Hemangioma originating from the main pulmonary artery.

In this study, we report the case of a 42-year-old female patient who was diagnosed with hemangioma in the pericardium connected to the main pulmonary artery. Chest CT revealed a hypodense, well-marginated, mass-like lesion, probably connected to the main pulmonary artery, and multiple heterogeneous attenuations were seen with contrast enhancement. The tumor was resected using conventional extracorporeal circulation for complete resection involving the main pulmonary artery wall.

Gastroenteropancreatic-origin neuroendocrine carcinomas: Three case reports with favorable responses following localized radiotherapy and a review of literature.

Rationale: The radiotherapy (RT) responses of gastroenteropancreatic (GEP)-origin neuroendocrine tumors remain unclear. We report cases of favorable response after localized RT of GEP-origin neuroendocrine carcinomas (GEP-NECs).

Patient Concerns: 1.

Thymic carcinoma initially presented with geographic destruction of scapula in a child.

As the conventional histopathologic examination of thymic carcinoma (TC) is nonspecific, immunohistochemical studies along with correlative radiographic investigations are needed for its correct diagnosis. TC commonly occurs in the late 5th to early 6th decades of life but is extremely rare in childhood. It may be incidentally detected from chest radiographs taken as routine or for other reasons.

Huge tophaceous pseudogout associated with tenosynovial chondromatosis arising from flexor digitorum tendon sheaths of the foot: a case report.

Synovial chondromatosis (SC) is a benign proliferative process of synovial tissue creating multiple cartilaginous nodules in joints. It most commonly occurs in the large joints of the knee, hip, and shoulder, uncommonly in the small joints of the hand and foot, and only rarely in the tenosynovial membrane of tendon sheath, termed tenosynovial chondromatosis (TC). Unlike SC, TC predisposes to the foot or hand.

Primary cutaneous Ewing's sarcoma/primitive neuroectodermal tumor manifesting numerous small and huge ulcerated masses: its complete remission by chemotherapy and magnetic resonance imaging findings.

Extraskeletal Ewing's sarcoma (ES) and primitive neuroectodermal tumor (PNET) are widely regarded as clinically and histologically identical tumors which consist of small blue round cells. Extraskeletal ESs/PNETs usually occur in the deep soft tissues of the paraspinal region, chest wall, or lower extremities. However, superficially located cases, so-called cutaneous ESs/PNETs, are exceedingly rare, and the vast majority of the reported cases present as a single small mass.

The increased expression of matrix metalloproteinases associated with elastin degradation and fibrosis of the ligamentum flavum in patients with lumbar spinal stenosis.

Background: One of the characteristics of spinal stenosis is elastin degradation and fibrosis of the extracellular matrix of the ligamentum flavum. However, there have been no investigations to determine which biochemical factors cause these histologic changes. So we performed the current study to investigate the hypothesis that matrix metalloproteinases (MMPs), which possess the ability to cause extracellular matrix remodeling, may play a role as a mediator for this malady in the ligamentum flavum.

Chromomycosis presenting as soft-tissue mass: report of a case with MRI features.

Chromomycosis is primarily a skin disease that superficially presents as slowly growing, verrucous lesions, often warty or cauliflower-like in appearance. It may occasionally create a flat, plaque-like lesion in the skin but deep-seated tumorous presentation has not previously been reported. As the lesion is limited to the cutaneous and superficial subcutaneous tissues, hitherto reported cases have been described from the view point of dermatology and, so, without MRI study.

Lipoma arborescens of the glenohumeral joint: a possible cause of osteoarthritis.

Lipoma arborescens is a very rare intra-articular lesion characterized by villous lipomatous proliferation of the synovium, usually involving the knee joint. To date, in the literature, there has been only one reported case of lipoma arborescens in the glenohumeral joint. But, the authors treated the patient conservatively and reported only the magnetic resonance imaging (MRI) findings.

The immunoexpressions and prognostic significance of inhibin alpha and beta human chorionic gonadotrophins (HCG) in breast carcinomas.

Purpose: Pregnancy and hCG treatments are considered essential for inhibiting breast cancer. The effect of hCG is accompanied by the synthesis of inhibin, a transforming growth factor involved in cell differentiation and proliferation. Inhibin is considered a tumor suppressor, but its role in the breast is unclear.

Prevalence of decreased susceptibility to carbapenems among Serratia marcescens, Enterobacter cloacae, and Citrobacter freundii and investigation of carbapenemases.

Between March and July 2002, total of 612 clinical isolates of Serratia marcescens, Enterobacter cloacae, and Citrobacter freundii (201 S. marcescens, 228 E. cloacae, and 183 C.

Hyalinizing spindle cell tumor with giant rosettes with pulmonary metastasis after a long hiatus: a case report.

Hyalinizing spindle cell tumor with giant rosettes (HSCTGR) is a recently described tumor, which is regarded as an unusual variant of low-grade fibromyxoid sarcoma. Proof of a metastatic potential was lacking. The patient in the report was a 35-yr-old woman who showed multiple bilateral pulmonary nodules with massive pleural effusion in the right side.

HER-2/neu oncogene amplification by chromogenic in situ hybridization in 130 breast cancers using tissue microarray and clinical follow-up studies.

Determining of HER-2/neu oncogene amplification has become clinically important for managing breast cancer. Fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) are currently regarded as the standard methods. Chromogenic in situ hybridization (CISH) was investigated as a new modification with an accurate, sensitive technique.
