- Abstract: Hypertrophic lichen planus (HLP) is a papulosquamous eruption presenting with extremely pruritic hyperkeratotic flat-topped papules, plaques, and nodules. This is a case of 38-year-old male who presented with a 2-month history of generalized erythematous-to-hyperpigmented papules, patches, and plaques topped with white-to-gray oyster shell-like scales on a background of hyperpigmented macules and patches. There was no involvement of the conjunctival, otic, oral, and genital mucosae, and palmar and plantar aspects of the hands and feet. Dermoscopy showed reticular pearly white structures corresponding to the Wickham striae, comedo-like openings, blue-gray dots, brownish-black dots, and scales. Histopathologic examination revealed marked compact hyperkeratosis, wedge-shaped hypergranulosis, irregular saw-toothed epidermal acanthosis, scattered dyskeratotic keratinocytes, and superficial perivascular lichenoid infiltrate of lymphocytes, histiocytes, and melanophages. The patient was managed as a case of HLP. He was started on methotrexate 10 mg per week, bath psoralen photochemotherapy (PUVA) three times a week, betamethasone valerate 1mg/g cream twice a day for 2 weeks alternating with tacrolimus 0.1% ointment twice a day for another 2 weeks, 10% lactic acid, emollients, and sunscreen. After 6 months of treatment, there was almost 80% improvement of lesions and relief of pruritus.
