ABSTRACT
Introduction: Adenocarcinoma is the most common form oflung cancer. It is a type of non small cell carcinoma of lung,most commonly seen in women. Adenocarcinoma occurs inmore peripheral lung location and may be associated with thehistory of smoking.Case report: A 54 year old female caretaker presented withcough with expectoration since 1 month, gradual in onset,non progressive, scanty in amount associated with decreasedappetite since 1 month and breathlessness on exertion since 1week. She had a history of exposure to tuberculosis patient andwas diagnosed with meningioma. There was history of passivesmoking. General examination showed right supraclavicularlymph node enlargement. Respiratory examination showeddecreased chest movements bilaterally along with coarsecrepitation all over lung fields along with decreased intensityof breath sounds bilaterally. Chest x-ray was suggestive ofmetastasis. HRCT chest also suggested metastasis. FNAClymph node and sputum of cytology suggestive of metastaticadenocarcinoma. USG abdomen and pelvis as well as CECTabdomen was done to rule out primary lesionConclusion: As survival rates vary significantly depending onthe type of adenocarcinoma, the survival rate after five yearsdepends on the stage of cancer. So early detection is criticalfor better outcome. The prognosis for different metastaticpattern of intrathoracic metastasis of Lung distinct in EGFRmutant lung adenocarcinoma patient. Early diagnosis andprompt initiation of treatment is key for the prognosis.
