Abstract
Basaloid squamous cell carcinoma of the lung is now considered a subtype of squamous cell carcinoma as per the 2015 WHO classification and remains a relatively unknown type of lung cancer due to its rarity. Here we report two cases of basaloid squamous cell carcinoma of the lung and their CT findings to clarify some of the radiologic features of this type of cancer. Two patients aged 85 and 68 years with lung basaloid squamous cell carcinoma visited our institution and underwent surgical resection. On CT, the lesions were 3.1 and 2.8 cm in size, respectively, well-defined, round in shape with lobulated margins and prominent intratumoral necrosis. The latter case was followed after operation for 20 months, and there was no recurrence of the disease on CT. Although very rare, basaloid squamous cell carcinoma should be considered a subtype of lung cancer in tumors sharing these CT findings.

Abstract
A history of an increase in pulmonary mass was presented in the right upper lobe of a 72-year-old male. The bronchial brushing cytology specimens contained many sheet-like or three-dimensional clusters of malignant cells having small to medium-sized, uniform oval to round, and hyperchromatic nuclei, inconspicuous nucleoli, and scanty cytoplasm, admixed with mitotic figures. A coarsely granular chromatin pattern was predominantly noted. We first interpreted it as suspicious of malignancy, such as atypical carcinoid. A right upper lobectomy was performed, and gross examination revealed a centrally cavity-formed tumor lesion, containing asymmetrically thinned wall and looking grayish to whitish, partly adjacent to the bronchiolar wall. On microscopic examination, the tumor was predominantly composed of a solid proliferation of atypical epithelial cells without apparent glandular or squamous differentiation, often arranged in an alveolar growth pattern with peripheral palisading. Immunohistochemically, these atypical cells are negative for all three neuroendocrine markers and thyroid transcription factor 1, whereas positive for 34βE12, p63 and S-100 protein. Therefore, we finally made a diagnosis of basaloid carcinoma with cavity formation. We should be aware that, owing to its characteristic features, cytopathologists might be able to raise basaloid carcinoma of the lung as one of differential diagnoses, based on careful cytological examination.

Abstract
Basaloid squamous cell carcinoma of the lung, an uncommon subtype of non-small cell carcinomas was introduced as a distinct entity in the recently revised World Health Organization (WHO) classification of lung tumours. This rare tumour most commonly develops in males older than 60 years. We report a 23-years-old female patient with basaloid squamous cell carcinoma of the lung who was stage IIB post-operatively. The patient is still alive and healthy 18 months after the operation. This is one of the youngest patient reported with this rare type of tumour.

Abstract
We report a rare case of basaloid squamous cell carcinoma of the lung in a young Japanese woman. An 18-year-old woman presented with productive cough. Chest radiogram and computed tomography (CT) revealed a tumor in the left hilum accompanied by partial atelectasis of the left upper lobe and pleural effusion. Transbronchial fine-needle aspiration cytology supported a tentative diagnosis of primary squamous-cell carcinoma of the lung. The clinical stage was T4N2M1, with multiple bone metastases. Despite a transient response to chemotherapy consisting of carboplatin and paclitaxel, the patient died because of tumor progression 2 months after the start of the chemotherapy. Necropsy established the diagnosis of basaloid squamous-cell carcinoma of the lung. Immunohistochemical studies of the necropsy specimen indicated that the tumor was positive for keratin, vimentin, and S100, and negative for chromogranin A, cytokeratin CAM5.2, and bcl-2. Besides the rarity of the disease itself, the present case seemed to have additional uniqueness in that the patient was 18 years old and female. This is the youngest patient with a case of basaloid squamous cell carcinoma of the lung ever reported.

Abstract
Basaloid carcinoma (BC) of the lung is a rare and an aggressive subtype of non small cell lung cancer. We report a patient with preoperative cytologic features of either lung BC or squamous cell carcinoma. Finally, the tumor was diagnosed as a pure BC of the lung by the immunohistological findings. The patient's recovery was uneventful and remained asymptomatic without recurrence 18 months after surgery. However, considering to the biological behavior of BC, regular follow-up for this patient will be required.

