Context.— Amyloidosis is caused by the deposition of misfolded proteins as insoluble eosinophilic material in the extracellular tissues of the body, leading to impairment of organ function. It can be systemic or localized. Localized genitourinary tract amyloidosis is rare and can be incidentally seen; however, in some cases, it can be the only presenting disease. Objective.— To review the clinical presentation and pathologic findings related to primary amyloidosis of the urogenital system and highlight some of the associated pathologic findings based on our personal experience. Data Sources.— Published peer-reviewed literature and personal experience of the senior author. Conclusions.— Primary localized amyloidosis within the urogenital tract can present as a neoplastic process and may be clinically and radiologically considered as a mass. Awareness of primary amyloidosis by pathologists and clinicians is required for accurate diagnosis and proper patient management.

Iron is an assential element for the growth, division, differentiation and functioning of any cell in the body. Iron is virtually important for human and danger at the same time, because with excessive accumulation it causes oxidative stress with formation of highly active oxygen radicals and reactive form of nitrogen that can destroy cell membranes, proteins, nucleic acids, reduce cell viability, with, according to modern concepts, can contribute to the development of many diseases (cardiovascular, rheumatic, gastrointestinal, neurodegenerative, oncological, metabolic and others), and also accelerate the aging process. Part 1 of this review discussed the issues of iron metabolism in human, including its regulation at the cellular and systemic levels, the intake, transport, use, accumulation and export of iron in cells, the role of the labile iron pool in the cytoplasm of cells and plasma non-transferrin bound iron. Data are provided on the causes, frequency and significance of iron overload in the formation of free radicals and the development of oxidative stress. Part 2 of the review provides information on diseases associated with iron overload as well as information on ferroptosis - a new type of iron-dependent regulated cell death. Attention is paid to the works of domestic authors, where it was found that prolonged use of drinking water with a high iron content is unfavorable for the population and leads to an increase in the overall incidence, the development of the diseases of the blood, skin and subcutaneous tissue, musculoskeletal system, digestive system, urogenital system, and allergic diseases. Separate publications are cited on the possibility of a negative effect of iron at concentrations in water of 0.3 mg/l and lower. The material of the review emphasizes the preventive significance of caution attitude to regulating iron in the water in the Russian Federation, where 1/3 of the population uses iron-containing water for drinking, and substantiate the feasibility of establishing a hygienic limit for iron in water not higher than 0.3 mg/l.

Malignant melanoma of the gastrointestinal tract is an uncommon neoplasm that could be primary or metastatic. Small intestine represents the most common site for the metastatic melanoma; however, it could be found anywhere in the gastrointestinal tract. Intussusception is a rare cause of intestinal obstruction in adults compared to children. In 90% of the cases, the underlying cause can be found, and in 65% of the cases, intussusception is caused by the neoplastic process. The majority of the neoplasms are benign, and about 15% are malignant. Metastatic melanoma is one of the most common metastatic malignancies to the gastrointestinal tract; however, the premortem diagnosis is rarely made. Here, we report an uncommon clinical presentation of metastatic melanoma causing intussusception in an 80-year-old man. This diagnosis should be considered in a differential diagnosis in any patient who presents with gastrointestinal symptoms and a history of melanoma.

We report a case of a 35-year-old female who presented to the emergency room (ER) complaining of a pruritic rash involving multiple areas of the body. She had a significant history of cocaine use in the past. She had first developed a similar rash in 2013 when she was diagnosed with cocaine-induced vasculitis. Her urine toxicology had been positive for cocaine in the past until July 2013. She was incarcerated and attended a drug rehabilitation program after which she quit cocaine use, which was consistent with negative urine toxicology on subsequent admissions. Further workup did not reveal any other, autoimmune or infectious, etiology of this clinical presentation. The patient underwent biopsy of the skin lesion that was consistent with thrombotic vasculopathy likely secondary to levamisole.

Tuberculosis affects all tissues of the body, although some more commonly than the others. Pulmonary tuberculosis is the most common type of tuberculosis accounting for approximately 80% of the tuberculosis cases. Tuberculosis of the otorhinolaryngeal region is one of the rarer forms of extrapulmonary tuberculosis but still poses a significant clinical and diagnostic challenge. Over three years, only five out of 121 patients suspected to have tuberculosis of the otorhinolaryngeal region (cervical adenitis excluded) hadMycobacterium tuberculosisculture-proven disease. Additional 7 had histology-proven tuberculosis. Only one patient had concomitant sputum-positive pulmonary tuberculosis. We look at the various clinical and laboratory aspects of tuberculosis of the otorhinolaryngeal region that would help to diagnose this uncommon but important form of extrapulmonary tuberculosis.

