hi
Your husband seems to have developed a
hypertrophic scar or keloid as the site of surgery...These lesions occur due to overgrowth of fibrous tissue at any site of injury/ surgery .Such lesions are mostly seen over upper back and chest...There are certain people who are predisposed to develop hypertrophy during the process of
wound healing...It is important to find out if your husband had a similar tendency earlier also,,ie development of a hypertrophic scar at any site of trauma
My advice is the lesion needs proper assessment by a
dermatologist,,,
In the mean time , you can apply a steroid cream like
Clobetasol over the lesion twice a day,,If it doesnt settle, then sometimes intralesional
steroids are needed to improve the raised lesion..
Hope it helps
