Ichthyosis refers to a group of genetic skin disorders characterized by dry, thickened, and scaly skin. These conditions vary in severity and can affect different parts of the body. This clinical vignette on ichthyosis aims to assist residents in recognizing and diagnosing these diverse skin disorders. Through this case, users will learn about the clinical features of ichthyosis, its differential diagnosis, and appropriate diagnostic and management strategies.

This vignette is an excellent resource for residents preparing for OSCE-style examinations and can also be used as a self-directed learning tool for healthcare professionals seeking to enhance their knowledge and skills in managing ichthyosis.

We invite you to explore the associated learning module and quizzes to reinforce your knowledge and test your understanding of this important topic.
