Pregnancy tumor occuring twice in the same individual: Report of a case and hormone receptors study

A case of 2 pregnancy tumors in the same individual and at the same site within 2 years, during 2 consecutive pregnancies, despite complete eradication of the first lesion, is described. A 27-year-old woman at 32 weeks gestation was referred for gingival swelling. Gingival enlargement was pronounced on her maxillary right side, and a hemangioma was present on the lip adjacent to this mass. Despite preventive periodontal treatment the lesion continued to grow, interfering with speech and mastication, and became painful; it was therefore removed surgically. Sixteen months later, during a subsequent pregnancy, the woman returned at 20 weeks gestation for treatment of a recurrent lesion at the same site, and the lesion was excised. The roles of female sex hormones, multiplicity of vascularity, and local irritants in the development of pregnancy tumors are examined.
