Abstract

Background: Alveolar soft part sarcoma (ASPS) are slow-growing inert soft tissue masses, but fast-growing masses are also reported. Because the cancer tissue is rich in blood vessels, distant metastasis is easy to occur through the blood tract, and lung metastasis is the most common. The diagnosis of ASPS should be combined with histopathology examination because of its rarity and often misdiagnosed, especially in unusual sites. Case presentation: A 22-year-old female came to the oncology surgery polyclinic at Dr. M. Djamil General Hospital Padang with a chief complaint of a lump in her left thigh since 1 year ago and has been getting enlarged in the last 6 months. The lump has been painful for the last 2 months. Upon an intraoperative frozen section examination, it was concluded that the lesion was malignant. Then, the tissue was prepared from formalin fixed paraffin embedded (FFPE), and the lesion was diagnosed as alveolar soft part sarcoma. Conclusion: In the case of ASPS, surgical management has an important role. The goal of the intraoperative frozen section of this patient is to determine whether the lesion is benign or malignant. There is a need for histological examination, collaboration, and optimal communication between pathologists and surgeons to avoid limitations and pitfalls examination.

Abstract

Background: Meningiomas are common primary brain tumors with variable clinical behavior. While most are benign, a subset exhibits aggressive characteristics and a high recurrence rate. This study aimed to investigate the association of Programmed Death-Ligand 1 (PD-L1) and Ki-67 labeling index with histopathological grade and recurrence in meningioma. Methods: A retrospective study was conducted on 139 cases of meningioma diagnosed between January 2020 and December 2023. PD-L1 expression was evaluated using immunohistochemistry (IHC) and scored using the combined positive score (CPS). Ki-67 labeling index was determined as the percentage of tumor cells with positive nuclear staining. The association of PD-L1 and Ki-67 with histopathological grade and recurrence was analyzed. Results: PD-L1 expression was positive in 66.7% of cases and was significantly associated with recurrence (p = 0.006). A higher Ki-67 labeling index (>4%) was observed in 68.9% of cases and was also significantly associated with recurrence (p = 0.013). No significant association was found between PD-L1 expression or Ki-67 labeling index and histopathological grade. Conclusion: PD-L1 expression and Ki-67 labeling index may serve as potential prognostic markers for predicting recurrence in meningioma. Further studies are needed to validate these findings and explore their potential therapeutic implications.
