Pathological Conditions

Scleroderma-like disorders include a set of entities involving cutis, subcutis and, sometimes, even muscular tissue, caused by several pathogenetic mechanisms responsible for different clinical–pathological pictures. The absence of antinuclear antibodies (ANA), Raynaud’s phenomenon and capillaroscopic anomalies constitutes an important element of differential diagnosis with systemic sclerosis. When scleroderma can be excluded, on the basis of the main body sites, clinical evolution, any associated pathological conditions and specific histological features, it is possible to make a correct diagnosis.

Tumour Differentiation

The diagnosis of cutaneous adnexal neoplasms, a heterogeneous group of entities, is often perceived by practising pathologists as challenging. A systematic approach to diagnosis is necessary for classification of these lesions, which establishes the tumour differentiation (follicular, sebaceous, sweat gland or apocrine) and evaluates histological features differentiating between benign and malignant entities. Consideration of clinical history is a necessary adjunct in evaluation of the adnexal neoplasm, as characteristic anatomical sites are described for many adnexal lesions. In some instances, immunohistochemical studies may also be employed to aid the diagnosis. The differential diagnosis between primary cutaneous adnexal neoplasms and cutaneous metastases from visceral tumours may also be difficult. Clinical, radiological, histological and immunohistochemical characteristics will be further discussed, considering that the correct diagnosis has a significant impact on the patient's management and prognosis.

Pancreatic tissue that has no direct or vascular connection to the main body of the pancreas constitutes ectopic pancreas or heterotopic pancreas (HP). Majority are located in the upper gastrointestinal tract (GIT). HP may be mistaken for neoplasms like neuroendocrine tumour (NET) and adenocarcinoma on endoscopy as well as on histopathology. We report six cases of HP along with review of literature; three of them were misdiagnosed as NET. To the best of our knowledge, this is the first case series of HP from India, rest being case reports. Histopathological features of six cases of HP were analyzed. Variables examined were clinical presentation, age at diagnosis, location, histopathologic type and immunohistochemical profile. Two cases each were seen in duodenum and Meckel’s diverticulum while one case each was seen in stomach and an atretic segment of ileum, a site never reported previously. There were five males and one female with age ranging from one day to 48 years. Patients with gastric and duodenal HP were symptomatic. On histopathology, four cases were intramuscular and two were submucosal. Four cases were of Type I and two cases were of type II. HP should be considered in the differential diagnosis of submucosal upper GI lesions. Awareness, high degree of suspicion and thorough histopathological examination are necessary to arrive at a correct diagnosis. Immunohistochemistry for chromogranin and synaptophysin is useful for confirming the islets especially on small endoscopic biopsies. HP must be considered in the differential diagnosis of submucosal upper GI lesions. Knowledge about this entity, high degree of suspicion and thorough histopathological examination help in arriving at a correct diagnosis and excluding mimics.

Abstract Background COVID-19 pneumonia represents the most severe pandemic of the twenty-first century and has crucial clinical, social and economical implications. The scientific community has focused attention and resources on clinical and radiological features of COVID-19 pneumonia. Few papers analysing the vast spectrum of differential diagnoses have been published. Main body Complexity of differential diagnosis lays in the evidence of similar radiological findings as ground-glass opacities, crazy paving pattern and consolidations in COVID-19 pneumonia and a multitude of other lung diseases. Differential diagnosis is and will be extremely important during and after the pandemic peak, when there are fewer COVID-19 pneumonia cases. The aim of our pictorial essay is to schematically present COVID-19 pneumonia most frequent differential diagnoses to help the radiologist face the current COVID-19 pneumonia challenge. Conclusions Clinical data, laboratory tests and imaging are pillars of a trident, which allows to reach a correct diagnosis in order to grant an excellent allocation of human and economical resources. The radiologist has a pivotal role in the early diagnosis of COVID-19 pneumonia because he may raise suspicion of the pathology and help to avoid COVID-19 virus spread.

