[Malignant exophtalmos in hyperthyroidism with a hypothyroid crisis].

CASE REPORT: We present the case of a 56-year-old male with a malignant exophthalmos in the context of Graves' disease. He suffered a significant worsening coincident with a hypothyroid crisis, and various therapeutic approaches were required for reduction of the proptosis. DISCUSSION: When managing this condition, both the severity of the exophthalmos and the activity of the thyroid must be considered when choosing which of the different therapeutic approaches should be employed.
