Mixed Neuroendocrine—Non‐Neuroendocrine Neoplasm (MiNEN) of the Gallbladder. A Case Report From a Low‐Resource Setting

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT Mixed neuroendocrine–non‐neuroendocrine neoplasms (MiNENs) of the gallbladder are exceedingly rare entities. We report a case of a 35‐year‐old female with a palpable right hypochondrial mass. Imaging demonstrated a large polypoid gallbladder lesion with periportal lymphadenopathy. The patient underwent open cholecystectomy with lymphadenectomy.

Long‐Term Survival Following Nivolumab Treatment in Pulmonary Tumour Thrombotic Microangiopathy Associated With Cancer of Unknown Primary: A Case Report

Respirology Case Reports, Volume 14, Issue 10, October 2026.
Pulmonary tumour thrombotic microangiopathy (PTTM) is a rapidly fatal condition that is rarely diagnosed during life. Early clinical recognition and prompt nivolumab treatment resulted in long‐term survival in a patient with cancer of unknown primary‐associated PTTM.

Clinical and therapeutic aspects of extrapulmonary small cell carcinoma

, 2009
Extrapulmonary small cell carcinoma (EPSCC) is usually treated similarly to small cell lung cancer. Differences in aetiology, clinical course, frequency of brain metastases, and survival, however, warrant a differential therapeutic approach.

The Bird's Nest Sign as an Initial Presentation of Primary Pulmonary B‐Cell Non‐Hodgkin Lymphoma With Plasmacytic Differentiation

Respirology Case Reports, Volume 14, Issue 10, October 2026.
We report a rare case of primary pulmonary B‐cell non‐Hodgkin lymphoma with plasmacytic differentiation presenting with bird's nest sign, mimicking an invasive fungal disease at first. This case highlights the importance of considering lymphoma in the differential diagnosis when infection is excluded and concurrently seeking a confirmatory diagnosis ...

Primary Small Cell Carcinoma of the Kidney: Disease Characteristics and Treatment Outcomes

Medicines, 2021
Background: Primary small cell carcinoma of the kidney (PSCCK) is exceedingly rare and data on disease characteristics and outcomes are sparse. This study examines a nationally-representative cancer registry to better characterize PSCCK.

Lung Metastases of Pancreatic Adenocarcinoma Masquerading as Temporary Improvement of Bilateral Diffuse Lung Opacities Following Treatment for Interstitial Lung Disease

Respirology Case Reports, Volume 14, Issue 10, October 2026.
A 75‐year‐old man was referred to our department with ground‐glass opacities (GGOs) and consolidation in both lungs on computed tomography. After an initial response to cyclophosphamide therapy, he returned with worsening dyspnea and was ultimately diagnosed with pulmonary metastases from pancreatic adenocarcinoma.

Genomic Evolution and Immune Contexture With Therapeutic Relevance in Pancreatic Neuroendocrine Neoplasms

Cancer Science, Volume 117, Issue 10, Page 2619-2635, October 2026.
Lineage‐dependent immunogenomic landscapes and biologically informed therapy in pancreatic neuroendocrine neoplasms. Pancreatic neuroendocrine neoplasms display lineage‐dependent immunogenomic landscapes, in which genomic alterations, epigenetic states, antigen‐presentation status, immune‐cell infiltration, and suppressive microenvironments co‐evolve ...

Genetic intratumour heterogeneity in digestive high‐grade neuroendocrine neoplasms

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Intratumour heterogeneity in digestive high‐grade neuroendocrine neoplasms. Abstract Digestive high‐grade neuroendocrine neoplasms (HG‐NEN) are rare and heterogeneous tumours with an aggressive biology and limited treatment efficacy. Genetic intratumour heterogeneity (ITH) is a mechanism of progression and treatment resistance in other cancers, yet ...
