What Is the Gluteal Tuberosity?

Nodules are palpable localized round, oval, or irregularly shaped substantial skin lesions. Nodule formation can be inflammatory or non-inflammatory, can involve the epidermis, dermis or subcutaneous tissue, vary in size, as small as millet, as large as cherry or larger, and can fuse with each other to become plaque.

Common causes

Specific or non-specific inflammation can cause

Common symptoms

It can be touched but not visible at the beginning, and then gradually increases and rises above the leather surface, with both soft and hard textures

Nodule cause

Both specific and non-specific inflammation can cause nodules. Nodules can be related to parasite invasion and accumulation of metabolites, and some nodules can be a new organism. Basal cell carcinoma, skin tuberculosis, tertiary syphilis, and cysticercosis can be associated with nodules.

Clinical manifestations of nodules

Different skin diseases have different nodules. Basal cell carcinoma nodules can be located in the epidermis; some nodules can be located in the epidermis and dermis; nodules of skin tuberculosis, tertiary syphilis, and deep mycosis can be located in the dermis and subcutaneous tissue; lipomas, porcine cysticercosis Nodules can be located in the subcutaneous tissue.
The nodules can be touched but not visible at the beginning, and then gradually increase and rise above the skin. The texture of the nodules is both soft and hard. Some nodules are insensitive to touch, indicating adhesion to surrounding tissues, and most skin tumors appear as nodules. Syphilis gum is a special type of nodule with granulomatous changes. Inflammatory patients such as nodular erythema may be accompanied by pain, and non-inflammatory new organisms may have no symptoms. A few nodules can be completely absorbed by themselves without leaving traces. Most nodules change slowly or gradually increase, and some can ulcerate and form ulcers. After healing, there are scars.

Nodule inspection

Examination is mainly palpation, which can directly determine the presence or absence of nodules.

Nodule diagnosis

The main points of diagnosis are as follows.
1. Palpate palpable parenchymal skin lesions that are limited to round, oval, or irregular, that is, nodules.
2. Ask the medical history, the patient may have a history of basal cell carcinoma, skin tuberculosis, tertiary syphilis, porcine cysticercosis and so on.

Nodular Treatment

The treatment of nodules is mainly for the primary disease.
1. Basal cell carcinoma There are many treatments for basal cell carcinoma. The most important thing is to choose the best treatment plan based on the patient's condition. Treatment methods include surgical resection, X-ray irradiation, electrocautery, sharp key curettage, liquid nitrogen freezing, and laser treatment.
2. Skin tuberculosis Systemic use of anti-tuberculosis drugs, drugs and treatments are based on whether there is visceral tuberculosis.
3. For the treatment of benign advanced syphilis (vascular, mucosal, bone, etc.) in stage III syphilis, intramuscular injection of procaine penicillin G, or intramuscular injection of benzathine penicillin. For cardiovascular and central nervous system syphilis, benzathine penicillin is not used and procaine penicillin is injected intramuscularly.
4. Porcine cysticercosis praziquantel and albendazole are the main anti-cystic cysticercosis drugs. They are suitable for active and partially degenerative death of cysticercosis in pigs. Have better results.
