What are the four types of bronchogenic carcinoma?
|
Squamous Cell Carcinoma
Adenocarcinoma Large Cell Carcinoma Small Cell Carcinoma |
|
Anatomically, what area is most commonly affected in Squamous Cell Carcinoma?
|
Large bronchi
|
|
Histologically, what will you see wtih squamous cell carcinoma?
|
keratin pearl/cellular bridge
|
|
If you saw keratin pearls and cellular bridges on biopsy from a large bronchi what should you be thinking?
|
Squamous cell Carcinoma
|
|
Adenocarcinoma is most commonly seen in what population?
|
nonsmoking females
|
|
Basic features of papillary carcinoma?
|
little or no mucous production, tall columnar cells without cilia
|
|
Basic features of bronchioalveolar carcinoma?
|
exhibits a 'lipidic' growth pattern
|
|
What is the nucleus to cytoplasm ratio (in general) for a large cell carcinoma?
|
the nucleus is HUGE relative to a moderate amount of cytoplasm
|
|
What is the histological growth patter for adenocarcinoma?
|
honeycomb pattern
|
|
This is a list of all the buzz words for Squamous Cell Carcinoma.
|
large bronchi, keratin pearl, cellular bridge
|
|
Neuroendocrine carcinoma originates from what type of cell?
|
Kulchitsky cell
|
|
Carcinoid tumors arise where and look like what?
|
These tumors are similar to large cell carcinomas; arise anywhere from main to segmental bronchi; iceburg shaped, well defined, glossy and pink
|
|
What are the EM findings for carcinoid tumors?
|
the cells have dense core granules and are positive for seratonin
|
|
What are the EM findings for small cell carcinomas?
|
neurosecretory granules, present in a cytoplasmic process/beneath the cell membrane
|
|
TNM: grading refers to...
|
level of differentiation
|
|
TNM: staging refers to...
|
extent of cancer
|
|
What is a hamartoma?
this wasn't on his quizetta, but you should know it!!! |
Abnormal mix of cell and tissue in an area of the body where that growth occurs normally!!!
|
|
What is a branchial cleft cyst?
|
A growth of lymphoid infiltrate (aka it has germinal centers) found on the lateral aspect of the neck
|
|
In what population do we usually see a branchial cleft cyst?
|
Older children!
The branchial cleft fails to close during embryonic development. Even though this is a congenital defect, it is not noticable at birth. |
|
What is the most common trancheoesophageal fistula?
|
87% are esophageal atresia with distal tracheoesophageal fistula
|
|
Kids with a tracheoseophageal fistula will present how?
|
excessive salivation, choking, coughing, vomiting and cyanosis with feeding
|
|
What is pulmonary sequestration?
|
Discrete mass of lung tissue without any normal connection to airway system; blood supply comes directly from aorta
I would read Robbins p. 713 |
|
What are the three types of congenital cyctic adenomatoid malformation? which is most common? which has a good prognosis? which has a poor prognosis?
|
I- large cysts, most common, good prognosis
II- small cysts, poor prognosis, associated with other chest abnormalities III- solid cysts |
|
this is a true papillar adenoca --> bronchial surface cell type with little or no mucus production...it is also composed of tall columnar cells arranged in a tubular fashion
|
Papillary carcinoma
|
|
this occurs in the pulmonary parenchyma and is almost always in the peripheral portion of the long...The growth pattern is lepidic. What is this?
|
BRONCHIOLOALVEOLAR CA
|
|
this is An undifferentiated malignant epithelial tumor that has cells with large nuclei and affects males to females in a ratio of 4:1
|
Large cell carcinoma
|
|
this can be found in the major bronchi, and is either bicameral or iceberg shaped...it is well-defined with a smooth lobulated or granular ivory to pink glistening cut surface...
|
Carcinoid tumors
|
|
these tend to show more cellular atypia, increased cellularity, nucleoli, lymphatic invasion and disorganized architecture...
|
atypical carcinoid
|
|
the micro findings of:
ill-defined cell borders, finely granular chromatin (salt & pepper), round, oval or spindle shpaed cells... are consistent with? |
SMALL CELL CARCINOMA
|
|
this is the most aggressive of lung tumors, it metastasizes widely and is virtually incurable via surgery...
|
small cell carcinoma
|
|
seen in young kids, Air enters lungs but cannot leave easily
Lungs become over-inflated Causes respiratory function to decrease Air leaks out into space around lungs... |
CONGENITAL LOBAR EMPHYSEMA
|
|
this is a discrete mass of lung tissue without any normal connection to the airway systems....what is this?
Where does it get it's blood from? |
Pulmonary Sequestration
Blood supply – NOT from the pulmonary arteries – but from aorta or its branches |
|
what is an extralobar sequestration
|
Portion of lung tissue develops outside normal lung
|
