“…Osseous and chondroid differentiation may occur focally in 0.2% of carcinoma of breast, while osseous metaplasia is the rarest subtype [3]. Still there is controversy regarding classification of MBC [2].…”

Le carcinome métaplasique du sein est une entité rare et bien individualisé par l'OMS. Il représente moins de 1% des cancers invasifs du sein et constitue un groupe tumoral hétérogène soit purement épithélial soit à doublecontingent épithélial et mésenchymateuse. Le carcinome métaplasique avec différenciation osseuse extensive est très rare. Il représente 0.2% des carcinomes du sein. Nous rapportant un cas exceptionnel d'un carcinome métaplasique du sein avec différenciation osseuse extensive chez une patiente de 53 ans. A travers ce cas et une revue de la littérature, les caractéristiques anatomo-cliniques, radiologique, thérapeutiques et évolutives seront discutées.

“…Osseous and cartilaginous changes are frequently observed in the mesenchymal change (2). Osseous metaplasia of metaplastic breast cancer is relatively rare, accounting for <0.5% of all breast cancers (2–4). The treatment of metaplastic carcinoma of the breast is inconclusive due to the rarity of this subtype.…”

Metaplastic carcinoma of the breast with transformation from adenosquamous carcinoma to osteosarcomatoid and spindle cell morphology

et al. 2013

Metaplastic carcinoma of the breast refers to a heterogenous group of mammary carcinomas that contain a mixture of various cell types, including squamous cells, spindle cells and/or a mesenchymal component, such as bone or cartilage. To the best of our knowledge, the clinical course of a tumour that has undergone a transformation from one type of metaplastic carcinoma to another subtype has not previously been reported. The present study reports the five-year clinical and pathological course of a metaplastic breast carcinoma in a 55-year-old female, who was diagnosed with a sclerosing fibroadenomatous nodule with osseous metaplasia and focal atypia. A recurrent tumour was documented four years later, showing a predominant component of osteosarcoma with adenosquamous carcinoma. Upon pathological review of the initial mass, the diagnosis was changed to low-grade adenosquamous carcinoma. The patient was treated with breast conserving therapy. However, one year later, a recurrent metaplastic carcinoma with spindle cell morphology was documented and surgically removed by mastectomy. Subsequently, pulmonary invasion of the chest wall occurred and the patient eventually succumbed due to the invasive nature of the disease.
