To the Editor.—
Ulcerating, small papular granulomas (Figure) were examined in the mastectomy scars of three patients.These 3- to 6-mm papules were soft, and removal of the crust resulted in brisk capillary bleeding. About some of the papules there was a collarette of intact skin. In all cases, biopsy specimens showed various stages of granulation tissue. Polariscopic examination for refractile material was negative. No other foreign bodies were identified.These granulomas developed four to 24 months after surgery. The patients said the lesions bled from time to time; at other times, they would heal over and be asymptomatic. The type of carcinoma and the operation did not appear to be significant. None of the patients had received radiotherapy. Curettage after biopsy was curative. These granulomas should not be confused with recurrent carcinoma.
