[Anaplastic small-cell bronchial carcinoma of the composite type]

The authors report an anatomico-clinical case (with ultrastructural study) of bronchial anaplastic carcinoma with composite, triple differentiation oat-cell subtype. The patient underwent early surgical excision followed by radiotherapy and chemotherapy. With the help of data from the literature concerning this composite subtype which suggests new theories on the histogenesis of bronchial cancer, the authors emphasize the value of surgical treatment for this unusual subtype of anaplastic carcinoma.
