Dr. Bermant: I have a question to ask you: what is most likely in a 14-year-old boy with unilateral tender gynecomastia? thanks!
Tenderness is a common Symptom of Gynecomastia
most often from the stimulation of tissues by hormones.
The most likely issue for a 14 year old's cause of gynecomastia either unilateral, uneven, or bilateral will all be the hormonal imbalance of puberty. A clinical exam by an experienced Gynecomastia Surgeon is the next best step. Breast cancer can also be one sided but tends to have certain characteristics.
Yes, I have seen many men who had gynecomastia only on one side. True One Sided or Unilateral Gynecomastia
is the ultimate test of a doctor's skill. Make an operated side match something that never had surgery! Here is another example of One Sided Gynecomastia
. For most, the real problem is Assymetric or Uneven Gynecomastia, one side larger than the other
Hope this helps,
