KROK 1 2013 – Question 157 · KROK (Medicine) · Pathophysiology
A 22-year-old woman ate some seafood. 5 hours later the trunk and the distal parts of limbs got covered with small itchy papules which were partially fused together. After one day, the rash disappeared spontaneously. Specify the hypersensitivity mechanism underlying these changes:
- A. Cellular cytotoxicity
- B. Antibody-dependent cell-mediated cytolysis
- C. Immune complex hypersensitivity
- D. Systemic anaphylaxis
- E. Atopy (local anaphylaxis)
Hint
Think about the speed of onset, the itch, the transient skin-limited rash and how widespread the body's response is, then place it among the hypersensitivity types.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
