The aim of this study was to assess the clinical and aetiological aspects of contact dermatitis of the scrotum in dogs.
The medical records of 13 dogs with suspected scrotal contact dermatitis were retrospectively included in the study. For each case, historical findings, results of physical and dermatological examination and of avoidance tests as well as follow-up were included. Results of re-exposure tests and patch tests were also included when available.
Avoidance tests to various suspected substances such as floor detergents, bleach, cement, laundry detergent and plastic fabric were performed and led to clinical improvement in all patients. Provocative re-exposure was performed in six cases, with five positive responses. Patch tests were undertaken in three of the five re-exposed cases, with two responding positively.
Scrotal skin is thin and with few hair follicles, and is therefore very susceptible to contact dermatitis. A range of substances can induce contact dermatitis. The diagnosis of contact dermatitis is made by results of avoidance and/or provocation tests and/or patch tests. Once an aetiological agent has been identified, treatment is straightforward consisting of avoidance of this agent.
本研究旨在评估犬阴囊接触性皮炎的临床和病因学方面。
回顾性纳入13例疑似阴囊接触性皮炎犬的病历。对于每例病例，纳入病史、体格检查和皮肤科检查结果、回避试验结果以及随访情况。如有再暴露试验和斑贴试验结果也一并纳入。
对各种疑似物质如地板清洁剂、漂白剂、水泥、洗衣粉和塑料织物进行了回避试验，所有患者的临床症状均有改善。6例进行了激发性再暴露试验，5例呈阳性反应。在5例再暴露病例中的3例进行了斑贴试验，2例呈阳性反应。
阴囊皮肤薄且毛囊少，因此极易发生接触性皮炎。多种物质可诱发接触性皮炎。接触性皮炎的诊断依据回避和/或激发试验和/或斑贴试验结果。一旦确定病因，治疗很简单，即避免接触该病因。
