    Diagnosis and Management of Adnexal Masses VANESSA GIVENS, MD; GREGG MITCHELL, MD; CAROLYN HARRAWAY-SMITH, MD; AVINASH REDDY, MD; and DAVID L. MANESS, DO, MSS, University of Tennessee Health Science Center College of Medicine, Memphis, Tennessee Adnexal masses represent a spectrum of conditions from gynecologic and nongynecologic sources. They may be benign or malignant. The initial detection and evaluation of an adnexal mass requires a high index of suspicion, a thorough history and physical examination, and careful attention to subtle historical clues. Timely, appropriate labo- ratory and radiographic studies are required. The most common symptoms reported by women with ovarian cancer are pelvic or abdominal pain; increased abdominal size; bloating; urinary urgency, frequency, or incontinence; early satiety; difficulty eating; and weight loss. These vague symptoms are present for months in up to 93 percent of patients with ovarian cancer. Any of these symptoms occurring daily for more than two weeks, or with failure to respond to appropriate therapy warrant further evaluation. Transvaginal ultrasonography remains the standard for evaluation of adnexal masses. Findings suggestive of malignancy in an adnexal mass include a solid component, thick septations (greater than 2 to 3 mm), bilaterality, Doppler flow to the solid component of the mass, and presence of ascites. Fam- ily physicians can manage many nonmalignant adnexal masses; however, prepubescent girls and postmenopausal women with an adnexal mass should be referred to a gynecologist or gynecologic oncologist for further treatment. All women, regardless of menopausal status, should be referred if they have evidence of metastatic disease, ascites, a complex mass, an adnexal mass greater than 10 cm, or any mass that persists longer than 12 weeks.

  • Pseudocarcinomatous Hyperplasia of the Fallopian Tube Mimicking Tubal
    Lee et al. Journal of Ovarian Research (2016) 9:79 DOI 10.1186/s13048-016-0288-x CASE REPORT Open Access Pseudocarcinomatous hyperplasia of the fallopian tube mimicking tubal cancer: a radiological and pathological diagnostic challenge Nam Kyung Lee1,2†, Kyung Un Choi3†, Ga Jin Han1, Byung Su Kwon4, Yong Jung Song4, Dong Soo Suh4 and Ki Hyung Kim2,4* Abstract Background: Pseudocarcinomatous hyperplasia of the fallopian tube is a rare, benign disease characterized by florid epithelial hyperplasia. Case presentation: The authors present the history and details of a 22-year-old woman with bilateral pelvic masses and a highly elevated serum CA-125 level (1,056 U/ml). Ultrasonography and magnetic resonance imaging (MRI) of the pelvis showed bilateral adnexal complex cystic masses with a fusiform or sausage-like shape. Contrast-enhanced fat-suppressed T1-weighted images showed enhancement of papillary projections of the right adnexal mass and enhancement of an irregular thick wall on the left adnexal mass, suggestive of tubal cancer. Based on MRI and laboratory findings, laparotomy was performed under a putative preoperative diagnosis of tubal cancer. The final pathologic diagnosis was pseudocarcinomatous hyperplasia of tubal epithelium associated with acute and chronic salpingitis in both tubes. Conclusion: The authors report a rare case of pseudocarcinomatous hyperplasia of the fallopian tubes mimicking tubal cancer.

I. Introduction In general, the function of the genital (reproductive) system in males and females is the formation, nurture, and transport of germ cells. In females, an additional function is to provide the proper milieu for the fetal development after conception. Like the urinary system, the genital system derives from intermediate mesoderm. The development of these two systems is tightly interwoven as structures that develop as parts of the urinary system gain function in the genital system. In the adult, the sexual organs differ between males and females. The early genital system, however, is similar in both sexes, and the sexual differentiation of this initially indifferent, bipotential system starts only in the seventh week of embryonic development. The details on how sexual differentiation is determined will be discussed below, but it is worth mentioning here that irregularities in this process result in disorders of sexual differentiation (DSDs). DSDs occur in approximately 1 in 4,500 live births and will be discussed in a separate lecture.

Theca lutein cyst rupture - an unusual cause of acute abdomen : a case report. The Internet Journal of Gynecology and Obstetrics. 2009 Volume 13 Number 1. Abstract A 20 year old illiterate woman who had a spontaneous first trimester abortion followed by instrumental evacuation, presented 4 days later with sudden onset of pain and distension of abdomen along with difficulty in breathing. On examination, she was tachypnoeic, icteric with tachycardia. Abdominal examination revealed guarding and rigidity along with free fluid and vague mass in lower abdomen. Gynaecological examination showed purulent discharge through os with bogginess in all fornices. USG revealed echogenic fluid with bilateral large ovarian masses containing multiple small cysts. Laparotomy was performed with a provisional diagnosis of ruptured theca leutein cysts after 24 hrs of administration of broad spectrum antibiotics. There were bilateral theca leutein cysts of more than 10X15 cm, the left of which has ruptured and the right on the verge of rupture. Bilateral partial cystectomy was performed and histopathological examination confirmed theca lutein cysts with inflammatory infiltrate. INTRODUCTION performed for the same.
