RESUMO
It is unusual to find a breast tumour in a keloid, as the management of both is distinct. In this case, a young woman was operated on 4 years ago, for a right chest wall swelling, situated near the inframammary fold. The histopathological report revealed a granuloma, for which anti-tuberculosis treatment was given. However, the swelling recurred and progressed in size over the next 3 years. Then, she consulted the dermatology department, where the swelling was managed as a keloid. There was no remission. Consequently, the possibility of a breast tumour was suspected, and the patient was referred to breast services (subdivision of the surgery department).Triple assessment of the breast lump was suggestive of a phyllodes tumour (PT). Surgical excision of the tumour was done, which showed a malignant PT. Radiotherapy was given and delayed breast reconstruction was planned.
