Malignant peripheral nerve sheath tumor of the parapharyngeal space arising from cervical sympathetic chain: A rare entity

Malignant peripheral nerve sheath tumors (MPNSTs) of parapharyngeal space are rare and if present are most often in association with neurofibromatosis type 1 (NF-1). Only a few cases of MPNST have been reported in the literature without coexisting NF. We report one such case of an MPNST of parapharyngeal space tumor in a 35-year-old female with no associated features of NF-1. She presented with right-sided neck swelling and ptosis. Magnetic resonance imaging showed a 7 cm × 8 cm × 11 cm irregular swelling in the right parapharyngeal space with invasion of surrounding muscles. The mass was excised using a transcervical approach. Postoperative histopathological examination of the specimen revealed MPNST possibly arising from the cervical sympathetic chain

Congenital orbital teratoma presenting as microphthalmos with cyst.

We report a rare case of non-communicating large orbital cyst with microphthalmos which was surgically separated from the globe and excised. Histopathology reported it to be a teratoma. Congenital cystic teratoma should be a part of the differential diagnosis in an infant presenting with a clinical picture of microphthalmos with orbital cyst, in view of the different management required.
