Immunosuppression and transplantation have been reported to induce porokeratosis (PK), especially its variant, disseminated superficial PK (DSP). On the other hand, there is ample evidence of a relationship between hepatitis C virus (HCV) infection, liver cirrhosis (LC), and hepatocellular carcinoma (HCC). We report 3 cases of DSP in which the outbreak of DSP was suspected to have occurred during the development of HCC in patients with HCV-positive LC. The patients had undergone ultrasonographic study regularly, and no signs of malignancy had been found before the development of DSP. Their outbreaks of DSP were very acute, and the period between the development of DSP and diagnosis of HCC ranged from 2 to 6 months. The association of HCV-related HCC and DSP has never been previously reported. HCV-induced immunomodulation or its effect on the p53 system may be the basis for this type of association. It is necessary to consider development of HCC whenever DSP is found in HCV-positive patients. DSP may be a new paraneoplastic dermadrome.

Disseminated superficial porokeratosis has been described in the setting of immunosuppressive conditions, including organ transplantation, infections, and hematopoietic malignancies. The outbreak of disseminated superficial porokeratosis during the development of solid organ malignancies has been rarely reported in the literature in patients affected by hepatitis C virus-related hepatocellular carcinoma or by cholangiocarcinoma, which suggests a paraneoplastic nature of the cutaneous disease. We report an unusual case of disseminated superficial porokeratosis in a patient affected by ovarian cancer, characterized by simultaneous onset and a parallel course of the two pathologies; there was good clinical response to chemotherapy, accompanied by a successful stop of disseminated superficial porokeratosis progression and gradual clearing of the keratotic lesions.
