Method of histological control of the edges of surgical specimens of basal cell epitheliomas

For histologic control of excisional margins, routinely fixed tumor specimens or under certain conditions, specimens fixed immediately in warm formalin are processed in the histology laboratory. Strips are then cut from the undersurface, edge and cross section of the specimen and processed further by routine paraffin techniques until HE-stained sections of the entire periphery and midsection are available. The average follow-up time was of 4 years with a recurrence rate of 0.4 per cent.
