There is a hard lump on the side of my butt

Sometimes, some hard lumps often appear on our bodies. Because these big bags don't have any adverse reactions, many people don't care. For example, a hard lump grows on the side of the buttocks. So does anyone know what the reason is? In fact, this kind of bag is likely to be a "pimple". That is a kind of external hemorrhoids. Generally speaking, cysts can be treated conservatively and surgically.

Pyrosis

Pyroma is also known as sebaceous cyst. The cause of the disease is the obstruction of the sebaceous gland duct, which leads to the congestion of sebaceous gland excretion. Obstruction of sebaceous gland ducts is mostly caused by dust blockage and bacterial infection.

Symptoms: Sebaceous cysts protrude from the surface of the skin and are prone to occur in areas rich in sebaceous glands, such as the scalp, face, chest and back, and most grow slowly. When there is no concurrent infection, patients generally have no symptoms. The tumors are spherical, single or multiple, and vary in size, ranging from a few millimeters to nearly 10 centimeters. It is of medium hardness and elasticity, protruding from the skin surface, adhered to the skin, not easy to push, with a smooth surface and no sense of fluctuation. There is a needle-head-sized umbilicus-like opening in the center, which is blue-black in color and shaped like a needle-head acne. Squeezing can produce tofu dregs or noodle mud-like contents, which are sebum and broken sebaceous gland cells, often with a rancid odor. It is extremely rare for sebaceous cysts to become cancerous, but they are prone to secondary infection. If infection occurs, inflammatory reactions such as redness, swelling, heat, and pain may occur. The cyst may rupture and temporarily disappear under external force, but it will form scars and is prone to recurrence.

1. Conservative treatment

The skin lesion area is routinely disinfected, and a 9-16 gauge needle is used for cyst cavity puncture according to the size of the cyst. Because the contents are thick and difficult to extract, an appropriate amount of saline solution needs to be injected to dilute it. During the operation, physiological saline can be repeatedly injected to dilute and flush the cystic cavity, and the contents of the cystic cavity can be drained out as much as possible. After the cyst cavity contents are evacuated, inject about 1 to 3 ml of a mixture of Xiaozhiling injection and 2% lidocaine injection (prepared before use in a 1:1 ratio) according to the size of the cyst. The amount of mixed injection solution injected is preferably about 1/3 of the volume of the cyst cavity. After injection, massage the local area for 3 to 5 minutes, fold the medical sterile gauze into the same size as the tumor and cover the tumor with pressure to fix it. Remove the gauze after 2 days and observe the therapeutic effect after 4 weeks. If the effect is not satisfactory, another injection can be given. If the third injection is ineffective, surgical treatment can be performed instead.

2. Surgery

Sebaceous cysts should be surgically removed when they are not infected.

Preoperative preparation: Shave the local skin and clean it.

Anesthesia: Local anesthesia.

Surgical steps: Make a fusiform incision with the cyst as the center, and remove the skin flap together with the cyst; if the cyst is small, a straight incision can be made. After cutting the subcutaneous tissue, use tissue forceps to flip up one end of the skin flap, gently lift the tumor, and then use tissue scissors (or hemostatic forceps) to separate it along the edge of the cyst to make it completely free; the fibrous cords at the bottom of the cyst can be clamped, cut and ligated with hemostatic forceps to completely remove the cyst. After the wound is flushed and bleeding is stopped, the incision is sutured in layers and a slight pressure bandage is applied.
