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.

Intra-operative autotransfusion--a simple and cost effective method.

Recovery of intrathoracic and intraperitoneal blood and reinfusion by autotransfusion has been demonstrated to be safe and practical in selected cases. This study has basically aimed at using a very simple method for collection and reinfusion of blood in haemothorax and haemoperitoneum. Autotransfusion was done in 50 cases admitted in Dayanand Medical College and Hospital, Ludhiana who were diagnosed to have haemothorax or haemoperitoneum which fulfilled the set criteria. There were increased haemoglobin levels in 26 patients and a decreased haemoglobin in 24 patients. The coagulation profile was deranged in 7 patients pre-operatively while it was deranged in only 2 patients postoperatively. There was no significant change in renal function tests and liver function tests preoperatively and postoperatively. This study had shown that intra-operative autotransfusion with this very simple, affordable and easily available technique is feasible and practical and its use should be encouraged.

Intralesional steroid induced histological changes in the skin.

Intralesional steroids are commonly used in dermatology. Besides their strong anti-inflammatory effects, the long acting steroids and other preservative agents may induce interesting histopathological changes, which may simulate focal mucinosis or a granulomatous pathology. A variety of histopathological changes induced by Intralesional injection of steroid in a lesion of keloid are being described.
