Plain-English summary
A 4-month-old female Finnish Lapphund was taken to the vet for a swelling on her jaw. Tests showed that the swelling was a type of tumor called a plasmacytoma, which can be aggressive. The vet suggested surgery to remove part of her jaw, but before that could happen, the swelling started to shrink on its own. Six months later, the tumor had almost completely disappeared without any treatment.

Abstract
A 4 mo old female Finnish lapphund presented for further investigation of a swelling of the right rostral mandible. A computed tomography scan showed the swelling to be an expansile and osteolytic mandibular lesion. Histopathology revealed a poorly differentiated, moderately well-demarcated, unencapsulated, highly infiltrative round cell neoplasm, and immunohistochemistry was supportive of a plasmacytoma. Performance of a rostral partial mandibulectomy was initially discussed with the owners, but the lesion improved spontaneously both clinically and on repeated computed tomography scanning before surgery could be performed. It subsequently almost completely resolved 6 mo after diagnosis. Hypotheses for spontaneous regression of the lesion are discussed and the human literature is briefly reviewed.
