An 8-year-old, shih-tzu female dog was referred due to neurological signs including paraparesis and back pain. On the complete blood count, hematologic analysis showed elevated leukocytosis. Serum biochemical analysis revealed elevated serum alkaline phosphatase concentration and C-reactive protein concentration. On the neurologic exam, the dog was suspected to have thoracolumbar myelopathy. On magnetic resonance imaging, there were masses within the spinal canal at L1-3 intervertebral disc space that were located dorsal to spinal cord. It was hyperintense on T1-, T2-weighted magnetic resonance images, Fluid-attenuated inversion recovery, and fat suppression images. The contrast-enhanced T1-weighted images showed no enhancement. The lesions were well circumscribed. The spinal cord was compressed and displaced ventrally by the mass. After removal of the masses via L1-L3 dorsal laminectomy, pyogranulomatous inflammation was confirmed by histopathological examination. Six months after surgery, the dog recovered uneventfully and remained fully ambulatory with no neurological deficits. This case demonstrates the utility of magnetic resonance imaging for the diagnosis of spinal canal pyogranulomatous inflammation.

Systemic aspergillosis were outbroken of 17 Korean native calves at livestock farm in Kyunggi province. Two 3 months old calves were died after having diarrhea, coughing, dyspnea, nasal discharge, and abdominal breathing. These calves were diagnosed of aspergillosis as multifocal to coalescing pyogranulomatous inflammation with intralesional aspergillus infiltration at liver, kidney, spleen, heart, lymph nodes, lungs, intestine and cerebrum. Aspergillus fumigatus was cultured from the affected tissues. And the small intestine was positive against bovine viral diarrhea (BVD) virus on FA test. We considered that the secondary fungal infections killed the calves after BVD virus infection primarily.

This study describes a sudden death in an ostrich (Struthio camelus) with a big neck. Grossly, the air sacs were thickened. Yellow to white, round or coalescent material was scattered on the air sacs. However, the cervical air sac was normal. Histopathologically, multinucleated giant cells, heterophils, and macrophages had infiltrated the air sacs, and many hyphae were seen in the air sacs and on their surfaces. Pyogranulomatous inflammation with intralesional hyphae was observed throughout the lungs. Aspergillus fumigatus was identified microbiologically. In conclusion, the affected animal died because of the respiratory disturbance caused by mycotic airsacculitis and pneumonia.

An 8-year-old, castrated male Shih-tzu was referred due to relapsing pododermatitis and generalized pruritus. On physical examination, right forepaw showed swelling and serosanguinous exudates from sinus tract on dorsal paw. There were no remarkable findings on complete blood count (CBC), serum chemistry, and radiologic examination. On cytological examination of exudates from sinus tract, phagocyted bacteria and numerous degenerative neutrophils were noted. Results of deep skin scraping and plucking hair examination were unremarkable. Skin biopsy was performed and ruled out other skin diseases. Histopathology showed epidermal hyperplasia and diffuse mononuclear cell inflammation in dermal layer. Moreover, pyogranulomatous inflammation was demonstrated in subcutaneous layer. This case was clinically diagnosed as pododermatitis secondary to atopic dermatitis (AD). Clinical signs of pododermatitis were gradually improved following topical application of tacrolimus 0.1% ointment. This case report describes that tacrolimus ointment can be applicable for the treatment of refractory pododermatitis.

Multiple enlarged submandibular nodules were discovered during a routine antimortem examination at slaughter in 3 dairy cows of 20-month-old. Grossly, submandibular nodules were firm, reddish, and oval in shape. On cut surface, multiple yellowish abscesses in the parenchyma were observed. Histopathologically, the nodules were characterized by severe diffuse pyogranulomatous inflammation and chronic fibrosis with multiple eosinophilic clubs of Splendore-Hoeppli material containing central bacterial colonies. Trueperella pyogenes was isolated from the lesions. This case was diagnosed as submandibular pyogranuloma caused by Trueperella pyogenes in slaughtered dairy cows in Korea.

Blastomyces dermatitidis is a dimorphic fungus that causes the systemic pyogranulomatous disease known as blastomycosis. Blastomycosis most often involves the lungs, skin, and may involve nearly every organ in the body. It is difficult, however, to diagnose blastomycosis in the early stage of pulmonary disease because clinical manifestations are varied from subclinical infection to acute respiratory distress syndrome. Since blastomycosis is often accompanied by granulomatous inflammation in histopathologic findings, differentiation from other etiologic diseases is important. We report a case of a 45-year-old male with pulmonary blastomycosis who had been misdiagnosed with tuberculosis for 3 months.

A four-year old, indoor-living neutered male Old English Bulldog was presented for generalized ulcerative dermatitis. Generalized alopecia and multifocal papules and ulcers with crusting were observed mainly in the dorsal trunk. Cytology of the skin lesions revealed a pyogranulomatous inflammation comprising macrophages and nondegenerate neutrophils. Histopathology also revealed a nodular dermatitis characterized by mixed infiltration of monocytes and neutrophils involving the superficial and deep dermis. Neither of bacteria nor fungus was identified in microscopic exam and culture. From those findings, a diagnosis of cutaneous sterile pyogranuloma/granuloma syndrome (SPGS) was made. Treatment with immunosuppressive drugs of prednisone and cyclosporine was performed and visible ulcerative skin lesions were resolved after 4 weeks of initiation of therapy. Treatment with combination of cyclosporine and prednisone may be effective for the case of SPGS.

A 12-year-old spayed Pomeranian was presented with a purulent, erythematous mass. The dog also suffered from concurrent hyperadrenocorticism and diabetes mellitus. Sporothrix schenckii was isolated through the fungal culture of the mass. Surgical ablation of the mass was performed for the removal of continuous inflammation and fungal infection of deep origin. After histological examination of the mass, severe multifocal pyogranulomatous dermatitis and panniculitis were diagnosed. This is the first confirmed case of pyogranulomatous dermatitis and panniculitis due to Sporothrix schenckii infection in a dog with concurrent hyperadrenocorticism and diabetes mellitus. In addition this is the first case report of sporotrichosis in South Korea.

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.

An 8 month old leopard gecko (Eublepharis macularius) with a large nodule was referred to our hospital. During the physical examination, the nodule had an unclear boundary from the top of the left eye to the front of the left ear and prevented the opening of the left eye. A hard, cheese-like, yellow, pus-filled nodule was observed. A cytological examination of a pus swab sample revealed pyogranulomatous inflammation with rod-shaped bacteria. Ofloxacin was chosen as the empirical topical antimicrobial drug for treatment. The swab samples were inoculated in trypticase soy agar with 5% sheep blood and incubated at 37℃ for 24 h. Gram-negative bacteria were identified via Gram staining, and the Kirby-Bauer antimicrobial susceptible disk diffusion test against 24 antibiotics according to protocol M100-Ed32 of CLSI showed that the fluoroquinolone group (ciprofloxacin and enrofloxacin) was susceptible to the isolated bacteria. Molecular identification based on 16S ribosomal RNA gene sequencing confirmed that the isolated bacteria had a 99.85% nucleotide similarity with Serratia surfactantfaciens (GenBank accession no. CP014948). After 1 week, the boundaries of the nodule became clear; thus, the abscess was physically removed by expanding the hole formed above the eye for drainage, and flushing was repeated. After another 1 week, new tissue restoration without scarring was observed. This is a rare case report of the successful management of a subcutaneous abscess and scar-free healing in a lizard.
