Gynecologic specimens carry more consequence per slide than almost anything else on the surgical bench: a single distinction settles fertility-sparing eligibility, the extent of an operation, a molecular triage, and whether a family is referred for germline testing. This textbook follows the WHO 5th-edition framework from the grossing station through the vulva, cervix, endometrium, myometrium, ovary, fallopian tube, and placenta, building each diagnosis on the biology that now defines it — HPV-dependent versus HPV-independent neoplasia, mismatch-repair loss, TP53 mutation patterns, and the serous carcinogenic sequence in the distal tube. The Diagnostic Discriminator System runs through every chapter: each entity is set against the mimic it is actually confused with, reduced to the finding that separates them, and closed with the line that finding forces into the report.
What This Textbook Puts Under Your Microscope
• Grossing, orientation, and SEE-FIM sampling — sections cut so the feature the diagnosis turns on survives to the slide. • p16, p53, and mismatch-repair pattern reading — wild-type against aberrant, with the null and cytoplasmic traps named. • Cervical glandular neoplasia — HPV-associated against gastric-type adenocarcinoma, with the Silva pattern system applied to nodal risk. • Endometrial hyperplasia through EIN — the thresholds that separate a progestin trial from hysterectomy in a woman who wants to conceive. • The four molecular classes under FIGO 2023 — POLE-mutated, mismatch-repair-deficient, p53-abnormal, and NSMP tumors staged and reported as guidelines now require. • Uterine smooth muscle and stromal tumors — STUMP criteria and the fusion-defined sarcomas that no longer sit under one heading. • Ovarian histotypes and their tubal origin — serous, endometrioid, clear cell, and mucinous tumors separated by morphology and marker profile. • Trophoblastic and placental pathology — p57 interpretation, the trophoblastic tumors, and Amsterdam consensus terminology. Open it before your next gynecologic sign-out — the distinction, the discriminator, and the consequence, in one reference.
