Hapalonychia, is a condition in which a toenail or fingernail (or multiple nails) nail becomes soft and thin, causing it to easily bend or break.[1] This can result from an inherited condition, [1]

It has been associated with low dietary calcium.[2] Hapalonychia is known to occur in persons suffering from myxedema, rheumatoid arthritis, anorexia, bulimia, Hansen's disease, Raynaud phenomenon, oral retinoid therapy, and radiodermatitis.
