Single Digit Leuconycia
The patient is a 64 yo school teacher who presents for a white nail.
Anamnesis: "The nail has been white for at least 6 months. No other fingernails or toenails are white. I had a ring on that finger that got super tight. I have finally removed the ring. Sometimes the finger hurts, even now, like it may be arthritic."
O/E: The nail of the 4th finger of the left hand is uniformly white. There is no flaking or friability. Other than the color, the nail plate looks normal. All other finger- and toenails are normal
Diagnosis: Singe Digit Leuconycia. This does not look like superficial white onycholysis. At the time I saw the patient, I did not think to do a KOK prep since the nail plate looked so normal. In retrospect, I think this should be done.
The patient's questions are:
Is there something I can do to get it back to being a normal color?
Will it ever go back on its own to being normal - no longer white?
