Malignant Neuroendocrine Tumour (Carcinoid) of the Spleen in an African Pygmy Hedgehog (Atelerix albiventris).

A malignant neuroendocrine tumour (carcinoid) of the spleen was diagnosed on post-mortem examination of a 3-year-old, male African pygmy hedgehog (Atelerix albiventris). The animal presented with a history of inappetence, weight loss, lethargy, a wide-based gait and a palpable abdominal mass. The gross pathological, histopathological, histochemical and immunohistochemical findings are described. Primary splenic carcinoids are reported rarely in the human medical literature and this is believed to be the first report in a non-human animal.
