A 64 year old lady presented with pain and swelling at the tip of her right index finger. She works as a seamstress. An x-ray was done. What do you think?
The x-ray showed a cystic lesion at the distal phalange of her index finger.
This is consistent with intraosseous epidermoid cyst.
The cause is said to be implantation of the epidermis into the bone. In her case, being a seamstress, she could have poke a needle deep into her finger.
These are benign lesions and a form of pseudotumors (not real tumours).
The condition can be easily treated by curettage.
