AI Article Synopsis
- A 54-year-old man experienced left lower quadrant pain, and while a CT scan found no clear cause, it revealed a 2.0-cm lesion in his pancreatic tail.
- EUS-guided biopsy showed only benign tissue, leading to a 64 Cu-DOTATATE PET/CT scan that indicated the presence of a well-differentiated neuroendocrine tumor.
- However, surgery revealed focal chronic pancreatitis with islet aggregation, which mimicked a neuroendocrine tumor on the PET/CT scan.
Article Abstract
A 54-year-old man presented with left lower quadrant pain. CT showed no cause for his pain but identified an incidental 2.0-cm enhancing lesion in the pancreatic tail. On MRI, this lesion was hyperenhancing and diffusion-restricting, suspicious for a neuroendocrine tumor. However, EUS-guided biopsy yielded only benign pancreatic tissue. Due to this discordance, 64 Cu-DOTATATE PET/CT was performed. The pancreatic tail lesion was tracer-avid, suggesting a well-differentiated neuroendocrine tumor. Based on the PET findings, the patient underwent distal pancreatectomy. Surgical pathology revealed only focal chronic pancreatitis with islet aggregation, a previously undescribed mimic of neuroendocrine tumor on DOTATATE PET/CT.

Laparoscopic liver resection (LLR) is a minimally invasive surgical approach. Initially utilized for low-risk procedures, such as the resection of benign lesions, now LLR has evolved to include more complex operations such as metastatic lesions. We present in this article two cases with liver metastasis who underwent a successful two-stage total LLR: a 57-year-old man diagnosed with sigmoid cancer and liver metastasis and a 36-year-old man diagnosed with pancreatic neuroendocrine tumor and liver metastasis.

Prostate cancer (PC) progresses from benign epithelium through pre-malignant lesions, localized tumors, metastatic dissemination, and castration-resistant stages, with some cases exhibiting phenotype plasticity under therapeutic pressure. However, high-resolution insights into how cell phenotypes evolve across successive stages of PC remain limited. Here, we present the Prostate Cancer Cell Atlas (PCCAT) by integrating ∼710,000 single cells from 197 human samples covering a spectrum of tumor stages.

Primary small cell neuroendocrine carcinoma of the prostate is extremely rare, highly aggressive, and has a very poor prognosis, with an overall survival typically not exceeding one year. Standard treatment is generally based on the regimen for small cell lung cancer (SCLC), with guidelines recommending etoposide combined with cisplatin (EP regimen) as the first-line treatment. However, their therapeutic effects are limited.

Background: NF2-related schwannomatosis (NF2) is associated with various tumors of the central and peripheral nervous system. There is a wide range of disabilities these patients may suffer from and there is no validated clinical classification for disease severity. We propose a clinical classification consisting of three severity grades to assist in patient management.
