ovarian mucinous cystadenoma

INTRODUCTION: There are limited reports on ovarian neoplasm occurring among identical twins. Most previous reports showed ovarian teratoma found in both twins. Herein, we report for the first time a case of ovarian mucinous cystadenoma with contralateral serous cystadenofibroma found in twin siblings. CASE REPORT: One patient suffered from abdominal distension and the following computed tomography found ovarian mucinous cystadenoma. During the laparoscopy, another ovarian mass was found in the contralateral ovary...

UNLABELLED: The coexistence of a benign Brenner tumour and a mucinous cystadenoma is rare, and their relationship and origin are still enigmatic and challenging. CASE PRESENTATION: In this manuscript, the authors report a case of a 62-year-old nulliparous Syrian woman who presented with severe abdominal distension, which was followed by laparotomy and the excision of a 25×20 cm-cyst; its pathological examination confirmed a benign Brenner's tumour and mucinous cystadenoma...

Epidermoid cyst is a rare benign neoplasm of the ovary, lined by stratified squamous epithelium, lacking skin, adnexal structures, and other teratomatous elements. On the other hand, mucinous cystadenoma is one of the most common benign ovarian neoplasm that microscopically shows cystic areas lined by tall columnar mucinous epithelium. Although its coexistence with other tumours, such as mature cystic teratoma, squamous cell carcinoma, clear cell adenocarcinoma, Brenner's tumour, serous cystadenoma, etc., have been reported, a combination of benign epidermoid cyst and mucinous cystadenoma has rarely been documented in literature...

Tumor heterogeneity remains an ongoing challenge in the field of cancer therapy. Intratumor heterogeneity significantly complicates the diagnosis of cancer and presents challenging clinical problems due to resistance to drug therapy. This study aimed to elucidate the genetic changes histologically (mucinous cystadenoma (MCA), mucinous borderline tumor (MBT), and mucinous ovarian carcinoma (MOC)) in a portion of mucinous ovarian tumors within the same sample. Seven tumor samples obtained from different patients were used to evaluate the genetic mutations in each component...

Mature cystic teratoma is the most common type of ovarian germ cell tumor. Malignant transformation is a rare complication in 1-3% of cases, especially in post-menopausal women. The most common type of malignant transformation by histology is squamous cell carcinoma, followed by adenocarcinoma, carcinoid tumor, melanoma, and sarcoma. Diagnostic difficulties exist due to non-specific findings. No clinical, radiological, or biological signs are specific to malignant transformation. Most patients are diagnosed in advanced stages and have poorer outcomes...

Primary mucinous ovarian neoplasms, gastrointestinal-type (GI-type), are composed of mucin-producing tumor cells resembling intestinal goblet cells or gastric foveolar epithelium. In contrast to seromucinous tumors, which exhibit endocervical-type mucinous differentiation and are thought to be derived from endometriosis, the cell/tissue-of-origin of most GI-type mucinous ovarian tumors is unknown. We identified 8 GI-type mucinous ovarian tumors (cystadenomas, n=4; borderline tumor/carcinoma, n=4) with spatially distinct areas that showed morphologic features of Mullerian-type epithelial differentiation (ciliated cells or endometrioid-type glands)...

A case of a 53-year-old postmenopausal woman presenting a giant ovarian cystic mucinous tumor weighing 24 kg is reported here. When she was seen first at our outpatient clinic, she had gross abdominal distension since 2 years, and she complained of unbearable aggressive pain. Her computed tomography (CT) scan was done which came suggestive of ovarian serous cystadenoma of large massive size 35 x 40 x 32 cm with moderate ascites. On exploratory laparotomy, a giant, totally cystic, vascularized and smooth mass attached to the right ovary was encountered...

BACKGROUND: Giant malignant tumors have an increased risk of intraoperative rupture, which might lead to a worse disease condition and tumor recurrence. We performed a clinical study on patients with a giant ovarian mass who underwent laparoscopy combined with an Aron Alpha method. METHODS: This retrospective clinical study spanned from January 2016 to September 2022 and included 23 patients with giant ovarian tumors treated with an Aron Alpha method. RESULTS: The mean age of the subjects was 47...

Mucinous cystic neoplasms (MCNs) are rare tumors of the liver, occasionally seen in the biliary tree. Epidemiologic data are limited by their indolence and recent changes to diagnostic criteria. They are considered premalignant lesions capable of invasive behavior. While their etiology remains unknown, their female predominance, age of onset, and hormonally responsive ovarian-type stroma suggest ectopic organogenesis during embryologic development. MCNs can typically be recognized on imaging; yet, invasiveness is often indeterminate, and percutaneous tissue biopsy has shown limited value...

