Extragonadal germ cell tumor presenting in a woman with systemic lupus erythematosus: a case report

Introduction

Esophageal intramural pseudodiverticulosis is a rare condition characterized by the dilatation of the submucosal glands.

Case presentation

We present a case of esophageal intramural pseudodiverticulosis in a 72-year-old Caucasian man who presented with dysphagia and with a background history of alcohol abuse. An upper gastrointestinal endoscopy of our patient showed an esophageal stricture with abnormal mucosal appearances, but no malignant cells were seen at biopsy. Appearances on a barium esophagram were pathognomonic for esophageal intramural pseudodiverticulosis.

Conclusion

We demonstrate the enduring usefulness of barium esophagography in the characterization of abnormal mucosal appearances at endoscopy.     

Group B streptococcus tricuspid endocarditis presenting with arthralgia in a postpartum woman: a case report

ABSTRACT: INTRODUCTION: Infective endocarditis presenting with arthralgia is rare. Group B streptococcus tricuspidendocarditis as a postpartum complication is even rarer. The present case is an example ofboth. CASE PRESENTATION: We report the case of a 30-year-old Caucasian woman who presented with painful swelling ofher wrists and ankles. CONCLUSION: Even when the clinical presentation of systemic inflammation is more suggestive of aprimary rheumatological disorder, it is important to remember that bacterial infection canalso present in this manner. Group B streptococcus tricuspid valve endocarditis is a rare, butrecognized, postpartum complication.     

A cervical ligamentum flavum cyst in an 82-year-old woman presenting with spinal cord compression: a case report and review of the literature

Introduction

Legionnaires' disease is recognized as a multi-systemic illness. Afflicted patients may have pulmonary, renal, gastrointestinal tract and central nervous system complications. However, renal insufficiency is uncommon. The spectrum of renal involvement may range from a mild and transient elevation of serum creatinine levels to anuric renal failure requiring dialysis and may be linked to several causes. In our present case report, we would like to draw attention to the importance of the pathological documentation of acute renal failure by reporting a case of a patient with acute tubulointerstitial nephritis complicating Legionnaires' disease.

Case presentation

A 55-year-old Caucasian man was admitted to our hospital for community-acquired pneumonia complicated by acute renal failure. Legionella pneumophila serogroup type 1 was diagnosed. Although the patient's respiratory illness responded to intravenous erythromycin and ofloxacin therapy, his renal failure worsened, he became anuric, and hemodialysis was started. A renal biopsy was performed, which revealed severe tubulointerstitial nephritis. After initiation of steroid therapy, his renal function improved dramatically.

Conclusions

This case highlights the importance of kidney biopsies in cases where acute renal failure is a complicating factor in Legionnaires' disease. If the presence of acute tubulointerstitial nephritis can be confirmed, it will likely respond favorably to steroidal treatment and thus irreversible renal damage and chronic renal failure will be avoided.     

Human immunodeficiency virus seroconversion presenting with acute inflammatory demyelinating polyneuropathy: a case report

Introduction

Electrocardiogram (ECG) abnormalities in patients with blunt chest trauma are diverse and non-specific, but may be indicative of potentially life-threatening conditions.

Case presentation

We report a rare case of pneumopericardium with extreme ECG abnormalities after blunt chest trauma in a 22-year-old male. The diagnosis was confirmed using computed tomography (CT) scanning. The case is discussed, together with its differential diagnosis and the aetiology of pneumopericardium and tension pneumopericardium.

Conclusion

Pneumopericardium should be distinguished from other pathologies such as myocardial contusion and myocardial infarction because of the possible development of tension pneumopericardium. Early CT scanning is important in the evaluation of blunt chest trauma.     

Rebound of relapses after discontinuation of rituximab in a patient with MOG-IgG1 positive highly relapsing optic neuritis: a case report

Background

Myelin oligodendrocyte glycoprotein immunoglobulin G1 (MOG-IgG1)-associated disease is suggested as a separate disease entity distinct from multiple sclerosis and neuromyelitis optica spectrum disorder. Nonetheless, the optimal treatment regimen for preventing relapses in MOG-IgG1-associated disease remains unclear.

Case presentation

We describe the case of a 45-year-old man with MOG-IgG1-positive highly relapsing optic neuritis who had experienced 5 attacks over 21?months and had monocular blindness despite prednisolone and azathioprine therapy. He began treatment with rituximab, which reduced the rate of relapse markedly. Following discontinuation of rituximab, however, the patient experienced two successive optic neuritis attacks 2 and 4?months after B-lymphocyte restoration.

