Most common cause of priapism in children?
sickle cell disease
PCT has defective
uroporphyringogen decarboxylase, prophyrins accumulate in the skin causing photosensitization.
Blisters, urine appears red or brown (dark colored), pigmentation on skin.

Howell Jowell Bodies associated with
Hereditary spherocytosis –> normocytic anemia
See Heinz bodies or bite cells think
G6PD deficiency –> normocytic anemia
Defect in PIGA gene = decrease in CD55 (DAF) + CD59
Paroxysmal nocturnal hemoglubinuria - normocytic anemia
low iron, low hepcidin, increased ferritin, decreased TIBC

Iron deficiency anemia
symptoms of severe anemia, pallor, fatigue, cyanosis, webbed neck, cleft palate, triphalangeal thumbs
Diamond Blackfan anemia
ineffective erythropoiesis, and patients typically present within the first year of life with a nonmegaloblastic, macrocytic anemia and structural defects. Decreased reticulocytes and increased fetal hemoglobin
Diamond Blackfan anemia
early childhood, failure to thrive, delayed development, and a megaloblastic macrocytic anemia that does not improve with supplementation of folate and vitamin B12.
orotic aciduria
autosomal recessive defect in uridine monophosphate synthase
orotic aciduria –> elevated orotic acid in serum
