Summary
Pheochromocytoma is a rare tumor of the adrenal gland. It often presents with the classic triad of headache, palpitations and generalized sweating. Although not described as a typical symptom of pheochromocytoma, anxiety is the fourth most common symptom reported by patients suffering of pheochromocytoma. We report the case of a 64 year old man who had severe anxiety and panic disorder as presenting symptoms of pheochromocytoma. After 13 years of psychiatric follow-up, the patient was diagnosed with malignant pheochromocytoma. After surgical resection of his pheochromocytoma and his hepatic metastases, the major panic attacks completely disappeared, the anxiety symptoms improved significantly and the psychiatric medications were stopped except for a very low maintenance dose of venlafaxine. We found in our cohort of 160 patients with pheochromocytoma 2 others cases of apparently benign tumors with severe anxiety that resolved after pheochromocytoma resection. These cases highlight that pheochromocytoma should be included in the differential diagnosis of refractory anxiety disorder.
Learning points:
-
Anxiety and panic disorder may be the main presenting symptoms of pheochromocytoma.
-
The diagnosis of pheochromocytoma should be excluded in cases of long-term panic disorder refractory to medications since the anxiety may be secondary to a catecholamine-secreting tumor.
-
Surgical treatment of pheochromocytoma leads to significant improvement of anxiety disorders.

Summary
In daily practice, clinicians are often confronted with obese type 2 diabetes mellitus (T2DM) patients for whom the treatment plan fails and who show an inadequate glycemic control and/or no sustainable weight loss. Untreated hypogonadism can be the reason for such treatment failure. This case describes the profound impact testosterone therapy can have on a male hypogonadal patient with metabolic syndrome, resulting in a substantial and sustained loss of body weight, pronounced improvement of all critical laboratory values and finally complete remission of diabetes.
Learning points:
-
Hypogonadism occurs frequently in men with T2DM.
-
In case of pronounced abdominal fat deposition and T2DM, the male patient should be evaluated for testosterone deficiency.
-
Untreated hypogonadism can complicate the successful treatment of patients with T2DM.
-
Under testosterone therapy, critical laboratory values are facilitated to return back to normal ranges and even complete remission of diabetes can be achieved.
