Spindle Cell Metaplastic Breast Carcinoma

Current Medical Imaging Formerly Current Medical Imaging Reviews, 2022
Introduction: Metaplastic breast carcinoma is an uncommon malignancy that constitutes < 5% of all breast cancers. There are 5 subtypes which are spindle cell, squamous cell, carcinosarcoma, matrix-producing and metaplastic with osteoclastic giant cells. Spindle cell carcinoma represents approximately <0.3% of invasive breast carcinomas.

Metaplastic carcinoma of the breast

Human Pathology, 2010
The purposes of this study were to investigate whether the biological characteristics or outcomes of patients with metaplastic carcinoma, invasive ductal carcinoma, or invasive lobular carcinoma of the breast differ; to determine whether the metaplastic carcinoma subtypes have similar malignant potentials; and to identify accurate predictors of outcome

Metaplastic carcinomas of the breast

Journal of Surgical Oncology, 1999
Metaplastic carcinomas of the breast are rare neoplasms. The purpose of the present study is to better characterize the clinical course, treatment, and prognostic factors of metaplastic breast carcinomas.Data of 14 patients with metaplastic breast carcinoma were retrospectively reviewed. The follow-up period ranged from 2 months to 10 years, 10 months (

Metaplastic carcinomas of the breast: V. Metaplastic carcinoma with osteoclastic giant cells

Human Pathology, 1990
The clinical and pathologic features of 29 examples of mammary metaplastic carcinoma with osteoclastic giant cells (OGC) in the stroma are reported. A bland spindle cell or sarcomatous component dominated these neoplasms, although infiltrating duct carcinoma was present in 23 cases, and intraductal carcinoma was present in six cases.

Metaplastic breast carcinoma with melanocytic differentiation

Pathology International, 2009
Metaplastic carcinoma of the breast is a rare heterogeneous malignancy, accounting for <1% of all invasive breast carcinomas, in which adenocarcinoma is found to coexist with an admixture of spindle, squamous, chondroid or bone‐forming neoplastic cells.

Metaplastic Carcinoma in an Ectopic Breast

Southern Medical Journal, 2002
We describe the case of an 81-year-old woman in whom a mass developed in the chest wall over 3 weeks. No previous mass in that area was reported. Physical examination was remarkable only for a 13 cm painless, purplish mass in the anterior chest wall. No masses were palpable in the anatomic breasts, and no lymphadenopathy was evident.

Metaplastic Breast Carcinoma Invading Chest Wall

Ultrastructural Pathology, 1995
Metaplastic breast carcinoma refers to a heterogeneous group of neoplasms in which the typical glandular growth pattern of the tumor undergoes metaplasia, either epithelial or stromal. A 59-year-old woman presented with a breast mass that recurred in 1 year and showed invasion of the chest wall.

Molecular alterations in metaplastic breast carcinoma

Journal of Clinical Pathology, 2013
Metaplastic carcinoma of the breast is a rare and heterogeneous subtype of breast carcinoma with a generally poor outcome, and few therapeutic options once disease recurs or progresses. Metaplastic carcinomas of the breast are usually of a larger size at diagnosis, with less frequent nodal metastasis compared with invasive ductal carcinoma no special ...

Metaplastic carcinoma of the breast

Cancer, 1998
Metaplastic carcinoma is a rare form of breast carcinoma that often is confused with other benign and malignant entities. The diagnosis can be difficult to establish on both a clinical and conventional histopathologic basis. One report recently described clinical and mammographic features dissimilar to the authors' experience but to the authors ...

Metaplastic carcinomas of the breast. I. Matrix-producing carcinoma

Human Pathology, 1989
The clinical and pathologic features of 26 examples of a histopathologically distinct form of metaplastic carcinoma of the breast are reported. All neoplasms had overt carcinoma with direct transition to a cartilaginous and/or osseous stromal matrix without an intervening spindle cell zone or osteoclastic giant cells.
