Osteoma cutis refers to heterotropic ossification within the skin. Whilst veterinary reports are few, a number of cases suggest an association of osteoma cutis in dogs with chronic glucocorticoid therapy. Steroid Responsive Meningitis Arteritis (SRMA) is an immune mediated inflammatory disorder of the leptomeninges and associated arteries. It is typically seen in young dogs between 6 and 18 months. Patients commonly present with cervical pain and pyrexia. Prednisolone monotherapy is the mainstay of treatment. We report a case of osteoma cutis in a dog with a concurrent relapse of SRMA. We also report the use of cytarabine as a successful treatment for the SRMA.
