Alopecia areata (pelade) in a cow
The Canadian Veterinary Journal = La Revue Veterinaire Canadienne
|September 1, 1988
Summary
This study describes alopecia areata, a rare skin condition in cattle causing hair loss. Diagnosis involves skin biopsies, and while no effective treatment exists, it typically doesn't impact the animal's health or production.
Area of Science:
- Veterinary Dermatology
- Animal Pathology
Background:
- Alopecia areata (pelade) is an uncommon, idiopathic skin disease affecting cattle.
- It presents as non-inflammatory, asymptomatic patches of hair loss.
Purpose of the Study:
- To describe a case of alopecia areata in a cow.
- To detail the diagnostic methods and clinical presentation of this condition in cattle.
Main Methods:
- Clinical examination of the affected cow.
- Diagnostic procedures including skin scrapings and cultures.
- Histopathological examination of skin biopsies from early lesions.
Main Results:
- The case presented with solitary and multiple annular areas of alopecia.
- Skin scrapings and cultures were negative for infectious agents.
- Biopsies revealed lymphocytic infiltration around anagen hair follicles, confirming alopecia areata.
- No significant impact on the animal's general health or production was observed.
Conclusions:
- Alopecia areata in cattle is a cosmetic concern with no known effective treatment.
- The condition is characterized by specific histopathological findings.
- Spontaneous remission is possible, and the disease does not generally affect animal welfare or productivity.

01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:39Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
