Thanks for posting your query.
I can understand your concern for the red bumps on your face.
Your concern for adenoma sebaceum is genuine because most of the cases present with tubular sclerosis. However definite tuberous sclerosis is diagnosed by either 2 major features or 1 major feature and 2 minor features and possible tuberous sclerosis is either 1 major feature or 2 minor features. Facial angiofibromas comprises major feature but the reassuring part if multiple skin biopsied which have come negative. Other than that multiple dermatologists’ examination has never raised the suspicion of adenoma sebaceum.
One possibility is of cherry angioma spots also. They are common skin growths containing an abnormal proliferation of blood vessels which can bleed on touch. Cherry angiomas appear spontaneously in many people in middle age but can also, although less common, occur in young people. They can be diagnosed by examination or by skin biopsy.
Discuss these two possibilities with your dermatologist and if you are too apprehensive about the possibility of adenoma sebaceum then you can get a wood’s lamp examination and a comprehensive profile of investigations if there are any associated symptoms like haematuria, abdominal pain, lung symptoms or symptoms pertaining to the cardiac or brain involvement ( seizures, unconsciousness etc).
Hope that this information helps and hope that you get better soon.
Wishing you good health.
