One of the most important factors used to determine the clinical suspicion of malignancy of an adnexal mass is the sonographic appearance of the mass. [2] Indications that the mass is at a higher risk of being malignant include the presence of loculations, nodules , papillary structures, septations , or a size greater than 10 cm. [ 3 ] [ 4 ]
In dermatologic pathology, a dermal cylindroma, also dermal eccrine cylindroma or cutaneous cylindroma [1]: 666 ) and (less specifically) cylindroma, is a benign adnexal tumor [2] that occurs on the scalp and forehead. Multiple cylindromas may grow together in a "hat-like" configuration, sometimes referred to as a turban tumor. [3]
Cutaneous adnexal tumors are a large group of skin tumors that consist 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, apocrine sweat glands, and eccrine sweat glands. [3] CCS tumors are hair follicle tumors. [2]
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 ...
Poromas are benign tumors of the distal portion of sweat gland ducts.. Poromas are rare, benign, cutaneous adnexal tumors. [1] Cutaneous adnexal tumors are a group of skin tumors consisting of tissues that have differentiated (i.e. matured from stem cells) towards one or more of the four primary adnexal structures found in normal skin: hair follicles, sebaceous sweat glands, apocrine sweat ...
An adnexal mass is a significant finding that often indicates ovarian cancer, especially if it is fixed, nodular, irregular, solid, and/or bilateral. 13–21% of adnexal masses are caused by malignancy; however, there are other benign causes of adnexal masses, including ovarian follicular cyst, leiomyoma, endometriosis, ectopic pregnancy ...
Microcystic adnexal carcinoma (MAC) is a rare sweat gland cancer, [1] ... If the tumor spreads, it can grow and invade fat, muscles, and other types of tissue. [2]
Acrospiromas are a broad class of benign cutaneous adnexal tumors. [1] Cutaneous adnexal tumors are a group of skin tumors consisting of tissues that have differentiated (i.e. matured from stem cells) towards one or more of the four primary adnexal structures found in normal skin: hair follicles, sebaceous sweat glands, apocrine sweat glands, and eccrine sweat glands.
