The usefulness of dermoscopy in canine pattern alopecia: a descriptive study

Abstract

Although canine pattern alopecia is a visually striking disease, this study supports the value of dermoscopy for clinical examination and also opens promising perspectives for the identification of diagnostic dermoscopic patterns that may be useful for other skin disorders.

Dermoscopic analysis of the skin of healthy warmblood horses: a descriptive study of 34 cases in Italy

“…In veterinary medicine there are few studies regarding the use of dermoscopy. The normal dermoscopic appearance of feline and canine skin has been described and characteristic dermoscopic features of small animal conditions such as feline dermatophytosis, canine demodicosis and canine pattern alopecia have been reported . With the exception of one abstract regarding the dermoscopic appearance of a verrucous lobular capillary haemangioma in a horse, there are no studies, to the best of the authors' knowledge, that detail the application of dermoscopy in equine dermatology.…”

Alopecia Areata in a Dog: Clinical, Dermoscopic and Histological Features

“…The observed features are indicative of a hair growth disturbance but are not specific. Yellow-brown dots that represent follicular infundibulum filled with sebum and keratin have also been reported in canine pattern alopecia [14], canine demodicosis [15] and also observed in some disorders of hair follicle cycling as hypercortisolism (unpublished data). Broken hairs are also a nonspecific finding and are also observed in friction alopecia (self-induced).…”

“…Comma-like hairs have been described as the main characteristic features both in cats and dogs with dermatophytosis [11,12,13]. Canine pattern alopecia has been evaluated by dermoscopy in 20 short-haired dogs [14] and hair shaft thinning, scattered circle hairs, plugging of the follicular infundibulum with a yellow-brown material and honeycomb-like pattern pigmentation in sun-exposed areas were reported as the prevalent features.…”

Evaluation of hair follicle parameters using TrichoScale Pro© in healthy dogs: a pilot study

“…As the canine hair coat is particularly complex, given the compound nature of the hair follicles and mosaic growth pattern, the common methodologies for canine hair follicle assessment – trichography, skin biopsies and manual hair trimming measurements – come with respective limitations. Skin biopsies are considered the gold standard for hair follicle evaluation, but although undoubtedly valuable, the results often are fraught with diagnostic uncertainty …”
