Match each characteristic histological or clinical presentation of a gynecologic neoplasm with its most closely associated serum tumor marker.
- An ovarian neoplasm characterized by sheets of uniform cells with clear cytoplasm and central nuclei, separated by fibrous septa containing a lymphocytic infiltrate.Lactate dehydrogenase (LDH)
- An aggressive germ cell tumor characterized histologically by Schiller-Duval bodies, which are papillary structures resembling primitive glomeruli.Alpha-fetoprotein (AFP)
- A malignant epithelial ovarian tumor frequently presenting with bilateral complex cystic masses; histology demonstrates papillary structures and concentric calcified concretions.Cancer antigen 125 (CA-125)
- A hormonally active ovarian tumor in a postmenopausal woman presenting with vaginal bleeding and endometrial hyperplasia; histology reveals Call-Exner bodies.Inhibin
Cevap
Dysgerminoma matches with LDH, Yolk sac tumor matches with AFP, Serous cystadenocarcinoma matches with CA-125, and Granulosa cell tumor matches with Inhibin.
Each ovarian tumor type has a distinct embryologic origin, histological appearance, and biochemical profile. Recognizing the unique combinations (e.g., Schiller-Duval bodies with AFP, or Call-Exner bodies with Inhibin) is essential for correct classification and subsequent management.
Adım Adım Çözüm
Anahtar Kavram
Diagnosis and monitoring of ovarian neoplasms rely heavily on specific serum tumor markers correlated with histological findings.
