What are the symptoms of sebaceous adenoma

1. Symptoms:

It is usually a single skin-colored papule or yellowish papule or nodule with no clinical diagnostic features. Commonly seen in male patients aged 50 to 60 years.

1. Predisposing areas: Mostly on the scalp, face, or neck.

2. Clinical symptoms: manifested as round, solid nodules, generally less than 1 cm in diameter. The surface is smooth and appears light red, yellow-red or normal skin color. Usually single, occasionally multiple.

2. Diagnosis:

1. This disease is generally not difficult to diagnose. The diagnosis can be made based on clinical manifestations, characteristics of skin lesions, and histopathological features.

What is sebaceous adenoma?

1. Causes of disease:

1. A benign tumor caused by the enlargement of incompletely differentiated sebaceous glands.

2. Pathogenesis

Microscopically, the tumor tissue has a clear boundary with the surrounding tissue and often has a capsule composed of incompletely differentiated sebaceous gland lobules. Sebaceous gland lobules vary in shape and size. There are two main types of tumor cells:

1. Small alkaliphilic cells, identical to the germinal cells surrounding the normal sebaceous gland lobules.

2. Mature vacuolated sebaceous gland cells, identical to the cells near the center of a normal sebaceous gland lobule. Fat staining showed lipids in mature sebaceous gland cells.

Sebaceous adenoma is usually a solitary skin abnormality, usually a papule-like tumor that is different from the skin color or a yellowish papule or nodule. This type of sebaceous adenoma usually occurs in people between the ages of 50 and 60, especially in men. This type of sebaceous adenoma usually occurs on the scalp, face or neck, and rarely occurs in other parts of the body. This type of adenoma also appears as a round, solid nodule that usually does not grow too large, and is usually a tumor-like protrusion smaller than one centimeter. The surface of the tumor is smooth, and in addition to yellow, it may also be light red or appear normal skin color. Multiple episodes may also occur.

Sebaceous adenoma and sebaceous cyst are different. Sebaceous adenoma is a benign tumor caused by the enlargement of poorly differentiated sebaceous glands. Generally, this type of adenoma is not large in size and comes in several different colors. Although it usually occurs alone, it can also occur in multiples. Generally, it can be removed surgically through a variety of methods without causing serious consequences. However, sebaceous cyst is not a true tumor. It is usually formed due to blockage of the external opening of the sebaceous gland. This type of cyst often occurs on the head and in areas where sebaceous glands are concentrated. Sebaceous cysts can also cause symptoms of infection. After infection, anti-inflammatory treatment must be carried out before removal, but symptoms of recurrence are likely to occur after removal. Therefore, you need to check your condition at any time.