Conclusions

Highly relapsing MOG-IgG1-associated disease can be prevented with rituximab even when the MOG-IgG1 titers are relatively stationary. Discontinuation of rituximab and restoration of B-lymphocytes may be associated with the rebound of disease activity.

     

Recurrent pregnancy loss in a subject with heterozygote factor V Leiden mutation; a case report

Recurrent pregnancy loss is usually defined as the loss of two or more consecutive pregnancies before 20 weeks of gestation, which occurs in approximately 5% of reproductive-aged women. It has been suggested that women with thrombophilia have an increased risk of pregnancy loss and other adverse pregnancy outcomes. Thrombophilia is an important predisposition to blood clot formation and is considered as a significant risk factor for recurrent pregnancy loss. The inherited predisposition to thrombophilia is most often associated with factor V Leiden mutation, prothrombin G20210A mutation, and methylenetetrahydrofolate reductase C677T and A1298C gene variants. The net effect is an increased cleavage of prothrombin to thrombin and excessive blood coagulation. Key Words: Recurrent pregnancy loss, Hereditary thrombophilia, Factor V Leiden mutation     

Fine-needle aspiration biopsy cytology of cutaneous calcinosis in a 74-year-old woman with dermatomyositis on methotrexate therapy: a case report

BACKGROUND: Cutaneous calcinosis (CC) occurs in a variety of rheumatic diseases. Fine needle aspiration biopsy (FNAB) may be used in the office setting to evaluate such soft tissue lesions. For patients on methotrexate (MTX) therapy, methotrexate nodulosis (MN) should be considered in the differential diagnosis. CASE: A 74-year-old Caucasian woman with adult-onset dermatomyositis (ADM) on MTX therapy presented for evaluation of a right breast mass and multiple soft tissue nodules. FNABs of the right breast mass and a left upper extremity nodule both demonstrated benign calcified material. Six months later, the patient returned for evaluation of the persistent right breast mass and repeat FNAB revealed adenocarcinoma. Concurrently, a right hip soft tissue nodule was aspirated, demonstrating benign crystalline debris. MTX therapy was discontinued, and the patient subsequently underwent a lumpectomy of the right breast 1 month after FNAB diagnosis, displaying infiltrative ductal carcinoma. Of note, 2 months after her lumpectomy, MTX therapy was restarted and the patient continues to have adequate control of ADM symptoms with persistent, clinically benign soft tissue calcifications. CONCLUSION: Performing FNAB on soft tissue lesions can obviate needless tissue biopsies of CC in appropriate rheumatology patients, thus avoiding the risks and complications associated with more invasive procedures.     

Primary angiitis of the central nervous system presenting with subacute and fatal course of disease: a case report

Background

Primary angiitis of the central nervous system is an idiopathic disorder characterized by vasculitis within the dural confines. The clinical presentation shows a wide variation and the course and the duration of disease are heterogeneous. This rare but treatable disease provides a diagnostic challenge owing to the lack of pathognomonic tests and the necessity of a histological confirmation.

Case presentation

A 28-year-old patient presenting with headache and fluctuating signs of encephalopathy was treated on the assumption of viral meningoencephalitis. The course of the disease led to his death 10 days after hospital admission. Postmortem examination revealed primary angiitis of the central nervous system.

Conclusion

Primary angiitis of the central nervous system should always be taken into consideration when suspected infectious inflammation of the central nervous system does not respond to treatment adequately. In order to confirm the diagnosis with the consequence of a modified therapy angiography and combined leptomeningeal and brain biopsy should be considered immediately.

     

Vaginal involvement in a woman with Darier's disease: a case report

BACKGROUND: Involvement of the female genital tract by Darier's disease, an unusual genodermatosis, is uncommon, and the manifestation of the disease in a cervicovaginal smear is exceptionally rare. CASE: A 39-year-old woman had an abnormal Pap smear caused by involvement of the female genital tract by Darier's disease. Cytologic examination showed features consistent with a low grade squamous intraepithelial lesion, but during a biopsy it was found to be vaginal involvement by Darier's disease. CONCLUSION: The correct interpretation of cytologic findings is not possible when the diagnosis of Darier's disease is not known since a low grade squamous intraepithelial lesion cannot be ruled out. This case underlines the importance of knowing the patient's medical histoiy in any moment of medical attention.
