Abstract

An adenomyoepithelioma of the breast is a rare tumor characterized by biphasic proliferation of both epithelial and myoepithelial cells. This tumor is generally considered as a benign neoplasm, and there are few reports describing the imaging features of this tumor through 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET). Here, we report a case of an adenomyoepithelioma that showed strong uptake of FDG on PET similar to that observed with a malignant tumor. A 73-year-old woman presented to our hospital with a 3.5-cm, mobile, and elastic hard tumor in the upper area of the left breast. Although the findings of mammography, ultrasonography, and contrast-enhanced magnetic resonance imaging suggested that the tumor was malignant, it was diagnosed as an adenomyoepithelioma by core needle biopsy. An invasive ductal carcinoma, 0.5-cm in size, was detected in the medial upper area of the ipsilateral breast during an examination. Although FDG-PET demonstrated no lymph node or distant metastases from the invasive ductal carcinoma, strong uptake of FDG was detected in the adenomyoepithelioma. Breast conserving surgery and sentinel lymph node biopsy for the invasive ductal carcinoma together with resection of the adenomyoepithelioma was performed. A diagnosis of adenomyoepithelioma was confirmed through histologic examination of the resected specimen. This case indicates that some adenomyoepitheliomas may show a strong uptake of FDG on PET, which resembles a malignant tumor., (© 2016 Wiley Periodicals, Inc.)

Abstract

The present study has investigated the role of ATP in the induction of synaptic plasticity, using local application of ATP by picopump administration into the stratum radiatum of guinea pig hippocampal region CA1. Excitatory postsynaptic currents (EPSCs) evoked by stimulation of Schaffer collateral/commissural afferents synapsing on CA1 pyramidal cells of hippocampal slices were monitored in voltage-clamp mode, using whole-cell recording. Brief local application of ATP (1 mM) induced an inward current, usually consisting of early- and late-phase components. Because the late-phase component of an ATP-induced current was largely inhibited by Ca2+-free solution, this component is supposed to depend on extracellular Ca2+. After local application of ATP, long-term synaptic modification of EPSCs was induced: LTP was detected in neurons exhibiting a small late Ca2+ current, while LTD was obtained from recordings showing a large late Ca2+ current in response to ATP application. There was a statistically significant correlation between the magnitude of long-term plastic changes and the size of Ca2+ currents in response to ATP application. Furthermore, there was significant difference between the average size of the Ca2+ current in the LTP group and the size in the LTD group. These results suggest that a small Ca2+ influx in response to ATP application induces LTP, whereas a large one induces LTD in guinea pig hippocampal CA1 neurons.
