Adenomyoepithelioma is an uncommon benign tumor of the breast. We present the fine needle aspiration cytologic features of adenomyoepithelioma in a 23 year-old Korean women, initially diagnosed as fibroadenoma. Aspiration cytologic findings of the left breast mass revealed high cellularity, small to medium sized, less cohesive epithelial clusters, rich naked cells and amorphous materials on background. The epithelial cells were round and uniform with no cytologic atypia or mitosis. Myoeplthelial cells were conspicuous with peripheral rimming along the epithelial clusters. Small amount of fibrotic stromal tissues were observed. Distinguishing features from typical fibroadenoma are less tight epithelial clusters, dyscohesive epithelial cell aggregates, more abundant naked cells and scant stromal tissue fragments.

Subcutaneous fat necrosis in neonates is a rare disease characterized by skin lesions, which may be single or multiple, poorly circumscribed and often tender erythematous nodules or plaques on cheeks, buttocks, back, arms, and thighs. These symptoms are usually self-limited; resolution occurs over a period of weeks to months. Subcutaneous fat necrosis affects full term and healthy-appearing infants who have experienced perinatal distress such as hypoxic insult, birth trauma and hypothermia. Most skin lesions appear within the first two weeks of life. We experienced a case of subcutaneous fat necrosis in a neonate with hypoxic insult and report the case with a brief review of the literature.

Fine needle aspiration cytologic features of a case of insular carcinoma of the thyroid in a 23-year-old woman who presented a palpable neck mass is described. The aspirate showed cellular smear arranged in trabeculae, solid or loose clusters, and microfillicles in necrotic background. The tumor cells had uniform, small round, hyperchromatic nuclei. The chromatin was finely granular, and nuclear membrane was smooth. Nucleoli were not discernible. Nuclear pleomorphism was minimal. The cytoplasm was usually scanty, pale, poorly outlined, and almostly amphophilic. Sometimes paranuclear cytoplasmic vacuoles were noted. final diagnosis was confirmed by total thyroidectomy as insular carcinoma.

Foreign body aspiration (FBA) is a common accident in young children. Undiagnosed and retained foreign bodies may result in severe early and late complications such as asphyxia, pneumonia, atelectasis and bronchiectasis. Moreover, because it can mimic bronchiolitis, croup or asthma, an accurate history and a high index of suspicion are of paramount importance for early diagnosis. With our experience on bronchial FBA initially misdiagnosed as acute bronchiolitis, we emphasize that a minute radiological finding should not be neglected and a repeat chest radiograph may be helpful when the initial study shows normal findings. Multidetector computed tomography is a very useful noninvasive diagnostic modality for FBA.

This paper presents a neural network-based near-optimal routing algorithm. It employs a modified Hopfield Neural Network (MHNN) as a means to solve the shortest path problem. It uses every piece of information that is available at the peripheral neurons in addition to the highly correlated information that is available at the local neuron. Consequently, every neuron converges speedily and optimally to a stable state. The convergence is faster than what is usually found in algorithms that employ conventional Hopfield neural networks. Computer simulations support the indicated claims. The results are relatively independent of network topology for almost all source-destination pairs, which nay be useful for implementing the routing algorithms appropriate to multi -hop packet radio networks with time-varying network topology.
