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
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.
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 ...
[3] Serous cystadenomas (of the ovary) are not related to serous cystadenomas of the pancreas, i.e. the presence of an ovarian or pancreatic one does not suggest an increased risk for the other one. Diagnostic Procedures includes initially ultrasound or colour doppler study to know about size and nature of mass and sometimes CECT.
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]
Hematometra is usually treated by surgical cervical dilation to drain the blood from the uterus. [3] Other treatments target the underlying cause of the hematometra; for example, a hysteroscopy may be required to resect adhesions that have developed following a previous surgery. [ 1 ]
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 ...
