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 with AIHA. After 2 years of therapeutic course she developed ocular telangiectasia and ataxic gate. Conclusion: This case emphasizes the possibility of ataxia telangiectasia coexistence with autoimmune disorders and must be taken into consideration by physicians.
