Neoadjuvant chemotherapy in well-differentiated fetal adenocarcinoma: a case report

BACKGROUND: Fetal adenocarcinoma of the lung is a rare subtype of pulmonary adenocarcinoma with a relative estimated incidence of 0.5% or fewer of all lung cancers. Because of its extreme rarity, there have been no controlled clinical trials investigating treatment regimens for fetal adenocarcinoma and, as a result, there are no guidelines for management. CASE PRESENTATION: We report a case of a well-differentiated fetal adenocarcinoma, which is a variant of pulmonary blastoma, that is a low-grade malignancy and associated with a good prognosis. A 29-year-old Moroccan man presented with a well-differentiated fetal adenocarcinoma staged T3N0M0, who received 3 cycles of neoadjuvant chemotherapy followed by surgery, with no recurrence at 2 years follow-up. CONCLUSION: Fetal adenocarcinoma is a rare suptype of adenocarcinoma. Surgical resection is the treatment of choice for resectable disease. The role of chemotherapy in the neoadjuvant setting or adjuvant setting is not well defined

Le goitre ectopique endothoracique est une maladie rare, il représente moins de 1% de l’ensemble des goitres endothoracique, son diagnostic positif est parfois difficile et repose sur les données de l’imagerie. Le traitement est chirurgical en raison des risques de compression et de dégénérescence maligne.
