The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
If 5 or more mitotic figures are present in 10 high powered fields but the behavior still appears benign, may append “with significant mitotic activity”. Moderate to severe atypia without tumor cell necrosis atypical leiomyoma if < 10 mitotic figures per high power field or; leiomyosarcoma if ≥ 10 mitotic figures per high power field
It is composed of a collection of abnormal endometrial cells, arising from the glands that line the uterus, which have a tendency over time to progress to the most common form of uterine cancer—endometrial adenocarcinoma, endometrioid type.
Intravascular papillary endothelial hyperplasia typically manifest as deep nodules or well-defined, round, red, or purple superficial papules.They are usually tiny, ranging in size from 0.5 to 5 cm. [3] IPEH lesions are most common in the digits and among blood arteries throughout the body, although they can also form in the head, neck, and body.
Ovarian endometrioid tumors are part of the surface epithelial tumor group of ovarian neoplasms (10–20% of which are the endometrioid type). Benign and borderline variants are rare, as the majority are malignant. There is an association with endometriosis and concurrent primary endometrial carcinoma (endometrial cancer).
A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. [1] The word is from leio- 'smooth' myo- 'muscle' and sarcoma 'tumor of connective tissue'. The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
It is an uncommon form of endometrial cancer that typically arises in postmenopausal women. It is typically diagnosed on endometrial biopsy, prompted by post-menopausal bleeding. Unlike the more common low-grade endometrioid endometrial adenocarcinoma, uterine serous carcinoma does not develop from endometrial hyperplasia and is not hormone ...
Other causes are acquired, such as cervical stenosis, intrauterine adhesions, endometrial cancer, and cervical cancer. [ 3 ] Additionally, hematometra may develop as a complication of uterine or cervical surgery such as endometrial ablation , where scar tissue in the endometrium can "wall off" sections of endometrial glands and stroma causing ...
