Leiomyomas in Dogs and Cats
Leiomyomas are benign smooth-muscle tumors that can arise wherever smooth muscle exists, such as the uterus, stomach, intestine, and blood-vessel walls. Dogs are affected more often than cats. Surgical removal is the usual treatment, and follow-up care prevents spread.
Myomas (Rhabdomyomas and Leiomyomas) in Dogs and Cats
Myomas are muscle tumors that include rhabdomyomas and leiomyomas and may be benign or malignant. In dogs the malignant rhabdomyosarcoma is most often seen, with an unclear cause that may be hereditary. They can occur in any muscle-containing organ and are hard to remove once invasive.
Multiple Myeloma in Dogs and Cats
Multiple myeloma is a malignant plasma-cell tumor of the bone marrow that overproduces immunoglobulin and is rare in dogs and cats. Signs include lameness, bone pain, anemia, bleeding, and weakness, with diagnosis by X-rays, bloodwork, and marrow sampling. Treatment is chemotherapy plus infection control.
Chondrosarcomas in Dogs and Cats
Chondrosarcoma is a malignant bone tumor from cartilage cells, second only to osteosarcoma in frequency. It favors flat bones such as ribs, nasal bones, and pelvis and is seen more in German Shepherds. Outlook is guarded even with surgery.
Osteosarcomas in Dogs and Cats
Osteosarcoma is a malignant bone tumor from abnormal osteoblasts, most common in large and giant dog breeds. The main sign is lameness, with swelling, pain, and possible pathological fracture. Early limb amputation plus anti-cancer medication is standard, but the outlook is poor.
Osteomas in Dogs and Cats
Osteomas are common benign bone tumors formed from bone tissue, often linked to exostoses, injury, bone inflammation, or nutritional disorders. They usually cause no signs unless they press on a nerve or organ. Surgery is used when the site allows, and amputation for malignant limb tumors.
Mammary Tumors in Dogs and Cats
Mammary tumors are common in intact female dogs and are the third most common feline tumor. They often appear as firm nodules in the mammary chain and can ulcerate or spread to lymph nodes and lungs. Early spaying sharply lowers risk, and surgery is the main treatment.
Cutaneous Fibromas in Dogs and Cats
Cutaneous fibromas are benign tumors that arise spontaneously or after injury and can occur anywhere on the skin of dogs and cats. They are well-defined, hairless, and rarely ulcerate, and small ones may need no treatment. Surgical removal cures most cases.
Cutaneous Mast Cell Tumors in Dogs and Cats
Cutaneous mast cell tumors can appear anywhere on the skin or internal organs, most often on the hind legs, perineum, and prepuce. They vary from slow soft lumps to fast hard nodules and may ulcerate. Surgical removal of well-defined tumors is the main treatment.
Fibrosarcomas in Dogs and Cats
Fibrosarcoma is a malignant tumor of fibrous tissue and the second most common mouth tumor in dogs. About 60 percent arise in the skull bones and 30 percent in the long bones. It is firm, invasive, and bleeds easily when sampled. Surgery is the main treatment.
