An abnormally enlarged right ovary and a mass in fat surrounding the right kidney were discovered in a dairy cow during routine postmortem examination at slaughter. The ovary was dark reddish and multinodular in shape. Numerous cystic structures were identified in the mass. Histopathologically, the ovary was completely replaced with large, uniform, polyhedral neoplastic cells containing vesicular nuclei and prominent nucleoli. The mitotic index was high. In the lymphatic vessels, tumor emboli were observed. Another mass in the fat surranding the right kidney had the same histological features as the ovarian mass. This animal was diagnosed with malignant dysgerminoma and metastasis to other peritoneal organs.

Four 3-day-old piglets with retarded growth were submitted to the Animal and Plant Quarantine Agency for diagnosis. Necropsy showed that one piglet had black spots ranging from 2 mm to 1 cm in diameter in the cerebellum, lungs, regional lymph nodes, and cecum. Histological findings were consistent with the gross appearance in which melanin pigmentation was observed in the organs mentioned above. Based on Fontana-Masson staining, we diagnosed this animal with systemic melanosis. To the best of our knowledge, this is the first case of systemic melanosis in black breeds of swine in Korea.

In this study, we describe a case of epitheliogenesis imperfecta (EI) observed in the fetus of Korean native cattle. The fetus had multifocal areas of skin defect, especially on the distal portions of the four limbs, and the affected areas were bright-red and glistening. Histopathologically, these areas were characterized by complete absence of squamous epithelium, infiltration of inflammatory cells into the dermis, atrophy of hair follicles, sebaceous and sweat glands. To the best of our knowledge, this is the first report of epitheliogenesis imperfecta in Korean native cattle.

Two Korean black goat (approx. 2 and 3 years old) showing diarrhea and chronic weight loss were submitted to Animal and Plant Quarantine Agency. At necropsy, there were thickening of small intestine and enlargement of mesenteric lymph nodes. Microscopically, they had granulomatous enteritis in the small and large intestine and granulomatous lymphadenitis. By polymerase chain reaction (PCR) and acid fast stain, strong positive reaction and acid-fast rod bacteria were detected. According to the result of histopathology and PCR, we confirmed this case as Johne's disease. As far as we know, this is the first report of Johne's disease in Korean black goat.

Porcine ear necrosis syndrome is characterized by erosive and ulcerative lesions at the margin or tip of the pinna. Three growing pigs of different ages exhibited retarded growth accompanied by reddening and necrosis of ear prior to death. Gross examination showed reddening, swelling, black discoloration, scaling, and variable-sized yellowish materials and edema in ear cross section. Microscopically, thrombosis, abscess, ulceration, epidermal hyperplasia, and dermal pyogranulomatous inflammation with an intralesional bacterial colony were observed. Staphylococcus hyicus was isolated in all pigs' ears and porcine reproductive and respiratory syndrome virus was detected by PCR and immunohistochemistry.

A calf suffering from diarrhea was admitted to the Animal and Plant Quarantine Agency for diagnostic evaluation. Postmortem examination revealed that the mesenteric lymph node was enlarged and small intestine wall was thin. Microscopically, a large number of small round organisms were attached to the small intestine villi. Villous atrophy and proprial neutrophil infiltration were also observed. Based on modified Ziehl-Neelsen staining, electron microscopy, and ELISA results, the calf was diagnosed with fatal cryptosporidiosis.
