Abstract
BACKGROUND Our study investigates the prognostic significance of spindle cell histology on overall survival (OS) of conventional head and neck squamous cell carcinoma (HNSCC). METHODS The 2004 to 2017 National Cancer Database was queried for patients with head and neck spindle cell carcinoma (HNSpCC) (n = 1572) or HNSCC (n = 242 697) of the oral cavity, major salivary glands, sinonasal tract, oropharynx, hypopharynx, and larynx treated with curative intent. RESULTS Patients with HNSpCC presented more frequently with higher-grade tumors and cN0 disease than those with HNSCC (p < 0.001). In the oral cavity, the HR for death for SpCC compared with SCC was 1.33 (p < 0.001). In the oropharynx, the HR for death for SpCC compared with SCC was 1.47 (p = 0.028). CONCLUSIONS After adjusting for patient, tumor, and treatment characteristics, SpCC histology had an independent adverse prognostic effect on OS in the oral cavity and oropharynx. SpCC histology does not necessarily portend poorer survival in all HNSCC. LEVEL OF EVIDENCE: 4

Abstract
Immunohistochemistry represents an indispensable complement to an epidemiology and morphology-driven approach to tumor diagnosis and site of origin assignment. This review reflects the state of my current practice, based on 15-years' experience in Pathology and a deep-dive into the literature, always striving to be better equipped to answer the age old questions, "What is it, and where is it from?" The tables and figures in this manuscript are the ones I "pull up on the computer" when I am teaching at the microscope and turn to myself when I am (frequently) stuck. This field is so exciting because I firmly believe that, through the application of next-generation immunohistochemistry, we can provide better answers than ever before. Specific topics covered in this review include (1) broad tumor classification and associated screening markers; (2) the role of cancer epidemiology in determining pretest probability; (3) broad-spectrum epithelial markers; (4) noncanonical expression of broad tumor class screening markers; (5) a morphologic pattern-based approach to poorly to undifferentiated malignant neoplasms; (6) a morphologic and immunohistochemical approach to define 4 main carcinoma types; (7) CK7/CK20 coordinate expression; (8) added value of semiquantitative immunohistochemical stain assessment; algorithmic immunohistochemical approaches to (9) "garden variety" adenocarcinomas presenting in the liver, (10) large polygonal cell adenocarcinomas, (11) the distinction of primary surface ovarian epithelial tumors with mucinous features from metastasis, (12) tumors presenting at alternative anatomic sites, (13) squamous cell carcinoma versus urothelial carcinoma, and neuroendocrine neoplasms, including (14) the distinction of pheochromocytoma/paraganglioma from well-differentiated neuroendocrine tumor, site of origin assignment in (15) well-differentiated neuroendocrine tumor and (16) poorly differentiated neuroendocrine carcinoma, and (17) the distinction of well-differentiated neuroendocrine tumor G3 from poorly differentiated neuroendocrine carcinoma; it concludes with (18) a discussion of diagnostic considerations in the broad-spectrum keratin/CD45/S-100-"triple-negative" neoplasm.

Abstract
Sarcomatoid carcinomas, also known as spindle cell carcinomas (SPCCs), are rare carcinomas, predominantly developing in the lung. They have lots of features of sarcoma in their histological features. The standard laryngeal carcinoma classification is based on tumor size, lymph node affection, and metastasis (TNM), it is the classification scheme of the American Joint Committee on Cancer Staging (AJCC), and it is used in the same way for stage spindle cell carcinoma (SPCC). We present a case report of a young female along with a literature review of sarcomatoid carcinoma of the larynx.

Abstract
Although the majority of laryngeal malignancies are the conventional squamous cell carcinomas (SCC), a wide variety of malignant epithelial tumors can affect the larynx. Current treatment guidelines are designed to guide clinicians in management of conventional laryngeal SCC. Less is known about the biological behavior and responsiveness to therapy and overall outcomes of other malignant epithelial lesions. Because a spectrum of disease biology is represented by these rare phenotypes, an understanding of the basic biology can help direct management to optimize clinical outcome in this group of patients. This review provides a critical analysis of literature relating to the diagnosis, management, and outcome of patients with non-conventional squamous malignant epithelial neoplasms of the larynx. Particular attention is paid to features which are at variance with the conventional SCC and how these impact on management of these rare tumors.

Abstract
Spindle cell carcinoma (SPCC) is a rare, malignant variant of squamous cell carcinoma (SCC), which shows biphasic proliferation of the conventional SCC component and malignant spindle shape cells with sarcomatous appearance. We present two cases of SPCC of the true vocal fold that presented as a benign appearing subepithelial mass. We discuss the patient presentation, voice assessment, surgical treatment, and a review of the literature.

