Papillary predominant adenocarcinoma of lung

Papillary predominant adenocarcinoma of lung is a subtype of adenocarcinoma of the lung.

It may account for 7-12% of all lung adenocarcinomas. There may be predilection in female non smokers 1.

It this form papillary structures replace the underlying alveolar architecture. True papillary adenocarcinoma is usually diagnosed when the pathological features constitute >75% of the tumour on histopathology.

Variable appearances have been described randing from a solitary pulmonary nodule, as a mass containing internal bubble lucencies with surrounding ground-glass opacity and satellite micronodules or as a triangular mass with satellite micronodules 2.

The presence of micropapillary component in papillary carcinoma has been associated with early lymph node metastasis, intrapulmonary metastasis and a significantly lower 5-year survival rate 1.
