Introduction: Myofibroblastic tumours or pulmonary pseudotumours are rare and, though benign, they may become invasive and recur after excision.
Case Report: We report the case of a child aged 14, presenting with mild haemoptysis, who had a solitary nodule at the base of the left lung. CT scanning suggested a hypervascular tumour. Fibreoptic bronchoscopy was normal and it was not possible to perform percutaneous biopsy on account of its proximal situation. A lobectomy was performed via a postero-lateral thoracotomy with a successful outcome. Histological examination revealed a myofibroblastic tumour.
Conclusion: Recourse to primary surgery is essential to confirm the diagnosis of a myofibroblastic pulmonary tumour. Complete resection is the only guarantee to prevent recurrence.

Primary bronchial leiomyosarcoma: a diagnostic challenge.
BMC Pulm Med
January 2025
Department of Pathology, Affiliated Hospital of Zunyi Medical University, Zunyi City, Guizhou Province, P.R. China.
Background: Pulmonary bronchial leiomyosarcoma is an extremely rare malignant tumour of the lung originating from the mesenchymal tissue. The retroperitoneal region is the most common site of leiomyosarcoma. It exhibits a high degree of malignancy and a poor prognosis, thereby highlighting the significance of early diagnosis of this disease.

Introduction: The purpose of this study was to evaluate the association between body composition, overall survival, odds of receiving treatment, and patient-reported outcomes (PROs) in individuals living with metastatic non-small-cell lung cancer (mNSCLC).
Methods: This retrospective analysis was conducted in newly diagnosed patients with mNSCLC who had computed-tomography (CT) scans and completed PRO questionnaires close to metastatic diagnosis date. Cox proportional hazard models and logistic regression evaluated overall survival and odds of receiving treatment, respectively.
The role of tribbles homolog 2 in cell proliferation.
Cell Commun Signal
January 2025
School of Medicine, Southeast University, Nanjing, Jiangsu, China.
Tribbles homolog 2 (TRIB2), a pseudoserine/threonine kinase, is a member of the TRIB family. TRIB2 primarily regulates cell proliferation through its scaffold or adaptor effect on promoting the degradation of target proteins by E3 ligase-dependent ubiquitination and regulating mitogen-activated protein kinase (MAPK) and protein kinase B (AKT) signaling pathways. TRIB2 is not only involved in the physiological proliferation of cells (granulosa cells, myoblasts, naive T cells, and thymocytes) during normal development but also in the pathological proliferation of vascular smooth muscle cells and a variety of cancer cells (lung cancer cells, liver cancer cells, leukemia cells, pancreatic cancer cells, gastric cancer cells, prostate cancer cells, thyroid cancer cells, cervical cancer cells, melanoma cells, colorectal cancer cells, ovarian cancer cells and osteosarcoma cells) under disease conditions.

Background: Muscle-invasive bladder cancer (MIBC) is a prevalent cancer characterized by molecular and clinical heterogeneity. Assessing the spatial heterogeneity of the MIBC microenvironment is crucial to understand its clinical significance.
Methods: In this study, we used imaging mass cytometry (IMC) to assess the spatial heterogeneity of MIBC microenvironment across 185 regions of interest in 40 tissue samples.
A rare case of FH-deficient renal cell carcinoma with signet ring cells features.

Fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) is a clinically aggressive tumor with high rates of progression and mortality. A wide range of morphological variations has been observed in FH-deficient RCC, initially described as type 2 papillary RCC or unclassified RCC. Here, we report a case of FH-deficient RCC with rare signet ring cells features.
