Immunohistochemical analysis of lichenoid reactions in patients treated with anti-PD-L1 and anti-PD-1 therapy J Cutan Pathol . 2016 Apr;43(4):339-46. doi: 10.1111/cup.12666.

2021-01-30 · Lichenoid dermatitis is an allergy that forms on the skin and causes a purple, itchy rash. It is caused by damage to the epidermis, which results in inflammation and problems with how the outer layer of skin interacts with the next inner layer of tissue, called the dermis. Lichen planus (LP) is a mucocutaneous disease with well-established clinical and microscopic features. The oral mucosa and skin may present clinical and microscopic alterations similar to those observed in LP, called lichenoid reactions (LRs), which are triggered by systemic or topical etiological agents. Definition Lichenoid reactions are a heterogeneous group of lesions of the oral mucosa that show clinical and histopathological similarities to lichen planus, but have a different course.

It is caused by damage to the epidermis, which results in inflammation and problems with how the outer layer of skin interacts with the next inner layer of tissue, called the dermis. Lichen planus (LP) is a mucocutaneous disease with well-established clinical and microscopic features. The oral mucosa and skin may present clinical and microscopic alterations similar to those observed in LP, called lichenoid reactions (LRs), which are triggered by systemic or topical etiological agents. Definition Lichenoid reactions are a heterogeneous group of lesions of the oral mucosa that show clinical and histopathological similarities to lichen planus, but have a different course. Etiology Hypersensitivity to dental restorative materials, amalgam, composite resins and dental plaque accumulation are the most common causative factors. Lichenoid drug eruptions (LDE) are usually pruritic. The onset may be within weeks of drug initiation, but LDE is atypical in that it can take up to 12 months to evolve.

2015-09-01 · In case of suspected delayed-type hypersensitivity reactions, epicutaneous patch testing is recommended. 56 When assessing for oral contact allergy to metals, late readings up to 10 days should be considered because some reactions may not occur as early as expected. 57 Eventual positive reactions must be thoroughly evaluated for their clinical relevance. 58 In the case of lichenoid contact

2014; 23(7): 14 | 11: Lichenoid contact reaction to eugenol presenting as oral lichen planus The search words included oral lichen planus, oral lichenoid lesions, oral drug reactions, lichenoid dysplasia, and adverse effects of dental materials. Review Results: OLLs seem to grossly underrated and most cases were clubbed as OLP. Definite clinical and histological features were uncovered to establish the identity of this lesion. The lichenoid reaction pattern (lichenoid tissue reaction, interface dermatitis) is characterized histologically by epidermal basal cell damage. 1. 2. and 3. This takes the form of cell death and/or vacuolar change (liquefaction degeneration).

58 In the case of lichenoid contact Lichenoid tissue reaction or interface dermatitis embrace several clinical conditions, the prototype of which is lichen planus and its variants, drug induced lichenoid dermatitis, special forms of Lichenoid granulomatous reaction can be subcategorized into lichenoid granulomatous dermatitis or lichenoid granulomatous stomatitis. It is described in the literature as demonstrating a band‐like lichenoid infiltration with clusters of histiocytic or granuloma formation. Levothyroxine-associated lichenoid drug eruption: A case report and review of levothyroxine-induced adverse reactions Levothyroxine (LT 4) is frequently used as thyroid hormone replacement to treat hypothyroidism.

1 It can be considered as a separate disease or as an exacerbation of already existing OLP, by intake of medication or presence of dental material. 2,3 In recent consensus, oral as well as cutaneous involvements has been reported.

Amalgam-associated oral lichenoid reaction (AAOLR) is a rare lesion in dental practice. This article presents a case involving a striated, white, symptomatic plaque with an atrophic central area located in the left buccal mucosa and making direct contact with an amalgam restoration.

A: In 1978, Krutchkoff and associates, re-examined 223 cases of OLP that were reported to have become malignant.

Lichenoid drug eruptions (LDE) are usually pruritic. The onset may be within weeks of drug initiation, but LDE is atypical in that it can take up to 12 months to evolve. A latent period of 3 years has been reported with penicillamine. LDE from ACE inhibitors typically takes 3 to 6 months to appear.
