Poorly differentiated neuroendocrine carcinoma of the tongue base: a case report / 临床耳鼻咽喉头颈外科杂志

Neuroendocrine carcinoma(NEC) is a malignant tumor derived from neuroendocrine cells, with distinct clinical, morphological and immunohistochemical characteristics. Neuroendocrine carcinoma of the head and neck is very rare in clinic. Larynx is the most common affected site, and the root of the tongue is extremely rare. The clinical manifestations are mainly eating pain, cauliflower like mass in the mouth, and ulcerative lesions that have not healed for a long time. Maxillofacial MRI and contrastenhanced CT are the most commonly used examination tools for such diseases, which can detect the spaceoccupying lesions of tumors. Neuroendocrine granules found in the cytoplasm under pathological light microscope can be diagnosed as neuroendocrine carcinoma. However, for most cases, it is difficult to make a diagnosis only under light microscope, and it is often necessary to make a diagnosis by means of immunohistochemistry and other technical means. This paper reports a case of neuroendocrine carcinoma of the root of the tongue, introduces its characteristics, diagnosis and treatment, and reviews the relevant literature of this case.

A comparative study of anterolateral thigh perforator flap with and without sensory nerve graft for sensation reconstruction in head and neck region / 中华显微外科杂志

Objective To compare the operation effects of sensation restoration after tumor resection in the head and neck defects reconstruction by anterolateral thigh flap with or without sensory nerve transplantation.Methods The application of 76 cases anterolateral thigh flaps in head and neck defects reconstruction after tumor resection from May,2011 to May,2015 were observed.35 patients underwent simultaneous reconstruction with sensory nerve anastomosed perforator based anterolateral thigh flap and 41 patients underwent simultaneous reconstruction without sensory nerve graft based anterolateral thigh flap,which was named as group A and group B,respective ly.The treatment effectiveness of the two groups was compared and graded into First,Second and Third rate.Results All the 76 flaps survived.Satisfying morphology for the maxillofacial region and stage-one healing for the donor site was available.During the 24-week follow-up,group A were 65.71％ (First rate),28.57％ (Second rate),5.72％(Third rate) respectively,and the condition of group B were 31.70％,26.84％,41.46％.The treatment effectiveness of group A was better than that of group B.Postoperative complications were less than group B(P ＜ 0.05).Conclusion Compared with the loss of nerve transplantation of anterolateral thigh perforator flap,sensory nerve anastomosed perforator based anterolateral thigh flap is of great value to reconstruct the defect after resection of tumor in head and neck region and restore the sensation of flap.

Solitary Fibrous Tumor of Head & Neck Region: Problems in Diagnosis Due to “Borderline” Features.

Aims: To report SFT in a 45 years male who had a lobulated tumor in neck for longest duration of 18 years with borderline histomorphology. Presentation of Case: The case discussed is of a forty-five year old Indian man who presented with painless mass in right side of neck for the duration of 18 years with rapid enlargement in last one year. Discussion: Solitary fibrous tumor is an unusual spindle cell neoplasm arising from primitive mesenchymal cell with distinct “patternlesss pattern” on histomorphology. The commonest site for this tumor is pleura but in recent years it has been described in various anatomic sites and is known to involve any region of the body. The extra- pleural sites include extremities, pelvis, head and neck and urogenital region. SFT of Head and Neck region is rare and usually involves deep soft tissues. Morphologically SFT resembles many benign and malignant soft tissue tumors. Conclusion: SFT is a rare tumor in neck region and has to be differentiated meticulously from other common and rare soft tissue tumors. Close follow up is essential after complete surgical excision in cases with “borderline” histomorphology.

Metachronous malignancies in head and neck region: Report of two cases.

The development of a second primary cancer after treatment of the fi rst with radiotherapy or chemotherapy is well documented. Multiple metachronous primary cancers are known to occur in an individual, but it is often seen with hematological malignancies of childhood. The prevalence of multiple primary malignancies (MPM) is between 0.73% and 11.7%. The most frequent malignant associations are ovary-colon, ovary-breast, and breast-breast. The possibility of developing a second metachronous cancer 5 years after undergoing treatment of the initial head and neck cancer is approximately 22%. Here, we report two cases of multiple metachronous malignancies in head and neck region. A 46-year-old woman presented with thyroid and salivary gland neoplasms metachronously and another 21-year-old woman with Hodgkin’ s Lymphoma, mucoepidermoid carcinoma of salivary Gland, and follicular variant of papillary carcinoma of thyroid.

Non-surgical treatment of locoregionally advanced squamous cell carcinoma of the head and neck region / 中国癌症杂志

Deifnitive treatment for locoregionally advanced squamous cell carcinoma of the head and neck region (HNSCC) is challenging, and usually require multidisciplinary efforts involving surgery, radiotherapy, and chemotherapy. Although surgery followed by radiation or chemoradiation therapy remains the standard treatment for resectable disease, combined chemoradiation therapy provides an effective option with organ spearing potential. In addition, combined chemoradiation therapy is the only treatment option for non-metastatic advanced HNSCC. Recently published results from TAX323 and TAX324, two important randomized clinical trials on the efficacy of induction chemotherapy using docetaxel based regimen, showed that induction chemotherapy using TPF can signiifcantly improve patients’ survival as compared to the conventional PF regimen. However, whether TP or TPF induction chemotherapy should be combined with concurrent chemoradiation and considered as part of the standard treatment regimen remains controversial, and requires support from the results of well-designed randomized clinical trial.

Radiotherapy Results of the Non-odgkin's Lymphoma in the Head and Neckt / 대한치료방사선과학회지

This is a retrospecitve analysis of 54 patients with stage I or II Non-odgkin's lymphoma involving the head and neck region treated with curative radiotherapy in the Department of Therapeutic Radiology, Seoul National University Hospital during the period of February 1979 through September 1982. The minimum follow-p period was 24 months. The review of histologic slides was available in 36 cases. Waldeyer's ring was the most common extranodal sites (46%). 41% of patients were in the stage I and 59% in the stage II by Ann Arbor classification. Of the 44 patients who responded after radiotherapy, 24 patients (54.5%) subsequently relapsed. Regional recurrence rate was 29%, distant metastasis was 54% and simultaneous regional recurrence and distant metastasis was 17%. The survival rate and disease free survival at 2 years were 57% and 45% respectively. Those patients with a large primary lesion (over 6cm in diameter), multiple conglomerated. extranodal site and diffuse cell type, experienced a high rate of distant metastasis. Therefore it seems desirable to study the use of adjuvant chemotherapy in those patients with a high probability of distant metastasis.
