Follicular Infundibulum Tumors

Tumors of the follicular infundibulum, also known as infundibular keratinizing acanthomas, are growths that develop in the hair follicles’ openings on the skin. While this condition may sound complex, we’ll break it down into easy-to-understand language. In this article, we’ll cover what these tumors are, their types, causes, symptoms, diagnostic tests, treatment options, and drugs that may be used. Our goal is to provide clear and accessible information to help you better understand this condition.
