Bullous skin lesions in a jaundiced infant after phototherapy: a case of congenital erythropoietic porphyria.
نویسندگان
چکیده
Congenital erythropoietic porphyria is a rare autosomal recessive disorder of porphyrin metabolism in which the genetic defect is the deficiency of uroporphyrinogen III cosynthase (UIIIC). Deficiency of this enzyme results in an accumulation of high amounts of uroporphyrin I in all tissues, leading to hemolytic anemia, splenomegaly, erythrodontia, bone fragility, exquisite photosensitivity, and mutilating skin lesions. We discuss a female infantile case who was admitted for jaundice; bullous lesions appeared on her trunk during phototherapy in the neonatal period. The skin biopsy findings were consistent with epidermolysis bullosa. Due to persistent hepatosplenomegaly and cholestasis, metabolic tests and liver biopsy were performed. During the follow-up, hemolytic anemia and red urine were detected. The levels of porphyrin metabolites were determined at high concentrations in plasma, stool and urine analysis, which were suggestive of congenital erythropoietic porphyria.

Congenital Erythropoietic Porphyria: Mutation of the Uroporphyrinogen III Cosynthase Gene in a Vietnamese Patient
Congenital erythropoietic porphyria (CEP) arises from an autosomal recessive inherited disorder of the porphyrin metabolism, which leads to the accumulation of uroporphyrinogen I in bone marrow, skin and several other tissues by a deficiency of uroporphyrinogen III cosynthase (UROS). We studied a Vietnamese patient and her family suffering from severe cutaneous photosensitivity with skin fragil...

ECENT STUDIES” 2, 3 have emphasized that in human beings, photosensitivity occurs as a result of two fundamentally different disturbances of porphyrin metabolism. In porphyria cutanea tarda, in which the excessive porphyrin formation is believed to take place in the liver, symptoms are seldom manifest before adult life.’ Its porphyria erythropoietica (congeisital, photosensitive), where large a...
