INTRODUCTION: Breast cancer diagnosed within 10 years of parturition is named postpartum breast which a highly metastatic tumor with poor prognosis. CASE REPORT: A 31-year-old female presented fever and painful mass in the left breast. She had undergone C-section 6 months ago her second child. biopsy was performed showed estrogen receptor-negative, progesterone human epidermal growth factor rec...

BACKGROUND Mammary metaplastic carcinoma encompasses epithelial-only carcinoma (high-grade adenosquamous carcinoma or pure squamous cell carcinoma), biphasic epithelial and sarcomatoid carcinoma and monophasic spindle cell carcinoma. AIM To evaluate the clinicopathological features of a large series of 34 metaplastic carcinomas. METHODS 10 epithelial-only, 14 biphasic and 10 monophasic meta...

The histogenesis of ovarian malignant mixed mesodermal tumours, which includes the concept of metaplastic carcinoma, is controversial. Four such tumours were examined for evidence of metaplastic transition from carcinoma to sarcoma using morphology and reticulin stains. Consecutive sections were stained immunohistochemically using cytokeratin and vimentin to determine whether cells at the inter...

ma. It accounts for less than 5% of breast cancers (1-3), and it may have a poorer prognosis than most other breast malignancies (4, 5). Some authors have reported a metaplastic carcinoma of the breast with the mammographic and sonographic features (3, 6), however, typical magnetic resonance imaging (MRI) findings are unknown. The MRI findings of a metaplastic carcinoma of the breast were evalu...

BACKGROUND Breast metaplastic squamous cell carcinoma (SCC) is a rare primary breast carcinoma, and overexpression of HER2 in this carcinoma is extremely uncommon. CASE REPORT We presented a case of a 48-year-old Asian female with breast metaplastic SCC. Fine needle aspiration biopsy (FNAB) and core needle biopsy (CNB) of the lesion were taken prior to surgical resection. FNAB smears demonstrat...

The metaplastic breast carcinoma is a rare malignancy with an incidence of 5% of all breast tumors [1, 2]. It originates from a change in the differentiation of epithelial metaplastic breast tissue cells to squamous cell, spindle cell and/or mesenchymal appearance [3]. The metaplastic component can be benign or malignant. The differentiation degree and proportion of the elements shown in these ...

Metaplastic carcinoma of breast (MBC) is a rare type of invasive breast carcinoma. It poses diagnostic challenge due to its varied histology and diverse differentiation. These are heterogenous group of tumors in which part or whole of the carcinomatous component is transformed into a metaplastic mesenchymal component and runs an aggressive clinical course. We present two cases of metaplastic ca...

ma that comprises less than 5% of all breast malignancies (1, 2). These tumors are ductal carcinomas that can undergo a variety of metaplastic changes including squamous cell, spindle cell, and heterologous mesenchymal growth (3, 4). The most common of these metaplastic changes is squamous metaplasia, and its incidence varies from 0.5 to 2.0% (5). The microscopic criteria for the diagnosis of t...

Patient: Female, 33 Final Diagnosis: Matrix-producing metaplastic breast carcinoma Symptoms: - Medication: - Clinical Procedure: Operative Specialty: Oncology Objective: Rare disease. BACKGROUND Metaplastic breast carcinomas are ductal carcinomas that undergo metaplasia into non-glandular growth patterns. They ...

BACKGROUND: Metaplastic carcinoma of the breast is a rare but distinct entity within the group of undifferentiated invasive carcinomas. This entity accounts for less than 0.5% of all breast cancers and contains elements of epithelial (ductal), mesenchymal, and intermediate forms of differentiation. Of these metaplastic carcinomas, there have been reports of chondroid, squamous, osseous, and spi...
