A retrospective study of disease incidence in African pygmy hedgehogs (Atelerix albiventris)

[摘要] The African pygmy hedgehog (Atelerix albiventris) is becoming a popular pet in Japan. The aim of this study was to determine the incidence of various diseases in African pygmy hedgehogs. We histologically investigated 105 samples from 100 privately-owned pet African pygmy hedgehogs that were submitted to two laboratories (North Lab and Patho Labo) between 2012 and 2017. Tissues submitted for this study were taken from female reproductive organs (33 cases; 31.43%), skin (20 cases; 19.05%), and the oral mucosa (19 cases; 18.1%). The most common histological diagnoses included endometrial stromal nodules identified as benign uterine neoplasia (14 cases; 13.33%); endometrial polyps identified as non-neoplastic polyps (7 cases; 6.67%), gingival hyperplasia and chronic suppurative inflammation in the oral mucosa (11 cases; 10.48%), fibrosarcomas in the skin (8 cases; 7.62%), and mammary tumors (8 cases; 7.62%). In this study, lymphoma and oral squamous cell carcinoma were less common than in the previous reports. The present study revealed the disease prevalence in captive African pygmy hedghogs that were histopathologically examined.
