An overview of invasive micropapillary carcinoma of the breast: past, present, and future.

Invasive micropapillary carcinoma of the breast (IMPC) exhibits a unique micropapillary structure and "inside-out" growth pattern. Despite its extremely low incidence, IMPC has attracted considerable attention owing to its poor prognosis. Since Siriaunkgul and Tavassoli first proposed the term IMPC in 1993 to describe its morphological characteristics, with tumor cell clusters arranged in a pseudopapillary structure within the glandular cavity, its diagnostic rate has substantially increased.

UA influences the progression of breast cancer via the AhR/p27/cyclin E pathway.

Reconstruction of the chest wall in locally advanced breast cancer with multi-disciplinary cooperation: a case report of mesh repair plus TRAM combined with DIEP chest wall reconstruction.

Locally advanced breast cancer, which is defined as a malignant breast tumor that invades or adheres to the surrounding tissue, is characterized by the invasion of the chest wall and the skin surface by the tumor. Multiple lymph nodes are invaded and fuse into a mass, causing extensive axillary lymph node metastasis. However, locally advanced breast cancer does not exhibit distant metastasis.

Modified radical mastectomy for anterior thoracic nerve and intercostobrachial nerve protection (case report).

Modified breast cancer radical mastectomy is a more common operating method in breast surgery. Traditional modified radical mastectomy focuses on protecting the long thoracic nerve and thoracodorsal nerve while ignoring the protection of the anterior thoracic nerve and intercostobrachial nerve protection, which leads often to patients with upper medial arm numbness, acid swelling, pain, chest atrophy, and other problems. In the modified radical mastectomy of breast cancer, in this case, the author used an elaborative operation to protect the anterior thoracic nerve and intercostobrachial nerve and thoroughly dissected the third-level lymph nodes through the axillary approach.