Cystic mesothelioma, also known as benign multicystic peritoneal mesothelioma (BMPM), is a rare neoplasm and one of the five main histological types of peritoneal mesothelioma. Although it is usually considered benign histologically, it is increasingly accepted as a 'borderline malignancy' because the local recurrence rate is high. It is more common in middle-aged women and is generally asymptomatic. Considering that BMPM is often found in the pelvis, it is difficult to differentiate from other pelvic and abdominal lesions, such as cystic ovarian masses, especially mucinous cystadenoma-adenocarcinoma, pseudomyxoma peritonei, etc...

BACKGROUND: Mucinous cystadenoma of the ovary is a common gynecologic tumor that usually has a very favorable prognosis. However, if it is not early detected and removed, it can grow to a large size and may cause serious health complications. CASE: A 65-year-old woman was transported to the hospital by the emergency medical service due to overall weakness, markedly enlarged abdomen reminiscent of ascites, breathing difficulties, and swollen legs with eczematous ulcers...

Brenner tumors (BTs) are surface-epithelial stromal cell tumors that are categorized by the World Health Organization as benign, borderline, and malignant. Due to the rarity of BTs, the published literature on these tumors is comprised primarily of case reports and small retrospective studies. We performed a pathology database review spanning the last ten years at our institution revealing nine reported benign BTs. We collected the clinical and pathological data of patients associated with those BTs, describing the clinical presentation and imaging results, and assessing the possible risk factors associated with them...

Primary ovarian mucinous tumors represent a heterogeneous group of neoplasms, and their diagnosis may be challenging. We analyzed 124 primary ovarian mucinous tumors originally diagnosed as mucinous borderline tumors (MBTs) or mucinous carcinomas (MCs), with an emphasis on interobserver diagnostic agreement and the potential for diagnostic support by molecular profiling using a next-generation sequencing targeted panel of 727 DNA and 147 RNA genes. Fourteen experienced pathologists independently assigned a diagnosis from preset options, based on a review of a single digitized slide from each tumor...

UNLABELLED: Ovarian cyst is a fluid-filled sac in the ovary, common among reproductive women. Mucinous cystadenoma is a common variety of non-functional benign lesions that presents vague symptoms and can mislead the diagnosis. A 26-year-old female presented to the clinic with weakness and lethargy, which lasted for 3 months, along with other symptoms like headache, abdominal pain, bloating, nausea, and constipation. She was managed with iron deficiency anaemia, however, her symptoms did not improve...

Ciliated cell markers expressed in epithelial ovarian cancers (EOC) are associated with improved survival. We examined the distribution of cells expressing ciliated cell markers in various EOC histologies and stages. Immunohistochemistry and/or multiplex immunofluorescence were used to determine the expression of FOXJ1 and/or CAPS (ciliated cell markers) in tissue microarrays including 4 normal fallopian tubes, 6 normal endometria, 16 cystadenomas, 25 borderline tumors, 21 low-grade carcinomas, and 118 high-grade carcinomas (HGSOC) (46 serous, 29 endometrioid, 30 clear cell, 13 mucinous)...

Microcystic stromal tumor (MST) is a rare type of pure stromal tumor in the category of ovarian sex cord-stromal tumors. It is characterized by a distinctive microcystic appearance with bland tumor cells. Although the pathological diagnosis can be straightforward based on the typical histomorphology in most MSTs, the cases with morphologic variation can pose a diagnostic challenge due to unfamiliarity of pathologists with the histologic spectrum of MST and its negativity for inhibin and calretinin, the commonly used sex cord-stromal markers...

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...

STUDY OBJECTIVE: To examine the recurrence rates of pediatric benign ovarian neoplasms. METHODS: A retrospective review of females up to 21 years of age who underwent surgery for a benign ovarian neoplasm at eight pediatric hospitals from January 2010 through December 2016 was conducted. Data includes primary operation details, follow-up imaging, and reoperation details. RESULTS: 426 females were included in our cohort, with a median age of 15 years at the time of the primary operation...

PURPOSE: In Afghanistan, research work is still in its infancy and there is no national level tumor registry at the moment in the country that could elaborate the histopathological features of ovarian tumors in the country. The current study was conducted with the aim to describe pathological characteristics of ovarian tumors diagnosed at tertiary level in Afghanistan. PATIENTS AND METHODS: A descriptive cross-sectional study was conducted, including 198 cases diagnosed with ovarian tumors, that were consecutively included in the study from July 2017 to August 2020...
