A 52-year-old lady was seen in the breast clinic after an 8mmlesion was found in her left breast on screening mammogram. Clinical\nexamination was normal. The left breast mammogram showed an 8mm rounded density posteriorly in the inner half of breast and\nultrasound also showed a 7 mm, well-defined ovoid echogenic lesion (R3, U3). Biopsy confirmed the lesion was fibro-fatty tissue\ncontaining a diffuse infiltrate of lymphoid cells macroscopically (B3/4)--- findings in line with a diagnosis of a myofibroblastoma.\nA myofibroblastoma is a rare benign mesenchymal tumour comprising of spindle cells. Most breast myofibroblastomas\ndescribed in the literature have been excised by wide local excision. In this patientâ??s case, a vacuum-assisted technique was\ndiscussed and suggested at the multidisciplinary meeting. It was excised using ultrasound-guided Vacora® breast biopsy system.\nThe lesion was completely excised with the encore biopsy measuring 24 *17mm. This is the first documented case of such a\ntechnique for the excision of a breast myofibroblastoma. There still is uncertainty about breast myofibroblastomas, their\naetiology, associations, and how they are best investigated. Regarding management, vacuum-assisted technique, being less\ninvasive and cheaper than local excisions, is adequate for small lesions.
