AbstractAccording to diagnostic criteria, skin tumors can be divided into three categories: benign, low degree and high degree malignancy. For high degree malignant skin tumors, if not detected in time, they can do serious harm to patients ’ health. However, in clinical practice, identifying malignant degree requires biopsy and pathological examination which is time costly. Furthermore, in many areas, due to the severe shortage of dermatologists, it’s inconvenient for patients to go to hospital for examination. Therefore, an easy to access screening method of malignant skin tumors is needed urgently. Firstly, w...

CONCLUSION: Although rare, SCLs may arise from throughout the respiratory tract and cause dyspnea, hoarseness and stridor. Spindle cell lipoma should be considered in the differential diagnosis of a respiratory tract mass. This diagnosis confers a good prognosis and patients may be reassured that surgery is almost always curative. PMID: 31291740 [PubMed - as supplied by publisher]

Abstract The purpose of this study was to investigate the relationship between Lipoma preferred partner (LPP) gene polymorphisms and the risk of Immunoglobulin A nephropathy (IgAN) in the Chinese Han population. In this case-control study, we genotyped three single nucleotide polymorphisms (SNPs) of the LPP gene in 357 IgAN cases and 384 controls, using Agena Bioscience MassARRAY technology and assessed their association with IgAN using the χ2 test and genetic model analysis. The odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess risk and were adjusted for age and gender by logistic regre...

AbstractScalp lesions can be classified as congenital, traumatic, inflammatory, or neoplastic in origin. Although patients presenting with scalp masses are frequently seen in daily practice, differentiation of scalp lesions is often challenging for radiologists who are not familiar with the imaging of cutaneous lesions. The majority of scalp lesions are fortunately benign, with cystic lesions accounting for over 50% of all benign scalp lesions. Such lesions include trichilemmal cysts (pilar cysts), sebaceoma, epidermoid cysts, dermoid cysts, and teratoid cysts. Radiologists may also occasionally encounter benign neoplasms ...

We describe a case of new spinal mass causing CC, referred for radiotherapy for presumed malignancy, and ultimately proven via biopsy to be benign PDB. This is the first documented case of CC as the primary presentation of vertebral PDB mimicking malignancy. Suggested within is a diagnostic approach for unknown lesion causing CC that facilitates pathologic diagnosis while minimizing treatment delays.

Conclusion Primary tracheal tumors should be highly suspected in patients with recurrent and gradually worsening dyspnea; timely cervical, thoracic CT and bronchoscopy can provide an accurate diagnosis. Surgical radical resection is the only way to cure all benign tracheal tumors such as lipoma.

ConclusionGastric lipoma are a rare type of gastric submucosal tumors. Size is highly variable. Observation is a reasonable approach when small and asymptomatic, but multiple surgical modalities can be utilized to remove the tumor. Careful utilization of pre-operative imaging including EUS is critical in choosing the appropriate surgery if simultaneous bariatric management is undertaken

We present eight patients treated with wide resection (3 myxofibrosarcomas, 2 malignant melanomas, 1 spindle cell sarcoma, 1 basal cell carcinoma, and 1 exulcerated lipoma). No complications were observed using this technique. An intraoperative local control, confirmed histologically, was achieved in all patients. Tumor covering could help local tumor control at fungating tumor resection.
