Abstract:
We report a case of giant mucinous carcinoma of the breast in a 55-year-old female who presented with left breast lump for two years. The patient did not seek any medical attention for two years. On exam, the lump measured 12 x 14 cm. Core needle biopsy showed invasive mucinous adenocarcinoma without ductal component. The patient underwent neo-adjuvant chemotherapy without any response. She underwent left modified radical mastectomy. All lymph nodes were negative. This was followed by adjuvant chemotherapy. Mucinous carcinoma is a rare type of breast cancer that carries a good prognosis compared to other types of breast cancers. In this report, we presented a giant mucinous carcinoma measuring 14 cm.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
