Abstract
A silver colloid technique to identify nucleolar organizer region associated protein (AgNOR) has been applied to 68 cutaneous tumours. Basal cell carcinomas, eccrine tumours, apocrine tumours, and hair follicle tumours had differences in their numbers of AgNORs; these appeared as small black dots in their nuclei. Dermatofibromas and squamous cell carcinomas showed a degree of variability in the number of AgNORs depending on the cellularity of the former and differentiation of the latter. Basal cell carcinomas possessed significantly many more AgNORs per nucleus than the other neoplasms. It is suggested that this technique, previously the province of the cytogeneticist, may be of use in the diagnosis of cutaneous neoplasms.
