Primary squamous cell carcinoma of the breast: A rare case report

Breast Conservation Therapy for Primary Squamous Cell Carcinoma of the Breast in an Elderly Woman: A Case Report

This case report details a rare instance of primary squamous cell carcinoma (PSCC) of the breast in an octogenarian, emphasizing the unique diagnostic and treatment challenges posed by this malignancy in an elderly patient and adding to the scientific literature on PSCC managed with breast conservation therapy (BCT). An 80-year-old woman with medical comorbidities presented with a focal asymmetry in the right breast's retroareolar plane, detected during routine screening mammography. Diagnostic evaluations raised high suspicion for malignancy, confirmed as PSCC by ultrasound-guided biopsy. Histopathological analysis showed atypical keratinizing squamous epithelial nests and cysts. The patient underwent lumpectomy and re-excision of close surgical margins with a sentinel lymph node biopsy, which showed well-differentiated invasive squamous cell carcinoma with no residual carcinoma or nodal involvement. She was treated with adjuvant hypofractionated radiation therapy, experiencing minimal side effects. This case highlights the importance of considering individualized, nuanced approaches to adjuvant therapies in the treatment of PSCC in older patients. It demonstrates that BCT, coupled with carefully selected adjuvant therapy, can be a successful treatment strategy for PSCC in the elderly, contributing valuable insights into the management of this rare condition.

Primary squamous cell carcinoma of the breast: A case report and review of the literature

Primary squamous cell carcinoma (PSCC) of the breast, as a rare metaplastic breast cancer, currently has limited clinical data on its biological behavior, treatment and prognosis. At present, the optimal treatment of this tumor is still controversial. We reported a case of a 56-year-old woman with a mass on the right breast. She underwent a modified radical mastectomy and lymph node biopsy, which revealed that the tumor was a metaplastic squamous cell carcinoma with axillary lymph node metastasis, followed by traditional adjuvant chemotherapy and radiotherapy. The patient re-examined by PET/CT after two years in May 2017 and found a recurrence in the right chest wall, so resection of the recurring lesion was resected, then she was given postoperative adjuvant radiotherapy and chemotherapy. In August 2019, the patient re-examined by PET/CT, and there were pulmonary and mediastinal lymph node metastases. After 4 cycles of albumin paclitaxel plus cisplatin chemotherapy combined with nivolumab immunotherapy, the patient achieved complete response (CR), and then switched to nivolumab immune maintenance therapy. So far, no obvious metastasis has been seen. We believe that surgical treatment is necessary for PSCC of the breast;paclitaxel and cisplatin chemotherapy regimens and adjuvant radiotherapy are effective, but it may be resistant to radiotherapy; and immunotherapy may prolong the survival of patients with PSCC of the breast.

Squamous cell carcinoma of the breast: About a case

Squamous cell carcinoma of the breast is a rare metaplastic breast tumor whose histogenesis is controversial. Its prevalence is estimated between 0.06 % and 0.2 % of all breast neoplasms. The histogenesis remains obscure. The clinical aspects are not specific. Squamous cell carcinoma is characterized by a rapid evolution and by an uncodified treatment. The objective of our work, by reporting a new case of primary squamous cell carcinoma of the breast, is to specify through a literature review some characteristics of this particular form of breast cancer. Squamous cell carcinoma of the breast is a rare tumor belonging to the heterogeneous group of metaplastic carcinomas. The clinical and radiological presentations are not specific. The prognosis.

Primary squamous cell carcinoma of the breast: a case report and review of the literature

Primary squamous cell carcinoma of the breast is a rare tumor. The prognosis is poor, and hence there is a clinical trend to offer multi-modal treatment options of surgery, chemotherapy, and radiation therapy. There is no consensus on treatment options due to the paucity of available data. We are reporting the case of a 68-year-old lady who presented with a right breast mass. Upon core biopsy and further workup, she was noted to have primary squamous cell carcinoma of the breast. She was successfully treated with surgical therapy alone without disease recurrence at 36 months. Primary squamous cell carcinoma of the breast can be treated successfully with surgical therapy alone. The role of adjuvant chemotherapy, radiation therapy, and anti-estrogen therapy should be questioned as these modalities can lead to significant treatment-related morbidities and might not be contributing to disease-free interval or overall survival from this unusual tumor subtype.

Rare breast tumors: Review of the literature

Breast cancer tumors have different morphological phenotypes and specific histopathological types with particular prognostic and clinical characteristics. The treatment of rare malignant lesions is frequently controversial due to the absence of trials to determine the optimal managements. This review describes the spectrum of rare breast tumors indicating the clinical, epidemiological and treatment characteristics.
