RESUMO
Isolated necrotizing granulomatous vasculitis of the spermatic cord has not been described during the last 20 years. We report clinical, laboratory and histopathological features of an instance of contralaterally recurrent lesions of this type in a young photographic laboratory technician. Although to date the disease is considered to be isolated, it may well be a systemic one without yet obvious signs.

Chronic herpetic laryngitis, with or without involvement of the oropharynx, is uncommon. We describe a case that was initially diagnosed and treated as squamous cell carcinoma. The subsequent course of the disease, review of the histologic material, and additional laboratory investigation suggested that the lesion was of viral origin and probably was caused by herpes simplex.

Examination of pancreases from a series of 207 autopsies of adults without either clinical or autopsy evidence of insular hyperfunction showed minimal nesidioblastosis in 36.7%. Ductulo-insular complexes, together with insular cells among the acini, were found in 10.6% of the biopsy specimens. Nesidioblastosis was more frequent in men (61.8%), and the oldest individual was an 84-year-old man. Ductulo-insular complexes and the aggregations of insular cells in the exocrine parenchyma develop asynchronously and may have been initiated by different stimuli. This series did not explain the possible causative factors.

A metastasizing functioning pleomorphic carcinoma of the thyroid displayed a morphologic piture ranging from follicular to sarcomatous and carcinoid-like patterns. Spindle-cell elements were believed to be the result of metaplasia of the follicular epithelium. Development of carcinoid-like lesions in the secondary deposits of tumour supported the contention that so-called parafollicular or c-cells may be a phenomenon of metaplasia and not a histologic entity. The tumour was associated with a chromophobe adenoma of the pituitary and a benign schwannoma of the stomach. Clinically the patient did not show any other endocrinologic abnormalities and lived for 4 years from the time of diagnosis of the thyroid tumour.

Use of Système International d'Unités (SI) for laboratory measurements was instituted Jan. 1, 1975 at two community hospitals. Beforehand, talks were given, pamphlets, conversion tables, new calibration curves and new master record cards were printed, computer cards were reprogrammed and conversion kits were prepared; the total cost was less than $200. After 6 months 16% of the medical staff had stopped converting SI units into conventional units, 78% were still occasionally converting units and 6% were routinely converting units. Changeover had been difficult for 25%, only a nuisance for 49% and easy for 26%. The patients' lives were not endangered by conversion.
