Plain-English summary
A young male Bernese Mountain Dog was brought to the vet because he was limping and had swelling in his right back leg. Imaging tests showed several abnormal growths in the muscles of his thigh. A biopsy revealed that these growths were made mostly of collagen fibers and benign cells, leading to a diagnosis of fibromatosis, a type of soft tissue tumor. While this condition is rare in young dogs, it was likely a form called infantile fibromatosis. The dog will need ongoing monitoring and possibly treatment, depending on how the condition progresses.

Abstract
A young, intact, male Bernese Mountain Dog was presented to the animal hospital for lameness and diffuse thickening of the soft tissue in the right hind limb. Magnetic resonance imaging revealed multiple, multilobular, space-occupying lesions within and between the muscles of the right femur. Biopsies taken from the lesions revealed an infiltrative mass composed mainly of collagen fibers and a low density of benign-appearing fibroblasts. These findings were compatible with a diagnosis of a fibromatosis. Taking the age of onset into account, infantile fibromatosis was most likely. A deep fibromatosis, similar to that seen in adults, could not be excluded based on histology.
