Primary glandular tumors of the urachus and urinary bladder are an intriguing group of clinically and morphologically diverse neoplasms for which there have been recent refinements in diagnostic subclassification and advances in molecular pathology. In addition, the urachus and urinary bladder may be secondarily involved by tumors with glandular differentiation that demonstrate remarkable morphologic, immunophenotypic, and molecular overlap. Thus, surgical pathologists need to be aware of the broad differential diagnosis of glandular tumors that involve the urachus and urinary bladder and have a practical diagnostic framework to evaluate these lesions in routine clinical practice. In this review, we summarize the salient clinical, morphologic, immunohistochemical, and molecular features of glandular tumors of the urachus and urinary bladder, including mucinous cystic tumors of the urachus, noncystic urachal adenocarcinomas, urothelial carcinomas with glandular or pseudoglandular features, primary urinary bladder adenocarcinomas, and Müllerian-type carcinomas, highlighting the strengths and limitations of various diagnostic features and ancillary tests, as well as the need for close clinical and radiographic correlation.

Sarcoidosis is a chameleon disease of unknown etiology, characterized by the growth of non-necrotizing and non-caseating granulomas and manifesting with clinical pictures that vary on the basis of the organs that are mainly affected. Lungs and intrathoracic lymph nodes are the sites that are most often involved, but virtually no organ is spared from this disease. Histopathology is distinctive but not pathognomonic, since the findings can be found also in other granulomatous disorders. The knowledge of these findings is important because it could be helpful to differentiate sarcoidosis from the other granulomatous-related diseases. This review aims at illustrating the main clinical and histopathological findings that could help clinicians in their routine clinical practice.

Abstract Inflammatory pseudotumors of the spleen are extremely rare in children. To our knowledge, only 3 cases of splenic inflammatory pseudotumors have been reported. An inflammatory pseudotumor of the spleen was found incidentally during the workup of vesicoureteral reflux disease in a 6-year-old girl. The clinical, pathologic, immunophenotypic, and molecular features and the differential diagnostic features are discussed here. Splenic inflammatory pseudotumors, although rare, should be considered in the differential diagnosis of a mass lesion of the spleen in children.

We illustrate a case of an inflammatory myofibroblastic tumor (IMT) involving the bladder in a woman with dysuria and review the literature and differential diagnosis. Inflammatory myofibroblastic tumor, also referred to as pseudosarcomatous myofibroblastic proliferation, is a rare lesion that can arise in the genitourinary system and is characterized by a fascicular arrangement of myofibroblasts with admixed inflammatory cells and slitlike vessels. Urinary bladder IMT can be a diagnostic pitfall because its histologic features (brisk mitoses, invasion into muscularis propria, and prominent nucleoli) can mimic malignancy. The differential diagnosis of urinary bladder IMT includes sarcomatoid carcinoma and leiomyosarcoma. Diagnostic features such as bland nuclear chromatin, ganglion-like cells, pale eosinophilic cytoplasm with long processes, overexpression of anaplastic lymphoma kinase (immunohistochemistry or gene rearrangement studies), and the absence of atypical mitoses help distinguish IMT from its malignant mimics. Current controversies regarding postoperative spindle cell nodule and IMT are discussed.

Introduction. Capnography is an essential part and standard monitoring tool during the perioperative period, which can be invaluable in detecting anaesthetic equipment malfunction. Case report. The atypical, ??tails-up?? capnographic waveform was noticed during routine surgical operation. Comprehensive physico-mathematical and graphical explanation of this complex capnographic pattern has been given, together with in-depth analysis of possible differential diagnosis and clinical significance for routine clinical practice. Conclusion. ?Tails-up?? capnographic trace gives early clue to diagnosing and fixing the problem of cracks in sampling line, before leading to an inadequate course of action. The understanding of the physics and physiology behind capnography is of vital importance for the analysis of capnographic waveforms, for early detection of anaesthetic equipment malfunction and for safe clinical practice.

Differential diagnosis of ventricular and supraventricular wide QRS complexes arrhythmias remains one of the most urgent and serious problems of modern cardiology. High-precision intracardiac and transesophageal electrophysiological examination cannot be widely used in routine clinical practice because of the complexity of using, the risk of complications, and the necessary of special equipment. The availability and simplicity of electrocardiogram registration was the reason for study and development of ECG criteria and algorithms for differential diagnosis. However, their low accuracy, variety, complexity and laboriousness of application often leads to diagnostic errors and low usage of clinicians.

In recent years, outstanding progress has been made in the diagnosis and treatment of cardiomyopathies. Genetics is emerging as a primary point in the diagnosis and management of these diseases. However, molecular genetic analyses are not yet included in routine clinical practice, mainly because of their elevated costs and execution time. A patient-based and patient-oriented clinical approach, coupled with new imaging techniques such as cardiac magnetic resonance, can be of great help in selecting patients for molecular genetic analysis and is crucial for a better characterisation of these diseases. This article will specifically address clinical, magnetic resonance and genetic aspects of the diagnosis and management of cardiomyopathies.
