Is sebaceoma malignant?

Is sebaceoma malignant?

Sebaceoma is a benign tumor composed of incompletely differentiated sebaceous cells of varying degrees of maturity. Sebaceomas was never reported as a known premalignant lesion.

What is a sebaceoma?

(seh-BAY-shee-OH-muh) A benign yellow or flesh-colored lesion originating from an oil gland in the skin. Sebaceomas are typically found on the face or neck. They may be associated with Muir-Torre syndrome, which is a hereditary syndrome associated with the development of several types of cancer.

What is Muir-Torre syndrome?

Muir–Torre syndrome is a rare, autosomal-dominant, genetic condition. It is defined by the occurrence of sebaceous tumours (sebaceous adenoma, epithelioma or carcinoma and/or kerato-acanthoma) and visceral malignancies. The most common visceral malignancy associated with Muir–Torre syndrome is colorectal cancer.

Where is sebaceous carcinoma found?

Sebaceous carcinoma is a type of cancer that begins in an oil gland in your skin. It most often affects the eyelid and may cause a lump or skin thickening. Sebaceous carcinoma is a rare type of cancer that begins in an oil gland in the skin. Sebaceous carcinoma most often affects the eyelids.

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 a Basaloid cell?

INTRODUCTION. Basaloid Squamous Cell Carcinoma (BSCC) is a rare and aggressive variant of oral squamous cell carcinoma (OSCC) that was first identified as a separate histopathological entity by Wain et al. ( 1986).[1,2] It is regarded as a high-grade tumor with increased propensity for metastasis to distant sites.

What causes sebaceous carcinoma?

Most people diagnosed with sebaceous carcinoma are between 60 and 80, though the disease can affect all ages. There are several suspected risk factors: Unprotected sun exposure. Weakened immune system from medical conditions like human immunodeficiency virus (HIV) or cancer.

Is eccrine a 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.

Is Muir-Torre syndrome rare?

Muir-Torre syndrome (MTS) is a rare disorder, with approximately 200 patients reported.

Is sebaceous carcinoma fast growing?

In general, extraocular sebaceous carcinoma is less aggressive than ocular sebaceous carcinoma [4]. However, some authors have reported that extraocular tumors preferentially show a rapid growth. This is especially true in elderly women [6]. In the present patient, the lesion was rapidly growing in just 2 weeks.

What is the history of sebaceoma?

The term sebaceoma was introduced in 1984 by Troy and Ackerman to describe a benign adnexal tumor differentiating toward sebocytes, distinct from sebaceous hyperplasia, sebaceous adenoma, basal cell carcinoma with sebaceous differentiation and sebaceous carcinoma.

What is the difference between sebaceous epithelioma and sebaceoma?

Sebaceoma was meant to redefine the previously used and confusing term “sebaceous epithelioma,” which was not well defined in the literature. Lesions typically occur on the face and scalp, although cases on the chest, back and neck have been described. Sebaceoma can arise in a pre-existing nevus sebaceus.

What is a sebaceoma in breast cancer?

Clinically sebaceomas are typically solitary, yellow-orange papules or nodules that range in size from 6 mm up to 3 cm in diameter. Recognition of this tumor is important as it can be associated with Muir-Torre Syndrome (MTS).

What are the variants of sebaceoma?

Variants of sebaceoma have been described with carcinoid-like, reticulated, cribriform, rippled and Verocay body-like features If playback doesn’t begin shortly, try restarting your device.
