Benign tumors of the ovary

Objective: The aim of this study is to analyze the characteristics of pediatric ovarian tumors (OTs) and evaluate treatment strategies for ovary-sparing tumorectomy (OST). Materials and Methods: Medical records of children from October 2011 to December 2021 were reviewed. Data regarding clinical characteristics, pathological type, and management of OST were analyzed. Results: In total, 61 patients with OTs were screened. The median age was 14.8 ± 3.0 years. The median length and volume of borderline and malignant OTs were larger than those of benign OTs ( P  < ...

BACKGROUND: The precision of minimally invasive surgery (MIS) to resect benign ovarian and paratubal masses while preserving adnexa in children is unclear. This study evaluated the integrity of laparoscopy to spare adnexa while resecting benign pathologies in children. METHODS: The institutional pathology database was queried to identify patients aged 18 years and younger having any ovarian or tubal lesion resected at a comprehensive children's hospital between 2006 and 2021...

BACKGROUND: Fibroid is the most prevalent benign tumor of the female genital tract. Intravenous and intracardiac leiomyomatosis (IVL and ICLM, respectively) are rare complications that present with symptoms of pulmonary thromboembolism and heart failure and whose etiology, despite controversial, is a direct vascular invasion by a primary uterine leiomyoma. CASE PRESENTATION: We present the case of a 31-year-old female patient with a previous history of pelvic pain and dysmenorrhea, whose ultrasound showed an enlarged and heterogeneous uterus...

BACKGROUND: Adenomatoid tumors (ATs) are benign tumors originating from the mesothelium. ATs of the ovary are rare, and can easily be confused with malignancy due to the histomorphological diversity. Thus, it is difficult in histopathological and differential diagnosis, especially during intraoperative frozen pathological diagnosis, which directly affects the resection scope of surgery. CASE PRESENTATION: In this study, we reported two patients (58 and 41 year old) with ovarian ATs...

INTRODUCTION: Paraovarian or paratubal cysts both define cysts located between the ovary and the fallopian tube. They are usually benign and frequently occur in the third and fourth decade of life. Paratubal cysts are defined as giant when they exceed the threshold of 150 mm. METHODS: We report the case of a 15-year-old girl who complained about diffuse abdominal pain since 2 years that was diagnosed with a 196 mm × 90 mm × 267 mm giant paratubal cyst...

BACKGROUND: Mature teratomas belong to the group of germ line ovarian tumors; they generally have benign behavior. Malignant transformation occurs in 0.2% to 1% of tumors. The objective is to show the results of peritonectomy with HIPEC in the treatment of a mature teratoma with malignant differentiation with signet ring cells. CLINICAL CASE: 43-year-old woman diagnosed with mature malignant teratoma with signet ring cells. It was performed optimal primary cytoreduction surgery, total hysterectomy, bilateral salpingo-oophorectomy, peritonectomy, appendectomy, cholecystectomy and splenectomy adding intraoperative hyperthermic chemotherapy (HIPEC)...

Meigs syndrome is a rare disorder characterized by a triad of benign ovarian tumor, ascites, and pleural effusion. Despite its benign nature, its presentation can be similar to metastatic malignancy, making preoperative diagnosis often challenging. The differential diagnosis includes serious and even life-threatening conditions. Meigs syndrome is most common in postmenopausal women and is extremely rare in children. It is often undiagnosed until an invasive surgery is performed. The fact that surgery includes a unilateral salpingo-oophorectomy in females of reproductive age raises concerns for future fertility and other risks associated with this intervention...

Ovarian mucinous cystadenomas are benign, but they can rarely recur if incompletely excised. We are the very first to report a case of recurrent mucinous neoplasm originating from an ovarian mucinous cystadenoma after adnexectomy as the first procedure. A 58-year-old woman was referred to our hospital with a two-year history of abdominal fullness. Magnetic resonance imaging (MRI) demonstrated a pelvi-abdominal cyst measuring 37 cm, without solid components within the cyst. A laparotomy revealed a huge cystic tumor originating from the right ovary...

BACKGROUND: Cell block preparation is routine practice in cytopathology these days because of its pivotal role in increasing diagnostic yield and ancillary studies. In the present era of personalized medicine in oncology, ancillary techniques such as immunohistochemistry (IHC) and molecular analysis are gaining more importance. METHODS: A retrospective study was conducted in the Department of Pathology, over 6 months, which included 144 cases of Fine Needle Aspiration Cytology (FNAC) of abdominopelvic masses and 105 cases of ascitic fluids...

PURPOSE: To evaluate whether previous ovarian removal concomitant with benign hysterectomy improves prognosis in a cohort of women with breast cancer. METHODS: In this nationwide register-based cohort study, risk of recurrence and mortality were examined in 4563 women with invasive breast cancer and previous bilateral salpingo-oophorectomy (BSO) concomitant with benign hysterectomy, during 1977-2018. Comparing with benign hysterectomy alone, hazard ratios (HRs) and 95% confidence intervals (CIs) were evaluated by Cox-proportional hazards regression models...

