What is eccrine acrospiroma?

What is eccrine acrospiroma?

Eccrine acrospiroma are benign skin tumours of sweat duct origin. They usually present as small solid or cystic lesions which are confused clinically with other solid or cystic lesions. These are generally benign lesions with few reports of malignant transformation.

What is an eccrine Spiradenoma?

An eccrine spiradenoma is a rare tumor of the eccrine sweat glands and was first described by Kersting and Helwig [4 ]in 1956. In their study of 134 eccrine spiradenomas, more than 97% of the tumors were solitary blue-red dermal or subcutaneous nodules, ranging from 0.5 to 3 cm in diameter.

What is a Hidradenoma?

Hidradenoma is a relatively rare tumor of sweat gland origin. Although traditionally regarded as displaying eccrine differentiation, it is now accepted that tumors can show either eccrine or apocrine differentiation. [1,2] This tumor found mainly in adults, and is excised more commonly in women than in men.

Is a poroma benign?

A poroma is a benign neoplasm that shows differentiation toward poroid (glandular ductal) cells. The malignant counterpart of poromas is porocarcinoma, which also shows poroid differentiation. Poromas occur only in the skin and are not known to affect any other tissues.

Is eccrine Spiradenoma benign?

Spiradenomas are benign neoplasms originally thought to arise from sweat glands in the dermal layer of the skin. They were first described in 1956 by Kersting and Helwig as a distinct form of sweat gland tumor ,which they called eccrine spiradenoma.

What causes eccrine Spiradenoma?

Spiradenomas appear to be caused by a defective tumor suppressor gene. A mutation in the CYLD gene on chromosome 9 is found in Brooke-Spiegler syndrome, which features multiple spiradenomas.

What causes eccrine poroma?

Eccrine poroma is a benign tumor which arises from the intraepidermal portion of the eccrine sweat glands. It usually occurs as a solitary lesion in the extremity, with the foot and sole as a common site. It may present as a foot mass, ulcerative lesion, bleeding lesion, or suspected melanoma.

What is the meaning of poroma?

A poroma is a benign skin tumor derived from sweat glands. Although the original term poroma was initially used to describe a tumor derived from the ductal epithelium of eccrine sweat glands, the term is used in general reference to tumors derived from ductal portions of both eccrine and apocrine sweat glands.

What is a eccrine gland?

(EK-rin …) A type of simple sweat gland that is found in almost all regions of the skin. These glands produce sweat that reaches the surface of the skin by way of coiled ducts (tubes). The body is cooled as sweat evaporates from the skin.

Is eccrine spiradenoma cancerous?

Background: Eccrine spiradenoma is a well-differentiated benign tumor of the sweat glands. Malignant change arising within eccrine spiradenoma is rare.

Is eccrine spiradenoma benign?

What are the clinicopathologic characteristics of eccrine porocarcinoma (EP)?

The clinicopathologic characteristics of 69 cases of eccrine porocarcinoma (EP) have been studied. Seven cases of purely in situ disease are included. Forty patients were female, 29 male with ages ranging from 29 to 91 years (mean 73 years). The lower extremity represented the single most common site (44%).

What is hidroacanthoma (acrospiroma)?

Hidradenoma or acrospiroma is a benign dermal growth closely related to poroma except without connection to the epidermis. Hidroacanthoma can also be of apocrine or eccrine origin. It appears as a solitary nodule (lump) or cyst (when it is called cystic hidradenoma) and may appear on any site.

What is eccrine carcinoma of the skin?
