We present three novel varieties of spiraling and nonspiraling axisymmetric solitons in the complex cubic-quintic Ginzburg-Landau equation. These are irregularly "erupting" pulses and two different types of very broad stationary ones found near a border between ordinary pulses and expanding fronts. The region of existence of each pulse is identified numerically. We test their stability and compare their features with those of their counterparts in the one-dimensional and conservative two-dimensional models.
