Match each patient's clinical presentation, laboratory findings, and histologic description with the most likely corresponding ovarian neoplasm.

  • A 16-year-old girl presents with pelvic pain. Evaluation reveals a solid adnexal mass. Labs show markedly elevated lactate dehydrogenase (LDH). Histopathology reveals sheets of uniform cells with clear cytoplasm and central nuclei.Dysgerminoma
  • A 19-year-old woman presents with rapid abdominal enlargement. Evaluation shows a large solid ovarian mass and significantly elevated alpha-fetoprotein (AFP). Biopsy reveals Schiller-Duval bodies.Yolk sac tumor
  • A 64-year-old woman presents with postmenopausal bleeding. Ultrasound shows a thickened endometrial stripe and a unilateral complex ovarian mass. Labs show elevated inhibin levels. Biopsy reveals Call-Exner bodies.Granulosa cell tumor
  • A 26-year-old woman presents with deepening of her voice, male-pattern hair growth, and clitoromegaly. She has a solid ovarian mass. Labs show elevated testosterone. Histopathology reveals Reinke crystals.Sertoli-Leydig cell tumor
  • A 32-year-old woman presents with palpitations, weight loss, and heat intolerance. TSH is suppressed, and free T4 is elevated. Radioiodine scan shows uptake localized to the pelvis in a complex adnexal mass.Struma ovarii

Cevap

The correct matches are: 16-year-old with elevated LDH matches Dysgerminoma; 19-year-old with elevated AFP matches Yolk sac tumor; 64-year-old with elevated inhibin matches Granulosa cell tumor; 26-year-old with virilization matches Sertoli-Leydig cell tumor; 32-year-old with hyperthyroidism matches Struma ovarii.
Each clinical presentation contains classic pathognomonic features of specific ovarian neoplasms. Dysgerminoma uniquely correlates with elevated LDH and 'fried egg' uniform cells. Yolk sac tumor strictly correlates with elevated AFP and Schiller-Duval bodies. Granulosa cell tumor correlates with elevated inhibin, estrogen excess (causing postmenopausal bleeding), and Call-Exner bodies. Sertoli-Leydig cell tumor correlates with testosterone excess (causing virilization) and Reinke crystals. Struma ovarii correlates with hyperthyroidism due to ectopic thyroid tissue in the pelvis.

Adım Adım Çözüm

1
Analyze each clinical vignette for patient age, symptoms, and specific tumor markers.
Identify unique markers such as LDH, AFP, inhibin, testosterone, and thyroxine in each respective patient.
Ovarian neoplasms have highly specific biochemical profiles that dictate their clinical manifestations.
2
Correlate the histopathological findings with known ovarian tumor subtypes.
Match Schiller-Duval bodies, Call-Exner bodies, Reinke crystals, and uniform 'fried egg' cells to their corresponding tumors.
Histopathology provides the definitive diagnosis for classifying complex ovarian masses.
3
Synthesize the clinical, laboratory, and pathological data to confirm the final pairings.
All five distinct clinical profiles are successfully matched to the five major specialized ovarian neoplasms.
Combining multiple diagnostic modalities ensures accuracy in identifying these varied tumors.
