Case history
Case history
A 50-year-old woman presents with persistent, intensely pruritic, cutaneous lesions on the flexor wrists and ankles. Eruption was spontaneous and treatment with over-the-counter hydrocortisone cream and emollients were unsuccessful. On examination there are several discrete, violaceous, polygonal, flat-topped papules and plaques with overlying white reticulated scale. Onychodystrophy is also apparent. No excoriation marks are visible. Examination of the mouth reveals lacy change in the left buccal mucosa.
Other presentations
Lichen planus (LP) may present after hepatitis B, inactivated influenza, or coronavirus disease 2019 (COVID-19) vaccination.[16][17][18]
LP may also present as lichen planus pemphigoides. This is a relatively rare condition, distinct from bullous lichen planus, and represents an overlap between lichen planus and a group of sub-epidermal blistering diseases.
A crossover condition of LP and lupus erythematosus has been described. This may present as LP lesions in a photodistribution (at sites routinely exposed to the sun) with or without other signs of lupus erythematosus.[19][20]
