Dermoid sinus, rare skin condition in dogs

schematische voorstelling dermois sinus

Dermoid sinus is an inherited autosomal skin condition in dogs. It is also known as pilonidale sinus. It seems from the outside on a pilonidale sinus as found in humans; a cavity in the skin, also called fistula. But in dogs it is another anomaly, since the cause is a neural tube defect.

A dermoid sinus is rare in dogs and cats. It can appear as single or multiple nodules on the dorsal midline. The sinus is caused in the embryonic stage of development. In normal development, the developing neural tube from which the backbone separates from the skin. In a sine wave, this separation is not fully taken place. The result is that in some cases the dermoid sinus remains connected to the spinal cord of the animal; in other cases, the sinuseindigt in a "blind sac" that is less dangerous to remove. Dermoid sinus may contain hair follicles, sebaceous glands and sweat glands. If the sinus becomes infected, this can lead to meningitis (meningitis) and myelitis (inflammation of the spinal cord). Symptoms are stiffness, pain and fever. In severe cases, the condition can be life threatening.

The inheritance of dermoid sinus is generally seen as a single recessive, meaning an animal with both parents must stringing a defective gene to develop the disorder. If one parent carries the gene and the other does not, the puppies will be carriers and in turn posterity this gene may doorgeven.Door some, the condition is seen as dermoid sinus polygenic, meaning that there are multiple genes involved are at the root cause. How it must also inherit, generally the hereditary nature is automatically advised of animals that use this condition have not breeding.
Surgical removal is the only cure for this disease, where a veterinarian will remove the abnormal tissue and, if possible, close the divide in the back that were still open at d egeboorte. In some instances, regrowth of the sinus occurs on. Advance can be examined how deep the sinus with contrast. There should always be additional tests to be done to see if there are side effects have occurred, such as inflammation in hidden places in the body. For this, blood counts should be examined.
If necessary, can be examined with a MRI or neurological symptoms exist as a result of the sine wave.
Races where this deviation occurs and which is known for the genetic variant is in any case: Rhodesian Ridgeback and Thai Ridgeback, Kerry Blue Terrier, Shih Tzu and Boxer.
Dermoid sinus is sometimes also confused with dermoid cyst.
