Idiopathic conditions, such as inflammatory pseudotumor, Kimura's disease, and Castleman's disease, can also present with a neck mass.22 â 24 A neck mass may also be the presenting symptom of sarcoidosis.25
Many people with sarcoidosis don't have type 1 diabetes as well, so it is unlikely that sarcoidosis caused it all alone. Most people who are going to manifest type 1 diabetes are diagnosed in childhood or their teenage years. Occasionally it will not manifest until adulthood.
Because sarcoidosis can cause many unrelated symptoms over a period of years, it can be puzzling for doctors and difficult to diagnose. The doctor will ask you to have investigations which may include tests of blood, urine, breathing, chest x-ray, electrocardiograph (ECG), neurological and eye examinations.
