Alopecia, Hormone, German Spitz, DermatopathyAbstract
Alopecia X is a hormonal dermatopathy that affects mainly Nordic breeds and has as its characteristics the occurrence of bilateral and symmetrical, melanodermic non-inflammatory alopecia. It does not affect the distal region of the limbs and head, mainly affecting the cervical, dorsal and perianal regions. The diagnosis is based on the clinical signs that the animal presents in the exclusion of endocrine dermatopathies such as hyperadrenocorticism and hypothyroidism, in laboratory tests and in cutaneous biopsy. Treatment consists of castration, melatonin, trilostan and/or growth hormone. Recently, microneedling has been a viable alternative in patients with alopecia X. The present work aimed to report the use of the microneedling technique in dogs with alopecia X. Two male German Spitz dogs, 2 and 5 years old respectively, with alopecia and melanodermia in the dorsum and flank region and cervical, caudal and perianal region for more than 2 years were followed. After being characterized as alopecia X patients, the animals were conducted to the microneedling technique, exhibiting repopulation in the alopecia areas. The conclusion is that microneedling is a promising technique for the treatment of alopecia X.
