| Yhteenveto: | A 57-year-old female, a housewife, presented with complaints of a gradually increasing lump in the left breast for two months. There was no history of nipple discharge, weight loss, or loss of appetite. Additionally, there was no family history of breast carcinoma. On local examination and palpation of the left breast, a palpable lump measuring 6x6 cm was found. The lump involved the retroareolar and lower outer quadrant, and it had a firm consistency and was mobile. The overlying skin was pinchable. The nipple-areolar complex and left axilla were normal. The lump was non tender. The patient was then referred for mammography and ultrasound of the breast. The ultrasound revealed a hypo to isoechoic lesion measuring 5.3x2.7 cm with microlobulations and minimal peripheral vascularity in the lower outer quadrant of the left breast [Table/Fig-1a,b]. No significant left axillary lymph nodes were detected. The mammography showed a relatively high-density lobulated well-defined mass in the retroareolar and lower outer quadrant of the left breast. No microcalcifications or surrounding architectural distortion were detected [Table/Fig-2a,b]. Radiologically, a Breast-imaging Reporting and Data System (BI-RADS) 3 or 4a lesion was considered since the lesion had well-defined lobulated margins. Magnetic Resonance Imaging (MRI) was performed, which showed a well-defined lobulated mass without diffusion restriction, mimicking a benign lesion [Table/Fig-3a,b]. The patient then underwent fine needle aspiration cytology, which revealed Mucinous Carcinoma (MC) of the breast. Subsequently, the patient underwent a modified radical mastectomy after a metastatic work-up. There was no evidence of distant metastasis on chest X-ray, abdominal ultrasound, and bone scan. The patient was not able to afford Positron Emission Tomography-computed Tomography (PET-CT). The resected specimen showed features of MC of the breast with pathological staging of pT1bN0Mx. Two axillary lymph nodes were resected, and they were free of tumour. The tumour was unifocal with a histological grade of 2. The cancer was both Estrogen Receptor (ER) and Progesterone Receptor (PR) positive, Human Epidermal Growth Factor Receptor (HER2) 2 negative. The mucin content was over 90%, suggesting the pure mucinous variety rather than the mixed variety. The patient was then referred to a medical oncologist for chemotherapy. The patient is presently doing well after six months of follow-up. |
