherapy is rare, latency before the onset of the vesiculobullous eruption is variable. Clinical, histological and immunological characteristics are similar to those of other types of pemphigus.

[Squamous cell carcinoma complicating an hereditary epidermolysis bullosa]. / Carcinome spinocellulaire compliquant une épidermolyse bulleuse héréditaire.

The dystrophic form of hereditary epidermolysis bullosa is associated with an increased frequency of squamous cell carcinoma. We report a new case. An 18-year-old patient, carrying a Hallopeau Siemens hereditary epidermolysis bullosa, presented a subcutaneous nodular lesion, for 1 year that ulcerated and budded with inguinal lymphadenopathy. The histological study led to the conclusion of a well differentiated squamous cell carcinoma. The patient was treated surgically. Tumor and metastatic lymph nodes were excised. A radiotherapy was decided but the postoperative course was fatal due to an infection and to a deterioration of her general condition. Squamous cell carcinoma frequently occurs on the cicatricial lesion of hereditary epidermolysis bullosa and usually affects males with recessive hereditary epidermolysis bullosa. Metastases are frequent, precocious and multiple. The treatment may be surgical. The particularities of our observation are the young age of patient and the localization.
