Abstract Primary breast lymphoma accounts for 0,04-0,5% of breast tumours and <1% of non‑Hodgkin lymphomas. Its main differential diagnosis is breast carcinoma. Case 1: female, 51 years old, pre-menopause, presented with left axillary adenomegaly with suspicious ultrasound characteristics, breasts without alterations. Ultrasound-guided microbiopsy and excisional biopsy revealed reactive lymphadenitis. Two months later, the patient presents with fever and a lump with fluctuation in the left breast. Surgical exploration was performed for suspected breast abscess and histopathological evaluation diagnosed anaplastic large T-cell lymphoma, ALK-positive. Case 2: female, 89 years old, suspicious left breast lump. Ultrasound-guided breast microbiopsy revealed follicular lymphoma.
