PD-L1 protein expression by Combined Positive Score (CPS) in patients with muscle invasive or advanced urothelial carcinoma: a single institution experience.

Introduction: Immune checkpoint inhibitors have revolutionized the treatment of patients with advanced urothelial carcinoma (UC) in the frontline and relapsed settings. Lebanon has one of the highest incidence of UC worldwide, yet no data exists regarding the expression of PD-L1 by Combined Positive Score (CPS) in advanced disease.

Methods: We reviewed all patients treated at our institution for high grade UC, stage pT2 and above, between January 2017 and March 2021.

A case of pelvic actinomycosis affecting genital, urinary and digestive tracts: a rare misleading diagnosis.

Pelvic actinomycosis is an uncommon chronic invasive disease caused by a bacteria of the Its diagnosis constitutes a clinical challenge and is usually reached in the postoperative period after resecting a pelvic mass that usually mimics advanced ovarian cancer. Although pelvic actinomyocosis involving the digestive and genital tract has been commonly described, very few reports have described cases involving both ovaries and requiring partial cystectomy for bladder involvement. Herein, we illustrate a case of pelvic actinomycosis with extensive involvement of multiple pelvic organs, misleading the surgeon into undergoing a complete clearance of the wrongfully thought adnexal malignancy.

Periductal stromal tumor of the breast in a young lady: A case report.

We present the case of a 30-year-old lady who underwent a core needle biopsy for a BIRADS 4 lesion of her left breast and was diagnosed as having a cellular fibroadenoma. The final diagnosis after excision returned to be a periductal stromal tumor (PST). An extremely rare entity, the PST is actually classified as a subtype of phyllodes tumor, with specific criteria that are only found upon histological examination of the specimen.
