Intracerebral cystic rhabdoid meningioma

A 36-year-old woman presented to our hospital with a short history of intermittent headaches. An MRI of the brain revealed a left temporal intracerebral cystic lesion with rim enhancement. Histopathology showed a malignant tumour with features of rhabdoid differentiation. Immunohistochemistry revealed that vimentin, epithelial membrane antigen and S-100 were positive, and that glial fibrillary acidic protein and the chromosome deletion 1p/19q were negative. The patient was diagnosed as having an intracerebral cystic rhabdoid meningioma. She was treated with surgery and post-operative radiotherapy. Cystic intracerebral rhabdoid meningiomas are rare. We discuss the clinical picture of this patient with reference to the published literature on this uncommon diagnosis.     

Head and neck squamous cell carcinoma: the role of post-operative adjuvant radiotherapy

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is one of the leading cancers in India. Since a large majority present in loco-regionally advanced stages, surgery followed by adjuvant post-operative radiotherapy (PORT) has been the mainstay of treatment for resectable HNSCC. AIM: To identify clinico-pathologic factors that could have an impact on outcome in HNSCC in the postoperative setting. MATERIALS AND METHODS: A retrospective review of 348 previously untreated patients with HNSCC who received PORT following curative surgery. The outcome measures were local control, loco-regional control, and disease free survival (DFS). RESULTS: With a median follow-up of 36 months (range: 2-127 months) for surviving patients, the 5-year local control, loco-regional control, and DFS was 79%, 63%, and 56%, respectively for all patients. On univariate analysis, site of primary was an independent prognostic factor for all the outcome measures (P = 0.005, 0.02, and 0.04, respectively) with oral cavity lesions faring the worst. Peri-nodal extension (PNE) affected loco-regional control (P = 0.002) and DFS (P = 0.0005), but was not predictive for local control (P = 0.9852). Cut margin positivity predicted for inferior local control alone (P = 0.03), the significance of which was lost on multivariate analysis. Cox regression analysis however confirmed the significance of primary site and PNE as independent prognostic factors. CONCLUSION: Primary site and PNE are independent factors predicting outcome in the postoperative radiotherapeutic management of HNSCC.
