Role of anxiety and anger in acne patients: a relationship with the severity of the disorder.

Studies investigating the possible role of personality and emotional factors in acne patients have yielded inconsistent and sometimes contradictory results. In the present study acne patients self-rated the severity of their conditions as mild, moderate, or severe and were compared to a control group on several personality variables. These self-ratings were compared to the objective ratings made by their dermatologists.

Contact dermatitis caused by Brucella.

We report a case of a distinctive dermatitis in a dairy worker exposed to Brucella abortus while manually delivering an infected calf. The rapid onset of pruritus, the strict limitation of lesions to the upper extremities, and the negative results on growth of culture for microorganisms make direct bacterial infection an untenable cause in this case. Allergic hypersensitivity is the probable mechanism, manifesting itself initially as contact urticaria.

Tumor of the follicular infundibulum.

A histopathologically unique tumor originating from the infundibular portion of vellus hair follicles is presented and the clinical and microscopic features of such a case are described. A superficial subepidermal shelf of trichilemmal structure differentiates the lesion from the lobular acanthosis of trichilemmoma.
