Solar keratoses and their relationship to non-melanoma skin cancers.

Solar keratoses belong to the list of clinically invisible dermatoses, as the loss of their horny layer may create the illusion that they have disappeared, and numerous subclinical lesions can be highlighted by 5-fluorouracil therapy. Solar keratoses are recognized as potential precursors for squamous cell carcinoma. However, basal cell carcinoma (BCC) may develop in a soft type of solar keratoses as a consequence of migration of pluripotential adnexal epithelial cells in reparative response to trauma, particularly in areas rich in adnexal structures, such as the face. These intraepithelial resident adnexal cells may result in the development of BCC following chronic solar exposure and damage.

Eruptive infundibulomas. A distinctive presentation of the tumor of follicular infundibulum.

Hundreds of asymptomatic pale erythematous lesions, 2 to 15 mm in diameter, with complex angulated shapes in a mantle distribution over the upper portion of the chest and back and the shoulders, developed in two unrelated young men. Actinic porokeratosis, discoid lupus erythematosus, pityriasis versicolor, and acne scars were considered as possible diagnoses, but none of these appeared appropriate. Multiple skin biopsy specimens from both patients showed tumors of follicular infundibulum (infundibulomas), benign platelike proliferations of the external root sheath that were outlined by a prominent brushlike elastic network. This presentation of the tumor of follicular infundibulum can be recognized by its unusual clinical pattern and histopathology.

[Symmetrical lividity of the fingers].

Symmetric lividity of the soles of the feet was first reported in two children in 1925 by Pernet. The characteristic manifestation of this dermatosis consisted in hyperkeratosis and hyperhidrosis with livid discoloration of the pressure areas of the soles. Later the same name was applied to a similar dermatosis in which the hyperkeratotic and hyperhidrotic patches of skin on the soles had a whitish grey discoloration and the livid color, if present at all, was seen only over the marginal areas not affected by the keratosis. Similar livid keratoses affecting the palmar sides of the fingers have been seen only occasionally. The 17-year-old girl presented in this paper had a 11-year history of emotional hyperhidrosis and is a rare illustration of symmetrical lividity in its original form, localized to the fingers only.

Micropapular sarcoidal facial eruption in a child: Gianotti-type perioral dermatitis.

The case is described of a boy aged 13 years reported with a diffuse facial micropapular eruption which had a granulomatous histology. The diagnosis is consistent with perioral dermatitis of the Gianotti type (4, 5). It is postulated that bubble gum was the cause of the condition, the most likely ingredient being the essential oils in the gum, which may actually be selectively absorbed by the follicle to produce a perifollicular granulomatous reaction. In this article we have added yet another possible cause for perioral dermatitis.
