A man having multiple, painful, indurated, undermined, sloughed edged glans which occurred 5 days after exposures; most likely diagnosis is –

  1. Chancroid
  2. Primary chancre
  3. Herpes genitalis
  4. LGV

explanation

      Step 1

Painful ulcer → Chancroid or HSV.
Step 2
In the question, there is no information about step 2 → suppurative lymphadenopathy, U/L or B/L lymphadenopathy, presence or absence of vesicle.
So go for step - 3.
Step 3
Induration (+)nt → Chancroid
Undermined sloughed edges → Chancroid
