Lichenoid eruption

Medical condition

Lichenoid eruption

Histopathology of lichenoid drug reaction. It resembles lichen planus because of irregular epithelial hyperplasia, focal hypergranulosis, orthokeratosis, and a “saw-tooth” pattern of rete ridges.
Specialty| Dermatology

A lichenoid eruption is a skin disease characterized by damage and infiltration between the epidermis and dermis.[1]

Examples include lichen planus, lichen sclerosus and lichen nitidus. It can also be associated with abrasion or drug use.[2] It has been observed in conjunction with the use of proton pump inhibitors, and might be a sign and/or symptom of lupus such as subacute cutaneous lupus erythematous, according to the case reports and reviews.[3][4][5][6]

The term "lichenoid" derives from a resemblance to a lichen.
