Neonatal lupus is a rare disease caused by the transplacental transfer of maternal
autoantibodies to the foetus, characterized by transient clinical manifestations such
as cutaneous, haematological, and hepatobiliary events or permanent such as
congenital heart block. The typical cutaneous manifestations include erythematous,
scaly, annular or arched lesions on the face, with slight central atrophy and
photosensitivy, clinically and histologically similar to subacute cutaneous lupus.
However, in some cases, the lesions may resemble those in cutis marmorata
telangiectatica congenita, although this phenomenon is rare and only eight such cases
have been reported to date. We report a case of cutaneous neonatal lupus with
atypical lesions on the limbs, which had a reddish-purple marbled appearance,
resembling the lesions in cutis marmorata telangiectatica congenita.
