[Sutton's periadenitis mucosa necrotica recurrens. An optical-ultrastructural case study]

An optic-ultrastructural study is realized, emphazising the presence of: a) Intermediate lymphocytes, that we interpret as T-activated; b) Activated endothelial cells (prominent, rich in Weibel-Palade's bodies, well developed nuclei- and cytoskeletons); c) Classic and native myofibroblasts, partially responsible for the cicatricial contraction. We postulate that the changes in the connective-vascular tissue of the chorion represent an anarchic and reactive fibroangioblastic hyperplasia and favors the typical recurrences of this process.
