Phalangeal microgeodic syndrome: A case series in five adults

Phalangeal Microgeodic Syndrome (PMS) is rare, characterised by cold related discolouration, pain and swelling of the digits. A handful of case reports exist mainly in a paediatric population in Japan. We describe five cases of PMS. The underlying aetiology remains uncertain, however, a possible correlation with infection or autoimmune dysregulation may suggest a common pathway which is yet to be identified. However, many cases seem to resolve spontaneously.
