Prolonged remission after immunosuppressive therapy in six dogs with pemphigus foliaceus.

Limited information is available on the long-term outcome of treatment of pemphigus foliaceus in dogs. The purpose of this study is to report that a prolonged remission can occur after discontinuation of immunosuppressive regimens in some animals with this disease. Six dogs were diagnosed with pemphigus foliaceus based on suggestive clinical signs and histopathology.

The histology of normal llama skin.

Skin biopsy specimens of normal llama skin were examined histologically. Adnexal structures similar to those of most other domestic mammals included epitrichial sweat glands, sebaceous glands and arrector pili muscles. Unique features of normal llama skin included a very thick dermis with marked differences between superficial and deep dermis, prominent cutaneous vascular plexuses, unidentified cells with eosinophilic granules within the adventitia of the vascular plexuses, both simple and compound hair follicles, 'metatarsal glands', 'interdigital glands', footpad glands and the absence of eyelid tarsal glands.

Paraneoplastic alopecia associated with internal malignancies in the cat.

Abstract  A paraneoplastic alopecia associated with internal malignancy is reported in four cats. Acute, bilaterally symmetrical, ventral glistening alopecia, weight loss and lethargy were present in all cats. Skin biopsy specimens exhibited severe follicular and adnexal atrophy with follicular miniaturization, minimal inflammation and, in many cases, absence of stratum corneum.
