Follicular cysts in dogs are large nodules or bumps that develop on the skin. These cysts originate from the hair follicles and can contain a thick, white, yellow, or brown material. As they grow, they may become itchy or painful. While most dogs typically have one follicular cyst at a time, some may have multiple cysts simultaneously. These cysts are also known by other names, such as isthmus or tricholemmal cyst, infundibular cyst, matrical cyst, and hybrid cyst.
How Are Follicular Cysts Found?
Diagnosis of follicular cysts involves taking skin samples and examining them under a microscope. This may be done through a fine needle aspirate or by surgically removing the entire cyst (biopsy), especially if the cyst is growing or causing discomfort.
What Does Treatment Involve?
Follicular cysts are generally not known to spread beyond the skin, but they can become infected. In cases of infection, a skin culture may be performed to determine the appropriate antibiotic treatment. If a follicular cyst grows in size and causes discomfort, surgical removal may be recommended. Once a follicular cyst is removed, it typically does not regrow.
