BACKGROUND: Previous reports on the cutaneous manifestations of ataxia-telangiectasia (A-T) have relied on data from small series, in patients not genetically tested for A-T.
OBJECTIVE: The aim of our study was to characterize the dermatologic manifestations in patients with A-T followed up at the national A-T clinic in Israel.
METHODS: This retrospective cross-sectional study included 32 patients followed up at a multidisciplinary A-T clinic from 2010 to 2012. Complete skin examination was done by a single dermatologist. Information about mutations and neurologic status was extracted from the patients' charts. Relevant demographic, clinical, and laboratory characteristics of all patients were collected and summarized.
RESULTS: Of the 32 patients, 97% had ocular telangiectasia, the hallmark of the disease. Telangiectasia on other body parts was less frequent. Pigmentary anomalies included café-au-lait macules (84%), hypopigmented macules (44%), and melanocytic nevi (37%). A facial papulosquamous rash was found in 41% of cases. Other manifestations included hypertrichosis and birdlike facies. We did not observe premature hair graying or poliosis. No genotype-phenotype correlation was found in terms of skin manifestations.
LIMITATIONS: There was a modest sample size, because of the rarity of the disease.
CONCLUSION: Recognition of the ocular and dermatologic manifestations of A-T can facilitate early diagnosis in a child with neurologic deterioration.
