[A case of lung tumorlets with pulmonary carcinoid].
It has been postulated that differential pathological diagnosis of lung tumorlet from pulmonary carcinoid is very important to decide the therapeutic strategy, because both of them are pathologically consisted of similar type of cells originated from same cells. At the present, although lung tumorlet is considered to be a hyperplastic lesion of Kultschitzky cells which is located in the epithelial cell of the bronchial mucosa by stimuli such as hypoxia and inflammation, but it occasionally recognized in the normal lung and the concept that it is a subtype of carcnoid is also undeniable. In this paper, a case of lung tumorlet with minute pulmonary carcinoid suggesting a subtype of carcinoid operated upon in our department is presented. Although simple pulmonary resection is a method of choice for pulmonary carcinoid, but it is still controversial as to therapeutic strategy for the lung tumorlet, because it is a benign entity and not tumorous lesion. However pulmonary resection with a close subsequent followed-up study must be a best method of choice for the case with lung tumorlet includes a minute lesion of carcinoid seen in this particular case.
