The first diagnosis was molar pregnancy due to previous ultrasoni...
giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...

 Materials and Methods: The study was carried out from January 2017 to 2020 Department Pathology Tertiary care hospital. biopsy specimens spastic segment colostomy or ileostomy sites were sent for evalu...
spermatogonial stem cell (ssc) technologies provide multiple opportunities for research in the field of biotechnology and regenerative medicine. the therapeutic use of embryonic stem cells (escs) is restricted due to severe ethical and immunological concerns. therefore, we need a new pluripotent cell type. despite well-known role of germ cells in the gametogenesis, some facts apparently show th...
Dysgerminomas are the most common of primitive germ cell tumors of the ovary, accounting for 1-5% of all ovarian malignancies. The reproductive age group females are most commonly affected, thereby causing problems in conception and if pregnancy occurs, it leads to feto-maternal compromise. It is extremely rare to have a successful natural pregnancy, with viable child birth with a coexisting dy...
Germ cell tumors are rare neoplasms that affect young males. Nearly 99% of patients with localized stage I disease and nearly 80% of patients with metastatic disease can be cured. Even patients who relapse following chemotherapy can achieve a long-term survival in approximately 30-40% of cases. The main objective in early stages and in good prognosis patients has changed in recent years, and it...
PURPOSE Recent epidemiological studies have demonstrated an increasing incidence of testicular cancer in white men which appears to be correlated with the period of birth. Because this birth cohort phenomenon can explain etiological factors in testicular cancer, we determine whether this trend is present throughout the United States based on an analysis of testicular cancer incidence by birth c...
