MACROPODS

Macropods are moderately susceptible to neoplasia. Of 179 cases in the literature and ARWH (2018), 141 were malignant (78.8%) (Tables 18.8 and 18.9). Neoplasms recorded more than once in a single species include mammary adenocarci­noma and carcinoma in red kangaroos (n = 15) and parma wallabies (Notamacropus parma) (n = 3), oral SCC in red kangaroos (n = 2), SC lipoma in red kangaroos (n =2) and cutaneous carcinoma-in-situ in swamp wallabies (n = 2). Superficial neoplasms may be over represented because of ease of detection. Mammary neoplasia is relatively common (n = 27), of which 96% were malignant. Cutaneous and SC neoplasms are also relatively common. Principles of treat­ment are discussed in more detail in sections 1.1 and 1.2.
