What is skin adnexal tumor?

Adnexal tumors (ATs) are the tumors arising from the appendages of the skin such as sweat glands, sebaceous glands, and hair follicles. Adnexal skin tumors are usually misdiagnosed clinically, and histopathology usually provides diagnostic confirmation.

Are adnexal tumors malignant?

An adnexal mass forms near the uterus — in the ovaries, fallopian tubes or surrounding connective tissues. Most adnexal tumors are benign (noncancerous), but they can be malignant (cancerous). Many adnexal masses go away on their own, but some require treatment, which may include surgery.

What is adnexal epithelium?

Cutaneous adnexal tumors are a large group of benign and malignant neoplasms that exhibit morphologic differentiation towards one of the four primary adnexal structures present in normal skin: hair follicles, sebaceous glands, apocrine glands, and eccrine glands [1,2].

What are adnexal structures?

Adnexa are accessory structures which are involved in protecting and/or supporting the function of an organ. The eye and peri-ocular tissues are extremely specialised.

What is the treatment for adnexal mass?

The majority of adnexal masses aren’t harmful. They won’t require treatment unless a woman is experiencing uncomfortable symptoms. Many adnexal masses will resolve themselves without any intervention. In a very small number of cases, the cause of the adnexal mass will be ovarian cancer.

What adnexal means?

Adnexa is a Latin word meaning attachment or appendages. It refers to the ovaries, fallopian tubes, and ligaments that hold the reproductive organs in place. These are all located in your lower abdomen near your pelvic bone. Learn more about adnexal tenderness, including how to treat it.

What is Spiradenoma?

Spiradenomas are well-differentiated, benign, dermal neoplasms originating from the sweat glands. Most spiradenomas occur between the ages of 15 to 35 years. Typically, they present as small solitary nodules that can grow to several centimeters, often with a blue, gray, or purple hue.

What is a Trichoepithelioma?

Trichoepithelioma is a rare benign skin lesion that originates from hair follicles. Trichoepitheliomas are mostly seen in the scalp, nose, forehead, and upper lip. These skin lesions originate from benign proliferation of epithelial-mesenchymal origin cells.

Where is the adnexal mass located?

Adnexal tumors are growths near the uterus. They’re also known as adnexal masses. They usually form in the ovaries, which make eggs and hormones, or the fallopian tubes, which connect your uterus and ovaries. The tumors can form in the connective tissue around this part of your body.

What causes Cylindroma?

The cause of sporadic, solitary cylindromas is largely unknown; however, genetic studies of sporadic cylindromas show loss of heterozygosity at and around the CYLD locus in a substantial number of cases, suggesting that this gene also plays a role in the development of sporadic tumors.
