Psoriasis and drugs: influence of tetracyclines on the course of psoriasis.

Patients with psoriasis vulgaris (462) were studied by questionnaire to find the effect on psoriasis of drug therapy for intercurrent diseases or focal infections. Of 462 patients with psoriasis, in 76 (16.45%) the disease became more severe during drug therapy. Of these, 19 worsened after administration of tetracyclines, and in five psoriasis was precipitated after therapy with drugs of the tetracycline family. We suggest that tetracyclines should be avoided in patients with psoriasis and in healthy persons with a genetic predisposition (positive family history, human leukocyte antigens B13, B17, B27).

Generalized acanthosis nigricans.

A patient suffering from an advanced and inoperable gastric carcinoma developed an unusual paraneoplastic syndrome, consisting of intensive pruritus, acanthosis nigricans, sign of Leser-Trélat (seborrhoic keratoses and freckles), warty and papillomatous excrescences, palmoplantar hyperkeratosis and florid papillomatous and granular lesions of the mouth mucosa. The whole skin of the patient was involved. The authors believe this disorder to be generalized acanthosis nigricans. As a cause they suggest the possibility of a growth-stimulating factor, produced by the tumor cells. The relationship of acanthosis nigricans with the sign of Leser-Trélat is discussed.
