Malignant Lung Pathology Flashcards
what are the most common sites of lung metastasis
bones, brain, lymph nodes
what is the most common type of lung tumour
carcinoma with adenocarcinoma being the most common subtype
what are the two classifications of lung carcinomas
small cell - less cytoplasm, fine nucelar chromatin
non-small cell - more cytoplasm, clumped
what is the prognosis of small cell carcinoma and what is the stain
poor - late onset metastasis to many body sites
cells stain dark blue due to little cytoplasm
what are the three subtypes of non-small cell carcinomas
squamous cell
adenocarcinoma - most common
large cell undifferentiated - no keratinisation
what are these three primary malignant lung tumours
carcinoid tumours
malignant mesenchymal tumours
primary lung lymphomas
rare and low grade - better prognosis
very rare - synovial sarcoma
rare - often seen in HIV patients
what are the most common type of secondary lung tumours
carcinomas from any other body part of the lung
which cancer is the most common to kill and who does it affect more
lung cancer
males more than females with 40-70 y/o
what are the main causes of lung cancer
smoking
asbestos
what disease are associated switch asbestos inhalation
lung cancer
mesothelioma
lung fibrosis
what are the local effects of lung cancer
haemoptysis mimics pneumonia chest pain horners snyrome - miosis, partial ptosis and anhidrosis dysphagia
what are the most common sites of lung metastasis
lymph nodes, pleura, lover, bone
what is lymphangitis carcinomatosa
infiltration of lymphatic vesslels by lung cancer cells
what are some non-specific features of lung cancer
weight loss, lethargy, finger clubbing, electrolytic disturbance
