Keratosis lichenoides chronica: a case report with dermatoscopic and ultrasonographic analysis

Year: 2025

Type: article

Abstract: We present the case of a 46-year-old woman with a long-standing history of linear erythematosquamous papules on the arms and thighs, which were unresponsive to treatment with topical corticosteroids. She also reported lesions typical of seborrheic dermatitis located on her face. After performing a clinical examination, dermatoscopy, high-frequency ultrasonography (HFUS), and a biopsy for histopathological examination, a diagnosis of keratosis lichenoides chronica (KLC) was obtained. Also known as Nekam disease, KLC is a rare, chronic inflammatory skin disease characterized by diffuse, linearly arranged erythro- or erythematosquamous papules with a thin, keratotic plug.
