Features of benign lesion are: hyperechoic, having coarse, dysmorphic or curvilinear calcifications, comet tail artifact (reflection of a highly calcified object), absence of blood flow in the nodule, and presence of cystic (fluid-filled) nodule. However, the presence of solitary or multiple nodules is not a good predictor of malignancy.
An epidermoid cyst or epidermal inclusion cyst [1] is a benign cyst usually found on the skin. The cyst develops out of ectodermal tissue. Histologically , it is made of a thin layer of squamous epithelium .
This cystic lesion has a peripheral enhancing wall, which becomes more thick over its inferior aspect associated with surrounding fat stranding at the surgical site (white arrow). There are no internal septations, nodules or masses, or calcifications. c Transverse view of power Doppler ultrasound at the submental area demonstrates cystic lesion ...
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
A CT scan shows both calcified and uncalcified cysts, as well as distinguishing active and inactive cysts. Cystic lesions can show ring enhancement and focal-enhancing lesions. Some cystic lesions, especially the ones in ventricles and subarachnoid space may not be visible on a CT scan, since the cyst fluid is isodense with cerebrospinal fluid ...
Ciliated cyst of the vulva (cutaneous Müllerian cyst, paramesonephric mucinous cyst of the vulva) Clear cell acanthoma (acanthome cellules claires of Degos and Civatte, Degos acanthoma, pale cell acanthoma) Clear cell squamous cell carcinoma (clear cell carcinoma of the skin) Chronic scar keratosis (chronic cicatrix keratosis) Clonal ...
Lesions are often classified by their tissue types or locations. For example, "skin lesions" or "brain lesion" are named for the tissue where they are found.If there is an added significance to regions within the tissue—such as in neural injuries where different locations correspond to different neurological deficits—they are further classified by location.
Dermatofibromas are classed as benign skin lesions, meaning they are completely harmless, though they may be confused with a variety of subcutaneous tumours. [7] Deep penetrating dermatofibromas may be difficult to distinguish, even histologically, from rare malignant fibrohistocytic tumours like dermatofibrosarcoma protuberans .