Ovarian cystadenofibroma is a rare benign tumor comprised of both epithelial and stromal components. It is one the unique tumors which is usually mistaken for malignancy on imaging because of partly solid and partly cystic appearance. Frozen section and subsequent histopathological examinations play a vital role in arriving at definite diagnosis and thus avoiding unnecessary extensive surgical procedure. We described a case of bilateral ovarian cystadenofibroma in a 64 years old female with the clinical impression of malignancy and posted for radical surgical procedure...

The Wnt signaling pathway is important in the normal development and regulation of ovarian follicles throughout the lifecycle of females. Dysregulation of the Wnt signaling pathway, genetically or epigenetically, with subsequent activation of β-catenin has been implicated in tumorigenesis of a spectrum of ovarian neoplasms, from benign to malignant. We review the recent findings of the Wnt signaling pathway involved in regulating normal physiologic processes of the ovarian follicle cycle. We also review the β-catenin mutations in a family of low-grade ovarian stromal tumors, focusing on characterizing their shared morphological features and the utility of immunohistochemistry of β-catenin in facilitating the accurate diagnosis of these ovarian stromal tumors...

The Sertoli cell tumor of the ovary is a rare ovarian tumor with non-specific symptoms. According to the literature, endocrine manifestations occur in two-thirds of patients, but testosterone production is extremely rare. Typically, it is a unilateral benign tumor of the ovary that most commonly presents in adolescents and young women of childbearing potential. We report a 29-year-old patient, previously diagnosed to have polycystic ovarian syndrome, who presented with complaints of amenorrhea for the past three years...

Benign mature cystic teratomas are a form of ovarian germ cell tumor that originates from primordial germ cells in the ovaries. Of the three types of teratoma neoplasms, benign mature cystic teratomas (also called dermoid cysts) are the most common. Patients may present with intermittent abdominal or pelvic pain, abdominal enlargement, dysmenorrhea, dyspareunia, or may be asymptomatic. Clinicians should have a high suspicion for benign mature cystic teratomas, which account for more than 20% of all ovarian neoplasms...

Surgical abnormalities of the adnexa in children and adolescents include a variety of ovarian and paraovarian lesions ranging from benign functional cysts to malignant tumors, torsion of the ovary and/or the fallopian tube, and adnexal infectious lesions ranging from salpingitis to tubo-ovarian abscesses. Presentations vary from asymptomatic pelvic masses to acute abdomen, and some ovarian tumors might present with precocious puberty or virilization. Acute pain might be caused by hemorrhage or rupture of ovarian or paraovarian cysts, adnexal torsion or adnexal infection...

The primary ovarian carcinoid tumor is a very rare ovarian tumor, which accounts for approximately 0.5% to 1.7% of all carcinoids and 1% of ovarian cancer. According to its histopathological features, it can be divided into four categories: insular, trabecular, strumal, and mucinous, among which insular carcinoid is common in Western countries. By comparison, the chain-typed and trabecular carcinoid seem to be common in Asian countries. To date, about 150 cases have been reported in the world, and 40% of them are strumal carcinoid tumor of the ovary (SCTO), which is a highly specialized teratoma differentiated from the monomer, and often characterized by the coexistence of thyroid follicular tissue and carcinoid tissue with the neuroendocrine function...

Objectives: Mucinous cystadenomas are among the most common benign adnexal masses. The peak incidence of mucinous cystadenoma appears between the third and fifth decades of life, but rare cases in younger and older women have also been reported. Ovarian cystic formations are usually asymptomatic at early stages, until they grow in size and various compression symptoms appear, such as abdominal discomfort, distention, nausea, vomiting, and increased urination. Case presentation: This is a case of an 86-year-old woman with partial bowel obstruction due to a sizeable adnexal mass...

While synchronous ovarian and endometrial endometrioid carcinomas (ECs) have long been described in the literature, ovarian or endometrial EC involving concomitant endocervical polyp (ECP) has not yet been reported. This study aimed to investigate the histological types and prevalence of gynecological tumors co-existing with ECP and to comprehensively analyze the clinicopathological characteristics of ovarian and endometrial ECs involving ECPs. We searched for ECP cases associated with premalignant lesions or malignancies of the female genital tract occurring between March 2019 and February 2022...

Polypoid endometriosis is a rare form of endometriosis characterized by polypoid masses that histologically often resemble endometrial polyps. We report a case of rapidly progressing polypoid endometriosis that was preoperatively assumed to be advanced ovarian cancer. A 46-year-old woman, para 0, underwent laparoscopic myomectomy and left adnexectomy for uterine fibroids and a left ovarian endometrial cyst after administration of gonadotropin releasing hormone (GnRH) agonist for 4 months. Eleven months postoperatively, rapid right ovarian enlargement occurred...

Introduction: Serous cystadenomas account for approximately 25% of benign ovarian tumors in patients of childbearing age. Their growth is insidious, and the diagnosis can be difficult as they are often asymptomatic, Patients with serous cystadenoma often experience symptoms only if the lesion is twisted or has a mass effect because of its size.This was the case in our patient, whose cough and low back pain prompted her To consult a doctor, which led to the definitive diagnosis and treatment...
