Rhabdomyosarcoma in the Canine Maxillofacial Area

Abstract

Two dogs were diagnosed with maxillofacial rhabdomyosarcoma. Management with surgery and chemotherapy showed poor clinical response. The tumour tissues in both cases were observed around upper premolar teeth and CT examination in each case revealed extensive bony involvement of maxilla. Both cases were subjected to surgical excision of the tumour tissue, followed by chemotherapy. The outcomes of treatment of the both cases were poor because of the invasive nature of the tumour cells leading to the local lung metastasis. Both the dogs died within four months. The excised mass was confirmed histopathologically as Rhabdomyosarcoma which is a relatively rare entity.
