Why does a foreign body need to be removed?
The body does not dissolve foreign objects: a capsule is formed around them, and chronic inflammation often develops with periodic suppuration and the formation of a fistula. Organic materials are especially dangerous - wood, plant thorns: they cause a pronounced inflammatory reaction. Before removing deeply located objects, an ultrasound or x-ray is performed for accurate localization; X-ray, however, does not see wood and part of the plastic, so ultrasound is more informative here. Extraction is carried out under local anesthesia with revision of the wound canal and rinsing with an antiseptic.
Removal of benign skin lesions
Lipoma (“wen”), atheroma, hygroma and fibroma are benign formations that do not resolve on their own. While they are small, removal takes 20–30 minutes and leaves minimal scarring.
As the formation grows, the operation becomes more complicated: the incision increases, the risk of suppuration and relapse increases if the capsule is not completely removed. Therefore, postponing intervention is inappropriate.
Why is histology important?
An externally benign formation in rare cases turns out to be malignant. Histological examination of the removed material is a mandatory standard that gives an accurate answer about its nature.
