"Carcinoid tumorlets". Case report and review of the literature

It is reported a case of "carcinoid tumorlets" of the lung, in a 63-year-old woman, who underwent surgery for a breast cancer. These lesions are histologically similar with carcinoid, but different for clinical evolution. They are benign lesions generally without metastasis. The authors point out the importance of histological, clinical and diagnostical aspects, and the follow-up of patients in order to have evidence of the eventual malignant evolution.
