DRESS Syndrome That Resembles Graft-Versus-Host Disease after Chemotherapy in a Pediatric Patient: A Case Report.

Introduction: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a potentially life-threatening, drug-induced adverse reaction characterized by skin eruptions, lymphadenopathy, fever, and a broad range of other bodily manifestations. The spectrum of histopathologic and clinical presentations is wide; therefore, DRESS syndrome can mimic other diseases.

Case Presentation: We present a case of a 4-year-old male patient who started chemotherapy with vincristine, cytarabine, and etoposide.

Helicobacter pylori culture as a key tool for diagnosis in Colombia.

Introduction: The presence of H. pylori in the stomach is associated with gastric pathologies. However, its diagnosis through culture methods is challenging because of its complex nutritional requirements and microaerophilic conditions for optimal growth.

Evaluation of Helicobacter pylori Infection and Clarithromycin Resistance in Strains From Symptomatic Colombian Children.

The aim of the study was to determine the current prevalence of Helicobacter pylori in symptomatic Colombian children and evaluate the presence of mutations associated with clarithromycin resistance. Biopsies from 133 children were analyzed. The gastric fragment was used for urease test and reused for polymerase chain reaction sequencing of the 23SrDNA gene.

Hepatocellular carcinoma with both fibrolamellar and classical components: an unusual morphological pattern.

Fibrolamellar carcinoma (FLC) is an uncommon form of primary liver malignancy with unique clinical, histological, and biological characteristics. It is usually seen in young adults without underlying liver disease. Histologically, it shows large cells with abundant eosinophilic cytoplasm, large vesicular nuclei, prominent nucleoli, and lamellar type fibrosis.

Necrotizing encephalitis caused by disseminated Aspergillus infection after orthotopic liver transplantation.

Liver transplantation is the only available treatment for some patients with end-stage liver disease. Despite reduction in mortality rates due to advances related to surgical techniques, intensive medical management and immunosuppressive therapy, invasive fungal infections remain a serious complication in orthotopic liver transplantation. We report the case of an 18-year-old male diagnosed with autoimmune cirrhosis in 2009 who was assessed and listed for liver transplantation for massive variceal hemorrhage.

[Pathological and molecular diagnosis in a case of primary laryngeal tuberculosis in a physician].

Primary laryngeal tuberculosis is a rare disease with a wide variety of clinical manifestations. We report the case of an ear-nose and throat diabetic physician with primary laryngeal tuberculosis. The diagnosis of laryngeal cancer had been considered before in another institution, and at the patient's admission, he only presented dysphonia with a six-month evolution.
