Paraneoplastic pemphigus (PNP) is an autoimmune mucocutaneous blistering disease associated with neoplasms, most frequently of the lymphoproliferative type. Rare PNP cases related to nonhematological solid tumors have been reported. The patient in this report presented with severe mucocutaneous involvement of PNP associated with hepatocellular carcinoma. Histopathology showed vacuolar interface dermatitis with keratinocyte necrosis and intraepidermal acantholysis. Direct immunofluorescence exhibited deposition of intercellular IgG and complement and granular complement at the dermoepidermal junction. Indirect immunofluorescence testing showed a typical intercellular staining on monkey esophagus and rat bladder epithelium. Immunoprecipitation showed characteristic target antigens of 250, 210, and 190 kDa molecular weights. This patient met all diagnostic criteria for paraneoplastic pemphigus and is, to our knowledge, the first report of a case associated with hepatocellular carcinoma.

Background: Various types of brushes are efficient for the removal of foreign material accidentally projected into the skin by explosive or abrasive trauma., Objective: To evaluate how different times between injury and treatment influenced esthetic results, we retrospectively evaluated 14 patients subjected to the brushing technique., Methods: Two groups were identified. Group I had been treated within 24 hours of injury. In group II debridement had been performed later., Results: Cosmetic results were strikingly better in group I., Conclusion: Our results demonstrate that debridement of traumatic tattoos should be carried out as soon as possible to achieve favorable cosmetic results.
