Hello, Brief answer: Mostly, a wart needs to be checked as it is growing, ischemic colitis symptoms include acute abdominal pain, diarrhea or blood in stool. Explanation: My opinion is that your finger lesion description is a bit of concern, as growing mass with color variation you said. A wart is a provisional diagnosis but that mass need to be checked. Ischemic colitis presents to us as acute sharp abdominal pain with eating we call it angina of abdominal, some cases may develop diarrhea plus or minus bloody stool. I suggest my patients the following: Do not scratch that mass, if a wart it may spread to other sites. The information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition I would ask them about type of operations you made as ischemic colitis patient, also level of diabetes and other risk factors control. Conclusion: I suggest you check with your general physician to examine your hands, also continue on your medicines and if any symptoms I mentioned above develop, check in ER. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Mahmmad Gamal
