It is unique or paucilocular. It can be associated with other types of benign liver tumors. Characteristic 2D ultrasound appearance is that of a very well defined lesion, with sizes of 2–3 cm or less, showing increased echogenity and, when located in contact with the diaphragm, a "mirror image" phenomenon can be seen.
Adnexal mass; Abdominal CT shows a 7.1 × 4.3 × 5.4 cm septal cystic, solid mass was detected on the left adnexal, and the solid components were enhanced. Specialty: Gynaecology: Symptoms: Pain of the pelvic / illiac regions especially if it involves the ovaries or fallopian tubes: Types: Benign or malignant; simple or complex
Hidradenoma refers to a benign adnexal tumor of the apical sweat gland. [1] [2] These are 1–3 cm translucent blue cystic nodules. It usually presents as a single, small skin-colored lesion, and may be considered closely related to or a variant of poromas. [3] Hidradenomas are often sub-classified based on subtle histologic differences, for ...
Cystadenocarcinoma is a malignant form of a cystadenoma and is a cancer derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur.
High-grade serous carcinoma (HGSC) is a type of tumour that arises from the serous epithelial layer in the abdominopelvic cavity and is mainly found in the ovary.HGSCs make up the majority of ovarian cancer cases [1] and have the lowest survival rates. [2]
It mainly presents in the genital tract, in regions such as the testis [1] and epididymis. [2] Because of this, researchers had a difficult time concluding that type of tumor has a mesothelial origin. Immunohistochemistry staining of tumor samples show that it is indeed positive for mesothelial-markers (calretinin, WT1, and CK6). [3]
Pancreatic mucinous cystadenoma or mucinous cystadenoma of the pancreas (MCN) are a type of mucinous cystic neoplasm of the pancreas. [3] The cure rate is very high in cases on benign cystic lesions, but the case changes if malignant changes ensue. [4] Benign cystadenomas are the most common cystic tumors of the pancreas accounting for 75% of ...
Spiradenomas (SA) are rare, benign cutaneous adnexal tumors that may progress to become their malignant counterparts, i.e. spiradenocarcinomas (SAC). Cutaneous adnexal tumors are a group of skin tumors consisting of tissues that have differentiated (i.e. matured from stem cells) towards one of the four primary adnexal structures found in normal skin: hair follicles, sebaceous sweat glands ...
