Association of oral-facial-digital syndrome type VI (Varadi-Papp syndrome) with optochiasmatic pilocytic astrocytoma.

Abstract

INTRODUCTION:

Varadi-Papp syndrome (VPS) or oral-facial-digital syndrome type VI (OFDS-VI) is a rare autosomal recessive disorder distinguished from other OFDSs by metacarpal abnormalities with central polydactyly and by cerebellar abnormalities. It can be associated with central nervous system tumors, which most commonly has been a hypothalamic hamartoma.

CLINICAL CASE REPORT:

The boy had unusual facial features, developmental delay, limb malformations, and other phenotypic anomalies suggestive of VPS. X-ray of the hand and feet showed right hand polydactyly. He also had a deep wider peduncular fossa, thickened superior cerebellar peduncle, and inferior vermian hypoplasia along with optochiasmatic tumor. The patient underwent a right pterional craniotomy and tumor decompression. Histopathology was suggestive of a pilocytic astrocytoma.

CONCLUSION:

This is the first case in available literature in which the OFDS-VI has been associated with an optochiasmatic pilocytic astrocytoma. We suggest an expansion of the disease spectrum of OFDS-VI to include the association of optochiasmatic pilocytic astrocytoma.
