Malignant transformation is a rare complication of the mature cystic teratoma of the ovary. Most of these histologic types are squamous cell carcinoma, and other types are exceptionally rare. Here, we present an extremely rare histology of malignant transformation, an undifferentiated carcinoma, arising in mature cystic teratoma of the ovary. A 48-year-old woman was referred due to abdominal distension and palpable pelvic mass. Computed tomography showed 16- and 12-cm-diameter mixed solid and cystic tumors in bilateral ovaries. Surgical exploration revealed bilateral ovarian tumors with multiple nodules on the whole peritoneum, liver capsule, and diaphragm. Cytoreductive surgery was performed, leaving less then 1 cm tumors. On pathologic review, the tumor was confirmed as undifferentiated with an adenosquamous carcinoma component arising in mature cystic teratoma. The patient died 7 days postoperatively due to uncontrolled malignant ascites and pleural effusion. We report a case of undifferentiated carcinoma arising from mature cystic teratoma, and we review the clinicopathologic features of this rare case.

Primary cardiac lymphoma (PCL) is a rare cardiac neoplasm. The most common type is diffuse large B-cell lymphoma, which mainly involves the right atrium and right ventricle. Its clinical manifestations are not specific. It is usually found late and the prognosis is poor. PCL is more common in immunodeficient patients. In view of the rarity of PCL, we have made a case report and a brief literature review.

We documented an elderly male patient with Burkitt's lymphoma diagnosed by echocardiography and percutaneous biopsy because of chest tightness. Chemotherapy was given to the patient, and the patient's condition was alleviated without recurrence.

Primary cardiac lymphoma is a highly malignant tumor. Early detection, diagnosis and treatment are crucial to the prognosis of PCL. At present, the most effective treatment is chemotherapy. There are more chemotherapy schemes and treatment methods worth studying.

Two cases of unilateral EF have been reported in the literature but were not related to strenuous physical activity. In this report, a young female presenting with unilateral scleroderma-like skin changes, blood and tissue eosinophilia, and hypergammaglobulinemia proven to be EF after strenuous physical activity is described. This case represents the first case reported in the current literature of unilateral EF after vigorous exercise. A skin to muscle biopsy and magnetic resonance imaging (MRI) study indicated classic EF features. Cases of unilateral eosinophilic fasciitis are under-recognized and have rarely been described in the literature. EF requires a high index of suspicion to be diagnosed accurately and differentiated from another scleroderma variant, especially localized types. Early diagnosis and management of unilateral EF are very crucial because EF management and prognosis are completely different from other scleroderma mimics. EF heals rapidly in response to glucocorticoid or combination therapy. In the current case, corticosteroids alone failed to induce complete disease remission, but with the addition of methotrexate, complete resolution of both skin and systemic features was obtained. She is now in good health with no medication use. The current literature review indicates that this the first reported case of unilateral EF after vigorous exercise.Interleukin-32 (IL-32) as a pro-inflammatory cytokine participates in the progression of inflammation and cancer. Ovarian cancer (OC) accounts for a considerable mortality rate, but research on IL-32 and OC is almost nil. Our study aims to explore the association between IL-32 and the progression as well as prognosis of OC initially. This hospital-based case-control study enrolled 147 OC patients and 337 healthy controls, and we used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method to distribute the genotypes. The results showed that the homozygous genotype (TT) of rs28372698 SNP was significantly higher in patients compared to controls (12.9% vs. 6.2%, P = 0.018, OR (95% CI) = 2.23 (1.16-4.29)). This revealed that TT genotype might be a risk factor in OC progression. This present study indicates that IL-32 gene polymorphism relates to an increased OC susceptibility, and IL-32 may be a marker for OC progression.This study aimed to investigate the use of fiberoptic bronchoscopy and bronchoalveolar lavage in the diagnosis of pulmonary pathogenic microorganism infection in AIDS patients. We retrospectively analyzed the clinical data, fiberoptic bronchoscopy and bronchoalveolar lavage fluid laboratory examinations of 209 AIDS patients with pulmonary infection. Among 209 patients, we found 42 cases of mycobacterial infection, 3 cases of bacterial infection, 58 cases of pneumocystis carinii pneumonia (PCP), 27 cases that were fungal positive, 99 cases of CMV, and 103 cases positive for GM test of which 83 cases were considered Aspergillus positive. BALF pathogen distribution was related to CD4+ T lymphocyte count. The primary pathogens of pulmonary infection in AIDS patients were cytomegalovirus, Mycobacterium tuberculosis, fungi, and Pneumocystis carinii. Fiberoptic bronchoscopy and bronchoalveolar lavage are important in the diagnosis of pathogenic microorganisms in lung infections of AIDS patients.Renal cell carcinoma (RCC) represents 90% of renal malignancies and is the most lethal neoplasm of the urologic system. RCC is not a single entity but rather a heterogeneous group of neoplasms with varying genetic, morphologic and clinical features and outcome. The aim of this study was to correlate pathologic features of RCC that can be helpful during the decision-making process. piperacillin We present a retrospective analysis of 249 RCCs (203 clear cell, 32 papillary and 14 chromophobe RCCs). We found that 77.8% of tumors of ≤4 cm and only 28.8% of RCC of >7 cm were limited to the kidney. The likelihood of lymphovascular invasion, fibrous renal capsule/perinephric fat/renal sinus fat, and vascular infiltration increased dramatically with increasing tumor size, particularly over 4.5 cm. Fat tissue was more often invaded through the renal sinus than through the renal capsule. Nuclear grade was significantly related to the pT stage, tumor size, percentage of necrotic area, lymphovascular invasion, fibrous renal capsule/perinephric fat/renal sinus fat and vascular infiltration.
