10 Ganglion Cyst Symptoms
Symptom #7: Nail Anomalies
Digital mucous cysts or ganglion cysts on the digits are usually found on the distal interphalangeal joint and proximal nail fold. They can also occur between the nail plate and proximal nail fold under the nail matrix.
Cysts under the nail plate can result in discolored lunula, causing it to appear red or blue. The transverse curvature of the nail also increases, leading to lateral ingrowth. There can also be the appearance of a longitudinal brownish band. If it involves the posterior nail fold, there can be depression or longitudinal grooving of the nail. The affected nail may also become thinner and have transverse ridging.
