Article Synopsis
  • - The study analyzed 64 patients with small cell lung cancer (SCLC) to assess the expression of Delta-like ligand 3 (DLL3) and other neuroendocrine markers using immunohistochemistry and digital pathology tools; DLL3 was found expressed in 72.3% of patients.
  • - The majority of patients were older adults (median age over 71), and notable findings included high expression rates of ASCL1 (97%) and a potential new role for TTF-1 as a biomarker, as it was positive in half of the cases.
  • - The research highlights the variability of neuroendocrine marker expression in SCLC, suggesting that DLL3 could be a therapeutic target, while the

Background: To report a case of IgG4-related pachymeningitis presenting with cystic lesions mimicking neurocysticercosis.

Case Presentation: A 40-year-old female patient with tetraparesis, dysphagia and dysphonia was evaluated with clinical examination, magnetic resonance imaging, and meningeal biopsy. Magnetic resonance imaging (MRI) revealed diffuse pachymeningeal enhancement involving the cranial, cervical, thoracic, and lumbar segments with spinal cord compression and cystic lesions.

Unlabelled: Bladder cancer is the most common malignancy in the urinary tract, and is biologically and clinically quite heterogeneous. Around 90% of diagnoses are made in the 6 decade, being more prevalent in males. The programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) axis play a putative role in immune checkpoint and as a means through which cancer evades the immune system.

Background: Glycogen Synthase Kinase-3 beta (GSK-3β) regulates diverse cell functions including metabolic activity, signaling and structural proteins. GSK-3β phosphorylates target pro-oncogenes and regulates programmed cell death-ligand 1 (PD-L1). This study investigated the correlation between GSK-3β expression and clinically relevant molecular features of lung adenocarcinoma (PDL1 score, PTEN expression and driver mutations).

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare idiopathic inflammatory disease that mainly affects children and young adults. The clinical signs and symptoms are nonspecific, hindering and delaying the proper diagnosis. We report a case of CRMO in a child with chronic pain in the cervical and thoracic spine.

Therapies targeting EGFR are effective in treating tumors that harbor molecular alterations; however, there is heterogeneity in long-term response to these therapies. We retrospectively analyzed protein expression of EGFR, Stat3, phospho-Akt, and phospho-Erk1/2 by immunohistochemistry in a series of resected cases from a single institution, correlated with clinicopathological variables. There were 96 patients, with the majority of cases being of low stage tumors (17 pT1a, 23 pT1b, 30 pT2a, and 18 pT2b).

Purpose: The study evaluates the clinical and pathological findings of 16 patients with locally advanced penile carcinoma (PC) submitted to emasculation, and discusses questions related to the usefulness of bilateral orchiectomy.

Materials And Methods: Between 1999 and 2010, 172 patients with PC were treated. Sixteen (9 %) underwent emasculation.

Rosai-Dorfman disease is a self-limiting condition caused by histiocyte proliferation within the sinusoids of lymph nodes and in extranodal tissue. It is a rare disease, particularly in children, that progresses with extensive lymphadenopathy. This paper reports on the case of a 2-year-old child with progressive cervical lymphadenopathy associated with persistent fever and radiological findings suggestive of lymphoma.

The neuronal ceroid lipofuscinoses (NCL) are a group of neurodegenerative disorders, characterized by abnormal storage of an autofluorescent substance of lipopigments, resembling ceroid and lipofuscin, within lysosomes of neurons and other types of cells. The main phenotypic subtypes have been established on the basis of age of onset, clinical course, and ultra structural morphology, and classified as infantile, late infantile, juvenile and adult forms. Six genes have been associated with human NCL and approximately 150 mutations have been described.
