What Causes Bumps On Dogs Skin

Skin bumps - possible causes

Bumps in the skin can have a number of causes. The simplest is that you bumped yourself. Diseases can also hide behind skin bumps and lumps in the skin.

Bumps in the skin are bumps or lumps in the skin that are larger than a simple pimple. They can be many and varied, especially in terms of size.

Causes of primary skin bumps

Skin bumps develop without affecting other parts of the body or causing a disease.

  • The simplest and easiest to understand explanation of a bump is that you hit yourself. Usually you will hear the collision right away (unless it happens while you sleep). Such a bump is not a problem and will subside after a few days. It is often accompanied by a bruise. Bumps on the head require special care. If you feel dizzy or nauseous after the collision or if you even have a "film tear", you must consult a doctor. A concussion may have resulted from the collision.
  • The lipoma is a benign adipose tissue tumor. It shows up as a small hard spot under the skin. If it is bigger, it shows up as a bump. Lipomas are harmless. They only have to be removed if they are cosmetically disturbing or if they are so large that they press on vessels or nerves or restrict movement.
  • Fibroids can also cause skin bumps. These are benign tumors of the muscle tissue. They appear as deep bumps under otherwise healthy skin.
  • A deep pimple can cause a small bump. Most of the time, the pus comes to the surface and the pimple opens. One senses the accumulation of pus in the depths of the skin.
  • Inflammation of the hair follicle is called a boil. It causes a red swelling of the surrounding skin. The pus-yellow center around the hair is characteristic. A boil should receive medical attention. If several neighboring boils combine, a carbuncle is created. This is definitely in need of treatment. The frequent occurrence of boils can be an indication of a disease, for example diabetes mellitus.
  • A bulge scar is called a kelloid. It is a benign growth of the connective tissue. Celloids can occur, for example, after burns or chemical burns or after surgical scars. Celloids can be painful and itchy and restrict movement near the joints. Therapy in the form of another operation is difficult because the kelloid usually comes back.

Malignant tumors under the skin

Bumps in the skin can hide not only benign tumors such as lipomas or fibroids, but also malignant ones.

  • A malignant tumor that originates from adipose tissue is liposarcoma, which must be surgically removed. A medical differentiation between lipoma and liposarcoma is therefore essential, especially since the two cannot be distinguished externally.
  • The muscle tissue can also develop malignant tumors. It's called myosarcoma.
  • If the malignant tumor originates from bone tissue, it is called an osteosarcoma. The bone can cause small to large bumps under the skin if the affected area swells. Osteosarcomas mainly occur in children and adolescents.

Bumps as symptoms of other diseases

Skin bumps can be side effects of other diseases.

  • Edema is a build-up of fluid in the tissue. Edema can result from impaired lymph drainage, for example after surgery. One then speaks of lymphedema. Edema can also occur with cardiac or renal insufficiency and many other diseases. If you press into an edema, a dent remains.
  • Myxedema is a special form. In myxedema, the body does not store water, but sugar molecules. Often the myxedema occurs as a skin bump on the shins, but also on the face. The background may be an underactive thyroid or Graves' disease (hyperthyroidism). With myxedema, there is no dent left when you press into it.
  • Erythema nodosum occurs particularly on the shins. It is a reddish to yellowish-greenish nodule that is very tender on pressure. Erythema nodosum can be a side effect of Crohn's disease, tuberculosis or sarcoid. Intestinal or respiratory infections can also be the cause.
  • In rheumatic diseases such as rheumatoid arthritis, so-called rheumatic nodules can occur. They are hard knots on the extensor sides of the forearms.

Skin bumps that were not caused by a collision or that are obviously deep-seated pimples should definitely be examined by a doctor. It can be harmless such as a lipoma, but it can also indicate dangerous diseases such as liposarcoma or tuberculosis.
