Brenner tumours are an uncommon subtype of the surface epithelial-stromal tumour group of ovarian neoplasms. The majority are benign, but some can be malignant. [1] They are most frequently found incidentally on pelvic examination or at laparotomy. [2] Brenner tumours very rarely can occur in other locations, including the testes. [3]
Surface epithelial-stromal tumors are labeled in center of the main diagram, and represent all types except the ones separated at top. Epithelial-stromal tumors are classified on the basis of the epithelial cell type, the relative amounts of epithelium and stroma, the presence of papillary processes, and the location of the epithelial elements.
Histologically, these tumors consists of monotonous islands of granulosa cells with "coffee-bean" nuclei. That same nuclear groove appearance noted in Brenner tumour , an epithelial-stromal ovarian tumor distinguishable by nests of transitional epithelial cells (urothelial) with longitudinal nuclear grooves (coffee bean nuclei) in abundant ...
Micrograph of a cystic Walthard cell rest (lower right of image) within the connective tissue of a fallopian tube (tubal epithelium – upper left of image). H&E stain . Walthard cell rests , sometimes called Walthard cell nests , are a benign cluster of epithelial cells most commonly found in the connective tissue of the fallopian tubes , but ...
Carcinosarcoma of the uterus. In gross appearance, MMMTs are fleshier than adenocarcinomas, may be bulky and polypoid, and sometimes protrude through the cervical os.On histology, the tumors consist of adenocarcinoma (endometrioid, serous or clear cell) mixed with the malignant mesenchymal elements; alternatively, the tumor may contain two distinct and separate epithelial and mesenchymal ...
For example, studies show that clear-cell tumor cells proliferate at lower rates than serous adenocarcinomas which then could aid in a lower response from clear-cell tumors to chemotherapies. [ 7 ] Given that treatment options are limited for ovarian clear-cell cancer patients, researchers are studying biomarkers or specific pathways that could ...
In terms of the image obtained, it can be 1-D (i.e. a line), 2-D (a plane), 3-D (a volume), or 0-D (a single value), and it can be a video or a single image. In most cases, the result is displayed to the operator along with a conventional image of the tissue, which shows where in the tissue the different stiffness values occur.
