Abstract
Giant fibroadenomas are uncommon benign lesions, defined as fibroadenomas of >5 cm in size and/or weighing more than 500 g. They can distort the shape of the breast and cause asymmetry, so they should be excised. Here, we report two cases of giant fibroadenoma, where wide local excision and reconstruction with lateral oncoplasty were done. Compared to all previous reports of patients with giant fibroadenoma, where the lump was excised either through a submammary incision or by round block technique depending on the location of the tumour, we used the lateral oncoplasty technique in both patients. Lateral oncoplasty is a new reconstructive option to maintain cosmesis and symmetry after the excision of giant fibroadenomas in the outer and central quadrants of the breast. It is a good option for reconstruction in cases where the defect is very large and facilities for conventional flap surgeries are not available.

Summary
Fibroadenomas in the breast are common benign lesions in women less than 30 years of age. Clinical examination showed a firm and mobile breast tumour on the outer quadrant of the right breast of approximately 10 cm in size, with dilated veins on overlying skin (Figures 1A, 2). Clinical examination showed a firm lump in the central quadrant of the left breast of approximately 12 cm in size, with dilated veins on overlying skin (Figure 4). Ultrasonography showed a large well-defined hypoechoic lobulated mass lesion with homogenous echo pattern and internal vascularity in the left-central quadrant measuring 13.8 x 10.5 cm. The patient was planned for wide local excision of left breast lump and reconstruction with lateral 2021 Jena et al Cureus 13(5): e15090. A skin crease incision was made in lateral axillary fold and flap was raised over the tumour with a thickness of 3-4 mm (Figure 5A).
