Musinous cystic neoplasia mimicking hydatid cyst in the liver: Two rare cases.

Mucinous cystic neoplasm of the liver (MCN-L) is a rare tumor which accounts for less than 5% of all liver cysts. Although they are considered to be "benign cysts" radiologically and clinically because of their slow growth, they are considered as premalignant. We present two radiologically misdiagnosed cases that operated in a short time range, in order to increase awareness for these rare tumors.

The 1000 Mitoses Project: A Consensus-Based International Collaborative Study on Mitotic Figures Classification.

The identification of mitotic figures is essential for the diagnosis, grading, and classification of various different tumors. Despite its importance, there is a paucity of literature reporting the consistency in interpreting mitotic figures among pathologists. This study leverages publicly accessible datasets and social media to recruit an international group of pathologists to score an image database of more than 1000 mitotic figures collectively.

Tumor Budding Should Be in Oral Cavity Cancer Reporting: A Retrospective Cohort Study Based on Tumor Microenvironment.

The utility of histological grading, which is useful in predicting prognosis in many tumors, is controversial for oral squamous cell carcinoma (OSCC). Therefore, new histopathological parameters should be added to histopathology reports of OSCCs. The study aimed to evaluate the parameters of worst invasion pattern (WPOI) and tumor budding in patients with OSCC, to compare them with other histopathological parameters, clinical data and overall survival, and to evaluate these results within the literature.