Abstract
The histopathologic type of lung cancer is known to be correlated with tumor behavior and prognosis. However, this classification is subjective and no specific molecular markers have been identified. The aim of this study was to identify protein markers in different types of nonsmall cell lung cancers. Two-dimensional polyacrylamide gel electrophoresis analysis was performed with paired samples of three squamous cell carcinomas, three adenocarcinomas, four large cell carcinomas, and four basaloid carcinomas. We found that 25 proteins in 14 cases of lung cancer were differentially expressed compared to matched nontumorous lung tissues. Among these 25 proteins, 11 proteins were down-regulated and 14 were up-regulated in these four types of lung cancer. Alloalbumin venezia, selenium-binding protein 1, carbonic dehydratase, heat shock 20KD-like protein, and SM22 alpha protein were down-regulated in all 14 cases of lung cancer examined, whereas alpha enolase was consistently up-regulated. Supervised hierarchical cluster analysis based on the 25 differentially expressed proteins showed that basaloid carcinoma formed one independent group, whereas the other three cancer types were not uniquely classifiable. Our findings suggest that basaloid carcinoma is a unique subtype of nonsmall cell lung carcinoma.

Abstract
Abstract
Context.—Primary small cell neuroendocrine carcinoma of the vagina is extremely rare, and its clinical behavior is aggressive. To our knowledge, 22 patients with this tumor have been reported in the English literature to date.
Objective.—To investigate 3 patients with this tumor clinically and pathologically.
Design.—The pathology database at the University of Texas Medical Branch at Galveston was searched, and 3 cases of primary small cell neuroendocrine carcinoma of the vagina were found. The histologic, immunohistochemical, and ultrastructural profiles of the tumors were investigated. The medical charts of the patients were reviewed, and the patients were followed up.
Patients.—Women with the diagnosis of primary small cell neuroendocrine carcinoma of vagina.
Results.—All 3 patients presented with advanced disease, and 2 patients died within 4 months of the initial diagnosis. One 38-year-old patient was newly diagnosed, and her clinical outcome had not yet been determined. The histologic features of all 3 tumors were similar to those of their pulmonary counterpart. All cases were positive for cytokeratin, chromogranin A, and synaptophysin. The expression pattern of thyroid transcription factor 1 was examined in all 3 patients, of whom 2 were negative and 1 was positive with negative clinical and radiologic thyroid or pulmonary findings. Ultrastructural evaluation showed scattered intracytoplasmic electron-dense neurosecretory granules.
Conclusion.—Primary small cell neuroendocrine carcinoma of the vagina has histologic, immunohistochemical, and ultrastructural features similar to those of its pulmonary counterpart. Because thyroid transcription factor 1 can be positive, it should not be used to differentiate primary from metastatic disease. The current therapies have usually resulted in poor outcomes, and new therapeutic modalities should be explored.

Abstract
BACKGROUND Basaloid carcinoma of the lung has been reported as an uncommon and highly aggressive form of nonsmall cell lung cancers. Even in stage I and II of basaloid carcinoma, a 5-year survival rate of only 15% has been reported and it has been suggested that different treatment modalities for basaloid carcinoma should be considered. The aim of this study was to determine the prognostic implications of a basaloid carcinoma of the lung. METHODS This study included a series of 291 surgically resected lung tumors, which were originally diagnosed as a poorly or undifferentiated carcinoma, a small cell carcinoma, or an atypical carcinoid. Of these, 35 basaloid carcinoma patients were identified and compared with 167 poorly differentiated squamous cell carcinoma (PDSC) patients in terms of the preoperative clinical data, the procedure performed, and the survival outcome. RESULTS The overall incidence of basaloid carcinoma was 4.8%. The actuarial 5-year survival rate was 40.6% in patients with PDSC and 36.5% in those with basaloid carcinoma (p = 0.86). In stage I and II patients, the actuarial 5-year survival rate was 53.9% in the PDSC group and 57.2% in the basaloid group (p = 0.97). There were no differences in the recurrence rate and the relapse pattern (p = 0.584). Cox's proportional hazards model revealed that an age equal to 60 years old (hazard ratio 2.179, p = 0.000) and an advanced stage (hazard ratio 2.264, p = 0.000) were the risk factors for postoperative survival in both groups. CONCLUSIONS Basaloid carcinoma of the lung does not have a worse prognosis than the other nonsmall cell lung cancers. Although it is obvious that a basaloid carcinoma is a unique histologic entity, it does not require a different treatment modality due to the similar clinical behavior with other nonsmall cell lung cancers.

Abstract
This article provides a broad overview of tumors that can involve the tracheobronchial tree. For the most part, the clinical, radiographic, and endoscopic presentation of these rare tumors does not differ significantly from the more common tumors of the lung. Appropriate classification of many tracheobronchial tumors ultimately requires complete sampling and a thorough microscopic evaluation. The introduction of ancillary diagnostic techniques such as immunohistochemistry and molecular analysis will continue to refine tumor classification.
