Canine calcinosis circumscripta - retrospective studies
This is a study of 18 cases of canine calcinosis circumscripta (CC). The objective of the research was to present the CC cases recognized in ten years in veterinary clinics in Lublin. The following factors were analyzed: dog age, breed and sex, the anatomical location of calcium salt deposits in each dog, a potential cause of the disorder and the incidence of its remission after surgical treatment. The age of the dogs in the study varied from 6 months to 1 year (11 cases). Seven dogs were more than 2 years old. The dogs belonged to different breeds of both sexes, German Shepherd Dog prevailed (10 cases). The lesions occurred within limb joints (16 cases) and the ventral area of the tongue (2 cases). General clinic signs such as elevated body temperature and apathy were presented in one animal. In five cases local inflammation was observed. In three cases where tissue damage appeared in the affected region there occurred slight bleeding and exudates. None of the dogs had similar symptoms in the case history and none of them had surgical procedures performed in the affected region earlier. Only in one dog calcinosis circumscripta was not the only disease which occurred in that animal. In three cases lesions in the limb region occurred due to apparent physical damages. In the other cases no single cause was established. In eight cases radiographic evaluation was performed. In twelve cases the diagnosis relied on the histopathological examination of the surgically excised lesion; in one case fine needle aspiration cytology was employed. After surgery the recurrence of the disease was reported in three cases.
