What causes a lump in the crease of an elbow in a child?
Patient: My daughter has had a lump in the crease of her elbow for some time.  She is 2 1/2.  It started very small, like a pimple or blackhead and grew to a hard lump the size of like a chick pea.  It doesn't bother her unless it is pressed on.  Had a regular check up the other day, pointed it out and had an ultrasound on it today.  It is not fluid filled...it is tissue and had blood flow.  Dr is recommending MRI.  What are the options of what it could be? Doctor: Hi....it could be a lipoma or subcutaneous collection of fat which is hardened or other possibility is that it could be a dermoid though unlikely... It could just be a collection of fibrous tissue too.MRI would definitely help in delineating the lesion well anatomically but, a confirmed diagnosis can be got only after a biopsy or excision and histopathological examination.Regards - Dr. Sumanth
