Brief Answer:
A sebaceous cyst, might need surgical opinion

Detailed Answer:
Dear XXXX,

Welcome to this site!

This is Dr XXXXXXX XXXXXXX responding to your query. I am a XXXXXXX Consultant Dermatologist.

I have had several patients that present with similar complaints of pimple like bump on the back that has been coming and disappearing of its own. A photo of the rash will be helpful.

This pimple mostly happens due to accumulation of oily secretions in the skin glands which manufacture this oily substance and when they burst the impacted secretions come out. After sometime, there is refilling of these glands and again the same process results.

Generally this process may go on for long periods of time without much discomfort to the individual but sometimes these glands may become too large, or grow rapidly, or get infected, or might look unsightly. Under those conditions, one need to have these removed preferably by a surgeon because the whole of gland including its outer covering needs to be removed in toto.

If there are no symptoms, one can wait and choose a time to visit the surgeon one of the listed symptoms arise.

I hope this helps you in deciding the best course of action for your health.

Our best wishes!
