Myxomatosis skin lesion

Myxomatosis does not only affect the eyelids, nares and genitalia. It can cause circular crusting lesions anywhere on the body. In vaccinated or other rabbits with partial immunity, there may be solitary or multiple lesions that do not seem to worry the rabbit. This lesion is on the ear. Over a course of 4-8 weeks, these 'atypical' myxomatosis lesions will dry out and fall off. The main differential diagnoses are ringworm, a crusting skin tumour such as a melanoma, an injection reaction or an infected bite wound.
