Idiopathic Hyperhidrosis after Trauma: A Case Report

Background Hyperhidrosis is the secretion of excess sweat beyond what the body needs for homeostatic regulation. Secondary hyperhidrosis is usually related to an underlying cause, mostly a medical condition, or extrinsic factors such as drugs or trauma to the central nervous system. Treatment can be based on resolution of the underlying cause or symptomatic management. Case presentation A 53-year-old male collided with a motor-vehicle at 40 km/h. Lacerations on his forehead and multiple abrasions on his lower extremities were treated shortly; however, the patient soon started complaining of excessive sweating. Despite several imaging and laboratory tests for central and peripheral causes, we failed to identify the reason for excessive sweating. Symptomatic treatments such as anticholinergics and ganglion block also failed, and only after hemodialysis did the patient stay dry for a short time. Fortunately, his symptoms disappeared shortly after discharge. Conclusion The patient presented with great discomfort after trauma, with an undisclosed cause. Medical treatment and intervention failed to improve the symptoms; however, hemodialysis alone relieved the patient. Whether it was medically or traumatically induced, uncontrolled sweating was controlled by hemodialysis.
