Objective To improve the diagnosis and treatment of hepatic angiomyolipoma. Methods Retrospective analysis was made on 8 cases of hepatic angiomyolipoma in terms of clinical findings,image,pathologic examination and surgical treatment.Results Correct preoperative disgnosis was made in only 1 case, 4 were misdiagnosed as malignancy. All 8 cases underwent hepatectomy with an uneventful recovery and without recurrence at follow up.Conclusions Hepatic angiomyolipoma is characteristic of clinical as well as image features, although it is often difficult to make correct diagnosis before operation owing to low incidence and variable imaging appearances.

Objective: To investigate treatment and outcome of rib cartilage framework in ear reconstruction. Methods: 12 cases of rib cartilage framework infection in ear reconstruction were retrospectively analysed in the latest four years. Lab examination results showed that staphylococcus aureus were found in 5 cases, coagulase negative staphylococcus in 3 cases, Klebsiella pneumonia in 2 cases, aeromonas hydrophila in 1 case and no bacteria were found in 1 case with regular culture. Debridement, systemic antibiotic therapy, saline irrigations and unobstructed drainage were utilized to treat the infection. Results: The average duration of dressing change was 35 days in 12 cases (12-67 days), of which six cases were cured leaving no obvious or mild change of cartilage framework. Cartilage framework was totally damaged by infection in one case, so the framework had to be removed and debridement was then carried out to control infection. Secondary repair should be taken at least 6 months later. In the rest 5 cases, frameworks were taken out in the early stage of infection. The infected portion of the cartilage was removed and the healthy part was buried subcutaneously in the chest. The expanded postauricular flap and fascia were smoothened. Secondary repair should be performed after 6 months. Conclusions Effective debridement, irrigations and drainage can be used to control infection of cartilage framework and maintain normal contour and structure of reconstructed auricle. With regards to severe infection, framework should be removed as early as possible and infected portion of cartilage should be cleared out, while healthy part could be used for secondary reconstruction of auricular contour after complete control of infection.
