Efficacy of Core Needle Biopsy in the Diagnosis of Pediatric Extracranial Solid Malignancies: A 10-Year Study.

Introduction: Core needle biopsies of solid masses in children are a minimally invasive technique. It guides to a definitive diagnosis and facilitates management.

Aims And Objectives: To determine the accuracy, sensitivity, and specificity of core needle biopsies in diagnosing pediatric solid masses.

Pilomatricomas and café au lait macules as herald signs of constitutional mismatch repair deficiency (CMMRD) syndrome-A case report.

Constitutional mismatch repair deficiency (CMMRD) syndrome results from bi-allelic mutations in DNA mismatch repair genes-MLH1, MSH2, MSH6, or PMS2. We present two siblings with CMMRD having p.Arg802Ter (c.

Time required for effective action of phenol against giant cell tumour cells.

Purpose: To evaluate the time required for effective action of phenol against the giant cell tumour (GCT) cells.

Methods: Fresh GCT cells were harvested from 9 patients with primary GCT of the distal femur (n=4), proximal tibia (n=4), and proximal humerus (n=1), with the Campanacci tumour grades 3 (n=6), 2 (n=2), and 1 (n=1). Specimens were immersed in 80 % phenol for one, 3, 6, and 10 minutes, and were assessed by a single pathologist for irreversible cell death and the depth of phenol penetration.
