Abstract
Background: Swyer syndrome is a condition of pure gonadal dysgenesis with 46, XY karyotype. These patients have female external phenotype and usually presented with primary amenorrhea. Detailed history, clinical, radiological and hormonal evaluation, karyotyping and histopathology are needed for diagnosis. Due to the presence of Y chromosomes these patients have streak gonads with increased risk of development of gonadoblastoma. Early diagnosis of Swyer syndrome followed by prophylactic gonadectomy is very important.
Case presentation: A 19-year-old female presented with the complaints of primary amenorrhea. The clinical, radiological, hormonal assessment and karyotyping test made the diagnosis of Swyer syndrome. The histopathological examination revealed left sided streak gonad and right sided gonadoblastoma.
Conclusion: Swyer syndrome is a rare form of disorders of sexual development. As there is high chance of gonadal malignancy, these patients should be counseled for preventive bilateral salpingo-oophorectomy

Abstract
Background: Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide and its incidence is rising steadily in developing nations. The patient prognosis for CRC remains poor, despite advances in surgery and treatment. Additionally, there are currently no reliable prognostic approaches for CRC, despite the use of conventional prognostic factors. Immune checkpoints blockades (ICB) have emerged as a promising treatment strategy and have dramatically improved long-term survival in several malignances. The “PD-1 (programmed cell death-1)”/PD-L1 (programmed cell death-ligand 1) axis plays an important role to control immune suppression by down-regulating T effector cell activities enable tumor cells to escape from the host’s anti-tumor immune surveillance. Aim of this study was to evaluate the expression of PD-L1 (28-8 clone) in resected samples of colorectal cancer.
Methods: This was a cross-sectional observational study. A total 64 cases were selected from the patients who were diagnosed as adenocarcinoma from resected samples received in the department of pathology at BSMMU from July 2021 to June 2023. Immuno-histochemical staining for PD-L1 was performed along with appropriate positive control.
Results: In this study PD-L1 immuno-expression was found in 14 (21.9%) out of 64 cases. However, no expression was found in rest of the 50 (78.1%) cases.
Conclusion: Evaluation of expression of PD-L1 may emerge as a new marker and target for the immunotherapy of colorectal cancer.
