Abstract
- A 12-year-old, spayed female, Maltese dog with a round and firm mass on the dorsal part of the left rear paw and a cervical mass was brought to the clinic. The paw mass was contiguous to the adjacent tendon; it was composed of neoplastic mesenchymal cells and had scattered foci of calcification with chondroid differentiation microscopically. The neoplastic cells were positive for vimentin and S100, but negative for desmin and smooth muscle actin. Microscopic features and immunohistochemistry results were consistent with calcifying aponeurotic fibroma (CAF). The cervical mass was composed of polygonal cells forming acini with marked anisocytosis and anisokaryosis and diagnosed as thyroid follicular carcinoma. No recurrence or metastasis occurred during follow-up. To the best of our knowledge, this is the first case of canine CAF with features identical to its human counterparts. Key clinical message: This report describes the rare case of calcifying aponeurotic fibroma on the paw in a dog. This is apparently the first case in the veterinary literature with identical clinical and pathological features to the human counterpart.<br /> (Copyright and/or publishing rights held by the Canadian Veterinary Medical Association.)