Sepsis associated encephalopathy (SAE) is a common but poorly understood neurological complication of sepsis. It is characterized by diffuse brain dysfunction secondary to infection elsewhere in the body without overt CNS infection. The pathophysiology of SAE is complex and multifactorial including a number of intertwined mechanisms such as vascular damage, endothelial activation, breakdown of the blood brain barrier, altered brain signaling, brain inflammation, and apoptosis. Clinical presentation of SAE may range from mild symptoms such as malaise and concentration deficits to deep coma. The evaluation of cognitive dysfunction is made difficult by the absence of any specific investigations or biomarkers and the common use of sedation in critically ill patients. SAE thus remains diagnosis of exclusion which can only be made after ruling out other causes of altered mentation in a febrile, critically ill patient by appropriate investigations. In spite of high mortality rate, management of SAE is limited to treatment of the underlying infection and symptomatic treatment for delirium and seizures. It is important to be aware of this condition because SAE may present in early stages of sepsis, even before the diagnostic criteria for sepsis can be met. This review discusses the diagnostic approach to patients with SAE along with its epidemiology, pathophysiology, clinical presentation, and differential diagnosis.

Sebaceous carcinoma is a rare and aggressive skin tumor. It can be located in any area of the body, the most commonly involved area being the periorbital region. It does not entail a typical clinical presentation, which explains the often late diagnosis. The aim of this report is to outline the rarity of the disease and its atypical clinical description, since to this day, inguinal ulcers with clinical manifestation have not been reported. We present and discuss a case of sebaceous carcinoma with an unusual clinical presentation, in an elderly male patient. The precise approach to genital ulcers, as shown in this case, is a diagnostic challenge that requires a great deal of effort on the part of the clinician.

Introduction. Palatine tonsils are part of the mucosa-associated lymphoid tissue, located in the oropharyngeal region. Although these tissues protect the body from foreign intruders, they are more prone to infections due to their anatomical structure and location. For instance, the differential diagnosis of a white lesion on the palatine tonsil can range from benign to malignant lesions. Oral lymphoepithelial cysts commonly arise as painless, yellowish nodules on the floor of the mouth and the ventral or lateral surface of the tongue. Case Presentation. This paper presents a rare case of an unusual site of a lymphoepithelial cyst (LEC) in the oral cavity. The lesion was located in the tonsil of a 20-year-old woman with a chief complaint of a painless, white lump in the back of the mouth for nine months. Discussion. The differential diagnosis of a white lesion on the palatine tonsil is caused by several factors, such as bacterial, viral, and fungal infections; trauma; stones; cysts; abscess; or cancer. In this case, both the clinical presentation and extra- and intraoral examinations were highly associated with LEC. Oral LEC etiopathogenesis is uncertain, and several theories have been proposed to discuss the causes of LEC. In addition, oral LEC could be monitored without surgical intervention if the nodule is asymptomatic. Conclusion. We emphasize the importance of a thorough clinical examination of oral and oropharyngeal lesions, which are usually neglected.

Fractures of the middle third of the face have increased in number over the past two decades. Trauma to the facial area results in injuries not only to dental structures but also maxillomandibular fractures. In addition, these injuries frequently occur in combination with injuries of other parts of the body. The etiology of these fractures have various causes, such as traffic accidents, falls, assaults, sports, and others. The aim of the study was to assess the knowledge and awareness about LeFort I fracture among undergraduate dental students. A custom made questionnaire comprising of 10 questions to assess the knowledge about LeFort I fracture was formulated and circulated among 100 undergraduate dental students. The responses were then subjected to statistical analysis. Among 100 undergraduate dental students, 52% of them were aware of the types of maxillofacial fractures, and LeFort I fracture is a maxillary fracture, 34% of them have reported that Le Fort I fracture causes disruption of the cribriform plate of the ethmoid bone,35% of them reported that LeFort I fracture might be associated with cerebrospinal fluid leak and 25% of them were still unaware that floating palate is the typical clinical presentation of LeFort I fracture. Also, only 30% were aware that intermaxillary fixation is the management of LeFort I fracture. The present study suggests that among undergraduate dental students, the knowledge about the clinical presentation and the management of LeFort I fracture is inadequate.

Xanthogranulomatous pyelonephritis is a rare and chronic form of pyelonephritis. Patients can present with an array of signs and symptoms including flank pain, fever and weight loss. The insidious nature of its clinical presentation means that it can mimic a neoplastic process. Kidney stone disease, diabetes and female gender are the most common associated factors. Early diagnosis can be difficult, but is vital to avoid sequelae such as abscess formation and involvement of surrounding structures. Management requires a multidisciplinary approach. Definitive resolution can only be achieved through nephrectomy. This article provides an overview and guide to diagnosis, investigation and management.
