Abstract
Pleomorphic carcinoma (PC) is an uncommon and high-grade form of breast carcinoma characterized by the presence of distinctive pleomorphic giant tumor cells exhibiting bizarre nuclei and atypical mitosis. In this study, we report three patients who presented with lesions composed of a proliferation of large pleomorphic cells with a predominance of multinucleated giant cells on a microscope. Immunohistochemical analysis revealed distinct immunologic profiles within the respective malignant components. Notably, this report aims to contribute valuable insights, adding to the understanding of this uncommon tumor, accompanied by a literature review. Despite its rarity, PC in the breast remains clinically relevant due to its distinctive morphological and pathological features. These unique attributes require specific considerations in both clinical presentation and management.

Abstract
Foci of necrosis are frequently seen in malignant tumours and may be due to a variety of causes. Different types of necrosis are given various names based upon their morphological features and presumed pathogenesis, such as coagulative, liquefactive and fibrinoid necrosis. Here, we propose the term 'granular necrosis' (GN) for a specific form of tumour necrosis characterised by the presence of well-defined necrotic foci being sharply demarcated from adjacent viable tumour. A constant feature is loss of architecture resulting in an amorphous necrotic mass containing granular nuclear and cytoplasmic debris, without an associated neutrophilic infiltrate. There is usually extensive karyorrhexis, which in larger tumours is more prominent at the periphery. These foci are often microscopic but may range up to several millimetres or larger in size. This distinctive form of necrosis has been erroneously given a variety of names in the literature including coagulative necrosis and microscopic necrosis, which on the basis of the aforementioned gross and microscopic findings is inappropriate. It is apparent that this is a specific form of necrosis, hence the descriptive term 'granular necrosis' that differentiates this form of necrosis from other types. The presence of GN is recognised as occurring in a variety of tumour types, being commonly seen in renal cell carcinoma, where it has been shown to have independent prognostic significance. In some epithelial and stromal tumours of the uterus, the presence of GN also has prognostic significance and is a defining feature for the differentiation of uterine leiomyoma and leiomyosarcoma. The pathogenesis of GN is unresolved. It does not show the features of apoptosis and in recent studies has been shown to have some of the molecular changes associated with necroptosis.

Abstract
Pleomorphic carcinoma is an aggressive neoplasm defined by the World Health Organization (WHO) as a poorly differentiated (squamous cell carcinoma or adenocarcinoma) or undifferentiated carcinoma in which at least 10% spindle and/or giant cells are identified, or as a carcinoma constituted purely of spindle and giant cells. Although this entity has initially been shown in the lung, it has been described also in extrapulmonary locations, with only one report for a colonic site. A 65-year-old woman developed a caecal tumour. Gross examination revealed an endophytic/ulcerative mass 7 cm in length. Microscopically, the tumour was a poorly differentiated adenocarcinoma with a pleomorphic component that occupied more than 10% of the specimen. The tumour shared these histopathological findings with pulmonary giant cell carcinoma but differed in other clinicopathological features such as a pushing growth pattern, stage pT3N1, and an uneventful outcome 24 months after operation. The pleomorphic component showed morphological and immunohistochemical features compatible with mitotic catastrophe, a non-apoptotic cell death occurring in cycling cells after aberrant mitosis. These features included multinucleation, micronucleation, atypical mitoses, foci of geographic necrosis, as well as immunohistochemical overexpression of p53 and Ki-67. The interpretation of the pleomorphic component as morphological expression of mitotic catastrophe may be useful in comprehending the pathogenesis of this rare neoplasm, and it may have practical implications as a potential cancer therapeutic target.

Abstract
A pleomorphic invasive ductal carcinoma developed in a patient with Huntington's disease. The tumour showed marked nuclear pleomorphism and contained large number of bizarre tumour giant cells and abundant abnormal mitoses. Tumour cells showed nuclear vesicles and inclusions similar to those described in nuclei of neural cells in patients with Huntington's disease. The case suggests that, in some patients, tumour morphology may reflect specific individual features.

Abstract
A mammary nodular lesion was recognized one month before the surgery in the right upper breast of a 55-year-old female. The fine needle aspiration cytology specimens contained many individual bizarre, multi-nucleated, and/or giant cells having hyperchromatic pleomorphic nuclei, prominent nucleoli, and relatively abundant cytoplasm, admixed with numerous mitotic figures in a hemorrhagic or inflammatory background. A small amount of sheet-like or three-dimensional clusters of malignant cells coexisted. We first interpreted it as high-grade malignancy, such as invasive carcinoma, not otherwise specified. A right breast-conserving surgery was performed, and gross examination revealed a cystic cavity-formed and solid tumor lesion, measuring 35 × 35 × 25 mm and looking gray-yellowish to -whitish. On microscopic examination, the tumor was composed of a diffuse proliferation of highly atypical cells devoid of adhesive characteristics, including many multi-nucleated giant bizarre cells, in a haphazard fashion with stromal invasion, alternating with sarcomatoid features of spindle tumor cells. The cystic cavity was surrounded by hemorrhagic and inflammatory granulation tissue and lined by mostly denuded but atypical tumor cells or bland-looking flattened epithelial cells. Immunohistochemically, these tumor cells are specifically positive for all epithelial markers. Therefore, we made a conclusive diagnosis of pleomorphic carcinoma of the breast with cyst formation. We should be aware that, owing to its characteristic findings, cytopathologists can diagnose correctly, based on careful cytological examination of adequate samplings.

Abstract
Pleomorphic ductal carcinoma of the breast is a rare variant included in the morphological group of infiltrating ductal carcinoma. The pleomorphic carcinoma is composed predominantly of epithelial and multinucleated tumor giant cells. We report here two cases presenting a lesion composed microscopically of a proliferation of large pleomorphic cells with a predominance of multinucleated giant cells. These lesions were negative for estrogen receptor, progesterone receptor and Her2-neu (triple-negative phenotype). Basal markers (cytokeratin 5/6, cytokeratin 17 and epidermal growth factor receptor [EGFR]) were present, accompanied by the presence of histiocyte marker CD163 in most neoplastic giant cells. High-grade pleomorphic breast carcinomas with the triple-negative phenotype and expression of basal markers might be included in the basal subtype. This is the first report about the co-expression of macrophage marker CD163, with tumor (P53) or epithelial markers (CAM5.2), as indicated by double immunohistochemistry in pleomorphic ductal carcinoma of the breast.

Abstract
The World Health Organization classification of tumors of the breast includes a rare variant of invasive ductal carcinoma termed pleomorphic carcinoma. This variant has marked nuclear pleomorphism (>6-fold variation in nuclear size by definition, but often>10-fold) and characteristically contains multinucleated tumor giant cells. Approximately one-third of the cases in the initial series contained a focal spindle cell metaplastic component. The tumors are reported to have an aggressive behavior, but because some contain a spindle cell metaplastic component, it is unclear whether the metaplastic component or other clinicopathologic features account for the poor clinical outcome. We identified 37 cases of pleomorphic carcinoma of the breast and evaluated the association between clinical outcome and multiple clinicopathologic features. Patients with invasive pleomorphic lobular carcinoma and those without at least a tissue biopsy before chemotherapy were excluded. Patients ranged in age from 23 to 78 years (median, 49 y). Tumor size was >5 cm in 12 cases and <5 cm in 22. A focal spindle cell component (<25% of the tumor) was present in 14 tumors (38%). Clinical follow-up was available for 36 patients (median, 17 mo). In multivariate analysis, when the 2 stage-IV patients were excluded, the presence of a spindle cell component and tumor size >5 cm were each independently associated with decreased overall survival. The actuarial 5-year overall survival for patients with and without a metaplastic spindle cell component was 38%+/-15% and 89%+/-7%, respectively. Poor clinical outcome, therefore, is associated with the subset of pleomorphic carcinomas with a spindle cell metaplastic component. As the morphologic features of pleomorphic carcinoma can be seen in primary tumors from other sites, it is important to recognize this tumor as a rare variant of invasive breast carcinoma.

