We report a patient with mycosis fungoides treated with bexarotene (Targretin), a synthetic retinoid analog with specific affinity for retinoid X receptor. This patient developed hypopituitarism characterized by hypogonadism, hypothyroidism, and hypoadrenalism. Although central hypothyroidism is a common side effect of bexarotene, central hypogonadism, and hypoadrenalism has been reported in one case. Clinicians should have high index of suspicion for hypopituitarism in patients under bexarotene therapy. On the other hand, this side effect may be promising for the treatment of TSH-secreting pituitary tumours and Cushings syndrome. In this regard we suggest that bexarotene should be evaluated as a potential therapy for Cushings syndrome in which the available medical drugs have limited efficacy and potential side effects.
