Hi, thanks for sharing your health concerns with Chat Doctor!  If I were your treating Doctor for this case of butt-crack lump, I would come up with only one and one possibility that is a sebaceous cyst! Nothing to worry about this and try not to get infected there! However, it could be some benign tumor like neurofibroma or lipoma like conditions also! I suggest you to go for an FNAC test of the lump for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
