Autoimmune hemolytic anemia in a patient with probable ataxia telangiectasia: a case report.

BACKGROUND Ataxia telangiectasia (AT) is one of the combined immunodeficiency syndromes with immunologic, neurologic, endocrinologic, hepatic and cutaneous abnormalities. Regarding the fact that autoimmune disorders; such as autoimmune hemolytic anemia (AIHA), are not generally expected in the course of AT, we present a patient with an unusual presentation of these two conditions. CASE PRESENTATION An otherwise seemingly normal girl, who had developed limping at the age of 11 months old, referred to Namazi Hospital, Shiraz, Iran, due to pallor and latitude at the age of 3 yrs and was diagnosed of AIHA. After 2 years of therapeutic course she developed ocular telangiectasia and ataxic gate. CONCLUSION This case emphasizes on the possibility of ataxia telangiectasia coexistence with autoimmune disorders that must be taken into consideration by physicians.
