> Ferrets are important companion animals that incur a multitude of
> cutaneous diseases requiring diagnostic dermatohistopathology. This
> study provides a description of the histology of normal ferret skin,
> emphasizing changes in the interval from preweaning to adulthood, an
> essential basis for identification of pathological situations. Skin
> samples obtained post-mortem from 29 topographical sites on 41
> ferrets, revealed in the haired, general body surface skin an
> epidermis consisting of strata basale, spinosum, granulosum, and
> corneum and a dermis consisting of strata papillare and reticulare.
> Adult skin contained compound hair follicles composed of one primary
> hair and a collection of secondary hairs with a primary to secondary
> ratio of 1/5-1/15. All hairs emerged through the same follicle
> outlet of the skin surface. There was associated with each primary
> follicle, an arrector pili muscle, a multilobular sebaceous gland,
> and a coiled tubular sweat gland, but secondary hairs lacked these
> features. Compound follicles, grouped mainly as triads across the
> body surface, were already fully formed in the youngest group
> studied (3 to 6 weeks). The secondary hairs all developed from one
> specific region of the primary follicles and smaller ones were
> formed with increasing age. The differences found in specialized
> body regions are described. Demodex sp. mites were found in
> follicles and sebaceous glands in nine of 25 individuals in the
> perianal, vulvar, preputial, facial, and caudal abdominal skin.
