Atypical Bronchial Carcinoid Tumor Revealed by Liver Biopsy
Bronchial carcinoid tumors develop from the Kulchitsky cells of the bronchial epithelium, which are stem cells with neuroendocrine properties.

Sumario: | Bronchial carcinoid tumors develop from the Kulchitsky cells of the bronchial epithelium, which are stem cells with neuroendocrine properties. These tumors are divided into two types: typical forms and atypical forms, the latter being much rarer, more aggressive, and having a much higher probability of recurrence and distant metastasis. We report herein a rare case of an atypical lung carcinoid tumor metastatic to the liver. The patient is a 79-year-old woman who presented with purely digestive symptoms evolving for two years, with loss of appetite and deterioration of her general condition. The radiological assessment showed a pulmonary lesion with secondary hepatic and osseous nodules. A hepatic biopsy was performed and morphological and immunohistochemical results were compatible with an atypical bronchial carcinoid tumor, metastatic to the liver and bone. |
