Primary Pyomyositis of the Adductor and Pectineus Muscle in Patients With Uncontrolled Diabetes: Report of Two Cases.

Muscle amyotrophy and infarction are known to be rare complications of patients with diabetes mellitus and poor glycemic control. However, primary pyomyositis, an especially rare infection of the primary muscles, is also a problem that cannot be ignored. Primary pyomyositis typically begins as a subacute condition and is probably due to transient bacteremia. Here, we report on two patients with Type 2 diabetes mellitus and poor glycemic control who developed primary pyomyositis, which manifested as abscesses of the adductor and pectineus muscles. Both patients underwent surgical drainage, and one patient additionally underwent internal fixation while receiving a continuous local antibiotic perfusion. Both patients were well and without signs of recurrence at their final follow-up visit. Primary pyomyositis, in addition to muscle amyotrophy and infarction, should be included in the differential diagnosis of infections occurring in patients with painful lesions in the lower extremities and Type 2 diabetes mellitus with poorly controlled glycemia.
