Abstract:
Rural dermatology in the tropics is determined by socioeconomic factors, climate, and skin type. Lack of interest of the profession leads to late and inadequate diagnosis and treatment. No proper data on the magnitude of the problem are available, even though a great number of the world population live under those conditions. This contribution provides an overview of the most common skin diseases, in particular, infections and infestations. Other skin conditions, both eczematous and immune-mediated, that are typical for the rural tropics also are discussed. Etiology, pathology, and treatments are presented against the socioeconomic background.

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.