Abstract
Sarcomatoid carcinomas are biphasic tumors proven to be monoclonal dedifferentiated forms of conventional squamous carcinomas. This study evaluates their clinicopathologic characteristics in head and neck mucosal sites and the problems in distinguishing them from other spindle cell tumors. A total of 103 cases with a confirmed diagnosis of sarcomatoid carcinoma accessioned in the pathology department of a tertiary referral cancer centre over a period of 7 years (2004-2010) were studied. An algorithm used for their diagnosis is presented. Ages of the patients were 22-90 years (median 53 years), and male:female ratio was 3.7:1. Site distribution was oral cavity (n = 65, 63.1%), larynx (18, 17.5%), oropharynx/hypopharynx (12, 10.7%), maxilla (6, 5.8%) and metastatic nodes (2, 1.9%). A large number of patients (95%) presented with a mass lesion of less than 1 year duration. Histopathologically, epithelial differentiation was evident on morphology in 48 (46.6%) cases, only on IHC in 34 (33%) cases, and in 21 (20.4%) no epithelial differentiation was seen. Typically, tumors were polypoidal (92, 89.3%) and ulcerated (95, 92.2%) with cells arranged predominantly in fascicles (59, 57.3%) or storiform pattern (17, 16.5%) amidst collagenous (50, 48.5%) or myxoid matrix (35, 34%). Anaplasia (2+/3+) and mitosis >10 per 10 HPF were noted in 96 (93.2%) cases. IHC was done in 82 cases; 55 (66.7%) showed positivity for epithelial markers with aberrant expression of mesenchymal markers in 43 (41.7%). Diagnosis of sarcomatoid squamous carcinoma is challenging because of overlapping histopathological features with other spindle cell tumors. Understanding their clinicopathologic characteristics facilitates their diagnosis and appropriate clinical management.

Abstract
Sarcomatoid carcinoma of the upper respiratory tract is a phenotypically complex neoplasm that has triggered much thoughtful discussion regarding histogenic origin and morphologic classification. In particular, its putative epithelial lineage and distinction from a pseudosarcomatous reaction are sometimes questioned. Little is known about the genetic alterations underlying sarcomatoid carcinoma. Although about 45% of conventional squamous cell carcinomas of the upper respiratory tract harbor p53 mutations, the p53 status of sarcomatoid carcinomas is not well established. p53 immunohistochemical analysis using the monoclonal antibody D07 was performed on 23 sarcomatoid carcinomas of the upper respiratory tract. Twenty tumors were biphasic, having dual epithelial and spindled components. In four of these biphasic tumors, the epithelial and spindled components were separately analyzed for p53 gene mutations by sequence analysis. p53 immunohistochemistry was also performed on 19 cases of postradiation stromal atypia. Strong and diffuse p53 staining was detected in 18 (78%) of the 23 sarcomatoid carcinomas. When the spindled component was compared with its corresponding epithelial component, identical patterns of p53 protein expression were noted in 19 (95%) of the 20 biphasic tumors. Weak p53 staining was observed in one (5%) of the 19 cases of postradiation stromal atypia. In the four biphasic tumors evaluated by DNA sequence analysis, p53 status was always the same in the paired epithelial and spindle cell components. These findings help further dispel the notion that sarcomatoid carcinoma represents a reactive spindle cell proliferation (pseudosarcoma) or a collision between a carcinoma and a sarcoma (collision tumor). Instead, the epithelial and spindled components share a common pathway of tumorigenesis despite their conspicuous divergence at the phenotypic level.

Abstract
Laryngeal spindle cell (sarcomatoid) carcinomas are uncommon tumors, frequently misdiagnosed as reactive lesions or mesenchymal malignancies. The records of 187 patients with tumors diagnosed as laryngeal spindle cell (sarcomatoid) carcinoma were retrieved from the files of the Otorhinolaryngic Tumor Registry of the Armed Forces Institute of Pathology. There were 174 men and 13 women, 35-92 years of age (average, 65.6 years). Nearly all patients experienced hoarseness (n = 165 [88%] patients) for a mean duration of 11.0 months. Patients admitted to smoking (n = 162 [87%] patients) and/or alcohol use (n = 90 [48%] patients). Most tumors were glottic (n = 132 [71%]), T1 (n = 111 [59%]), 1 and polypoid (n = 185 [99%]), with a mean tumor size of 1.8 cm. Histologically, squamous cell carcinoma (n = 157 [84%]) was noted, ulcerated, and blended with the spindle cell component, which was most frequently arranged in a storiform pattern (n = 92 [49%] tumors). Foci of benign or malignant cartilage and/or bone (n = 13 [7%]) were noted in the spindle cell component. All patients were treated with surgery (n = 90 [48%] patients) or surgery with radiation (n = 97 [52%] patients). Recurrences developed in 85 (45%) patients. Overall, T1 glottic tumors managed by complete surgical eradication had the best outcome (mean follow-up, 7.8 years).

Abstract
This paper discusses the indications for neck dissection in those patients with laryngeal tumours which prove to be, on pathologic examination, not conventional squamous carcinomas but rather fall into the category either of one of the uncommon histological subtypes of carcinoma, or another type of unusual histological variant of laryngeal malignancy, a mesenchymal tumour. It appears as though these unusual laryngeal malignancies may manifest both biological behaviours and propensities to metastasize to regional lymph nodes that differ from those of the more commonly encountered conventional squamous carcinomas of the larynx. This heterogeneous group of tumours accounts for about 10 per cent of all malignant tumours of the larynx.

Abstract
Spindle cell carcinoma (SpCC) is uncommon, with a predilection for the upper aerodigestive tract. Its histogenesis has not been resolved, although most authors support the sarcomatoid carcinoma concept. Ploidy analysis and proliferation indices have not been reported for laryngeal SpCCs. The authors examined the pathological and clinical features of 26 patients (25 men, 1 woman; mean age, 64 years) with laryngeal SpCC treated at the Mayo Clinic from 1960 to 1990. Twenty-three tumors were examined with digital image analysis for DNA content of the spindle cell population (13 tumors had a sufficient squamous component to be analyzed separately). The glottis was involved most frequently (19 patients); 21 tumors were grossly polypoid. Twenty-three tumors were biphasic, and three were monophasic. Overall, 17 tumors (65%) showed keratin positivity in the spindle cell component. Polyclonal antikeratin (15 positive cases), 34betaE12 (15 positive), and AE1/AE3 (12 positive) were the most sensitive markers. Spindle cells were diploid in 5 tumors (22%) and nondiploid in 18 (78%); conventional squamous cell carcinoma was diploid in 4 cases and nondiploid in 9. DNA ploidy results were concordant between the two populations in 11 of 13 tumors (85%). Mean percent MIB-1 staining was 31% in the sarcomatoid component and 45% in the squamous component. In our primary treatment group of 22 patients (median follow-up, 6.4 years), 4 (18%) had local recurrence, 3 (14%) had distant metastasis, and 4 (18%) died of disease. Presence of a nondiploid spindle cell population in 78% of cases of laryngeal SpCC is interpreted as evidence of a neoplastic rather than reactive process. Keratin positivity in nearly two thirds of tumors supports the theory of epithelial origin of these tumors (sarcomatoid carcinoma).

Abstract
Polypoidal squamous cell carcinomas, with a sarcomatous stroma, in the upper aerodigestive tract are very rare but well described tumours. They are associated with a multifarious nomenclature because of different opinions regarding their histology and histogenesis. The main issue is whether the stroma component is a true sarcoma or a benign reactive lesion. In order to draw the attention of otolaryngologists and pathologists to the characteristic features of this rare tumour, two cases originating from the oropharynx are presented. Both tumours were pedunculated and polypoidal, and their bulk consisted of a bizarre sarcoma-like stroma covered with granulation tissue. In some areas of the surface, however, atypical squamous cell epithelium with foci of invasive carcinoma was found. In the vicinity of the latter both tumours contained areas of adenocarcinoma. After surgical excision followed by radiation therapy, there was no recurrence after two and five years, respectively. The histological and immunohistochemical findings support the assumption that these two tumours are carcinosarcomas. Adenocarcinomatous elements in this type of tumour have to our knowledge been reported only twice previously and have never been observed in the pharynx.

Microscopy showed a polypoid atypical spindle cell lesion. Multiple levels failed to reveal an invasive squamous cell carcinoma. On the basis of haematoxylin and eosin stained sections the main differential diagnosis was a pseudosarcoma with an overlying dysplastic squamous mucosa or infiltrating spindle cell carcinoma. Immunohistochemistry showed positive staining for vimentin but no convincing staining with antibodies to cytokeratin and EMA. Ultrastructural analysis also failed to reveal epithelial characteristics. Ploidy analysis by static cytophotometry of the spindle cell proliferation revealed an aneuploid stem line with a DNA index of 1.67. On the basis of this the process was felt unlikely to be reactive and a diagnosis of a spindle cell squamous carcinoma was made. This diagnosis was subsequently supported by a clinical recurrence of the nodule at a six-month follow-up.
