[Chronic musculoskeletal pain syndrome in primary hyperparathyroidism].

Chronic somatic pain disorders with somatic and mental factors (ICD-10: F45.41) are common among psychosomatic patients. In the present case, due to the close temporal association with a trauma and the subsequent development of symptoms including depressive symptoms, a chronic pain disorder with a relevant somatoform component was suspected. However, after a period of several months without significant somatic findings, targeted diagnostic approaches resulted in the diagnoses of primary hyperparathyroidism and a papillary thyroid carcinoma. Surgical therapy resulted in an almost complete decline of symptoms within a short period of time.
