Postoperative carbon pigment granuloma: a report of eight cases involving the ovary.

ABSTRACT

Eight cases of ovarian granuloma containing carbon pigment are described. In all cases, this distinctive lesion occurred at sites of prior laser or fulguration surgery. Three types of carbon pigment granuloma were noted, the most common being the necrobiotic granuloma. Although postoperative necrobiotic granulomas have been described in a variety of clinical sites, the carbon pigment granuloma has not been well described in the pathology literature. Recognition of this lesion seems to be of value in determining its postoperative, noninfectious nature.
