Surgical sebaceous cyst

Introduction to surgical sebaceous cyst Sebaceous gland cysts, commonly known as "powder tumors", refer to the formation of cysts in the glands due to the accumulation of sebaceous glands after obstruction of the sebaceous gland ducts. This is the most common kind of benign tumor of the skin. Many people have had the experience of long powdery tumors, especially those who are in a period of strong growth and development. basic knowledge The proportion of sickness: 0.0004%-0.0007% Susceptible people: young people Mode of infection: non-infectious Complications: sebaceous gland cancer sebaceous gland adenoma sebaceous cyst disease sebaceous gland cancer

Surgical sebaceous cyst

The glandular glands of the sebaceous glands are blocked for various reasons, resulting in the accumulation of sebaceous glands to form a cyst.

Surgical sebaceous cyst prevention

Powder tumor is a benign tumor, generally does not malignant, but usually surgical resection is good. If left untreated, the cyst rupture will temporarily subside, but it will form scars and is prone to recurrence.

Surgical sebaceous cyst complications Complications Sebaceous gland cancer Sebaceous gland adenoma Sebaceous cyst disease Sebaceous gland cancer

Sebaceous gland cysts are often complicated by infection, causing the cyst to rupture and temporarily subside, but it will form scars and is prone to recurrence. The chance of carcinogenesis of sebaceous cysts is extremely rare.

Surgical sebaceous cyst symptoms Common symptoms Blackhead acne cystic acne

Pea, chestnut or fist size, spherical or hemispherical cyst, hard texture, high leather surface, mobility, clear boundary, no change in skin surface or compression and thinning, single or several aggregation, due to secondary infection The sputum and sputum, scalp, face, scrotum, shoulder and back are good hair. When infected, the surface of the cyst and the surrounding tissue have an inflammatory reaction, which is characterized by redness, pain, and oozing like a bean curd.

Surgical sebaceous cyst examination

Generally, no laboratory examination is required, and basic examination can be performed when the tumor is operated.

Diagnosis and differentiation of surgical sebaceous cyst

diagnosis

1. It often occurs in adult head, face, back or buttocks. It grows slowly and has no symptoms. When it is infected, it may have redness, swelling, heat and pain.

2. The cyst is round, the boundary is clear, the base can be pushed, adheres to the skin, and the capsule is sexy. Black follicular pores are sometimes seen in the center, and white sebum flows out after extrusion or rupture.

Sebaceous gland cysts occur in the scalp and face, followed by the trunk. Because of their different shades and different contents, the volume varies from one to another, and the size is small, such as the size of the rice and the size of the egg. It is diagnosed as a lipoma, fibroid, etc. The sebaceous gland cyst grows very slowly, but the patient can still feel that it is gradually increasing.

Sebaceous gland cysts are mostly single, occasionally multiple, round in shape, medium or elastic, higher than the leather surface, smooth surface, feel connected to the surface when pushed, but no adhesion to the substrate, no fluctuation, skin color may be normal It may also be light blue. When it is too fast, the surface of the skin can be bright. Sometimes there is an opening on the surface of the skin. From this, the white bean curd-like content can be squeezed out. This opening is the opening to the sebaceous gland on the skin surface. The open pit is caused by insufficient length of the catheter. The sebaceous gland cyst is often complicated by infection, causing the cyst to rupture and temporarily disappear, but it will form scars and is prone to recurrence. The chance of sebaceous cysts becoming cancerous is extremely rare.

Differential diagnosis

Identification with leiomyomas, dermoid cysts and epidermoid cysts:

Leiomyomas, also known as dermatomas, are benign tumors. They have three clinical types: single vascular leiomyoma, single genital leiomyomas, and multiple leiomyomas. The former is derived from vascular smooth muscle. The skin lesions are dark or subcutaneous solid nodules of needles or soybeans, which can be merged into flat plaques, which are higher or lower than the leather surface and can be moved; it is more common in the lower limbs, especially in the calf flexion; young women are more common. Crowd; there is a paroxysmal tingling sensation, which can be induced by cold, exercise, oppression, and emotional arousal. Single genital leiomyosarcoma originates from the scrotal intima, vulva or papillary muscles; skin lesions are mostly single yellow beans. Solid nodules, removable; occur in adults over 30 years old, have pain, multiple skin leiomyomas, originated from the vertical hair muscles, skin lesions from the needle to the bowl of solid size round nodules, removable, dark Red or maroon, blue-red, clustered or fused into tablets; more often on the back, face and extremities, more common in people over the age of 30; long-term may have sensitive pain.

Dermoid cyst: located under the skin, does not adhere to the skin and adheres tightly to the basal tissue, often in the vicinity of the body line, occurs around the eyelids, nose, occipital and fundar.

Epidermoid cyst: It is a cyst with keratin in the dermis. It is often caused by trauma (especially stab wound). The epidermis is often implanted into the dermis. The surface of the mass often has horny hyperplasia, which is easy to be traumatized by hands and ankles. The part of the oppression.
