Clinical Case Reports, Volume 14, Issue 5, May 2026.ABSTRACT Pagetoid spread (PS) of anorectal cancer is relatively rare and is associated with poor prognosis compared with Extramammary Paget disease. It is therefore essential to accurately differentiate between the two entities. In PS cases, the primary tumor lesion is usually obvious; however, this is not the case in nonmass‐forming type anorectal ...

Advanced Gastric Cancer Presenting as a Giant Subepithelial Lesion: A Case Report
Clinical Case Reports, Volume 14, Issue 5, May 2026.A giant subepithelial lesion. ABSTRACT Gastric cancer may occasionally present with a subepithelial lesion‐like appearance. When a gastric gastrointestinal stromal tumor (GIST) is suspected preoperatively without definitive pathological confirmation, intraoperative frozen section analysis is recommended to prevent inappropriate surgical intervention.

Clinical Case Reports, Volume 14, Issue 5, May 2026.ABSTRACT Ovarian fibroma with minor sex cord elements is a rare and underrecognized histological variant of ovarian stromal tumors. While the bulk of the tumor resembles a classic fibroma, the presence of small foci of sexcord‐like cells can create a diagnostic dilemma, particularly in limited samples.

Clinical Case Reports, Volume 14, Issue 5, May 2026.ABSTRACT Uterine leiomyomas, commonly known as fibroids, are the most prevalent pelvic tumors in females, affecting 20%–30% of women of reproductive age. However, large pedunculated subserosal leiomyomas presenting during early pregnancy are uncommon and may mimic adnexal or intra‐abdominal malignancies, posing diagnostic and management challenges ...
