      OBJECTIVES: To highlight the difficulty in making a correct diagnosis of benign schwannoma in the paranasal region, to raise awareness of this rare condition, and to suggest the most appropriate treatment. METHOD: Retrieval of cases retrospectively from archives of the histopathology department of a major UK cancer centre with central review of all cases. RESULTS: Five cases were identified since 1990 and clinical and pathological features are summarised. Median follow up of patients was 8.1 years. Radiological appearances of local bone invasion and histological features of tumour unencapsulation and hypercellularity could give the mistaken impression of malignant disease and lead to unnecessary over-treatment. CONCLUSION: Central pathological review and clinical awareness is required. Although local recurrence can occur, the prognosis is excellent. The treatment of choice is local excision. Radiotherapy can be considered, but in most cases it would incur unnecessary morbidity.

      Relapse following adjuvant paraaortic radiation therapy in patients with Stage I seminoma is rare, occurring in approximately 4% of men. The majority of relapses are sited in the pelvis but relapse in the mediastinum is also recognised. As such, radiological imaging using chest radiographs remains commonplace in follow-up. However, there are reports of the association of testicular cancers with sarcoidosis and sarcoid-like processes in the mediastinum, emphasising the importance of making histological diagnosis prior to commencement of any treatment. We report on two men treated for testicular seminoma who on follow-up developed mediastinal lymphadenopathy, which was initially assumed to be metastatic seminoma. Both patients underwent mediastinascopy and biopsy prior to commencement of anti-cancer therapy. In both cases, the biopsies showed sarcoidosis, and unnecessary anti-cancer treatment was avoided.
