Keratosis lichenoides chronica (KLC) is a rare chronic dermatosis characterized by lichenoid hyperkeratotic papules arranged in a linear and reticular pattern, and seborrheic-dermatitis-like lesions on the face. Less frequently, palmoplantar keratoderma, nail dystrophies, mucosal as well as eye lesions are present. KLC affects adults and very few cases have been reported in childhood. Although infrequently, KLC has been associated with systemic diseases, including chronic infectious diseases, kidney disorders and lymphoma. Here we report the case of an adult KLC patient with skin, nail and mucosal involvement, and onset in the first year of life who developed a leg panniculitis and a mantle cell lymphoma. Following chemotherapy for the lymphoma, panniculitis resolved completely, and skin and mucosal KLC lesions ameliorated.
