Giant pedunculated hepatocellular carcinoma with hemangioma mimicking intestinal obstruction

<p>Abstract</p> <p>Background</p> <p>Pedunculated hepatocellular carcinoma (P-HCC) has rarely been reported and is characteristically large and encapsulated. Only sporadic cases have been published, in which P-HCC was combined with other liver tumors (mostly benign), making the diagnosis difficult.</p> <p>Case presentation</p> <p>We report a patient who was admitted to our hospital with clinical features of intestinal obstruction and a palpable mass in the right iliac fossa. Ultrasound, computed tomography and magnetic resonance imaging demonstrated an encapsulated mass of unclear origin and characteristics of liver hemangioma. Laboratory tests revealed elevated α-fetoprotein (> 800 ng/ml) and cancer antigen 125 (> 51.2 U/ml). With a possible diagnosis of giant liver hemangioma, we proceeded to surgery. During surgery, a giant pedunculated tumor was discovered on the inferior surface of the right lobe of the liver, hanging free in the right abdominal cavity towards the right iliac fossa. The macroscopic appearance of the tumor was compatible with liver hemangioma. Tumor resection was performed at a safe distance, including the pedicle. The rest of the liver appeared normal. Histopathological examination revealed grade II and III HCC (according to Edmondson-Steiner's classification) with nodular configuration, central necrosis, and infiltration of the capsule. Underneath the tumor capsule, residual tissue of a cavernous hemangioma was recognized. The resection margins were free of neoplastic tissue.</p> <p>Conclusion</p> <p>This rare presentation of a giant P-HCC combined with a hemangioma with features of intestinal obstruction confirmed the diagnostic difficulties of similar cases, and required prompt surgical treatment. Therefore, patients benefit from surgical resection because both the capsule and the pedicle prevent vascular invasion, therefore improving prognosis.</p

Σπλαχνική λεϊσμανίαση στον σκύλο και παράγοντες κινδύνου

ΕΙΣΑΓΩΓΗ: Η σπλαχνική λεϊσμανίαση είναι ένα λοιμώδες νόσημα που προκαλείται από το πρωτόζωο Leishmania και μεταδίδεται με την βοήθεια της σκνίπας Phlebotomus spp. Τα παράσιτα της Leishmania μπορούν να προσβάλουν τόσο τους σκύλους όσο και τους ανθρώπους και η πάθηση που προκαλείται λέγεται σπλαχνική λεϊσμανίαση. Το νόσημα είναι εξαιρετικά κοινό στις τροπικές και υποτροπικές περιοχές του κόσμου. ΣΚΟΠΟΣ: Σκοπός της παρούσας έρευνας ήταν η διερεύνηση πιθανής ύπαρξης συσχέτισης μεταξύ του μήκους τριχώματος , της ηλικίας ,του φύλου, της χρήσης ή όχι κολάρου δελταμεθρίνης και του τόπου διαβίωσής του σκύλου με την μόλυνση από την Leishmania Infantum. ΜΕΘΟΔΟΙ: Η παρούσα έρευνα είναι μία αναδρομική μελέτη ασθενών – μαρτύρων. Συγκεντρώθηκαν δεδομένα για εκατό σκύλους από το κτηνιατρικό εργαστήριο PROVET LABORATORIES και αναλύθηκαν με την χρήση του στατιστικού πακέτου SPSS Ver.25 .Η στατιστική ανάλυση πραγματοποιήθηκε με μοντέλα λογιστικής παλινδρόμησης. ΑΠΟΤΕΛΕΣΜΑΤΑ: Όσον αφορά το μήκος τριχώματος βρέθηκε ότι το κοντό τρίχωμα αποτελεί προγνωστικό παράγοντα της σπλαχνικής λεϊσμανίασης (OR=1.310, 95% CI [1.214, 2 .079], p-value=0,004). Ακόμη, διαπιστώθηκε ότι υπάρχει συσχέτιση μεταξύ του τόπου διαβίωσης σε εξωτερικό χώρο και της λοίμωξης από Leishmania Infantum (OR = 1.173, 95% Cl [1.153, 1.919], p-value=0.032). . Όσον αφορά το φύλο, τη χρήση κολάρου δελταμεθρίνης και την ηλικία δεν βρέθηκαν να σχετίζονται με την σπλαχνική λεϊσμανίαση. ΣΥΜΠΕΡΑΣΜΑΤΑ: Η γνώση των παραγόντων κινδύνου για τη μόλυνση του σκύλου με το πρωτόζωο της σπλαχνικής λεϊσμανίασης οδηγεί στην αποτελεσματικότερη πρόληψη και στον περιορισμό των οροθετικών σκύλων που αποτελούν πηγή μόλυνσης για τις σκνίπες, προς όφελος της δημόσιας υγείας.INTRODUCTION: Visceral leishmaniasis is an infectious disease caused by the protozoan Leishmania and is transmitted by the mosquito Phlebotomus spp. Leishmania parasites can infect both dogs and humans and this condition is called visceral leishmaniasis. The disease is extremely common in tropical and subtropical regions of the world. PURPOSE: The purpose of the study was to investigate the existence of association among the hair length, age, gender, use or not use of deltamethrin collar and place of residence of the dog with theinfection with Leishmania Infantum. METHODS: This study is a retrospective one. The data werecollected for one hundred dogs from the veterinary laboratory PROVET LABORATORIES and were analyzed by using SPSS ver.25 program. Statistical analysis was performed with logistic regression models. RESULTS: It was found that short hair length is a predictor of viscelar leismaniasis (OR=1.310, 95% CI [1.214, 2.079], p-value=0,004) . Furthermore, it was found that there is an association between the place of residence (outdoor location) and the Leishmania Infantum infection (OR = 1.173, 95% Cl [1.153, 1.919], p-value=0.032). No statistically significant associations were found for gender, age and use of a deltamethrin collar with visceral leishmaniasis. CONCLUSIONS: The knowledge of risk factors for the infection of the dog with the protozoan of visceral leishmaniasis leads to more effective prevention and lower number of positive dogs that are a source of infection for mosquitoes,and benefits public health

De Garengeot's hernia in a 60-year-old woman: a case report

<p>Abstract</p> <p>Introduction</p> <p>De Garengeot first described the presence of the appendix within a femoral hernia in 1731.</p> <p>Case presentation</p> <p>We report the case of a 66-year-old Caucasian woman who presented with acute appendicitis within an incarcerated femoral hernia. This is the first reported case of de Garengeot's hernia in the Balkan area.</p> <p>Conclusions</p> <p>Appropriate management without incurring any delay for radiological imaging can be promising for an uneventful postoperative course. The treatment of choice of this disease entity is emergency surgery and consists in simultaneous appendectomy through the hernia incision and primary hernia repair. In patients with large hernia defects or in older people the use of mesh for repairing the hernia defect can be an excellent choice.</p
