Síndrome de Pai: dos nuevos casos con manifestaciones inusuales / Pai syndrome: Two new cases with unusual manifestations

El síndrome de Pai se describe como la presencia de 3 anomalías congénitas: fisura de labio medial, pólipos cutáneos nasales y faciales, y lipoma pericallosal. La expresión clínica es variable. El desarrollo neuromadurativo suele ser normal. Existen 42 casos descritos en la literatura. Se proponen distintos tipos de herencia, pero, hasta la actualidad, no existe un gen asignado para esta patología. Se presentan dos pacientes con síndrome de Pai, uno de ellos con hallazgos clínicos aún no descritos (defectos de segmentación vertebral y osteoma coroideo).

Pai syndrome is a very rare congenital disorder characterized by medial cleft lip, nasal and facial cutaneous polyps, and pericallosal lipoma. Broad phenotypic variability exists in this condition. Neurodevelopment is usually normal. Up to date 42 cases have been reported in the literature. Different types of inheritance have been proposed, but most cases are sporadic. No gene has been identified. We report two cases with Pai syndrome, one of them with novel clinical findings as vertebral segmentation defects and choroidal osteoma.

A Case of Pai Syndrome: First Reported Case in Korea / 대한주산의학회잡지

Pai syndrome is a rare disorder, first described in 1987. Diagnostic criteria are the presence of the nasal polyp and one of the following: midline cleft lip, congenital polyp of mid-anterior alveolar process, and pericallosal lipoma. Thirty-six cases of Pai syndrome have been described so far. We report 1 case of Pai syndrome accompanied by congenital nasal polyp and callosal lipoma with partial agenesis of corpus callosum, the first time in Korea.
