Abstract

Karsinoma sekretori kelenjar liur adalah karsinoma tingkat rendah yang ditandai dengan kemiripan morfologis dengan karsinoma sekretori mammae dan fusi gen ETV6-NTRK3. Kami melaporkan kasus jarang seorang perempuan berusia 53 tahun dengan benjolan pada parotis sejak 6 bulan. Pemeriksaan histopatologi dari spesimen parotidektomi memperlihatkan proliferasi sel tumor membentuk struktur mikrokistik dengan lumen berisi sekret eosinofilik, sitoplasma granular eosinofilik dan bervakuol. Diagnosis banding utama karsinoma sekretorik adalah dengan karsinoma sel asinik derajat rendah. Keduanya dapat dibedakan dengan pemeriksaan histokimia PAS positif pada sekret dan imunohistokimia positif kuat untuk S100 serta negatif untuk DOG1. Identifikasi translokasi t(12;15) (p13;q25) merupakan standar emas untuk diagnosis. Pada sumber daya rendah di mana analisis molekuler tidak tersedia, maka pemeriksaan histopatologi dan menggunakan imunohistokimia merupakan alat kunci untuk menegakkan diagnosis yang tepat.

Abstract

Objective : This article objective is to describe cytology diagnosis difficulties of yolk sac tumors of the ovary.Method : Case reports and literature review.Case : The author reports the case of a 24 year old woman who complained of an enlarged stomach. Serum AFP increased to 16,519.7 U/mL. Ultrasound examination revealed solid and irregular mass of ovarian, so the conclusion was suspect ovarian carcinoma. Conclusion of CT scan examination was a solid ovarian tumor. The working diagnosis was suspect ovarian carcinoma. Optimal debulking was performed, accompanied by taking a sample from the peritoneal rinse fluid. Microscopic examination of peritoneal fluid showed the distribution and group of cells with pleomorphic nuclei, partly hyperchromatic, partly vesicular with coarse chromatin and prominent nucleoli. There were also cells with polygonal nuclei, small nuclei, basophilic and vacuole cytoplasm with a mucoid background. These cells formed a solid arrangement. Conclusion from these features was carcinoma metastases to the peritoneal fluid. Microscopic examination from tumor tissue sample showed an ovarian yolk sac tumor appearance.Conclusion : Cytologic examination of peritoneal fluid in cases of ovarian yolk sac tumor is quite difficult to determine the diagnosis. This is due to the microscopic appearance of tumor cells which often looks like a carcinoma and limited literature about this tumors in the peritoneal fluid.Keywords: Yolk sac tumor, ovary,Â
