Tropical Ulcers

Tropical ulcers, also known as tropical skin ulcers or Malabar ulcers, are open sores that occur in tropical and subtropical regions. These ulcers can be caused by various factors, and understanding their types, causes, symptoms, diagnostic tests, and treatments is essential for effective management. In this comprehensive guide, we break down the complex medical jargon to provide simple, easy-to-understand explanations.

Types of Tropical Ulcers:

Tropical ulcers can be broadly categorized into the following types:

1. Chancroid Ulcers:
