Coexisting ovarian serous cystadenoma with fibroma: A very unusual combination.

Surface epithelial neoplasms are the most common ovarian tumors, constituting around 60% of all ovarian malignancies. They are classified as benign, borderline, and malignant. Ovarian cystadenomas are common benign epithelial neoplasms which carry an excellent prognosis. Ovarian thecoma-fibroma groups are uncommon sex cord-stromal neoplasms, constituting 1.0%-4.0% of all ovarian tumors. Most of them are benign and often found in postmenopausal patients. Combination tumors in the ovary are known. The most common combination is mucinous cystadenoma which occurs in association with Brenner tumor, mature cystic teratoma, Sertoli-Leydig cell tumor, or even a serous cystadenoma. A combination of surface epithelial and thecoma-fibroma group is very rarely encountered. A case of one such combination of serous cystadenoma and fibroma of the ovary is being presented here in a postmenopausal woman.

Factors Associated with Torsion in Pediatric Patients with Ovarian Masses.

BACKGROUND: Management of ovarian torsion has evolved toward ovarian preservation regardless of ovarian appearance during surgery. However, patients with torsion and an ovarian neoplasm undergo a disproportionately high rate of oophorectomy. Our objectives were to identify factors associated with ovarian torsion among females with an ovarian mass and to determine if torsion is associated with malignancy. METHODS: A retrospective review of females aged 2-21 y who underwent an operation for an ovarian cyst or neoplasm between 2010 and 2016 at 10 children's hospitals was performed. Multivariate logistic regression was used to assess factors associated with torsion. Imaging data were assessed for sensitivity, specificity, and predictive value in identifying ovarian torsion. RESULTS: Of 814 girls with an ovarian neoplasm, 180 (22%) had torsion. In risk-adjusted analyses, patients with a younger age, mass size >5 cm, abdominal pain, and vomiting had an increased likelihood of torsion (P < 0.01 for all). Patients with a mass >5 cm had two times the odds of torsion (odds ratio: 2.1; confidence interval: 1.2, 3.6). Imaging was not reliable at identifying torsion (sensitivity 34%, positive predictive value 49%) or excluding torsion (specificity 72%, negative predictive value 87%). The rates of malignancy were lower in those with an ovarian mass and torsion than those without torsion (10% versus 17%, P = 0.01). Among the 180 girls with torsion and a mass, 48% underwent oophorectomy of which 14% (n = 12) had a malignancy. CONCLUSIONS: In females with an ovarian neoplasm, torsion is not associated with an increased risk of malignancy and ovarian preservation should be considered.

Benign parotid mass and facial palsy: systematic review.

INTRODUCTION: Parotid masses causing facial palsy are highly indicative of malignancy. A significant number of cases describing benign parotid disease causing facial palsy have been reported. MATERIALS AND METHODS: We performed a systematic review of the literature to establish the aetiology, clinical features, investigations and management undertaken during these presentations to assess how these factors differed from malignant presentations and to establish an evidence-based algorithm for their management. RESULTS: A total of 85 cases were identified from 78 articles. Cystadenolymphomas were the most common histopathological type (p = 0.034). Mean facial palsy recovery duration in neoplastic aetiology was longer than for infective aetiology (p = 0.033). A significant association existed between uncommon infective organisms and development of facial palsy (p = <0.0001). CONCLUSION: Uncommon benign aetiologies are associated with facial palsy. Investigations and management should be guided by patients' clinical presentations, avoiding excessive treatment. Complete facial palsy recovery rates are high, although not immediate.

Identification of Juvenile Cystic Adenomyoma Using High-Resolution Imaging.

BACKGROUND: Juvenile cystic adenomyoma is a rare condition that is often misdiagnosed as a noncommunicating uterine horn or adnexal mass during adolescence. CASES: We describe two patients who presented with dysmenorrhea unresponsive to standard management with oral contraceptives. Both patients were initially misdiagnosed as having endometriotic cysts. Juvenile cystic adenomyoma was suspected on standard pelvic ultrasound scan and subsequent high-resolution three-dimensional ultrasonography. The diagnosis was subsequently confirmed and the lesions successfully treated laparoscopically. CONCLUSION: Gynecologists should be aware of the possibility of juvenile cystic adenomyoma in adolescents with dysmenorrhea refractory to medical management. Three-dimensional ultrasonography may provide the resolution necessary to distinguish this rare condition.

Mucocele of the appendix presenting as an exacerbated chronic tubo-ovarian abscess: A case report and comprehensive review of the literature.

