There cases of paediatric inflammatory myofibroblastic tumours in different locations are presented. This a rare benign disease, that can develop into malignant forms. Clinical features are associated with the location. Fever was the main symptom in all our cases. The symptoms that indicated the location of the tumour were, haematemesis in the first case, and respiratory disease in the third. In the third case our patient was diagnosed with tuberculosis due to mycobacterium avium. All cases had increased CRP, ESR, thrombocytosis and high levels of gamma globulins Surgery is curative if total resection is possible, and the diagnosis is made by histopathology. We would like to emphasise the early development in the second case as this was a 3 months-old infant.

Background: Soft tissue tumors (STTs) in adolescents are relatively rare, and their characteristics and behavior have not been well studied in this age group. The aim of this study was to describe the clinicopathologic patterns of STTs in adolescents aged 10-19 years according to the 2020 WHO classification.
Method: A 10-year retrospective cross-sectional study of 632 surgical samples from adolescents was conducted at a tertiary health facility to determine the frequency, histological patterns and characteristics of STTs in this population.

Renal pseudotumors, which mimic tumors on imaging, pose diagnostic challenges that can lead to unnecessary interventions. Sensing ultrasound localization microscopy (sULM) is an advanced imaging technique that uses ultrasound imaging and microbubbles as sensors to visualize kidney functional units. This study aims to investigate whether sULM could differentiate between renal pseudotumors and tumors based on the presence of glomeruli.

A 40-year-old woman presented with a mass in her OS for 2 years. Examination revealed a large conjunctival lesion on the nasal bulbar conjunctiva OS and a small upper tarsal conjunctival lesion in the OD. Biopsy OD revealed inflammatory granulation tissue, and OS revealed pseudoepitheliomatous hyperplasia with granulation tissue.

Neutrophils are the most abundant cell type in the airways of tuberculosis patients. Mycobacterium tuberculosis (Mtb) infection induces the release of neutrophil extracellular traps (NETs); however, the molecular regulation and impact of NET release on Mtb pathogenesis are unknown. We find that during Mtb infection in neutrophils, PAD4 citrullinates histones to decondense chromatin that gets released as NETs in a manner that can maintain neutrophil viability and promote Mtb replication.

We present the case of a 10-year-old male with a year-long history of low back pain, constipation, and difficulty in urination. MRI revealed an intradural extramedullary lesion at L5-S1, initially suspected to be a schwannoma or neurofibroma.
