Adenomatoid Tumor, Pleural
Adenomatoid tumor is a benign tumor of mesothelial derivation and is considered a benign form of mesothelioma. This tumor is exceptionally rare in the pleural cavity and presents as an incidental nodule. Adenomatoid tumor most commonly occurs in the genital tract.
Few cases of adenomatoid tumor have been reported in the pleural cavity. However, nearly 1% of hysterectomy specimens harbor this tumor.
Adenomatoid tumor of the pleura has been reported in patients between the fourth and seventh decades.
Among the few cases of pleural adenomatoid tumor reported, 75% occurred in females and 25% in males.
Adenomatoid tumor of the pleura can occur in the visceral or parietal pleura and can involve the upper or lower lung lobes.
Excision is curative but unnecessary for this benign condition.
Adenomatoid tumor of the pleura, similar to other locations, is uniformly benign with no malignant transformation reported.
