    A 30-year-old, nulliparous woman presented with a history of subfertility. On examination she was found to have uterine fibroid of 28 weeks size of gravid uterus and subsequently laporatomy myomectomy was performed. Multilobulated masses, with diameters ranging from 22 mm to 160 mm were found. Cut sections of the lobulated masses showed whitish whorled cut surface. One of the multilobulated masses had a cystic cavity, measuring 60x50x35 mm(3). Light microscopic findings of the mass with the cystic cavity showed a well-circumscribed cellular tumour composed of cells exhibiting moderate nuclear atypia which were enlarged, nuclei with prominent chromatin clumping and were distributed in areas. Some tumour cells showed large nuclear pseudoinclusions, multinucleated or multilobated tumour giant cells, smudging and few enlarged nucleoli. Mitotic activity was 4 MFs per 10 HPFs. Occasional cells with intracytoplasmic inclusions resembling rhabdoid - like features were seen. There were no atypical mitoses or tumour necroses were noted. Diagnosis of atypical leiomyoma or symplastic leiomyoma was made. Atypical or symplastic leiomyomas are rare in the region of Malaysia and the present case discusses its incidence in younger age, its morphological features along with diagnosis and clinical outcome.

    Giant cell myocarditis (GCM) is a rare but fatal disease of idiopathic origin. It results in focal necrosis of myocardium. This is a case report of middle aged Malaysian Indian female who died due to cardiac tamponade due to rupture myocardium and tear in the root of aorta. On naked eye examination, it simply resembled as recent as well as old fibrotic areas of myocardial infarction. She was clinically diagnosed as a case of obstructive cardiomyopathy with atrioventricular block, and was on pace maker. There was subendocardial fibrosis and left ventricular transmural infarction in the left ventricle. On histopathology, this was diagnosed as GCM, there were widespread areas of inflammatory cellular infiltration within the myocardium with multinucleated giant cells and granulomas interspersed with lymphocytes. Microscopic field showed up to 10 multinucleated giant cells. In this case, there were focal areas at multiple locations and caused uneven thickness in the left ventricle wall. Idiopathic GCM is very rare and causation of hemopericardium is the unique feature of this case. In this case the direct link of GCM with aortitis and rupture of left ventricle wall resulting in hemopericardium is shown. This case is documented through macroscopic as well as microscopic photographs in H&E, Ziel-Nelson, and GMS staining.

    A paramyxovirus virus termed Nipah virus has been identified as the etiologic agent of an outbreak of severe encephalitis in people with close contact exposure to pigs in Malaysia and Singapore. The outbreak was first noted in late September 1998 and by mid-June 1999, more than 265 encephalitis cases, including 105 deaths, had been reported in Malaysia, and 11 cases of encephalitis or respiratory illness with one death had been reported in Singapore. Electron microscopic, serologic, and genetic studies indicate that this virus belongs to the family Paramyxoviridae and is most closely related to the recently discovered Hendra virus. We suggest that these two viruses are representative of a new genus within the family Paramyxoviridae. Like Hendra virus, Nipah virus is unusual among the paramyxoviruses in its ability to infect and cause potentially fatal disease in a number of host species, including humans.
