what is basal cell hyperplasia of esophagus

What is basal cell hyperplasia of the esophagus?  How is it treated?  This is re:  a child who can't tolerate gluten but has never had an EGD so has no diagnoses. Only had esophagoscopy showing basal cell hyperplasia proximal & distal.  Thanks!

Basal cell hyperplasia is the increase in the number of cells in an epithelium (the covering of internal and external surfaces of the body) resembling the basal cells (small, round cells found in the lower part, or base, of the epidermis, the outer layer of the skin.)

So, basically, there's a lump in your throat. Whether it's benign or not would probably require a biopsy to tell.
