  • Discoid lupus erythematosus (DLE) is an immune-mediated skin disease which requires histopathology and immunohistopathology in both dogs and humans. A 10-month-old, intact female Alaskan Malamute presented for depigmentation, swelling, alopecia, erythema, and crusting on the bridge of the nose and the nasal planum. Cytological examination of nasal lesions revealed numerous cocci and neutrophils. Histopathological features included of infiltration of mononuclear cells at the dermoepidermal junction. Direct immunofluorescence tests and immunohistochemistry exhibited positive IgG, IgM, IgA, CD3, CD18, and CD79a on the epidermal basement membranes and around adnexal glands. This case indicates both T cells and B cells are related to mechanism of canine DLE. This case report describes advanced diagnostic tests and clinical outcome with immune suppressive therapy in a rare juvenile canine DLE case.

  • A 3-year-old, 38 kg, male Golden Retriever dog was referred to Veterinary Teaching Hospital of Konkuk University because of chronic formation of crust on nasal bridge and planum nasale. Abnormalities of physical examination included hyperkeratosis on the footpad, symmetrical alopecia and erythma around olecranon, and crust on nasal bridge and planum nasale. Results of the hematological examination showed a mild leukopenia with neutropenia, monocytosis, and mild lymphocytosis. In addition, the result of serum chemistry and thyroid gland profile were normal. Results of fungal and bacterial culture was negative. Acanthocytes in cytological evaluation of nasal crust were observed in direct microscopic examination. Examination of skin biopsy exhibited vacuolation of basal cell layer, degeneration and necrosis of basal cell with defluxion, mild monocytes filtrations between epidermis and dermis, and mild acanthosis with hyperkeratinization. Based on results of examination described above, Discoid Lupus Erythematosus (DLE) was diagnosed.

  • Fluorouracil (FU) is well known to induce discoid lupus-like eruption at the sun exposure sites in Japan. It means the associations of UVB with drug induced DLE. It is still obscure which cytokines are involved in the development of DLE. To address the issue, we established a murine model of FU and UVB-induced discoid lupus and could show the Th1 dominant cytokine profiles in DLE model of TCR $\alpha$ chain KO mice treated with FU and UVB.
