Contact dermatitis to PPD rubber in Maleki shoes.

The Persian cloth shoe (Maleki) which has been in use for more than 800 years has a strong cloth sole and a woven cotton upper. In the last 20 years, used car tires have become readily available in Iran and the soles of some shoes are now made from these. A man with the typical picture of rubber dermatitis on the soles of his feet is described. On patch testing he gave a 2+ positive to PPD rubber and this was thought to be due to the fact that he had worn Maleki shoes for several years.

The natural history of trichilemmal cysts.

The histological features of 149 trichilemmal cysts removed from sixty-five patients are reviewed and related to the clinical findings. These cysts, which may be solitary or multiple, gradually increase in size and number, and may produce daughter cysts by budding. When a breach occurs in the wall, inflammatory cells pour in but do not replace the cyst wall. This event may be followed by healing from the margins of the breach, by marsupialization to the overlying epidermis and thus natural resolution, or by proliferation to produce a pseudo-epitheliomatous change which can be confused with a well differentiated squamous cell carcinoma.
