Papillary-predominant adenocarcinoma of the lung
Updates to Article Attributes
Papillary predominant adenocarcinoma of the lung is a subtype of adenocarcinoma of the lung.
Epidemiology
It may account for 7-12% of all lung adenocarcinomas. There may be predilection in female non smokers-smokers 1.
Pathology
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.
Radiographic features
CT
Variable appearances have been described randingranging 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.
Treatment and prognosis
The presence of a micropapillary component in papillary carcinoma has been associated with early lymph node metastasis, intrapulmonary metastasis and a significantly lower 5-year survival rate 1.
