Low cellularity produced from aspirating normal liver tissue is a result of:
vascular nature of the liver
This type of cell comprises 80% of the pancreas parenchyma.
Acinar cells
Scattered groups of uniform cells in small clusters or cords in background of blood and bubby lipid material demonstrate centrally located, uniform, round to oval nuclei with fine chromatin and distinct nucleoli. These cells most likely originate from this location in the adrenals.
Adrenal Cortex
The most common solid extra cranial (outside of the CNS) childhood malignancy is:
Neuroblastoma
The main epithelium type of the prostate is:
Tall columnar, secretory epithelium.
Note: basal cells located on basement membrane
The development of cholangiocarcinoma of the liver and gallbladder is associated with this type of infection.
parasitic infection
These cells produce somatostatin which suppresses gastrointestinal hormones.
Delta
Cells from the adrenal's zona fasciculata produce:
glucocorticoids
Choroid plexus papillomas and carcinomas are childhood tumors arising in this ventricle.
third ventricle
Brenners Tumor arises from this tissue type.
urothelium
In patients with steastosis of the liver, the hepatocytes often have a cytologic pattern of:
numerous cytoplasmic vacuoles
serum amylase
The renin-angiotensin system in the kidney is responsible for the the regulation of:
Hypertension
An aspirate of a well-circumscribed mass arising in the intracranial (CNS) region of a 42-year-old female reveals cohesive, syncytial sheets and cellular whorls of cells with oval and bland nuclei and wispy cytoplasm. Psammoma bodies are noted in the background. The pattern is suggestive of:
Meningioma
This type of tumor can be composed of skin appendages like anucleated squames, sebaceous cells, muscle, cartilage etc.
Mature Teratoma
True or false: Intraductal Papillary Mucinous Neoplasms of the pancreas are more common in females than males.
False
This malignancy shows loss of SMAD4 (DPC4) nuclear expression.
In FNA of the kidney, most of the benign cells aspirated from a normal kidney usually originate from the following structure.
renal tubules
Craniophyarngiomas are derived from epithelial cells originating in this location.
Rathke’s pouch
Sertoli-Leydig Tumors are characterized by mutations of this gene.
DICER1 gene
The most common histologic growth pattern of well-differentiated hepatocellular carcinoma of the liver is:
trabecular pattern
A FNA of a mass in the tail of the pancreas from a 52 year male shows a hypercellular pattern of monotonous single cells with plasmacytoid features, nuclei with salt and pepper chromatin, small nucleoli and sparse to moderate, tail-like, granular cytoplasm. The pattern is consistent with:
Pancreatoblastoma
A middle aged female patient presents with hypertension, hypokalemia, increased serum aldosterone, and low-serum renin. Her adrenal FNA shows small vesicular nuclei and distinct nucleoli and lipid-laden cytoplasm with small cytoplasmic inclusions. This pattern suggests a diagnosis of:
Aldosteronomas
An aspirate of a cystic mass structure in the suprasellar region of the central nervous system (CNS) a 12 year old girl reveals keratinized anucleated squames and fragments of mature squamous cytoplasm in a background of calcified debris. The aspirate was described as brown in color. The pattern is consistent with:
craniopharyngioma
FNA of an eye form a 6 month old baby shows small round blue cells in loose aggregates with very hyperchromatic nuclei in a necrotic background. The most likely diagnosis would be:
