The authors present a follicolitis and perifolliculitis case with abscess and profound nodules, unfolded on a patient who had been subjected to an abusive local an general treatment with corticoids.

The allergological study could prove a depression of the cellular immunity, but at the same time it demonstrated an abnormal reaction, as an anaphylactoid one, at trychophytin and penicillin.

[Epidermal peripilar nevus].

A classic case of Epidermal Nevus with a particular peripilar arrangement is presented. Histopathologically, acanthosis, hyperkeratosis and papillomatosis is observed. The indemnity of the hair appendages was demonstrated in three biopsies.

[Variable pseudoerythroplasic telangiectasis balanitis].

This is a special case of balanitis, that authors separate from entities clinically established such as Erthroplasie of Queyrat, Balanitis of Zoon, Liquenoide Balantis with Plasmocytes and the Balantis of Sulsberger and Garbe's illness. The V. P.
