Erythrodontia in congenital erythropoietic porphyria.

Congenital erythropoietic porphyria (CEP) is one of the rarest of porphyrias occurring worldwide. CEP is a very rare genetic autosomal recessive disease, with mutation in the gene that codifies uroporphyrinogen-III synthase, leading to porphyrin accumulation in many tissues, with marked skin photosensitivity, hemolytic anemia with splenomegaly and a decreased life expectancy. We report a case of Gü;nther's disease in view of its rarity along with a description of this interesting condition. An 18-month-old female baby with clinical, hematological and biochemical profile of CEP was reported with marked skin photosensitivity over face and hands. She had erythrodontia with delayed eruption of teeth. When evaluating erythrodontia of uncertain cause, we advocate maintaining a high degree of awareness for porphyria, especially for CEP as it is the rarest among porphyria and is a life-threatening condition.
