Cytomorphology and Molecular Profile of Hyalinizing Clear Cell Carcinoma of the Lung: A Case With Mucinous Differentiation

Diagnostic Cytopathology, Volume 54, Issue 7, Page E165-E169, July 2026.
ABSTRACT Hyalinizing clear cell carcinoma (HCCC) of the lung is an exceedingly rare salivary gland‐type neoplasm with limited cytomorphologic description. We report a case highlighting these features. A 3 mm incidental left‐airway lesion enlarged to 7 mm over 5 months, prompting radial endobronchial ultrasound (EBUS)‐guided transbronchial biopsy. Touch

Malignant craniopharyngiomas: Institutional experience and literature review

Brain Pathology, Volume 36, Issue 4, July 2026.
We report the second case of malignant craniopharyngioma with BAP1 and TP53 mutations. A literature review identified 44 cases of malignant craniopharyngiomas with a median overall survival of 6 months. Eighteen (41%) occurred in patients without any history of radiation, suggesting that mechanisms other than radiation have contributed to their ...
