A 44-year-old woman has a left level III cervical lymph node. Excision biopsy revealed metastatic squamous cell carcinoma. Head, chest and abdominal CT scans are all negative. Upper airway and upper GI endoscopic examinations are both negative. Next step should be:
A. Colonoscopy

C. Random blind punch biopsies of the nasopharynx.
A 56-year-old male has multiple enlarged tumors in the retroperitoneal and posterior mediastinal region as documented by CT scan studies. He has fever and body weakness. The biggest retroperitoneal tumor is 6cm and is not abutting any major vascular structure or organ. It looks resectable. Next step:
A. Determine alkaline phosphatase level
B. Request for blood alpha-fetoprotein and HCG
C. Perform a percutaneous CT scan guided needle biopsy of the most accessible tumor.
D. Do debunking surgery to minimize tumor load.
C. Perform a percutaneous CT scan guided needle biopsy of the most accessible tumor.
A patient presents with hypercalcemia. What is the most useful modality to detect the lesion?
A. CT scan of the whole abdomen
B. Renal ultrasonography
C. Sestamibi scan

C. Mammographic needle localization biopsy
If the result of the biopsy is cancer, what will you request to be done to the specimen:
A. ER and Progesterone status; Her2neu
B. ER and Progesterone status
C. Her2neu
D. S phase and DNA policy
B. ER and Progesterone status
A patient has a suspicious melanoma-looking 2cm lesion in the right forearm. The next procedure should be:
A. Wide excision with a 3cm margin of the skin with reconstruction
B. Wide excision with a 3cm margin and resection of the underlying muscles with reconstruction
C. Sentinel lymph node biopsy
D. Full thickness incisional biopsy
D. Full thickness incisional biopsy
True statement on total mesorectal excision:
A. The circumferential resection margin is an important predictor of local and distant recurrence as well as the survival of patients.
B. Lympazurin dye is applied to the specimen before fixing it with formalin.
C. The minimum number of lymph nodes to be harvested for rectal cancer according to AJCC and American College of Pathologists is 8.
D. It is the treatment of choice for a 1cm anal cancer.
A. The circumferential resection margin is an important predictor of local and distant recurrence as well as the survival of patients.
A 55-year-old male was diagnosed with a 1.5cm papillary thyroid cancer by fine needle biopsy. Work-ups should include:
A. Liver ultrasonography
B. Bone scan
C. Serum calcium
D. Chest x-ray
D. Chest x-ray
The best diagnostic modality to detect distant metastasis from a cutaneous melanoma of the thigh is:
A, Ultrasonography of whole abdomen and pelvic region
B. Bone scan
C. PET-CT Scan
D. Sentinel node biopsy using technetium and lymphazurin
C. PET-CT Scan
A 55-year-old male was noted to have a 7cm squamous cell carcinoma of the left parotid gland by frozen section. What will be your next step after total parotidectomy?
A. Offer 5-FU based chemotherapy for the patient
B. Chest CT scan
C. Supraomohyoid lymph node dissection/sampling
D. Bone scan
C. Supraomohyoid lymph node dissection/sampling
By ultrasonography, a 44-year-old man has a 7cm pancreatic tail tumor involving the spleen. There are multiple enlarged lymph nodes near the spleen. CA-19-9 is very high. What will you do next.
A. En-bloc resection of the tail of the pancreas and spleen with lymph node dissection
B. CT scan of the chest
C. Endoscopic ultrasound
D. En-bloc resection of the tail of the pancreas and spleen with lymph node dissection, chemotherapy, and radiation treatment
B. CT scan of the chest
A 55-year-old male patient underwent total thyroidedctomy 20 years ago for a 3cm follicular carcinoma of the left lobe. He now presents with a 3cm nodule in the left parietal bone underlying the scalp. What is the next best procedure of choice?
A. Incision biopsy of the mass
B. Excision biopsy of the mass
C. MRI of the head
D. Observation
C. MRI of the head
A 65-year-old woman by CT scan has multiple midline retroperitoneal masses. The sizes range from 2-9cm in widest dimension. There is associated enlarged para-aortic lymph nodes. Best procedure of choice:
