Regression of Cardiac Lymphoma With Chemotherapy.

A patient was admitted for chest pain with electrocardiographic changes, and cardiac magnetic resonance showed focal myocardial hypertrophy secondary to edema. Combined positron emission tomography and computed tomography corroborated foci of myocardial hypermetabolism, as well as multiple adenopathies consistent with lymphoma in the biopsy. Hypertrophy and edema regressed with chemotherapy.

Updated Review and Clinical Recommendations for the Diagnosis and Treatment of Patients with Retroperitoneal Sarcoma by the Spanish Sarcoma Research Group (GEIS).

Soft tissue sarcomas (STS) are an uncommon and biologically heterogeneous group of tumors arising from mesenchymal cells. The incidence is estimated at five cases per 100,000 people per year. Retroperitoneal sarcomas (RPS) account for 10-15% of all STS, and their management depends on their anatomical characteristics and histotype.

The Phosphorylation of Kv1.3: A Modulatory Mechanism for a Multifunctional Ion Channel.

The voltage-gated potassium channel Kv1.3 plays a pivotal role in a myriad of biological processes, including cell proliferation, differentiation, and apoptosis. Kv1.

[Giant cell tumour of bone in the rib cage treated with denosumab. A case report].

Giant cell tumour of bone (GCTOB) accounts for 4-5% of all primary bone tumours and occurs most frequently in females between 20 and 45 years old. It is found in the epiphyses of the long bones, vertebral bodies and flat bones. We report the case of a 31-year-old woman who presented with a one month history of thoracic pain.

A Novel Gene Fusion in Solitary Fibrous Tumor: A Case Report.

Solitary fibrous tumor is a rare subtype of soft-tissue sarcoma with a wide spectrum of histopathological features and clinical behaviors, ranging from mildly to highly aggressive tumors. The defining genetic driver alteration is the gene fusion , resulting from a paracentric inversion within chromosome 12q, and involving several different exons in each gene. STAT6 (signal transducer and activator of transcription 6) nuclear immunostaining and/or the identification of gene fusion is required for the diagnostic confirmation of solitary fibrous tumor.

Net-like superficial lymphatic malformation.

The net-like superficial lymphatic malformation (LM) is a newly described entity with distinctive clinical, dermoscopic, and histologic characteristics. Clinical picture consists of red to purplish macules with a finely reticulated pattern of vascular structures. Dermoscopy shows arborizing telangiectatic vessels.

[Nephrotic proteinuria in hypertensive nephrosclerosis: clinical and evolution characteristics].

Background And Objective: Nephrotic range proteinuria can occur in patients with biopsy proven hypertensive nephrosclerosis (HN). We analysed the differential clinical and evolution characteristics of these patients compared with other glomerular diseases.

Material And Method: This is a case-control descriptive analysis obtained from the renal pathology registry of our hospital.

Gastrointestinal stromal tumors: experience in 49 patients.

Introduction: Gastrointestinal stromal tumours (GIST) are mesenchymal tumours of the digestive tract originated in the interstitial cells of Cajal. They express the tyrosine kinase c-kit (CD117) activity receptor. Mutations in this receptor cause neoplastic development.