There are many areas in medicine in which the diagnosis poses significant difficulties and depends essentially on the clinician’s ability to take and interpret the patient’s history. The differential diagnosis of transient loss of consciousness (TLOC) is one such example, in particular the distinction between epilepsy and ‘psychogenic’ non-epileptic seizures (NES) is often difficult. A correct diagnosis is crucial because it determines the choice of treatment. Diagnosis is typically reliant on patients’ (and witnesses’) descriptions; however, conventional methods of history-taking focusing on the factual content of these descriptions are associated with relatively high rates of diagnostic errors. The use of linguistic methods (particularly conversation analysis) in research settings has demonstrated that these approaches can provide hints likely to be useful in the differentiation of epileptic and non-epileptic seizures. This paper explores to what extent (and under which conditions) the findings of these previous studies could be transposed from a research into a routine clinical setting.

Perivascular epithelioid cell neoplasms represent a group of uncommon mesenchymal tumours with as yet undiscovered benign counterpart. Although perivascular epithelioid cell neoplasms have been described arising in most organ systems as well as in soft tissue and bone, only a small number of perivascular epithelioid cell neoplasms have been reported in the bladder. To date, there is no agreed system for predicting the behaviour of these tumours. We describe a case of a perivascular epithelioid cell neoplasm of the bladder arising in a 57-year-old male and initially diagnosed on biopsy and present a review of the literature focussing on the pathological differential diagnosis and the importance of key histological features in conjunction with a broad immunohistochemical panel. This case report highlights the key features of bladder perivascular epithelioid cell neoplasms that distinguishes these rare neoplasms from other bladder lesions.

Abstract Autoimmune diseases are pathological conditions in which the immune system mistakenly attacks its own tissues. This study evaluates the performance of two techniques, which are identifiers of autoantibody specifics: immunoblot and immunodot. This study was conducted in 300 patients of whom 62 were tested positive for antinuclear antibodies. The patients were initially screened for antinuclear antibodies using indirect immunofluorescence. Then, the identification of specific autoantibodies such as anti-extractable nuclear antigens (ENAs) was carried out using the immunoblot and immunodot techniques. The results showed that immunoblot and immunodot did not present a significant difference in their sensitivity against anti-SSA/52, SSB, CENP-B, PCNA, U1-snRNP, Jo-1, Pm-scl, and Mi-2 (p > 0.05). However, the two techniques showed a significant difference in their sensitivity toward autoantibodies anti-DNAn, anti-histone, anti-SmD1, and anti-ds-DNA (p < 0.05). The immunoblot data were in complete accordance with the immunodot data (100%) regarding the detection of autoantibodies such as anti SSA/52, SSB, CENP-B, PCNA, U1-snRP, Jo-1, Pm-scl, and Mi-2, 80% regarding SmD1, and 75% concerning ds-DNA. We should certainly pay closer attention to the efficiency of the techniques used in the diagnosis of autoimmune diseases.

Lymphangioma Circumscriptum

Genital warts are common relative to other verrucous lesions of the anogenital region. Consideration of the differential diagnosis of verrucous anogenital lesions is necessary, however, to make a correct diagnosis consistently and to avoid futile, painful, and possibly traumatic attempts at treatment. In this report, I describe a child with a history suspicious for sexual abuse who was treated with inappropriate measures because of misdiagnosis of perianal lymphangioma circumscriptum as genital warts. The pathogenesis, differential diagnosis, and treatment of lymphangioma is presented. CASE REPORT A 5-year-old Hispanic boy was referred by his pediatrician to the Dermatology Service with an eruption of red papules on the left buttock and perianal region.

Clinical Patterns

Seven cases of brain tumors occurring in infants are presented. Six occurred in males and one was in a female. Three of them arose in the cerebellum while the other four were supratentorial. The tumors included two medulloblastomas, one [See Table II in Source Pdf] spongioblastoma polare, one ependymoma, one astrocytoma and one hemangioblastoma. The seventh case probably was also one of medulloblastoma. One of the proven medulloblastomas was supratentorial, which is unusual so faras location is concerned. The hemangioblastoma arose in the cerebrum. The location of this tumor is also a rare one and to my knowledge, it is the first case of its type reported in an infant in whom full recovery occurred following removal of the tumor. The diagnosis was unsuspected in four cases. Three of these infants were believed to be suffering from congenital hydrocephalus while the fourth was thought to be afflicted with encephalitis. The ways in which the correct diagnosis might have been made are discussed. Since bizarre clinical patterns are sometimes produced by brain tumors in infants and the diagnosis frequently overlooked, the possibility should be kept in mind by the pediatrician in considering the differential diagnosis of conditions producing signs referable to the nervous system.

