Carcinoid Tumor of the Middle Ear Containing Serotonin and Multiple Peptide Hormones A Case Report and Review of the Pathology Literature

A 69-year old man complaining of longstanding hearing loss and mild otorrhea was found to have a mass obliterating the external auditory canal and polypous tympanic mucosa with accompanying absence of the tympanic membrane and ossicular chain. Tumors excised from the external auditory canal and tympanum showed histologic features essentially characteristic of a carcinoid tumor: a ribbon or festoon arrangement of tumor cells, formation of anastomosing cords and glandular spaces, presence of numerous argyrophilic as well as argentaffin secretory granules within many of the tumor cells, and ultrastructur-al evidence of neurosecretory granules in the tumor cell cytoplasm. Immunohistochemically, the tumor was found to contain not only neuronal marker substances such as neuron-specific enolase, S 100 protein and chromogranin A, but also serotonin and multiple peptide hormones such as pancreatic polypeptide, glucagon, cholecystokinin and leucine-enkephalin. A review of the pathology of 17 previous cases of carcinoid of the middle ear suggested that this type of carcinoid may have a variegated hormone profile among carcinoids of foregut origin, and hormonally may resemble ileal carcinoid arising from the midgut, although their histogenetic origins may differ, because of frequent production of serotonin.

CARCINOID TUMOR OF THE MIDDLE EAR: An Immunohistochemical and Electron Microscopic Study Report of a Case

A primary tumor of the middle ear was examined histologically, histochemi-cally, immunohistochemically and ultrastructurally. Neuroendocrine cell differentiation, a carcinoid feature, was demonstrated by the presence of numerous argyrophil granules, as well as positive serotonin, glicentin, glucagon, and human pancreatic polypeptide (hPP) granules in some of the Grimelium-positive cells. Chromogranin A was also detected in the cells, but much less frequently than Grimelius-positive staining. Neither neuron-specific enolase (NSE) nor epithelial membrane antigen (EMA) was demonstrated in the tumor. Mucin was demonstrated only intraluminally. Electron microscopy revealed many typical neurosecretory granules in tumor cells, but no apical mucin granules. The tumor appeared to be benign, and there has been no sign of recurrence during a postoperative period of one year. ACTA PATHOL JPN38: 1453–1460, 1988.     

分泌性中耳炎中耳积液和血清中sIL－2R水平的初步研究

应用酶联免疫吸附法（ＥＬＩＳＡ）对３０例正常人血清（对照组）和６０例分泌性中耳炎患者（ＳＯＭ组）中耳积液和血清中可溶性白细胞介素２受体（ｓＩＬ－２Ｒ）进行了检测。结果示ＳＯＭ组血清ｓＩＬ－２Ｒ水平明显高于对照组，ＭＥＦ中其含量明显高于血清；鼻咽癌组血清及ＭＥＦ中ｓＩＬ－２Ｒ水平明显高于─般ＳＯＭ组；粘液组高浆液组；慢性组高于急性组（均Ｐ＜０．０１）。提示：血清及ＭＥＦ中ｓＩＬ－２Ｒ水平的测定有助于对ＳＯＭ患者免疫状态的评估；ＭＥＦ中ｓＩＬ－２Ｒ可能主要由局部中耳粘膜产生；ＭＥＰ中高浓度的ｓＩＬ－２Ｒ存在可能是ＳＯＭ迁延不愈的─个原因。     

大脑中动脉血流变化对估计脐带绕颈胎儿预后的价值

目的探讨大脑中动脉血流变化对估计脐带绕颈胎儿预后的价值。方法选取2006年1月~2006年9月足月妊娠妇女51例。其中观察组39例,均为脐带绕颈一周并经阴道分娩。结合胎儿预后将观察组分为胎窘组(15例)和正常组(24例)。对照组12例,为随机选择的同期正常妊娠并顺产的妇女。应用彩色多普勒超声技术对全部孕妇于临产前和活跃早期检测胎儿大脑中动脉阻力指标-收缩期峰值流速/舒张末期流速(S/D)、阻力指数(RI)和搏动指数(PI)。结果(1)临产前,胎窘组胎儿大脑中动脉血流S/D、RI、PI值较对照组和正常组皆显著升高(P<0.05);而对照组和正常组比较,差异不显著(P>0.05)。(2)活跃早期胎窘组胎儿大脑中动脉血流S/D、RI、PI值较对照组和正常组皆显著降低(P<0.05);而对照组和正常组比较,差异不显著(P>0.05)。结论大脑中动脉血流阻力指标的变化与脐带绕颈胎儿不良预后密切相关;临产前监测脐绕颈胎儿MCA血流阻力指标的变化可以作为早期评估胎儿预后的理想方法。

Stimulation of cranial vessels excites nociceptive neurones in several thalamic nuclei of the cat

Summary Extracellular recordings were made in the thalamus of cats anaesthetized with chloralose and urethane following electrical, mechanical and chemical stimulation of the superior sagittal sinus or middle meningeal artery. Facial receptive fields were looked for using electrical and mechanical stimuli. The locations of fifty-six cells were verified histologically. Twenty six cells were located in the ventroposteromedial nucleus (VPM) and six in its ventral periphery (VPMvp). All units in VPM had facial receptive fields, usually involving the first trigeminal division. Cells with nociceptive receptive fields or responding to the craniovascular application of bradykinin were often found in the periphery or “shell” region of VPM. Other craniovascular nociceptive cells were found in VPMvp, in the posterior group and in the intralaminar complex. This study shows that craniovascular afferents in the cat project to several thalamic nuclei and implicate VPM especially in craniovascular nociception.
