Lichenoid eruptions appearing in two women receiving chrysotherapy (Solganal B oleosum R) a described. The morphological diagnosis, distribution of skin eruptions, histological and immunological features and monoclonal antibodies (Leu 4, Leu 2A and Leu 3A) against several cell surface markers were studied. Individual lesions were not distinguishable from idiopathic lichen planus, with some features typical for gold lichenoid eruptions: hyperpigmentation, psoriasiform eruptions, and hair loss. Histopathological and immunological examination of biopsy specimens with monoclonal antibodies generally confirms clinical impressions. The authors suggest similar pathogenetic mechanisms in the development of idiopathic lichen planus and of lichenoid eruptions after gold therapy.

Lichen planus is a chronic skin lesion characterized by pruritic violaceous papules, which has a high risk of morbidity. Skin microbiota plays an important role in the maintenance of cutaneous mucosal barrier and human health and immune homeostasis. Studies have shown that skin microbiota may play a role in the pathogenesis of lichen planus, but it is not yet clear.

Mucosal-associated invariant T (MAIT) cells, a type of T lymphocytes with innate-like characteristics, are crucial in bridging innate and adaptive immunity. When activated, MAIT cells release various inflammatory molecules and swiftly respond to antigens. Notably, numerous studies highlight the significant impact of MAIT cells on tumors and various immune disorders by influencing the immune microenvironment.
