A 25-year-old woman came with an itchy red rash on her back since 2 years ago. This lesion then extended to the abdomen, arms and legs. From the patient’s back, we found irregular linear hyperpigmented patches with some of the edges in the form of hyperpigmented plaques. On the abdomen, arms and legs, erythema-hyperpigmented plaque and patches were visible along the elevated edges with multiple scattered sizes. Lichen planus (LP) has several types based on various clinical manifestations. The diagnosis of LP can be made based on the clinical appearance and symptoms of pruritus. Many diseases can mimic other diseases so histopathology is used to make the diagnosis. Here, we report a case of LP with unusual features with diagnosis confirmed by histopathological examination. The patient was treated with oral and topical potent corticosteroids with good response.

Annular lichenoid diseases have many differential diagnoses. Lichen planus (LP) and porokeratosis could show annular-shaped lesions with a lichenoid tissue pattern infiltration, but typical cornoid lamella formation is mainly in favor of porokeratosis. We present a 57-year-old man with papulovesicular and annular lesions on the shins with an exophytic lesion of left great toe nail. Papular lesions showed classic histopathology of LP, but annular lesions revealed imperfect cornoid lamella formation that could be seen in the porokeratotic variant of LP. Nail bed biopsy showed in-situ squamous cell carcinoma and so distal phalangeal amputation was performed. Our patient had no good response to topical and systemic steroid, but he had moderate improvement with oral retinoid. We think that our case had different types of LP including classic, bullous and porokeratotic variants which is a rare association.
