Ovary – Changes to WHO Classification (6th edition, 2026) Serous borderline ovarian tumors: The terms “microinvasion” and “microinvasive” are no longer recommended What was previously called microinvasion (single cells and clusters of cells with eosinophilic cytoplasm and low-grade nuclear features) has no clinical significance (see pic 2). It can be mentioned in a comment if desired; Dr. Gilks previously reported it but no longer does What was previously called microinvasive carcinoma represents small foci of low-grade serous carcinoma (see pic 3). Report the size and extent of these foci and diagnose them as a small focus of low-grade serous carcinoma arising in a serous borderline tumor Dr. Gilks.

Mitotic activity in phylllodes tumours is important for grading, but there are various methodologies for determining the mitotic count. This manuscript suggests an approach that could form the basis for standardisation. #breastpathology doi.org/10.1111/his.70293
Mitoses counting in phyllodes tumours: rationale for a standardized hotspot‐based approach

Mitoses counting in phyllodes tumours: rationale for a standardized hotspot‐based approach

Background Breast phyllodes tumours (PTs) are rare biphasic fibroepithelial neoplasms, classified into benign, borderline and malignant categories. Stromal mitotic activity is a key criterion in...

Prostate - Active surveillance may be considered for Gleason score 3+3=6 (GG1) or Gleason score 3+4 (GG2) without cribriform/intraductal carcinoma Definitive treatment is best practice by some modality (radical prostatectomy, radiotherapy, etc) for Gleason score ≥4+3=7 (GG3) or Gleason 3+4=7(GG3) with large cribriform/IDC Dr. McKenney.

Updates from the WHO Classification of Breast Tumors, 6th Edition (not published yet) The WHO 5th edition recommended that encapsulated papillary carcinoma (EPC) with high nuclear grade, increased mitotic activity, and/or a triple-negative or HER2-positive phenotype be graded, staged, and managed as invasive disease In the 6th edition, the WHO now recognizes the existence of rare forms of EPC with high-grade features or ER negativity that may still be categorized as EPC Such tumors may be encountered on core biopsy; classifying them as invasive could lead to inadvertent neoadjuvant therapy The vast majority of EPCs should be low- to intermediate-nuclear grade and ER-positive Dr. Tan #USCAP #pathology #PathX #PathTwitter
