Pet Health Concerns: Dermoid Sinus

Dermoid sinus is a rare, genetic, and autosomal skin condition in both cats and dogs. This neural tube defect occurs during development and the spinal cord does not separate from the skin before birth. Dermoid sinus appears as a lump or several lumps along the dorsal mid-line of the pets body. There are possible instances of meningitis or myelitis causing pain, fever, and body rigidity to occur if the sinus becomes infected. This dermoid sinus usually contains hair follicles, sweat glands, and sebaceous glands inside of it.  Although this condition is rare in cats and dogs, and can affect several breeds, the most common dog breed that experiences this condition is the Rhodesian Ridgeback. Surgery is a common treatment for this genetic condition, however, most pets are able to live a healthy and happy life with it if surgery is not an option. Treatment costs may vary from $200-$1,500.
