Is poroma benign?
Poroma is a benign tumor, mostly asymptomatic, and the prognosis is usually good. Patient education regarding malignant transformation, i.e., porocarcinoma is not necessary because its risk is similar to normal skin.
What causes poroma?
A poroma is a relatively rare benign adnexal neoplasm that originates from the intra-epidermal portion of the sweat gland duct (the acrosyringium). It is thought to arise from the eccrine sweat gland, but apocrine features may be seen.
What is an eccrine poroma?
Eccrine poroma was first reported by Pinkus in 1956 and represents 10% of all sweat gland tumors. [1] It is a benign neoplasm originating from the intraepidermal ductal portion of the eccrine sweat duct.
What is adnexal tumor?
Listen to pronunciation. (ad-NEK-sul…) A lump in tissue near the uterus, usually in the ovary or fallopian tube. Adnexal masses include ovarian cysts, ectopic (tubal) pregnancies, and benign (not cancer) or malignant (cancer) tumors.
Is Porocarcinoma cancerous?
Porocarcinoma is a rare sort of skin cancer developing from sweat glands, specifically, it is a malignancy of the eccrine sweat glands [1]. Its etiology is not well understood. However, some studies have showed that the tumor developed from a pre-existing eccrine poroma.
How is Porocarcinoma treated?
Conclusions. Porocarcinoma is an aggressive skin cancer. Surgery is the main modality of treatment.
Do Poromas need to be excised?
The diagnosis and treatment of poromas is typically performed via simple complete excision.
Is adnexal mass cancerous?
Adnexal Mass (Tumors) 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 the treatment for adnexal mass?
Treatment options for adnexal masses vary depending on the specific diagnosis. Some masses can be treated conservatively, and others may require surgery. Observation is generally recommended when the appearance of the adnexal mass on ultrasonography suggests a benign growth.
What is a Trichofolliculoma?
Trichofolliculoma represents an uncommon hamartoma of hair follicle tissue, typically occurring on the face of adults. Notably, trichofolliculomas have been reported on the eyelids, auricle, and external auditory canal. [2, 3, 4] Clinical appearance of trichofolliculoma.
Can Hidradenoma become malignant?
Nodular hidradenoma (NH) is a benign adnexal tumor that arises from the distal excretory duct of eccrine or apocrine sweat glands [1]. Despite its well-defined histological features of benignity, long-standing NH has been reported to undergo malignant transformation to malignant NH (MNH) [2].
Is Porocarcinoma genetic?
While in poromas only few cases showed single mutated genes, porocarcinomas showed greater genetic heterogeneity with up to six mutated genes per case. Recurrent TP53 mutations were found in all porocarcinomas that harboured mutated genes.
What is metastatic Porocarcinoma?
Abstract. Eccrine porocarcinoma (EPC) is a rare tumor. It develops from the intraepidermal ductal portion of the eccrine sweat gland. Metastatic disease is rare. We report a new case of metastatic eccrine porocarcinoma with a successful management and a good response to docetaxel.
How do you remove adnexal mass?
With advancements in minimally invasive, robotic-assisted technology, adnexal masses can be removed via laparoscopic surgery using the da Vinci Surgical System. In the female reproductive system, the area where the uterus, fallopian tubes, and ovaries connect is called the adnexa.
