Spatial Atlas of Small Cell Lung Carcinoma Reveals Intratumoral Tumor‐State Heterogeneity and an MMP12+ Macrophage Niche

Cancer Science, EarlyView.
Spatial transcriptomic profiling of SCLC revealed marked intratumoral heterogeneity, including coexisting neuroendocrine and non‐neuroendocrine states and spatially heterogeneous hypoxia, and identified an MMP12+ macrophage population enriched at hypoxic and necrotic tumor interfaces.

Out of the Ordinary, but Not Out of the Question: Atypia in Pancreatic Lesions Is Not Always Carcinoma

Cytopathology, EarlyView.
An incidental pancreatic lesion in a 69‐year‐old woman was sampled by EUS‐guided fine‐needle biopsy. Integrated cytopathological and histopathological evaluation with immunochemical staining supported organ‐preserving surgery. ABSTRACT Pancreatic perivascular epithelioid cell tumours (PEComas) are exceptionally rare mesenchymal neoplasms.

Merkel cell carcinoma: an updated guide for pathologists

Histopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.

Novel and emerging skin carcinomas and adnexal tumours

Histopathology, EarlyView.
The present review aims to provide an overview of the main emerging skin epithelial tumours, with particular emphasis on salivary gland analogue sweat gland tumours and poorly differentiated carcinomas. Epidermal and adnexal tumours of the skin constitute a complex and heterogeneous group of neoplasms, with distinct morphology and behaviour.

Whole‐slide analysis of mitotic activity in melanoma reveals higher‐proliferation hotspots and distinct spatial patterns

Histopathology, EarlyView.
Whole‐slide analysis of melanoma identified higher‐proliferation mitotic hotspots than routine pathology assessment and revealed distinct spatial patterns of mitotic organization, highlighting the potential of computational mitosis mapping to provide insights beyond conventional mitotic counting.
