Pseudoxanthoma elasticum is a rare, hereditary, multisystemic disease affecting skin, eyes, and the cardiovascular system. A 28-yearold female presented to the emergency unit with the complaint of gastrointestinal hemorrhage. Patient history revealed that she had been monitored in the gastroenterology clinic more than 10 times in the past 8 years, and had repetitive hemorrhage during her previous pregnancy. The examination of the patient revealed the following signs and symptoms: atrophy in the epithelium of the retina pigment; typical angioid streaks and peau d’orange finding in the fundus; thinning of the retinal nerve fiber in optic coherence tomography; bilateral and reticular papillary lesions with yellowish-color in the neck region (plucked chicken appearance); presence of bleeding foci in fundus; and nephrocalcinosis in kidneys. In light of these symptoms, the patient was diagnosed as pseudoxanthoma elasticum, which was also confirmed on skin biopsy. Pseudoxanthoma elasticum is an uncommon hereditary disease. Early diagnosis of pseudoxanthoma elasticum cases is important to minimize systemic complications and to inform the other family members through genetic counseling.
