Abstract

Purpose of Review: The purpose of this review was to explore mechanisms, causes, and therapies of itchy conditions involving organs beyond the skin including the eyes, ears, nose, and genital region. Recent Findings: Conditions which cause itch in these locations vary from skin diseases that extend to these areas (i.e., atopic dermatitis, seborrheic dermatitis, and psoriasis) to allergic conditions (i.e., allergic rhinitis and conjunctivitis) and to neuropathic conditions that relate to afferent nerve fiber damage (i.e., lumbosacral radiculopathies in genital disease) as well as some psychological components. Similar to the skin, itch in these locations involves a complex interaction between epithelial cells, unmyelinated C nerve fibers, and cytokines. There is also a significant component of neural sensitization phenomena. Summary: Mechanisms of itch beyond the skin are currently an understudied topic that affects millions of patients. Future research should be done in order to further understand the pathophysiology of itch in these body sites.
