ABSTRACT
The parvicellular carcinomas have their matrix in the neurosecretory (enterochromaffin) cells of Kultschitzky's type of the APUD-system. While in about 20% of the patients with a bronchial carcinoma a parvicellular bronchial carcinoma appears, extrapulmonary parvicellular organ carcinomas are very rarely observed. Up to 1984 altogether 72 patients with a parvicellular carcinoma of the oesophagus were world-wide registered. It is reported on an own observation of a female patient with a parvicellular carcinoma of the oesophagus and it is referred to the appearance of extrapulmonary parvicellular carcinomas. According to the present state of knowledge the extrapulmonary parvicellular carcinomas should be treated according to the therapy concepts of parvicellular bronchial carcinomas.
