Perhaps you can work from this (not very well tested):
(defun delete-duplicate-lines (beg end)
"Delete consecutive duplicate lines in region BEG..END."
(interactive "r")
(save-excursion
(save-restriction
(narrow-to-region beg end)
(goto-char beg)
(let ((kill-whole-line t)
(last (buffer-substring (line-beginning-position)
(line-end-position)))
(removed 0)
current)
(forward-line 1)
(while (and (< (point) (or end 1))
(not (eobp)))
(setq current (buffer-substring (line-beginning-position)
(line-end-position)))
(if (string= last current)
(progn
(kill-line)
(setq removed (1+ removed)))
(setq last current)
(forward-line 1)))
(message "Duplicate lines removed: %d" removed)))))
