Pulmonary hyalinizing granuloma is a very rare benign condition. This study describes a case involving pulmonary hyalinizing granuloma in a 76-year-old man who presented with a solitary pulmonary nodule, determined through chest radiography and computed tomography, that mimicked primary lung cancer. To establish a definitive diagnosis, tumor resection was performed with histopathological analysis indicating pulmonary hyalinizing granuloma. Radiographic findings in previously reported cases showed that most patients had well-defined margins and usually bilateral, multiple lesions. In our case; however, the solitary ill-defined tumor mimicking lung cancer is an uncommon location for this rare condition.

Hormographiella aspergillata is a rare hyaline mold causing invasive fungal infection in humans, until the frequent use of antifungal prophylaxis in immunocompromised hosts. Due to the high mortality of H. aspergillata infection, early recognition and treatment are crucial.

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is a rare type of primary salivary gland-type tumor of the lung. HCCC is characterized by unique pathological features, including nests, cords, or trabeculae of clear or eosinophilic tumor cells infiltrating a mucinous or hyalinized stroma. Additional analyses of this carcinoma have revealed positive epithelial markers via immunophenotyping and gene translocation through genetic testing.

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is an exceedingly rare tumor with unique clinicopathological features, posing major diagnostic challenges.
Case Presentation: We present a case of a 74-year-old woman with a lung nodule incidentally detected in the right middle lobe (RML) through F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) imaging. Through comprehensive evaluations by thoracic surgeons, she underwent video-assisted thoracic surgery of RML lobectomy to excise the lung nodule.

Abemaciclib, a cyclin-dependent kinase 4/6 inhibitor, is crucial in treating hormone receptor-positive, human epidermal growth factor receptor 2-negative metastatic or recurrent breast cancer. However, its association with drug-induced interstitial lung disease (DI-ILD) is concerning. We present an 82-year-old woman with breast cancer receiving abemaciclib, who developed persistent cough and malaise.

A new era in cancer therapy emerged with the arrival of immune-checkpoint inhibitors (ICIs), followed by a new cadre of immune-related adverse events that affect up to 40% of patients. Literature on the pathological features associated with these events is still limited. Therefore, to expand our knowledge of the histopathologic spectrum of pulmonary changes, we conducted a case study series analysis on 16 non-neoplastic lung samples collected during or after ICI therapy.
