Malignancy in struma ovarii is a rare form of ovarian germ cell tumour. Because of its rarity, the diagnosis and management of the tumour have not been clearly defined. We present a case of 67- year-old female with papillary carcinoma arising in struma ovarii and review the literature on malignancy in struma ovarii cases, focusing on management of these cases.

Clear-cell sarcoma (CCS) is a soft-tissue neoplasm that morphologically resembles cutaneous malignant melanoma but has a distinct molecular profile. Gastrointestinal and intra-abdominal CCSs are very rare. Here, the authors present 3 cases of intra-abdominal CCS and review the literature. Of these cases, 2 involved the small bowel, and 1 involved the peritoneum. Cases 1 and 3 had the characteristic CCS morphology, but case 2 was morphologically unusual and therefore difficult to diagnose. It had relatively small cells with less prominence of clear cells; many pseudoglandular structures were also present. It also showed aberrant expression of epithelial membrane antigen (EMA). The other 2 cases also involved some diagnostic uncertainty and were therefore referred to specialized centers. The authors wish to emphasize the importance of molecular studies in making a conclusive diagnosis of intra-abdominal CCS.

Roseoloviruses are ubiquitous worldwide. Its infection in children is very common causing a disease named as Roseola infantum. It appears that most of the children are still being suffered by the same disease without any proper treatment all over the world. And, the situation becomes worst when these latent viruses reactivated in future to develop disease complications and cancer in human. The Present review is an attempt to describe Roseoloviruses causing diseases including cancer in human in the light of recent researches done so far in the past.

Cytomegalovirus is a kind of herpes virus, HHV-5. It primarily causes congenital infections and the fetal abnormalities during pregnancies. Sometimes, very serious complications and consequences may occur. As human cytomegalovirus is a ubiquitous virus occurring worldwide in nature their infections are very common in human. It has got lifelong latency in human with their reactivation causing cancer in future. The present paper deals with the study of causes and consequences of disease complex and the development of cancer by primary infection and the reactivation of HCMV in human.
