[Non-traumatic arteriovenous malformation of the spleen with fatal hemorrhage]. / Non-traumatická arteriovenózna malformácia sleziny s fatálnym krvácaním.

From the medical point of view, splenic rupture developed either as a result of traumatic injury or as a result of any type of splenic disease represents a very severe and life-threatening condition. We describe the case of a 65-year old man without any obvious traumatic injury who was hospitalised because of left abdominal pain. Investigations performed at admission to the hospital (RTG, USG) failed to indicate any signs of intraabdominal bleeding. However, the patient died suddenly after 24 hours of hospitalisation. At autopsy massive intraabdominal bleeding was found. It was caused by rupture of splenic intraparenchymal hematoma developed as a result of an arteriovenous malformation in the lower pole of the spleen. This case shows the necessity of knowledge of all circumstances of death as well as the necessity of consistent histological investigation of the spleen in such cases.

[Intracardial fungal multiplication of order Mucor in an almost totally carbonised part of a male body found after ten days missing]. / Intrakardiálne pomnozenie plesní rodu Mucor v takmer totálne uhorenom torze tela muza po 10 dnoch od jeho zmiznutia.

Determination of time of death belongs to the most difficult and also the most important issues for the medical examiners, especially those who deal with violent death. Besides the most frequently evaluated postmortal changes it is sometimes possible to perform the evaluation on the basis of less frequently observed findings. One of such findings is for example the fungal multiplication on the body or in the very close vicinity. Knowledge of moulds as well as information about their speed of growth should contribute to confirmation or negation of some information gained during police investigation. In this case report authors describe the macroscopically visible fungal intracardiac multiplication in heart chambers and aorta in an almost totally carbonised body which was missing for only ten days. Based on the molecular examination it was detected that the body belonged to the 64-year-old man who was repeatedly hospitalised in psychiatry for depression with suicidal tendencies. The last hospitalisation was six weeks before death and there was no organic disability. The cause of fire was a naked flame. The cause of death was burn injury or asphyxia. The almost total carbonisation did not allow to perform toxicological investigation. By histological investigation we found the presence of wide long non-septate moulds growing in the heart muscle, which belonged to the order Mucor. Since there was no obvious inflammatory response, we suppose their growth started on the congealed blood after death.

[Unusual lung finding of massive alveolar filling with foamy macrophages in congenital epidermolysis bullosa after amnion fluid aspiration in 15-day-old newborn without any clinical signs of respiratory impairment]. / Neobvyklý plúcny nález masívneho vyplnenia alveolov penovitými makrofágmi pri kongenitálnej epidermolysis bullosa po aspirácii súcastí plodovej vody u novorodenca prezívajúceho 15 dní bez akýchkolvek príznakov poskodenia dýchacích funkcií.

Epidermolysis bullosa represents a group of mechanobullous diseases which are most commonly genetically determined. We describe the case of a 15-day-old female newborn with congenital epidermolysis bullosa which was inflicted on aproximately 1/3 of her skin surface, who died because of incorrigible sepsis with multiorgan failure. The main topic of our report is a description of an unusual pulmonary finding of massive alveolar filling with foamy macrophages after amnion fluid aspiration, which contained a excessive amount of desquamated epidermal cells. Introduced case shows outstanding discrepancy of negative clinical finding on one side and massive histopathological finding on the other.

[Periosteal osteosarcoma - personal experience with five cases]. / Periostální osteosarkom - osobní zkusenost s peti prípady.

