Abstract

We are very interested in the article by Sarman et al.1 A rare
cause of shoulder pain: Ganglion cyst of the acromioclavicular
joint.1 Ganglion cyst often induces severe pain and impairs
quality of life, even with multi-modal therapies. The ganglion cyst
commonly develops along the tendons or joints. Ganglion cysts
are typically round or oval shape and filled with a jellylike fluid. We
appreciated the rare case report by Sarman et al.1 Sarman et al1 performed
an image investigation to clarify the tissue content by an Xray
and an magnetic resonance imaging (MRI) examination. They
found a 10×8×5 cm mass which was homogenous fluid contained
with a septum. And the lesion had several cysts in the T2 image.
Although, it looked like a benign lesion as the author described, a
painful mass raised the alarm. The possibility of malignant change
is because of the lesion size which is bigger than 5 cm as well as a
deep mass or one adhering to the fascia.2 Conversely, a mass that
moves with the muscle tissues is probably superficial and less likely
to be malignant.
