Canine Cutaneous Lymphoma

Cutaneous lymphoma is another round cell tumor of dogs.

While lymphoma is a common cancer in dogs, the cutaneous form is actually quite rare, accounting for only about five percent of all canine lymphoma cases.

Two forms of canine cutaneous lymphoma exist: epitheliotropic and nonepitheliotropic. In humans the epitheliotropic form is also called mycosis fungoides because of the mushroom appearance of the lesions in people.

In dogs, however, the cancer is more likely to appear as one or more areas of widespread inflammation. Typically, multiple areas of skin are involved. Because the common age of onset of cutaneous lymphoma in dogs is five to eleven years, these patients may have had a history of chronic skin lesions in the past.

Common locations include the junction of mucus membranes and skin, so the mouth, eyes, rectum, vulva and prepuce may be affected.

Metastasis to nearby lymph nodes frequently occurs, so lumps in those areas are often associated with this disease. Systemic disease signs may be present if other organs, such as the liver, kidneys or spleen have been seeded by tumor cells

In cats, the nonepitheliotropic form of cutaneous lymphoma is the more common, but this form is even more rare in dogs. One or more lesions may appear, and patients find them to be very itchy.

Treatment is mainly palliative due to the extremely poor prognosis of this disease. Single lesions may respond to radiation, and chemotherapy may buy time for the patient, although resistance to multiple chemotherapeutic agents is common.

    Dear Dr. Randolph, Thank you for your reply to my email and for your caring. Jacob’s oncologist is Steven J. Susaneck in Houston, Texas. I hope that these pictures will help someone who goes to your Web site looking for information on eptheliotropic cutaneous lymphoma. I fear that Jacob has almost come to the end of his battle with lymphoma and with Cushings disease before that. He has been a brave little man and continues to be now. I pray that I will know what to do that is right for Jacob, as I always told him every time we would get in the car to go to the Dr. he would start shaking and I have always told him “Don’t worry, Jacob, I’m not going to let anything happen to you.” I only hope that I can keep my promise to him. Thank you and your wife for your prayers for Jacob. Estelle Nelson and Jacob diagnosed with cutaneous lymphoma July 25 2012 and Cushings disease May 2011

    Dear Dr. Randolph, I last received a message from you at the end of August after I had written to you for information about cutaneous lymphoma as my dog Jacob was diagnosed in July. Jacob has been receiving chemo since August and some of them did cause his skin tumors to dry up but at Jacob’s last appointment this past week his oncologist told me he did not think there was anything else to try. However, he did suggest Masitinib used for mast cell tumors. We are trying that for 3 weeks. Your last email to me was very touching when you mentioned Jacob’s namesake in the Bible and that is why I named Jacob, after Jacob in the Bible. He is still hanging on and continues to eat well but it is obvious that the disease is progressing and he has lost almost all of his beautiful golden hair and now has some lesions on his face and head. I just wanted to let you know how Jacob was doing and ask you to continue to pray for him. Estelle Nelson and Jacob diagnosed with epitheliotropic cutaneous lymphoma, July 25 2012.

      Estelle, my wife and I would be honored to continue to pray for Jacob. Please continue to send updates, as we and many readers will also want to know about the progression of his condition. Thank you for loving Jacob enough to do everything possible for him.

    I did start my dog Jacob on chemo on August 2 with an oncologist here in Houston. He was started on Prednisone 20 mg. a day. At first the tumors started drying up quickly, but by the second week they were starting to come back. I continued with the chemo, he has just finished a 4 day regimen of oral Cytoxan. The skin lesions have come back and are now covering most of his body except his head and face. We go back tomorrow so I don’t know what will come next. He continues to have a good appetite and seems still to have energy. I would appreciate if you would include Jacob in your prayers. Thank you Estelle and Jacob

      Your comment has touched and broken my heart. My wife and I lost two pets (Pearl and Martha) in 2011 and it still hurts. To think of what must ultimately happen when a dog has cutaneous lymphoma (the most difficult form to treat) means that sweet Jacob will not be with us much longer. Fortunately, in cases where one chemotherapy drug doesn’t work, another one might. So, your Houston oncologist may be able to buy you some additional time with Jacob. When I got your message I stopped what I was doing and my wife and I prayed right then for Jacob and for you. Please keep us posted on Jacob’s progress. His namesake, Jacob of Biblical fame, so greatly loved his Rachel and I know that your Jacob has given you all of the love he has. What a great blessing our pets are, a gift from God.

    I came across your site while trying to find information on lymphosarcoma after my 13 year old Cocker-mix was diagnosed this week. He has the cutaneous form with involvement in the lymph nodes. Within 3-4 weeks he went from having diffuse rashes and a few open areas to losing all hair except on the head and face and enlarged lymph nodes behind the knees and large plaques that are now beginning to involve the sheath of the penis. I am unable to afford conventional chemotherapy, radiation or other treatments as he also has Cushing’s for about a year and a half which was being treated with Trilostane which has now been discontinued. I am desperate for information as to how I might be able to not cure but maybe slow down the progression or at least alleviate some of his skin discomfort. I am in Houston TX and he has been receiving treatment for his Cushings at Tanglewilde Veterinary Clinic. Are any of the holistic treatments such as the Budwig diet, Essiac tea, turmeric, etc. effective at all for palliation? I would appreciate any information you could give me. Thank you, Estelle Nelson.

      I’m sorry I’m not familiar with any of the holistic treatments you mention. Perhaps your local doctor could help, but I’m only assuming that you’ve asked. Unfortunately, the cutaneous form of lymphoma frequently has the poorest prognosis, and that is made even poorer when treatment isn’t in the picture. I’m also assuming here, but is he on oral and/or injectable forms of corticosteroids, or is the level already high from his now-untreated Cushing’s Disease? I’d be happy to help if there are any questions I can answer for you. I’m sorry you’re having to face such a bleak picture. Send me your dog’s name and we will keep him and you in our prayers.
