RESUMEN
Disseminated candidiasis is an opportunistic infection in immunosuppressed animals by Candida species. The purposes of this study were to determine the predominant candidal forms in different tissues and tissue reactions. Sixteen dogs were selected in this study. The treatment dogs were immunosuppressed by intravenous administration of cyclophosphamide and after 5 days, they were challenged with 1 _ 10[5] blastospores of C. albicans by intravenous injection. Both mycological and histopathological examinations were performed for detection of Candida in various tissues. The results showed that the highest counts of C. albicans were recovered from the lungs, followed by the kidneys, heart and liver on day 2 after challenge. The presence of yeast mixed with hyphal forms of C. albicans was confirmed in all tissues. In most tissues, the yeast cells of Candida were predominant, whereas hyphal forms, particularly true hyphae, were mostly found in the brain and eyes
RESUMEN
Diagnosis of a subcutaneous mass in a rabbit. Case report. A 3-years-old female mixed shorthair black and white rabbit. The rabbit was referred to the Small Animal Clinic, Faculty of Veterinary Medicine, University of Tehran, with a 1-month history of a cutaneous mass. Clinical examinations, radiography of thorax and ultrasonography of abdominal cavity was carried out. The mass was removed surgically. Clinical examinations revealed a well circumscribed subcutaneous mass on left gluteal region. Macroscopically the mass was solid, ovoid [1.6x1.3 x 0.6 cm] with reddish cut surface and flesh-like consistency. Histopathologic examination revealed prominent, oval, basophilic nuclei, with single scant nucleolus and eosinophilic cytoplasm. The tumor cells morphologically resembled the normal basal cells of the epidermis and showed no epidermal or adenexal differentiation. This is the firstreport of rabbit trichoblastoma from Iran, [basal cell tumor]
RESUMEN
Objectives: clinical case report of leydig cell tumor in dog
Design: clinical case study
History: an eleven year old male German shepherd dog was reffered, small animal hospital of faculty of veterinary medicine because of Anorexia. Because of poor body condition, the animal was euthanised and submitted for necropsy examination. Based on the light and electronic microscopic observation, leydig cell tumor was confirmed
Clinical implications: occurrence of tumor in dog is without clinical findings, therefore maybe testicles are not necroptize at necropsy. Thus the rate of tumor, must probably be higher than it is reported
Results: histopathology and uttrastructural observations, confirmed the leydig cell tumor
