Breast cancer cutaneous metastasis at core needle biopsy site.

Concordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

Needle Core Biopsy Should Replace Fine Needle Aspiration Cytology in Breast Lesions Diagnosis

Cutaneous Metastasis from Breast Tumour Seeding in Percutaneous Needle Biopsy.

tissues. 0.7–0.9% of patients with a malignant tumour at any site can develop a cutaneous or subcutaneous metastasis after percutaneous procedures [2]. The duration between the onset of tumour seeding and the previous percutaneous needle biopsy has been shown to vary widely. Clinically, tumour deposits are observed as painful cutaneous or subcutaneous nodules, typically round or oval, with well...

The Core Needle and Surgical Biopsy Concordance to Detect Estrogen, Progesterone, and Her-2 Receptors in Breast Cancer: A Comparative Study

Background &Objectives;: Evaluation of estrogen receptor (ER), progesterone receptor (PR), and (human epidermal growth factor receptor-2) Her-2 on core needle biopsies (CNBs) is increasingly in use to diagnosis early breast cancer, but its concordance with surgical excision (SE) is not well documented. Methods: The study ...

Skeletal Muscle Metastases from Breast Cancer: Two Case Reports

The skeletal muscle is an unusual site for metastasis from breast cancer. We present two cases of breast cancer that relapsed as skeletal muscle metastasis without other distant organ metastasis. We performed the core needle biopsy of metastatic sites and confirmed discordance in estrogen receptor, progesterone receptors, and human epidermal growth factor receptor 2 expression between primary b...
