Clinical and laboratory presentation of lichen planus patients with chronic liver disease.

A recent case-control study on 577 lichen planus (LP) patients and 1008 controls confirmed that LP patients may significantly associate with a chronic liver disease (CLD) which is independent from drug or alcohol intake and has some connection with hepatitis B virus (HBV) infection. The study, however, failed to define the nature of CLD. This has been investigated through the clinical and laboratory features of 50 patients with LP and impaired liver function tests. Overall, the laboratory signs of cell necrosis prevailed over those of cholestasis and a good relationship with the HBV and HCV infections was found. Ninety percent of patients with LP and CLD had antibodies to one or another of the major viruses involved in infectious hepatitis. No patient had anti-liver kidney microsomal antibodies type 1. Liver biopsies were done in 12 cases and mostly revealed a chronic active hepatitis evolving into cirrhosis. No evident cases of primary biliary cirrhosis were found. It appears that LP associated CLD is post-viral in nature.

Lichen planus, liver kidney microsomal (LKM1) antibodies and hepatitis C virus antibodies.

No anti-liver kidney microsomal (LKM1) antibodies were detected in 46 patients with LP, 16 of whom had also a chronic liver disease (CLD). In contrast, anti-hepatitis C virus (HCV) antibodies were found in 10% of patients with LP and in 50% of those with LP and CLD. Anti-HCV antibodies may be considered as a false-positive reaction in 56% of cases, especially when anti-LKM1 antibodies are present. Our findings do not support such a hypothesis, but suggest that CLD in LP patients is, at least in Italy, mostly a postviral chronic active hepatitis.

Prognosing melanomas: the argyrophilic nucleolar organizer region approach.

Staining of argyrophilic nucleolar organizer regions (AgNORs) is a histological technique that has been assayed on a vast array of cutaneous tumors in order to help distinguish benign from malignant lesions. In a number of papers, malignant melanomas have been found to have a higher number of black nucleolar and extranucleolar dots (i.e. AgNORs) than benign nevi, including Spitz nevus. The technique may be used for prognostic purposes, as a recent paper suggests. Melanomas with more than 3.62 AgNORs/cell have a higher probability to develop metastasis than melanomas with fewer AgNORs. The problems such an apparently simple, fast and reproducible technique may pose are discussed in detail.

Hepatocellular carcinoma and lichen planus: report of two cases.

A patient with lichen planus (LP) who developed a hepatocellular carcinoma as a consequence of a postviral chronic hepatitis is described. Its possible noncoincidental association with LP is discussed on the basis of a recent large case-control study in which the association of LP with chronic, possibly postviral, liver disorders has been confirmed. In the same study 1 case out of 577 LP patients was found to have hepatocellular carcinoma versus none of the 1,031 controls, a prevalence which is higher than expected in a western population.

Epstein-Barr virus-related persistent erythema multiforme in chronic fatigue syndrome.

BACKGROUND: Erythema multiforme (EM) has been rarely reported in Epstein-Barr virus (EBV)-associated diseases; this includes patients with chronic fatigue syndrome who have chronic or recurrent and disabling illness and an abnormal antibody reactivity to EBV. We describe a patient fulfilling the chronic fatigue syndrome diagnostic criteria who had developed an unusually persistent EM resistant to corticosteroids therapy. The EBV DNA was studied in skin EM lesions, throat washings, peripheral mononuclear cells, and plasma. The EBV antigens were studied in skin EM lesions and in mononuclear cells. The patient was followed up to 2 years. OBSERVATIONS: The patient had abnormal titers of antibodies against various EBV antigens and by immunofluorescence she disclosed the EBV nuclear antigen and the viral capsid antigen in the blood vessels of the affected skin. The dot blot hybridization assay detected viral DNA in throat washings and mononuclear cells, but not in plasma. The presence of the viral genomic content in lesional skin is suggested by the autoradiographic signal and by the difference from appropriate control specimens. Skin lesions and constitutional symptoms cleared after acyclovir sodium therapy and recurred after discontinuation of this therapy. CONCLUSIONS: This is the first EM case in which evidence of the EBV causal role has been provided. The association with chronic fatigue syndrome suggests the EBV role in selected cases of this syndrome.
