The polymorphism of codon 72 in the p53 tumour suppressor gene has been associated in the last decade with the risk of developing various neoplasias. An influence of this polymorphism on ovarian and endometrial cancer has also been suggested. We examined the genotype frequency of this polymorphism in archival samples from 56 patients with endometrial neoplasias and 51 patients with ovarian neoplasias. Cervical smears from 30 healthy, human papillomavirus (HPV)-negative women with normal cytology and colposcopy, served as control sample. Women with ovarian neoplasias, especially adenocarcinomas, had Arg/Arg more often than healthy controls [odds ratio (OR) 4.16 at P = 0.0058]. No statistically significant difference was found between women with endometrial cancer and controls. Differentiation of ovarian tumours did not appear to be associated in a statistically significant manner with the genotype, whereas a positive linear trend of Arg/Arg towards poor differentiation was noted in endometrial malignancies (mainly endometrioid adenocarcinomas). Our results suggest that homozygous arginine at codon 72 of p53 may represent a risk factor for developing ovarian malignancies and may affect the differentiation of endometrial cancer. Further studies need to be carried out in order to establish the clinical use of this polymorphism for risk assessment and possibly outcome prediction of ovarian and endometrial neoplasias.

Sweet syndrome (SS) is a rare inflammatory process presenting with painful erythematous skin eruptions, accompanied by fever and neutrophilia. It is associated with upper respiratory infection in fertile women (classic form), malignancy, infections, drugs and autoimmune diseases. Its pathogenesis remains to be determined. Nevertheless, cytokines may have a prominent role, due to a rapid response after corticosteroid administration. We describe a 32-year-old female with autoimmune hepatitis on azathioprine and prednisone, presenting with fever and inflammatory skin eruptions. Histologic examination of the skin lesions showed neutrophilic infiltrations of the dermis, confirming the diagnosis of SS. Concurrently, she tested borderline positive for recent CMV infection.

Coronavirus disease 2019 (COVID-19) is a viral respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The respiratory system is the main target of the virus; however, apart from lung disease, a relatively large proportion of patients develop thrombosis as well. We present the case of a 19-year-old male who was admitted after contracting community-acquired right-sided pneumonia. The patient had a history of COVID-19 infection four weeks before admission. The echocardiographic assessment revealed a 16 x 6-mm right ventricular (RV) thrombus. He underwent a cardiovascular magnetic resonance (CMR) study, which confirmed the findings. After ruling out the most common causes of hypercoagulability, COVID-19 was judged to be the cause of the thrombus. The patient was treated with warfarin. Follow-up imaging with echocardiography and CMR six months later revealed complete resolution of the thrombus. Hypercoagulability is a major complication of COVID-19 and in situ thrombosis can occur both in the arterial and venous circulation. The recognition of intracardiac thrombi even in low-risk patients with a history of COVID-19 infection and the immediate initiation of antithrombotic treatment to minimize the risk of embolization is of paramount importance. Advanced imaging techniques are often required to establish the diagnosis of this condition.

OnBehalf Nicosia General Hospital We present the case of a young patient with large B-cell lymphoma causing severe extrinsic pulmonary stenosis. This patient presented to the emergency department with chest discomfort ,fatigue and dyspnea on minimal exertion. A loud ejection mid-systolic crescendo-decrescendo murmur with widely split S2 located in 2nd left parasternal border, raised the suspicion of pulmonary stenosis and patient underwent immediate transthoracic echocardiography as the first imaging modality of choice.On transthoracic echocardiography a large mass was seen, causing severe extrinsic pulmonary stenosis, and was further diagnosed as B-cell lymphoma after CT-guided biopsy. We discuss the high index of lymphoma suspicion in cases of pulmonary stenosis findings such as loud ejection murmur in pulmonic valve auscultation area, in otherwise healthy patients, with no history of congenital heart disease. Lymphoma and other mediastinal masses represent the most common aetiology of acquired pulmonary stenosis and should be suspected in otherwise healthy patients who present with clinical findings of pulmonary stenosis and vice-versa, pulmonary stenosis should be suspected in the presence of symptomatic mediastinal masses.