RATIONALE: Appendiceal mucocele is a rare entity of mucinous cystic dilatation of the appendix. It has no typical clinical presentation and is considered a potentially premalignant condition. PATIENT CONCERNS: We present a case of accidental intraoperative finding of an appendiceal mucocele in a 54-year old woman that clinically presented with an exacerbated chronic tubo-ovarian abscess. DIAGNOSES: Trans-vaginal ultrasonography showed an encapsulated, oval, unilocular mass above the uterus with a heteroechogenic structure, homogeneous fluid content, and smooth regular walls without inner proliferation. The histopathologic diagnosis was consistent with an appendiceal cystadenoma. INTERVENTIONS: The patient underwent a simple appendectomy. OUTCOMES: There were no clinical, biochemical or imaging signs of the disease recurrence at 6 months follow up. LESSONS: To our knowledge, this is the only well-documented case of appendiceal mucocele mimicking exacerbated chronic tubo-ovarian abscess reported in the literature. Awareness of a rare entity such as an appendiceal mucocele, which is frequently misdiagnosed as a potential cause of acute abdomen, is necessary for the appropriate management strategy in order to prevent complications.

Intrahepatic biliary cystadenoma with ciliary metaplasia: Report of a rare morphological variant.

Histological diagnosis of biliary cystadenoma is based on the type of epithelial cells lining the cyst and radiological features. The cyst-lining cells are not usually ciliated. We herein report a very rare example of an intrahepatic biliary cystadenoma with ciliated epithelial lining, which had taken us away from this diagnosis toward an intrahepatic foregut duplication cyst. Radiologically, also the lesion was deceptive, and a possibility of hydatid cyst was considered. However, immunohistochemical workup finally led us to this diagnosis. This report would document this rare morphological variant, which may pose diagnostic difficulty.

Diverticulitis of the appendix as debut of appendicular cystadenoma and carcinoid tumor.

Appendiceal diverticulosis is a rare condition with a frequency of 0.004% to 2.1%, and is sometimes an occasional finding during anatomopathologic study of the surgical specimen. It may be presented acutely as a right lower quadrant pain, similar to acute appendicitis for which differential diagnosis must be carried out, and it is associated with appendicular tumors. We report a case of diverticulitis of the appendix as debut of appendicular cystadenoma and carcinoid tumor with representative iconography, being unusual the association of both diseases and even more its preoperative diagnosis.

[Adolescent with paraovarian cyst. Surgycal treatment]. / Adolescente con quiste paraovárico. Tratamiento quirúrgico.

BACKGROUND: Adnexal paraovarian cysts are not frequently seen during teen development, their incidence is around 10% and usually benign. CLINICAL CASE: Adolescent female 15 years old with no pathological family and personal history relevant to her current condition. Chief complaint: Six months ago she complained with abdominal pain in meso, hypogastrium and right iliac fossa. Later, she observed an increased volume on her lower quadrant of the abdomen, mostly on her right side. During physical examination an abdominal tumor was palpated. By an abdominal-rectal manouvre, the presence of tumor was confirmed and located in front of the rectum and no implants. Imaging studies confirmed a paraovarian cyst. She underwent on surgical laparatomy and a paraovarian cyst was found. The histological diagnosis was a cystadenoma. The postoperative course was satisfactory. DISCUSSION: Epidemiological data and ultrasonographic findings are examined to confirm the diagnosis of paraovarian cyst. The laparoscopic treatment for adnexal problems is described.

Treatment and ovarian preservation in children with ovarian tumors.

BACKGROUND/PURPOSE: Ovarian preservation is desirable in children with ovarian tumors. However, the diagnostic and treatment strategies are heterogeneous. The aim of this study was to investigate the management and preservation of ovarian tissue in order to identify the factors associated with ovarian preservation. METHODS: Thirty-seven patients (41 ovaries) were surgically treated for ovarian tumors. Four cases were bilateral. The data on the patient symptoms at presentation, imaging, treatment, outcome, pathology, and status of ovarian preservation were retrospectively analyzed for each patient. RESULTS: Histological examinations revealed 25 mature teratomas, 5 immature teratomas, 5 cystadenomas, 2 dysgerminomas, and other tumors. Ovarian torsion occurred in 16 ovaries (39%). Ovary-sparing surgery was performed in 22 ovaries (53.7%). Successful ovarian preservation was significantly associated with a smaller tumor size, benign pathology, and a lower degree of torsion (P<0.01). CONCLUSIONS: Because the prognosis was favorable in most cases, the preservation of fertility and gonadal function should be a goal in the surgical treatment of ovarian tumors. We recommend ovary-sparing surgery as the first-line treatment for all pediatric ovarian tumors other than those that are preoperatively diagnosed as being malignant and those in which emergent surgical intervention is indicated owing to the suspicion of ovarian torsion.
