Abstract:
Pityriasis versicolor is a common infection of the epidermis in adults, but only a few cases of this infection (especially the hypopigmented type) have been reported in infants aged under one year. Herein, we document a report of these cases and a review of the literature. Two patients with infantile pityriasis versicolor, who presented with hypopigmented macules on the neck, upper back, and chest are reported. A KOH examination was suggestive of pityriasis versicolor and our patients responded well to 1% clotrimazole lotion (twice a day) for four weeks. Pityriasis versicolor should be considered in the differential diagnosis of hypopigmented macules and patches in infants.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
