Background: Large recurrent phyllodes breast tumors are often malignant. Therefore, when taking the surgical decision, a simple mastectomy and immediate reconstruction must be considered. Case presentation: The patient, aged 40 years, with a benign phyllodes tumor in the left breast, having a recurrence 2 years after, with 4–7 cm conglomerate tumor masses, was subjected to skin-reducing mastectomy, breast reconstruction with a silicone mammary implant in the left breast, and symmetrization of the right breast. Discussion and conclusions: In the case of patients with breast hypertrophy and gigantomastia (cup size D–F), skin-reducing mastectomy and immediate reconstruction with an implant can be the option. It is important for the resection specimen to include the skin tissue above the tumor. After 14 months of follow-up, there was no recurrence of the lesions on a clinical examination, ultrasonography, or MRI.

Glycosaminoglycan (GAG) is a chain-like disaccharide that is linked to a polypeptide core to connect two collagen fibrils/fibers and provide the intermolecular force in a Collagen-GAG matrix which can be a valuable treatment of post-burn contractures and hypertrophic scars, which remain a challenge to reconstructive surgery. The face and neck contractures are the most difficult sites to treat. This article is meant to discuss our clinical experience in using collagen-glycosaminoglycan biodegradable matrix (Integra® Integra Lifesciences Corporation, Plainsboro, NJ, USA) to reconstruct defects created by excision of contracted areas from the neck and lower face areas. Between 2009 and 2011, we had 11 patients that underwent Integra reconstructive procedures. The mean follow-up period was 18 months. For all the patients, the intake of the Integra dermal regeneration template was 100%, even if one patient developed a minor infection treated with appropriate antibiotics. The patients are very satisfied with the result. A minor problem was a small difference in skin color, but this inconvenience was compensated by good skin elasticity.
