Gestational gigantomastia on a Saudi woman: A case report on surgical removal and reconstruction and management of complications, KFSH&RC

INTRODUCTION: Gestational gigantomastia (GG) is a rare condition manifesting as a fast and excessive growth of the breasts in pregnant women. Its etiology is still unclear, with theories ranging from hormonal imbalances, unregulated immune response, to hypersensitivity. Medical interventions are mainly surgical in nature, though some pharmacological medications are of debatable efficacy. CASE PRESENTATION: A 33-year old Saudi gravida 3 para 2 presents continuous breast enlargement since the start of her pregnancy. She complains of skin ulcerations and discharge which was initially treated conservatively with topical antibiotics. Days after she came back with worsening GG symptoms, and was admitted for bilateral skin sparing mastectomy and reconstruction, and successfully recovered. The patient came back with problems concerning the surgical implant and wound infection. Emergency operation was performed for implant removal and wound treatment. Labor induction was performed by the OB-GYN on her 39 week. The patient opted for autogenous reconstruction by bilateral latissimus dorsi flap months after delivery. After treatment of minor surgical complications, the patient successfully recovered. DISCUSSION: Surgery is one of the most effective interventions for GG. Total mastectomy is preferred due to lesser risk of recurrence in subsequent pregnancies. Reduction mammoplasty offers the breastfeeding option if conducted before the delivery, but poses higher risk of recurrence in future pregnancies. CONCLUSION: The patient’s gestational gigantomastia condition was complicated by several ulcerations and infections. Surgery was conducted alongside antibiotic treatment. This report also highlights the importance of follow ups in managing complications.
