A 54-year-old man is admitted to the hospital with cough and dyspnea, which over a period of years has led to marked respiratory embarrassment and cyanosis. A chest x-ray film of the lungs shows bilateral lower lobe diffuse hazy infiltrates resembling ground glass. Wedge biopsy of the lung demonstrates airspaces filled with macrophages containing lipid, periodic acid-Schiff (PAS)-positive granules, and lamellar bodies. There is an accompanying interstitial pneumonitis, hyperplasia of the septal lining epithelial cells, and desquamation of epithelial cells into alveoli. The lamellar bodies within the macrophages are composed of which of the following?
A. Amyloid B. Calcitonin C. Fibrin D. Hemosiderin E. Surfactant A 55-year-old patient presents with chronic cough. A chest x-ray film demonstrates a circular lesion near the apex of the lung. CT-guided biopsy of the lesion demonstrates a malignant tumor arising in an area of scarred lung. Which of the following type of cancer is most likely to be present? A. Adenocarcinoma B. Bronchioloalveolar carcinoma C. Large cell carcinoma D. Oat cell carcinoma E. Squamous cell carcinoma A 60-year-old man presents to his physician after a routine screening test indicates hyperlipidemia. Physical examination reveals raised, irregular, yellow papules in the skin of the soft tissues below the eyes. Biopsy of these lesions would most likely show which of the following? A. Benign nevus cells B. Malignant nevus cells C. Microscopic blisters D. Munro microabscesses E. Multinucleated giant cells An elderly woman with a history of multiple oral ulcers presents with flaccid bullae on her scalp, face, and trunk. Manual pressure on the skin produces separation of the upper layer of the epidermis, followed by eventual sloughing of the skin. The patient has been in relatively good health until recently, and denies taking any medications. A biopsy of one of the skin lesions reveals separation of epithelial cells above the basal layer. Autoantibodies to which of the following components would most likely be found in this patient? A. Epidermal basement membrane proteins B. Glycoprotein IIb/IIIa C. Intercellular junctions of epidermal cells D. Intrinsic factor E. Type IV collagen A newborn baby is noted to have extremely pale skin, white hair, and red irises. A sibling has similar characteristics. The pediatrician instructs the family to be careful to avoid sun exposure in this child because of the markedly increased risk of developing cancer. Which of the following diseases has the highest incidence in these patients? A. Basal cell carcinoma B. Keratoacanthoma C. Malignant melanoma D. Paget disease E. Squamous cell carcinoma A 24-year-old woman gives birth, at 40 weeks' gestation, to a 7 lb. 4 oz. boy. Examination of the newborn reveals a large nevus flammeus on his face, extending into the scalp on the right side. Which of the following may also be present? A. Acoustic neuromas B. Cerebellar hemangioblastomas C. Leptomeningeal angiomatosis D. Neurofibromas E. Subependymal tubers EM pic Q A 1-year-old boy is referred to a pediatric dermatologist for evaluation of skin lesions. The child's parents report that the lesions appear extremely painful and that they had been spreading since he was born. After a complete dermatologic and hematologic work up, the child is treated with systemic corticosteroids. The dermatologist explains that the child has an autoimmune reaction to the structure indicated by the arrows in the image above. Which of the following best describes the child's skin lesions? A. Local painful blisters on the skin around the oropharynx B. Pruritic maculopapular rash on head and trunk with bluish-gray spots in oral mucosa C. Small red skin spots on body, palms and soles, but sparing the face D. Widespread blistering sparing the oral mucosa with pruritus E. Widespread painful blisters on skin and oropharynx A patient has multiple, pearly papules on the face. Biopsy shows a malignant tumor. Which of the following features would most likely be seen on microscopic examination? A. Cytoplasmic viral inclusions B. Keratin "pearls" C. Melanin D. Palisading nuclei E. S-100 positivity This bladder specimen displays marked thickening of the smooth muscle, resulting in trabeculation of the bladder wall.Which of the following conditions is most likely to result in this change? A. Chronic cystitis B. Neoplasms involving the cauda equina C. Prostatic carcinoma D. Prostatic hyperplasia E. Transitional cell carcinoma of the bladder This gross photograph depicts the peritoneal mesentery of a patient with cancer. The innumerable nodules are composed of metastatic neoplasm. Which of the following tumors is most likely to give rise to this condition? A. Bronchogenic carcinoma B. Carcinoid tumor C. Glioblastoma multiforme D. Hepatocellular carcinoma E. Ovarian carcinoma A 2-year-old girl is brought to the pediatrician for a fever. The physical exam confirms a fever but no source is identified. Generalized lymphadenopathy is also noted. She is admitted to a local hospital for observation. One day later she begins to have swelling of her knees and elbows bilaterally with rubor but no rash. Her liver and spleen are found to be slightly enlarged. She has no nausea or diarrhea. Which of the following is the most likely diagnosis? A. Felty's syndrome B. Henoch-Schönlein purpura C. Kawasaki's disease D. Septic arthritis E. Still's disease A 45-year-old woman has crippling arthritis of her fingers, wrists, and knees. Physical examination demonstrates large subcutaneous nodules near the patient's elbows. Serology demonstrates a positive rheumatoid factor. The patient's probable disease has the strongest association with which HLA type? A. HLA-A3 B. HLA-B27 C. HLA-DR2 D. HLA-DR3 E. HLA-DR4
