Surgical Treatment by Partial Petrosectomy for a Middle-Ear Carcinoid with Progressive Extension: A Case Report and Review of the Literature

We herein report a 59-year-old male patient with a recurrent carcinoid tumor of the middle ear 7 years after a tympanomastoidectomy. The CT and dynamic MRI demonstrated an extensive tumor close to the carotid artery canal and the jugular bulb, and the tumor was removed by a partial petrosectomy with a transmastoid approach. The histopathological findings revealed a solid and trabecular tumor with cells positive for cytokeratin, chromogranin A, synaptophysin, and CD56. The MIB-1 antibody for the Ki-67 antigen was positive in 6.6% of the tumor cells. The relevant literature is reviewed in regard to the present case

Histological Remission during Corticosteroid Therapy of Overlapping Nonalcoholic Steatohepatitis and Autoimmune Hepatitis: Case Report and Literature Review

Concurrence of nonalcoholic steatohepatitis (NASH) with autoimmune hepatitis (AIH) is a rare condition that is challenging to diagnosis, due to the relatively high prevalence of autoantibodies in NASH. It is also difficult to determine the most effective treatment as corticosteroids are likely to worsen NASH despite being effective in the treatment of AIH. In this case report, we present a female diagnosed with NASH-AIH overlap with accompanying diabetes mellitus, who successfully achieved normalization of serum alanine aminotransferase levels following prednisolone therapy and weight loss. A follow-up liver biopsy performed 40 months after the initial diagnosis showed only minimal inflammatory infiltrates in the portal area without any NASH histology. Resolution of NASH, in conjunction with a reduction in hepatic fibrosis, might suggest that prednisolone itself does not aggravate steatohepatitis, but rather prevents disease progression. Appropriate immunosuppressive treatment may therefore be an important component of the optimum therapy for NASH-AIH overlap
