rounding skin. As the desquamation proceeded outward, the areas developed a characteristic
appearance of a central depigmented area fringed with a hyperpigmented zone. At u later stage,
pigmentation began in the central areas and spread outwards. After a few weeks the cycle was
completed, leaving in most instances a relatively normal appearing skin.

However, an the feet, some large
bullae (blisters) appeared. After a few days, the hyperpigmented lesions showed wet desquiumnation with weeping and crusting, leaving depigmented raw surfaces of varying area, Some of
these lesions became secondarily infected. Epithelium rapidly covered the ulcerated areas
within a week to 10 days. Pigmentation followed during the next few weeks. As healing occur-
red many of the more severe lesions (particularly on the neck and antecubital fossae) developed
a thickening of the skin with an “orange peel” appearance and a dusky, grayish-brown color
{see Plate 3.4).
