What is Cystadenofibroma?
Ovarian cystadenofibroma is a relatively rare benign ovarian tumor that contains both epithelial and fibrous stromal components. The appearance of cystadenofibroma on imaging is often complex; cystic- to solid-appearing masses may be visualized and it often resembles a malignant tumor.
What is a Cystadenocarcinoma?
Definition. Cystadenocarcinoma is a rare malignant tumor characterized by prominent cystic and, frequently, papillary growth, but it lacks features that characterize cystic variants of other more common salivary gland carcinomas. Cystadenocarcinoma is the malignant counterpart of cystadenoma.
What is mucinous Cystadenofibroma?
A mucinous cystadenofibroma is a non-cancerous type of ovarian tumour. While these tumours are non-cancerous, they can grow to be very large in size and can cause significant symptoms for many patients.
Is a cystadenoma benign or malignant?
Ovarian cystadenomas are common benign epithelial neoplasms which carry an excellent prognosis. The two most frequent types of cystadenomas are serous and mucinous cystadenomas whereas endometrioid and clear cell cystadenomas are rare.
What is ovarian Fibrothecoma?
Ovarian fibrothecoma is a rare, benign, sex cord-stromal neoplasm, with a typically unilateral location in the ovary, characterized by mixed features of both fibroma and thecoma. Patients may be asymptomatic or may present with pelvic/abdominal pain and/or distension and, occasionally, with post-menopausal bleeding.
What causes Endosalpingiosis?
Endosalpingiosis and endometriosis are related benign conditions caused by ectopic epithelium of tubal-like or endometrial differentiation. They affect women mostly during reproductive age and a have a high prevalence of 5-10% [2].
What is mucinous Cystadenocarcinoma?
Mucinous cystadenocarcinoma is a type of tumor in the cystadenocarcinoma grouping. It can occur in the breast as well as in the ovary. Tumors are normally multilocular with various smooth, thin walled cysts. Within the cysts is found a haemorrhagic or cellular debris.
What is Seromucinous cystadenoma?
Seromucinous Cystadenoma/Adenofibroma. These benign tumors account for about 1% of ovarian benign epithelial neoplasms [5]. They are usually cystic but can be adenofibromatous (Figure 1). Cystic lesions are unilocular or oligolocular with smooth outer and inner surfaces. The cyst fluid can be serous or mucinous.
What causes cystadenoma?
Cystadenomas. These develop on the surface of an ovary and might be filled with a watery or a mucous material. Endometriomas. These develop as a result of a condition in which uterine endometrial cells grow outside your uterus (endometriosis).
What causes Fibrothecoma?
Fibromas/fibrothecomas most commonly present due to mass effect causing compression on different organs. In some cases, ovarian fibromas can be part of Meigs’ syndrome, a triad of ovarian fibroma, ascites, and pleural effusion.
What is ovarian cystadenofibroma?
An ovarian cystadenofibroma (CAF) is a relatively uncommon benign epithelial ovarian tumor where the fibrous stroma remains a dominant component of the neoplasm.
What is the pathophysiology of cystadenomas?
Cystadenomas and cystadenofibromas are benign proliferative cysts lined by a bland layer of epithelium that is usually cuboidal or columnar. Most are unicystic, but multicystic cystadenomas may occur.
What are the different types of cystadenofibroma?
Although generally classified as an epithelial tumour, a cystadenofibroma contains both epithelial and stromal components. Recognised histological sub types include 3,5. serous cystadenofibroma of the ovary. mucinous cystadenofibroma of the ovary. endometrioid cystadenofibroma of the ovary. clear cell cystadenofibroma of the ovary.
What is the difference between adenofibromas and cystadenomas?
Cystadenofibromas have a more prominent stromal component than cystadenomas and tend to form more prominent blunt papillae that can extend into the lumen of the cyst or outward from its wall. Simple adenofibromas are benign, but borderline forms also occur.
