Fine‐needle aspiration revealed pyogranulomatous inflammation and many ovoid, 2–4 μm diameter, thin–capsulated, basophilic bodies that appeared to be fungal spores or yeast. Results of CBC, serum chemistry panel, lymph node palpation, and radiographs were unremarkable. Excisional biopsy and histopathology revealed pyogranulomatous folliculitis, furunculosis, and perifolliculitis. Rare fungal hyphae and spore forms were intimately associated with, and occasionally within, hair shafts. A morphologic diagnosis of dermatophytosis was made and Microsporum canis infection was confirmed by fungal culture. M canis is a common infectious agent found within the follicles and superficial keratin layers of canine skin. The kerion‐type clinical presentation observed in the dog of this case is uncommonly observed with M canis. Additionally, the cytologic finding of multiple arthroconidia without hyphae is unusual. In the absence of hyphae, M canis arthroconidia may be confused with other fungal yeast bodies; therefore close scrutiny of a cytologic sample for arthroconidia associated with keratin, hair fragments, or hyphal structures is recommended.

Laboratory results included an inflammatory leukogram and a marked increase in plasma uric acid concentration. Synovial fluid from multiple joints was thick, chalky white, and opaque, with a grainy consistency. Microscopically, the fluid contained numerous brown, needle‐like crystals consistent with urates (gout). Gross necropsy findings and histopathology confirmed a diagnosis of systemic gout, with urate deposition, gout tophi, and underlying necrosis in multiple organs, including kidneys, lung, and liver. Dehydration with concurrent renal insufficiency may have impaired urate excretion and led to a build‐up of urates in the blood and tissues of this tortoise. A high protein diet also may have contributed to the development of gout. Cytologic evaluation of synovial fluid can be used as a quick and definitive tool to diagnose gout in tortoises.

Morphologic and cytochemical staining characteristics of erythrocytes, leukocytes, and thrombocyt... more Morphologic and cytochemical staining characteristics of erythrocytes, leukocytes, and thrombocytes of the desert tortoise (Gopherus agassizii) were evaluated, using blood smears prepared from 23 healthy tortoises of Kern County, Calif. Special emphasis was placed on differentiating features of the various leukocytes and thrombocytes. A variety of cytochemical stains, including benzidine peroxidase, Sudan black B, chloroacetate esterase, alpha-naphthyl butyrate esterase, acid phosphatase, leukocyte alkaline phosphatase, periodic acid-Schiff, and toluidine blue were used. Heterophils had a characteristic, large, focal area of positive staining with chloroacetate esterase, alpha-naphthyl butyrate esterase, and acid phosphatase. Eosinophils stained diffusely positive with benzidine peroxidase, allowing differentiation of this leukocyte from heterophils. Thrombocytes stained focally positive with periodic acid-Schiff, allowing differentiation of these cells from lymphocytes, which stained uniformly negative. An intracytoplasmic body, commonly observed within erythrocytes, was considered ultrastructurally to represent a degenerate organelle.
