Adenosquamous carcinoma breast pathology outlines

Low-grade adenosquamous carcinoma of the breast is an uncommon neoplasm of uncertain pathogenesis, clinical behavior, and malignant potential. This report describes the clinical and pathologic features of 32 cases of low-grade adenosquamous carcinoma. All patients presented with palpable tumors ranging from 0.6 to 8.6 cm (mean, 2.8 cm) Low grade adenosquamous carcinoma May be considered as metaplastic carcinoma or as a distinct entity Most have a component of ductal carcinoma There are rare reports of metaplastic carcinoma associated with lobular, medullary, mucinous and tubular carcinoma Adenosquamous carcinoma of the breast (ASBC) is a rare variant of metaplastic breast cancer with both glandular as well as squamous differentiation. Their lack of distinct imaging characteristics, sometimes subtle histological characteristics and overlapping features with other benign lesions pose a diagnostic challenge Invasive cervical adenosquamous carcinoma is a relatively uncommon histologic subtype of cervical malignant neoplasms classified by the World Health Organization Classification of Tumors of Female.

Low-grade adenosquamous carcinoma (LGASC) is a low-grade variant of metaplastic carcinomas (MC) with favorable prognosis in the breast [ 4 ]. LGASC has been seldom reported to be associated with other neoplasms such as adenomyoepithelioma (AME) [ 5 ]. We report an extremely rare collision tumour of MFB and LGASC in the breast Rosen PP.

Adenosquamous breast carcinomas can be of 2 types - low-grade and high-grade. A majority of the tumors are low-grad Methods and results: Eight infiltrating epitheliosis, adjacent breast lesions (one usual ductal hyperplasia, one papilloma, one micropapillary ductal carcinoma in situ and one low-grade adenosquamous carcinoma), and corresponding normal breast tissue from each case were microdissected and subjected to massively parallel sequencing analysis. Adenosquamous carcinoma is a rare histology that disseminates to lymphatics, perineural and perivascular pathways, and lymph nodes in the peritoneum, much the same as is seen with standard adenocarcinoma of the pancreas.

Low-grade adenosquamous carcinoma is a rare and unique form of invasive mammary carcinoma. Though it is categorised as a variant of metaplastic carcinoma, it differs from its counterparts in this heterogeneous category by its relative clinical indolence, also reflected histologically in its low-grade cytomorphology CAP Approved Breast • Invasive Carcinoma Biopsy The routinely reported core data elements are bolded. 2 Surgical Pathology Cancer Case Summary Protocol posting date: February 2019 INVASIVE CARCINOMA OF THE BREAST: Biopsy Notes: This case summary is recommended for reporting biopsy specimens but is NOT REQUIRED for accreditation purposes Metaplastic breast carcinoma is a rare entity of breast cancer expressing epithelial and/or mesenchymal tissue within the same tumor. The aim of this study is to evaluate the clinicopathological features of metaplastic breast carcinoma and to confirm the triple negative, basal-like and/or luminal phenotype of this type of tumor by using immunohistochemical staining Metaplastic breast carcinoma.

In addition, low-grade adenosquamous carcinoma is a form of basal-like carcinoma, which would be expected to be ER-negative. 4 5 The present case was clearly ER-positive, albeit in a heterogeneous manner. In addition, the glandular structures in this case were positive for basal CKs

The morphologic range of metaplasic carcinomas is broad but some of the common subtypes are as follows: spindle cell carcinoma (fibromatosis-like; fibrosarcoma-like), sarcomatoid carcinoma/carcinosarcoma (chondrosarcoma, osteosarcoma, matrix producing carcinomas), metaplastic high-grade adenosquamous carcinoma, carcinoma with osteoclast-like giant cells, and metaplastic carcinoma with choriocarcinoma In breast pathology, medullary carcinoma partially reflected this aspect, but also syncytial arrangement of the tumor cells. In the 1st edition, the exaggerated lymphoid stroma was not a necessary prescription for this histological type, and there was a notion that the tumor could be of good prognosis even in the absence of a lymphoid stroma
