Abstract Background  Accurate segmentation of head and neck squamous cell cancer (HNSCC) is important for radiotherapy treatment planning. Manual segmentation of these tumors is time-consuming and vulnerable to inconsistencies between experts, especially in the complex head and neck region. The aim of this study is to introduce and evaluate an automatic segmentation pipeline for HNSCC using a multi-view CNN (MV-CNN). Methods The dataset included 220 patients with primary HNSCC and availability of T1-weighted, STIR and optionally contrast-enhanced T1-weighted MR images together with a manual reference segmentation of the primary tumor by an expert. A T1-weighted standard space of the head and neck region was created to register all MRI sequences to. An MV-CNN was trained with these three MRI sequences and evaluated in terms of volumetric and spatial performance in a cross-validation by measuring intra-class correlation (ICC) and dice similarity score (DSC), respectively. Results The average manual segmented primary tumor volume was 11.8±6.70 cm3 with a median [IQR] of 13.9 [3.22-15.9] cm3. The tumor volume measured by MV-CNN was 22.8±21.1 cm3 with a median [IQR] of 16.0 [8.24-31.1] cm3. Compared to the manual segmentations, the MV-CNN scored an average ICC of 0.64±0.06 and a DSC of 0.49±0.19. Improved segmentation performance was observed with increasing primary tumor volume: the smallest tumor volume group (<3 cm3) scored a DSC of 0.26±0.16 and the largest group (>15 cm3) a DSC of 0.63±0.11 (p<0.001). The automated segmentation tended to overestimate compared to the manual reference, both around the actual primary tumor and in false positively classified healthy structures and pathologically enlarged lymph nodes. Conclusion An automatic segmentation pipeline was evaluated for primary HNSCC on MRI. The MV-CNN produced reasonable segmentation results, especially on large tumors, but overestimation decreased overall performance. In further research, the focus should be on decreasing false positives and make it valuable in treatment planning.

Background: Undifferentiated tumours in the head and neck region are not uncommon. They can arise from different sites like in mucosa as well as in salivary glands, soft tissues or lymph nodes. Histopathological examination plays a central role in the diagnosis but difficulties arise with some tumours which are poorlydifferentiated due to their high inter- and intra-observer variability. In those cases, immunohistochemistry has greatly assisted to diagnose the tumours that cannot be accurately identified using routine histopathological procedures. The correct histopathological diagnosis is essential especially in case of malignant tumourwhere subsequent specific therapy is required. The aim of this study was to determine the role of immunohistochemistry for diagnosing undifferentiated malignancy in the head and neck region. Methods: This cross-sectional study was conducted during July 2014 to June 2015. A total of 35 Bangladeshi patient’s specimens of head and neck swelling were collected from two renowned laboratories in Dhaka city.These cases were diagnosed as undifferentiated tumour in histopathological examination.Standard protocol was followed for immunohistochemistry.Then primary immunohistochemical panel which included the markers for Epithelial CK (AE1/AE3),mesenchymal marker (Vimentin) and lymphoid marker (LCA) were used.The cases which were not resolved by primary immunohistochemistry panel, the second panel was applied for further sub classification (Desmin, Chromogranin, CK20, CEA, CD20, CD30, HMB45, NSE). Based on interpretation of immunohistochemical findings final diagnoses were made.Data analysis was performed using the Statistical Package for the Social Sciences for Windows version 22.0 (SPSS, Chicago, Illinois, USA). Results: A total of 35 undifferentiated tumorsof head-neck region were studied.The mean age was 46.3±17.6 years and male to female ratio was 4.8:1. The majority 13 (37.1%) patient had cervical lymphadenopathy, 11 (31.4%) had neck mass and 4(11.4%) had in nasal/sinonasal mass.Regarding histopathologicalcell types, round cell was 21 (60.0%), spindle cell 6 (17.1%), pleomorphic cells 6(17.1%) and epithelioid cells 2(5.7%). In initial histopathological examination, majority 25(71.4%) were undifferentiated malignant neoplasm, 8(22.8%) were metastatic undifferentiated carcinoma, 1(2.9%) was pleomorphic sarcoma and the remaining 1(2.9%) had malignant adnexal tumour. By application of immunohistochemistry, most (33, 94.3%) of the cases were resolved and the two cases remained unresolved. Among the resolved cases majority (15, 45.5%) were lymphoma, 4(12.1%) were metastatic carcinoma, 3(9.1%) were Ewing’s sarcoma and malignant melanoma were found in 3(9.1%) cases. Conclusion: This study supports that the immunohistochemical technique has a fundamental role in the investigation of undifferentiated tumour origin, to determine the correct guidance for treatment and improving the prognosis for head and neck tumour patients.

Introduction: Congenital infantile fibrosarcoma is often misdiagnosed. It may be more common than noted in the literature. We present an unusual case of paediatric head and neck fibrosarcoma. Methods: Restrospective case report and literature review. Results: We report the surgical management of a fibrosarcoma of the tongue in an 8-month-old child where neo-adjuvant chemotherapy was unsuccessful. Conclusion: Surgical resection is the mainstay of treatment, in the head and neck region where critical structures are close to the tumour, complete resection with wide margins can be difficult. The role of chemotherapy is yet to be defined.

Background: Low flow vascular malformations are most common in the head and neck region. Only symptomatic malformations require treatment. Sclerotherapy followed by surgery was considered the gold standard treatment but in the head and neck region, it may produce cosmetic and physiological defects. In the present study, multiple injections of sclerotherapy with 3% sodium tetradecyl sulphate was used for the treatment of low flow vascular malformations.Methods: Twenty cases of low flow vascular malformations of the oral cavity who presented in the outpatient department of ESIC Model Hospital, Ludhiana from 2014-2016 were selected for the study. Only significantly sized (>4 cm) and easily accessible lesions were included. Staged sequential sclerotherapy with 3% STS under strict fluoroscopy control was used as the sole treatment.Results: A total of 20 patients were taken of which, 25% required three sessions, 65% five to six sessions each and 10% required eight sessions each. All patients showed good results with complete regression and no mucosal ulceration.Conclusions: Staged sequential sclerotherapy with 3% STS should be the treatment of choice in low flow vascular lesions involving mucosal and cutaneous structures of head and neck region especially anterior two-thirds of tongue, palate, gingiva, buccal mucosa and lips. Surgical removal may affect critical neurovascular structures and cause cosmetic deformity. So the removal is advisable in life-threatening conditions, lesions requiring general anaesthesia and single sitting removal.

Schwannomas of the head and neck are uncommon tumours that arise from any peripheral, cranial or autonomic nerve. Twenty-five to 45 per cent of extracranial schwannomas occur in the head and neck region and thus are usually in the domain of the otolaryngologist. They usually present insidiously and thus are often diagnosed incorrectly or after lengthy delays, however, better imaging and cytological techniques have lessened this to some degree more recently. For benign lesions conservative surgical excision is the treatment of choice bearing in mind possible vagal or sympathetic chain injury. Malignant schwannomas are best treated with wide excision where possible. The role of adjuvant therapy remains uncertain and irrespective of treatment modality prognosis is poor with an overall survival of 15 per cent. However, recent advances in ras oncogene inhibitors may hold hope for the future.
