An unusual case of diabetes

Finding an elevated HbA1c in an older female patient with a complicated medical history leads a GP to make an unexpected diagnosis.

When her usual GP is on leave, 67-year-old Jen presents to a GP she has not seen previously with early cellulitis affecting her forearm, after a day of heavy pruning and mulching in the garden. 

A retired nurse, Jen has a complex medical history, including breast cancer treatment in 2008. Post-chemotherapy, she developed chronic neutropenia and cardiomyopathy, and in 2017 she needed percutaneous coronary intervention.
