Question

Difficulty: HardGynecologic Oncology

Match each patient's clinical presentation with the characteristic histopathological finding expected on biopsy or surgical excision of their adnexal mass.

  • A 62-year-old woman with new-onset vaginal bleeding, a 14-mm endometrial stripe, and an 8-cm solid left ovarian mass.Microfollicular spaces filled with eosinophilic secretions, surrounded by cells with longitudinally grooved nuclei.
  • A 24-year-old woman with a 4-month history of worsening acne, male-pattern baldness, clitoromegaly, and a 5-cm solid unilateral adnexal mass.Eosinophilic, rod-shaped intracytoplasmic inclusions within interstitial cells alongside tubular structures.
  • A 17-year-old girl with acute-onset abdominal pain, a large predominantly solid right adnexal mass, and markedly elevated serum alpha-fetoprotein (AFP).Central capillary tufts surrounded by visceral and parietal cell layers resembling primitive glomeruli.
  • A 16-year-old phenotypic female with primary amenorrhea, absent axillary hair, a 46,XY karyotype, and bilateral solid adnexal masses.Sheets of uniform cells with clear cytoplasm and prominent nucleoli, separated by fibrous septa containing lymphocytes.

Answer

Granulosa cell tumor matches with Call-Exner bodies; Sertoli-Leydig cell tumor matches with Reinke crystals; Yolk sac tumor matches with Schiller-Duval bodies; Dysgerminoma matches with uniform clear cells and lymphocytes.
Each clinical vignette provides specific hormonal, enzymatic, or genetic clues that perfectly align with a unique ovarian tumor subtype and its pathognomonic histologic finding.

Step-by-Step Solution

1
Analyze the postmenopausal bleeding vignette.
Identify the estrogen-secreting tumor causing endometrial hyperplasia as a granulosa cell tumor, which pathologically features Call-Exner bodies.
Estrogen excess in a postmenopausal woman with an ovarian mass is the hallmark of a granulosa cell tumor.
2
Analyze the virilized young woman vignette.
Identify the testosterone-secreting tumor causing rapid virilization as a Sertoli-Leydig cell tumor, characterized by Reinke crystals.
Rapid-onset hyperandrogenism with a solid adnexal mass requires matching with the sex cord-stromal tumor that produces androgens.
3
Analyze the AFP-elevated young girl vignette.
Identify the AFP-secreting mass as a yolk sac tumor, which classically contains Schiller-Duval bodies.
AFP is the specific tumor marker for endodermal sinus (yolk sac) tumors.
4
Analyze the 46,XY phenotypic female vignette.
Identify the tumor arising in dysgenetic gonads as a dysgerminoma, marked by sheets of clear cells with lymphocytic infiltrates.
Patients with a Y chromosome and female phenotype are at high risk for dysgerminomas, requiring prophylactic gonadectomy.

Key Concept

Clinical and histopathological correlation of specialized ovarian neoplasms (sex cord-stromal and germ cell tumors).
