Lichen myxedematosus in a patient with hepatocellular carcinoma

Lichen myxedematosus (LM) is a rare skin disorder characterized by waxy papules and skin thickening, often associated with monoclonal paraproteinaemia. In a reported case, a 50-year-old male with LM and hepatocellular carcinoma (HCC) experienced skin lesions and diminished hair growth. Following the surgical removal of a liver tumor, the patient's skin lesions improved, and eyebrow hair regrew without further treatment. Despite the surgery, the patient's polyclonal gammopathy remained largely unchanged. This case suggested a potential link between LM and HCC, with tumor resection leading to symptom improvement.
