Photosensitivity, abnormal porphyrin profile, and sideroblastic anemia.
Cutaneous photosensitivity in a 43-year-old man with idiopathic sideroblastic anemia associated with an abnormal porphyrin profile is reported. This condition was associated with elevated free erythrocyte porphyrin, plasma protoporphyrin, urine porphyrins (predominantly coproporphyrin), stool porphyrins (predominantly protoporphyrin), decreased ferrochelatase activity, and deletion of portions of the long arms of chromosomes 18 and 20. Five other patients with sideroblastic anemia and abnormal porphyrin profiles have been described; all but one of these patients had photosensitivity. The porphyrin profile of this patient is similar to that of three other previously described patients.