The authors present five cases of periosteal osteosarcoma located in the femur (4) and tibia (1) in children and young adults (1 female and 4 males) with an age range of 9 - 23 years (mean age 15 years). Radiographs in all cases showed a broad-based soft tissue mass attached to the cortex with periosteal reaction and in two of them cortical disruption with extensive medullary involvement. Follow-ups were available in four cases (range 11 - 73 months) and revealed pelvic metastasis after 15 months with ultimately rapid dissemination and death in a 9-year-old girl and metastasis to the humerus after 13 months in a 15-year-old boy. The former tumor widely extended into the medullary cavity and an amputation was carried out, the latter had a pure juxtacortical position and an en block resection was performed; both of them were treated with chemotherapy. All the lesions displayed distinctive structural patterns combining a large island of tumorous cartilage and hypocellular, bland-looking myxoid mesenchymal stroma with abrupt transition between both components. Contrary to conventional osteosarcoma, the delicate flocculent osteoid deposits were produced by innocuous stromal cells lacking apparent atypia. They were strictly situated outside the prevailing chondroid areas and disclosed sometimes only after a meticulous search. Immunohistochemical detection of SATB2, S100protein and D2-40 assisted effectively not only in recognition of the real stromal histogenetic derivation, but also in distinction of true differentiation of a heavily mineralized extracellular matrix. Molecular analysis revealed no IDH1/2 mutation in four examined cases. Regardless of unique low-grade morphology in rare periosteal osteosarcoma, an aggressive therapeutical approach similar to conventional osteosarcoma is justified, particularly in the case of a medullary extension.

[Traumatic pseudoaneurysm of descendent thoracic aorta solved by aortal stentgraft repair followed by development of fatal aortoesophageal fistula]. / Traumatická pseudoaneuryzma descendentnej torakálnej aorty riesená aortálnym stentgraftom s následnou fatálnou aortoezofageálnou fistulou.

Traumatic pseudoaneurysms are relatively frequently mentioned in textbooks of pathology and forensic medicine but their incidence in pathological reports is seldom documented. Our described case presented a patient who suffered from chronic alcoholism and who was repeatedly hospitalised because of various injuries including epidural and subdural hematomas. We present a case of a 69-year-old man who was hospitalised after nonspecific blunt chest injury with chest pain and dysphagia. By computed tomography the traumatic pseudoaneurysm of the descendent thoracic aorta was diagnosed pressing the oesophageal wall which was solved by implantation of aortal stent graft (TEVAR - thoracic endovascular aortic/aneurysm repair). Since after the implantation there was no blood leak, no progression of the lesion, he was soon discharged from hospital. The patient was hospitalised again after two months for newly developed haemoptysis. On suspicion of bleeding from aortal arch a carotid-carotid bypass from right to left side was performed and then re-TEVAR was implanted proximally to the first one. The man died two days following the implantation after a massive bleeding from oesophagus due to aortoesophageal fistula. The presented case deals with the etiology of the development of pseudoaneurysms, histomorphological picture of pseudoaneurysm resembling not only an isolated thoracic aortitis but slightly also the Takayashu disease. We suppose that in this case the most probable cause of necrosis and perforation of aortal wall was a decubital necrosis caused by stent graft which led to the fatal aortoesophageal necrosis. Aortoesophageal fistula belongs to the most common lethal complications of the TEVAR.

[Current status of urinary cytology in the evaluation of bladder neoplasms]. / Postavenie a význam cytológie moca v diagnostike uroteliálnych nádorov.

Urine cytology is a reliable method for identification and follow up of the patients who develop high-grade urothelial carcinoma. Reactive changes of superficial and intermediate urothelial cells cytologically often mimic low grade urothelial carcinoma. This is the cause of relatively high number of false positive and false negative results. Diagnostic accuracy can be improved introducing different procedures for material handling namely cytospin and liquid based cytology and new diagnostic protocols such as FISH for chromosomal aberrations or mRNA and miRNA analysis. Most recently Next Generation Sequencing for DNA analysis was applied. Availability of clinical information improves the diagnostic accuracy and shortens the time to diagnosis.

[Undiagnosed Whipple's disease with a lethal outcome]. / Nediagnostikovaná Whippleova choroba s letálnym koncom.

Whipples disease is a rare multisystem disease caused by rod-shaped bacteria Tropheryma whipplei. Although it affects all age groups, the typical patient is a middle-aged white man. The clinical signs are very heterogeneous and depend on the stage of the disease. The most common is abdominal manifestation characterized by weight loss, disability, chronic diarrhea and abdominal pain. Untreated Whipples disease is almost always fatal. We describe probably the first published case of undiagnosed Whipples disease with a lethal outcome in Slovakia, occuring in a 33-year old white man with involvement of the gastrointestinal tract, abdominal lymphatic nodes and brain, who died of bronchopneumonia.