Abstract
Pleomorphic lobular carcinoma of the breast is a recently described morphological variant of classic invasive lobular carcinoma with an aggressive behavior. Morphologically, pleomorphic lobular carcinoma elicits a similar pattern of infiltrative growth as invasive lobular carcinoma, yet neoplastic cells have marked nuclear atypia and pleomorphism. Pleomorphic lobular carcinoma and the in situ counterpart, pleomorphic lobular carcinoma in situ, are frequently hormone receptor (estrogen-, progesterone- and androgen-receptor)-positive and E-cadherin and β-catenin-negative, attaining to their lobular nature. Tumors can also be positive for HER2, p53, ki67 and GCDFP-15 and harbor frequent chromosomal alterations involving gains on 1q and 16p, losses on 11q and 16q, and genomic amplifications in the region of 8q24, 11q13, 12q13, 17q12 and 20q13. Recent gene-expression profiling classified pleomorphic lobular carcinoma as ‘molecular apocrine’ tumors reflecting the frequent apocrine differentiation of the tumors. In support for the aggressive biological features described for pleomorphic lobular carcinoma, accumulating clinical data demonstrate that it has an aggressive clinical course. It is now important to define the most appropriate management strategy for patients diagnosed with pleomorphic lobular carcinoma.

Abstract
An 83-year-old woman with long-standing chronic ischemic cardiac and obstructive pulmonary disease, presented with a painless tumor in her right breast. Microscopically the tumor consisted of micropapillary formations and loosely cohesive nests and strands of large, highly pleomorphic cells. Micropapillary formations were surrounded by peritumoral retraction clefting, and the papillae lacked a true fibrovascular core. Multinucleated giant and bizarre tumor cells were also present and numerous. Within the tumor a high-grade intraductal component with the same cell morphology and necrosis and mucin production was found. Micropapillary pattern occupied approximately 60% of the tumor mass, loosely cohesive nests and strands approximately 20% and an intraductal component was noted in approximately 20% of the tumor mass. On immunohistochemistry the tumor cells were positive for pan-cytokeratin, epithelial membrane antigen (EMA), S100 protein and E-cadherin while estrogen and progesterone receptors, HER2-neu and Bcl2 were negative. EMA staining was diffuse and observed in the outer and inner margins of neoplastic nests. The diagnosis of pleomorphic breast carcinoma with predominant micropapillary features was established. In summary, micropapillary carcinoma can be distinguished from other types of breast carcinoma with micropapillary growth pattern on the basis of reverse cell polarity, which is easily confirmed on immunohistochemistry.

Abstract
Herein is presented the case of an esophageal pleomorphic giant cell carcinoma combined with small cell carcinoma (SCC). The patient, a 77-year-old man, initially presented with dysphagia and hoarseness, and endoscopy indicated a large esophageal tumor. Despite chemoradiation therapy, the patient died from widespread local extension of the tumor and distant metastases approximately 8 months after onset of the symptoms. Histologically, the primary tumor was composed of pleomorphic tumor components, SCC components, and a tiny focus of squamous cell carcinoma. The pleomorphic tumor cells, consisting of solid sheets of poorly cohesive epithelioid cells and numerous multinucleated giant cells with abundant eosinophilic cytoplasm, were immunohistochemically positive for vimentin and desmin, with scattered positivity for epithelial membrane antigen (EMA) and neuron-specific enolase (NSE), but negative for myoglobin. These findings were histopathologically compatible with pleomorphic giant cell carcinoma occurring at other sites such as the lung. SCC cells, morphologically similar to their pulmonary counterpart, were positive for EMA and some neuroendocrine markers such as chromogranin A and NSE, and occasionally positive for vimentin and desmin. Esophageal pleomorphic giant cell carcinoma can occur in close association with SCC, and should be included in the differential diagnosis of esophageal tumors showing pleomorphism.

