Hi, thanks for writing to HCM and sharing your son's health problem...
After going through your description, if I were his treating Doctor for this case of growing head lump, I would come up with three possibilities, these include:
1. a
dermoid cyst or any other
benign cyst like sebaceous cyst
2. The second possibility is of benign and simple conditions like
lipoma or
neurofibroma or fibroma/dermatofibroma; there is nothing to worry about these!
3. The last possibility is of some lymph node or a skin polyp! Nothing to worry about these also!
Overall, it is benign but prone to get infected any time; therefore better to remove it...
Well, I suggest you to go for an FNAC/
biopsy 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 your son good health.
