Lichenoid eruption

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.
