Pulmonary neuroendocrine carcinoid tumors: Is there a predictive role to the Ki 67 index?

Introduction: There are several factors predicting evolution in carcinoid tumors (CT) to date including the Ki67 role.

Aims: The aim of this study is to identify a KI67 cut-off point for a population of CT and determine its prognostic implication in global and disease-free survival.

Methods: Hematoxylin-eosin slides of 102 CT were revised.

[Placental transmogrification of the lung. Atypical presentation of the bullous emphysema].

Placental transmogrification of the lung is an extremely rare lesion, associated with giant bullous emphysema and considered by some authors to be a histological variant of unilateral giant bullous emphysema. Its etiology is still unknown and represents a challenge for both clinical and pathological diagnosis. We present the case of a young patient, who consults with dyspnea of one year of evolution, and whose postoperative diagnosis includes this rare entity.
