Hippo pathway disruption and YAP1 activation in anogenital papillary squamous intraepithelial lesion

open access: yesHistopathology, EarlyView.
Disruption of the Hippo Pathway with YAP1 activation is a consistent finding in papillary squamous intraepithelial lesions and may underlie their altered epithelial maturation and HPV E6/E7 expression patterns, providing new insight into the pathogenesis of this distinct low‐risk HPV‐associated lesion.

Merkel cell carcinoma: an updated guide for pathologists

open access: yesHistopathology, 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.

Poorly differentiated lung adenocarcinomas with concurrent ALK and CD30 expression: a diagnostic pitfall mimicking ALK‐positive anaplastic large‐cell lymphoma

open access: yesHistopathology, EarlyView.
Poorly differentiated lung adenocarcinomas with concurrent anaplastic lymphoma kinase (ALK) and CD30 expression closely mimic ALK‐positive anaplastic large‐cell lymphoma, creating a significant diagnostic pitfall. Accurate classification requires comprehensive integration of clinical, radiologic, morphologic, immunophenotypic and molecular findings ...

Dissecting Cellulitis and Hidradenitis Suppurativa: Two Diseases or One Follicular‐Occlusion Spectrum?

open access: yesInternational Journal of Dermatology, EarlyView.
Graphical abstract summarizing evidence that dissecting cellulitis of the scalp (DC) and hidradenitis suppurativa (HS) may represent site‐modified expressions of a shared follicular‐occlusion pathway, highlighting convergent clinical, histopathologic, and therapeutic features, the diagnostic‐context paradox, and the need for paired molecular studies ...
