Anaplastic Sarcoma and Sertoli Cell Tumor in a Central Bearded Dragon (Pogona vitticeps).

A five-year-old male central bearded dragon (Pogona vitticeps) was presented for investigation of blood in the voided urates. A small cutaneous mass was detected in the gular region, but clinical examination was otherwise unremarkable. Fecal parasitology was negative. Initially, further diagnostics were declined, and antimicrobial treatment was initiated. At re-examination one month later, the gular mass had increased in size and an additional mass was detected within the celomic cavity. Both masses were surgically excised and diagnosed by histopathology as a high-grade anaplastic sarcoma (gular mass), resembling a histiocytic sarcoma, and a Sertoli cell tumor (coelomic mass). Neither of these have been previously reported in the central bearded dragon. Twenty months post-surgery, the lizard remains well with no recurrence of clinical signs or evidence of tumor re-growth.
