Sebaceous Adenoma

Question: Canine sebaceous adenoma or epidermoid carcinoma? Has anyone had a dog with either of these tumors? If so, can you tell me anything about it? I posted a previous question about tumors. I will be taking him to our vet in the morning, but I have been researching what I think he has. I have ruled out warts because of location and appearance. I am pretty sure he has one of the above mentioned. Any information would be helpful. I know my vet will be able to tell me something tomorrow, but I guess I am stressing about this and would like to talk with someone that has had an animal with either of these. He is an english bulldog. Not sure if this posted correctly?

Answer: Rate of growth is often a good indicator of whether a lump is benign or not. The faster they grow, the more dangerous. I've had a number of growths on various animals over the years. So far, all have been benign; they usually are. I haven't encountered either of the types you mentioned, but I was able to find an entry in my home vet book on one of them: Sebaceous Adenoma "These are common benign tumors found more often in older dogs, particularly Boston terriers and Cocker Spaniels. The average age of dogs with sebaceous adenomas is 9 to 10 years. Sebaceous adenomas arise from oil producing skin glands. They tend to occur on the eyelids and limbs. They may be single or multiple, usually are less than an inch across and appear as smooth, lobulated growths on a narrow base or stem. The surface of the tumor is hairless and occasionally is ulcerated." "Occasionally, a sebaceous adenoma becomes malignant (becoming a sebaceous adencarcinoma). Suspect malignancy if the tumor is larger than one inch, has an ulcerated surface and is growing rapidly."
