Myoepithelial tumor of lung is a rare tumor; the histopathological findings resemble the myoepithelial tumors of the salivary gland. Distinguishing low-grade nonmetastatic myoepithelial carcinoma from benign myoepithelioma can be challenging both radiologically and histomorphologically. We present a case report of a low-grade myoepithelial carcinoma of lung with contralateral lung metastasis which was treated with low-dose external beam radiotherapy.

Background: Breast cancer (BC) is the most common cancer in women. Likewise, canine mammary tumors (CMT) represent the most common cancer in intact female dogs and develop in the majority spontaneously. Similarities exist in clinical presentation, histopathology, biomarkers, and treatment.

Myoepithelial cells (MECs) are known to play an active role in mixed mammary tumors and are found in dogs as well as in humans. The study aimed to assess the morphologic features of epithelial and mesenchymal cells and MECs and investigate their roles in epithelial-mesenchymal transformation in different tumor types in canine mammary tumors. Immunohistochemical staining was performed on 165 specimens from benign mixed tumors (BMT), carcinosarcomas, and simple carcinomas (SC).

Introduction: Pleomorphic adenoma is the most common neoplasm of the major salivary glands, and can undergo malignant transformation to carcinoma ex-pleomorphic adenoma (CXPA) in untreated patients.
Case Presentation: Our case describes a 56-year-old male with a 15-year history of slowly growing expansive right-sided neck. He underwent excision of the neck mass, neck dissection, and pectoralis flap reconstruction.

Aims: Although molecular tests developed for a growing list of oncogenic alterations have significantly aided in the classification of head and neck carcinomas, tumours in which prototypical histologic and immunophenotypic features are lacking or only partially developed continue to pose diagnostic challenges. Searching for known diagnostic and therapeutic targets by clinical next-generation sequencing (NGS) assays can often lead to new discoveries.
Methods And Results: We present our institutional experience in applying targeted RNA NGS in 36 head and neck carcinomas that were morphologically difficult to classify between 2016 and 2023.

Myoepithelial carcinoma of bone is uncommon. We presented the imaging features of myoepithelial carcinoma of the left femur in a 61-year-old man on 18F-FDG PET/CT. Lytic bone destruction and the formation of a slightly low-density soft tissue mass extending to adjacent muscles with intense and circular FDG uptake were found on 18F-FDG PET/CT.