Cystic Fibrosis—NCFRF. 16 mm., color, sound, showing time 32 minutes. Produced in 1961 by Samuel L. Schulman for the National Cystic Fibrosis Research Foundation, medical supervision by Giulio J. Barbero, M.D. Philadelphia. Procurable on purchase from National Cystic Fibrosis Research Foundation, 521 Fifth Avenue, New York City 17. Procurable on loan from American Medical Association, Motion Picture Library, 535 N. Dearborn Street, Chicago 10. This film has been prepared to aid physicians in making a correct diagnosis and to instruct them in the techniques currently being used to prolong life in cases of cystic fibrosis. Following the introductoy remarks there is a good discussion of the presenting symptoms, the differential diagnosis, the multiple system involvement, hereditary aspects, therapy, and prognosis. The film brings out well the panexocrine involvement, the clinical variability, and the fact that the disease is not an all or none phenomenon but rather a disease of all grades of severity and is a disease in which no single test is applicable to the exclusion of others. The diagrams and patient demonstrations are good. Perhaps too much review of older methods of therapy and diagnosis is given, but this serves as a background for the newer recommended procedures. More emphasis could have been given to the tremendous burden, both financial and emotional, this disease is on parents. This is an excellent instructive film and it emphasizes the many problems of cystic fibrosis as related to the diagnostic tools available and to forms of therapy. The photography and sound are satisfactory. It is recommended for pediatricians, general practitioners, house staff, and medical students.

Заболеваемость раком яичников в России в последнее время остается на высоком уровне. В мире более ста тысяч женщин умирают вследствие протекания данного заболевания. За последнее десятилетие заболеваемость острым эндометритом также неуклонно возрастает. Острый эндометрит обладает полиморфизмом симптомов, лабораторных и ультразвуковых изменений и вследствие этого тяжело поддается диагностике и дифференциальной диагностике. В условиях стационара обследованы 100 пациенток с раком яичников II-III стадии и 90 пациенток с диагнозом острого эндометрита. Им выполнялось ультразвуковое исследование. Полученные результаты подвергались обработке и математико-статистическому анализу, включающему расчёт показателей дезинтеграции, сетевое моделирование, математическое ранжирование. Изучение ультразвуковых изменений кровотока в маточных и яичниковых сосудах и венах у 100 заболевших раком яичников и 90 заболевших острым эндометритом дал возможность выделить ведущие дифференциально-диагностические аспекты. Характеристики дезинтеграции, в одном ряду со средними значениями локального кровотока, объективизируют дифференциацию рака яичников и острого эндометрита. В согласовании с дифференциально-диагностической значимостью ультразвуковых характеристик артериального кровотока в маточных и яичниковых сосудах построена сетевая модель дифференциальной диагностики рака яичников и острого эндометрита по более приоритетным переменам, собственно, что разрешает уменьшить размер и время обследования пациента и постановки верного диагноза The incidence of ovarian cancer in Russia has recently remained at a high level. In the world, more than a hundred thousand women die as a result of the course of this disease. The incidence of acute endometritis has also been steadily increasing over the past decade. Acute endometritis has a polymorphism of symptoms, laboratory and ultrasound changes and, as a result, is difficult to diagnose and differential diagnosis. 100 patients with stage II-III ovarian cancer and 90 patients with acute endometritis were examined in the hospital. They performed an ultrasound examination. The obtained results were processed and subjected to mathematical and statistical analysis, including the calculation of disintegration indicators, network modeling, and mathematical ranking. The study of ultrasound changes in blood flow in the uterine and ovarian vessels and veins in 100 patients with ovarian cancer and 90 patients with acute endometritis made it possible to identify the leading differential diagnostic aspects. The characteristics of disintegration, along with the average values of local blood flow, objectify the differentiation of ovarian cancer and acute endometritis. In accordance with the differential diagnostic significance of the ultrasound characteristics of arterial blood flow in the uterine and ovarian vessels, a network model for the differential diagnosis of ovarian cancer and acute endometritis is constructed according to higher priority changes, which actually allows reducing the size and time of the patient's examination and making the correct diagnosis
