ON SYMMETRICALLY GROUPED COMEDONES.

On Symmetrically Distributed Random Measures

A random measure ~ defined on some measurable space (S,S) is said to be symmetrically distributed with respect to some fixed measure w on S, if the distribution of (~Al, ... ,~Ak) for kEN and disjoint AI" .. ,AkES only depends on (wAl, ... ,wAk). The first purpose of the present paper is to extend to such random measures (and then even improve) the results on convergence in distribution and alm...

Perianal Comedones: A Rare Incidental Finding

Comedones occur when an overproliferation of keratinocytes blocks sebum secretion in a pilosebaceous duct. Comedones have multiple possible etiologies and contributing factors. While comedones are common to acne, they are also seen in occupational exposures and are associated with certain syndromes. We describe a particularly rare case of comedones at the perianus that is not associated with an...

Childhood flexural comedones: a new entity.

BACKGROUND Comedones are usually found in acne and involve the seborrheic areas of the skin. Disseminated comedones can be found in other skin disorders. Flexural comedones are characterized by double orifices connected by a thin layer of epidermis that reveals the comedo content below it. To the best of our knowledge, flexural comedones have not been previously described as an entity. Our obje...

Psoriasin and follicular hyperkeratinization in acne comedones.

pathological circumstances [5] . In the meantime, psoriasin has been suggested to be involved in the pathogenesis of inflammatory skin diseases, and its levels were found to increase in response to inflammatory stress. In addition, retinoic acid (RA) and inflammatory agents have been implicated in the upregulation of psoriasin [6, 7] . Psoriasin was shown to be induced not only in psoriatic epi...
