Anaplastic carcinoma of the thyroid gland (ACT) is a rapidly growing neoplasm with a very poor prognosis. In this study, we examined an ACT with osteoclast-like giant cells expressing matrix--degrading cysteine proteinases and their endogeneous inhibitor cystatin C. Bronchoscopic evaluation of a 50-year-old man suffering from hoarseness, dysphagia, and dyspnea revealed an irregular tumor mass infiltrating into the trachea and the cricothyroid ligament region. On histological examination, a necrotizing undifferentiated anaplastic carcinoma with osteoclast-like giant cells was detected. An immunohistochemical study of the tumor tissue was performed using a panel of 15 antibodies, including double labeling techniques. Most of the osteoclast-like multinucleated giant cells (MGC) expressed CD68 and cathepsin K. Colocalization of cathepsin B and its endogenous inhibitor cystatin C occurred in the majority of MGC. Mononuclear cells (MC) were positive for cathepsin B, cystatin C, and CD 68, but only faintly for cathepsin K. Expression of cathepsins B and K in the MGC of the ACT might contribute to the invasive behavior of this tumor, thus promoting metastatic ability and destruction of the cartilagenous trachea.

We observed two families with a dominantly inherited complex neurological syndrome with onset in adulthood. Family F included 9 affected in four generations. One patient showed prominent anticipation of onset age. Onset was with cerebellar signs followed by dementia, psychiatric symptoms, seizures, and extrapyramidal features. Family M included 14 affected individuals in five generations. Presenting symptoms were either psychiatric and cognitive impairment or a cerebellar syndrome. Extrapyramidal features, dysphagia, incontinence, seizures, and myoclonus may occur. In both families magnetic resonance imaging showed marked atrophy of the brain and cerebellum. Molecular analyses demonstrated an expanded CAG/CAA repeat in the in the TATA box-binding protein (TBP) gene (SCA17).