Abstract
BACKGROUND Invasive ductal carcinoma of the breast is a heterogeneous collection of divergent types of carcinomas. Some subtypes have been characterized by histologic observations. This study describes a distinctive subset recognized through cytomorphologic examination of breast carcinoma specimens obtained by fine-needle aspiration biopsies (FNAB). Identification of this subset is established further by analyses of its clinical and immunologic characteristics. METHODS One hundred patients underwent FNAB and were diagnosed with breast ductal carcinoma. These diagnoses were followed by surgical resections and histologic evaluation of tumors. Immunohistochemical analyses of estrogen receptor, progesterone receptor, Her2/neu, p53 protein, and Ki-67 were performed. Patient's age, race, and family history of breast carcinoma were obtained. The objective of the study is to identify a cytomorphologically distinctive, clinically relevant, subset of breast carcinomas. RESULTS A subset carcinoma was recognized by cytomorphologic examination of Pap-stained FNAB slides. This subset consisted of seven patients with a median age of 37 years. At the time of surgical resection, all patients had axillary lymph node metastases. Six of seven patients had distant metastases. Immunohistochemical studies revealed that all tumors are positive for p53 protein and negative for estrogen and progesterone receptors. CONCLUSION This study presented a unique subset of breast ductal carcinomas that involved young patients and had aggressive growth behavior. These tumors expressed p53 protein but not estrogen and progesterone receptors.

Abstract
Keratin expression in human tissues and neoplasms Keratin filaments constitute type I and type II intermediate filaments (IFs), with at least 20 subtypes named keratin 1-20. Since certain keratin subtypes are only expressed in some normal human tissues but not others, and vice versa, various tissues have been subclassified according to the pattern of keratin staining. Simple epithelia generally express the simple epithelial keratins 7, 18, 19, and 20, while complex epithelia express complex epithelial keratins 5/6, 10, 14, and 15. When an epithelium undergoes malignant transformation, its keratin profile usually remains constant. The constitution and expression patterns of keratin filaments in human epithelial neoplasms are complex and often distinctive. In this article, we first briefly review the molecular and cell biology of keratin filaments. We then focus on the expression patterns of keratin filaments in various human neoplasms.

Abstract
CONTEXT Estrogen receptor (ER)-negative breast carcinomas are a heterogeneous group of breast cancers that are generally thought to be aggressive. OBJECTIVE To determine the morphologic and immunohistochemical spectrum of a consecutive series of ER-negative breast carcinomas, in an attempt to understand the pathogenesis and behavior of these lesions. DESIGN Seventy-four consecutive cases of ER-negative invasive carcinomas were studied. Hematoxylin-eosin-stained sections were reviewed, and new sections were stained for c-erbB-2, p53, vimentin, and androgen and prolactin receptors. The findings were correlated with the axillary lymph node status as a measure of tumor aggressiveness. SETTING The histopathology department of a tertiary referral teaching hospital. RESULTS The tumors included 50 (68%) invasive ductal carcinomas, 21 (28%) medullary/atypical medullary carcinomas, and 1 each of invasive lobular, apocrine, and papillary carcinoma. Some of the invasive ductal cases had distinctive features that are described in this report. Maximum tumor diameter varied between 5 and 100 mm. Sixty tumors (81%) were grade 3, 13 (18%) were grade 2, and 1 (1%) was grade 1. Of the 60 cases in which the axillary node status was known, 34 (57%) had metastases, and 26 did not. Tumors associated with positive nodes were significantly larger than those associated with negative nodes (37.2 vs 17.8 mm, P <.001). A higher percentage of node-negative tumors were c-erbB-2 positive (42% vs 21%, P <.05). There were no differences between the 2 groups with regard to histologic type, tumor grade, or the expression of p53, vimentin, or androgen or prolactin receptors. CONCLUSIONS Many ER-negative breast carcinomas have distinctive microscopic features. Not all ER-negative tumors are aggressive, as judged by the absence of lymph node metastases in 43% of cases in this series. Tumor size is the most important indicator for the likelihood of the presence of lymph node metastases. The wide range of tumor sizes encountered in this series suggests that the ER status of a tumor is determined early in its natural history and supports the existence of 2 separate pathways for the development of ER-negative and ER-positive breast carcinomas.
