PHOTOTOXIC REACTION AFTER PARATHYROID SURGERY: CASE REPORT AND REVIEW OF THE LITERATURE

AbstractBackground: A woman of 41 years old underwent surgery for primary hyperparathyroidism. She developed a long-lasting sharply demarcated erythematous skin reaction, appearing one hour after parathyroid surgery. This erythematous reaction felt like sunburn and was limited to the light exposed skin of the operation field, leading to the diagnosis of a phototoxic reaction. Since this phototoxic reaction occurred just after changing the operation lamp from a halogen type to a Light-Emitting Diode (LED) type, we suspected that the type of operation lamp could be a part of the cause of this phototoxic reaction. This is because our department has never before diagnosed phototoxic reactions (with a halogen type of operation lamp) during methylene blue (MB) assisted parathyroid surgery.Methods: To investigate the cause of this phototoxic reaction, we performed an analysis of the adverse effects of all administered peroperative drugs and an evaluation of altered operation conditions.Results: MB, used as a per...
