ABSTRACT
Extragonadal germ cell tumors are rare and comprise 2-5% of all germ cell tumors. Seminoma/dysgerminoma, teratoma, yolk sac tumor (YST) and mixed germ cell tumors are few of the extragonadal germ cell tumors arising within the brain. Of these, primary pure YSTs arising in the brain are extremely rare and arise in the pineal (62%) and suprasellar (31%) regions. Primary YST occurring in the cerebellum is exceedingly rare, associated with a very poor prognosis and has been reported in less than 10 cases in literature. We herein report a case of primary pure yolk sac tumor in the cerebellar vermis in a 2-year-old child.
ABSTRACT
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized by progressive fibrofatty replacement of the myocardium that predisposes to ventricular tachycardia and sudden death in young individuals and athletes. The prevalence of ARVD/C is estimated as 1:1000 to 1:1250 in the general population. Although it is a relatively uncommon cause of sudden cardiac death, it accounts for up to one fifth of sudden cardiac death in people less than 35 years of age. Clinical presentation of ARVD/C usually consists of arrhythmias of right ventricular origin that include premature ventricular beats, sustained ventricular tachycardia and ventricular fibrillation that can lead to sudden death. The authors present a case of a 26 year old young male, carpenter by occupation, previously healthy, with sudden death. The internal and external postmortem findings were normal except for mild right ventricular hypertrophy. But histo-pathological examination of heart tissues revealed replacement of myocardial tissue with mature fibrofatty tissue. The following medico-legal autopsy case is being reported for its rarity and the importance of histopathology to find out the cause of death.
