Pulmonary collision tumors have been described as a special entity of synchronous multiple lung cancer. There have been no reports detailing the chronological changes in primary collision lung cancers on chest computed tomography. We report a case of ground-glass lung nodules gradually colliding with each other. The collision tumors of the lung were composed of minimally invasive adenocarcinoma and adenocarcinoma in situ with epidermal growth factor mutations. Immunohistochemically, the Ki-67 labeling indices were different in the 2 components. Ki-67 staining was useful to distinguish the 2 components. The 2 dominant ground-glass tumors grew slowly with radiologic and pathologic heterogeneity.
- Outbreak of Mycoplasmal Round Pneumonia in an Adult Population: a Case Series. [Journal Article]
- CRClin Respir J 2018 Nov 12
- CONCLUSIONS: This case series illustrates the diversity of clinical manifestations as well as imaging findings for mycoplasmal pneumonia, to which clinicians should pay more attention. Mycoplasmal round pneumonia should be included in differential diagnosis of multiple pulmonary nodules in adults in order to enable accurate clinical identification of disease and successful treatment and resolution.

- Pneumocardia and septic pulmonary embolism due to nongas-forming liver abscess: A case report. [Journal Article]
- MMedicine (Baltimore) 2018; 97(45):e13096
- CONCLUSIONS: KPLA is potentially fatal due to the associated serious metastatic complications. Attention must be paid not only to the primary focus of infection but also to infection of other organs. It is important to detect to diagnose the spread of infection accurately, in a timely manner, to improve the prognosis of this condition.

An 11-year-old cat presented with nasal discharge and lacrimation and was diagnosed with nasal lymphoma. Although the cat showed favorable progression after undergoing chemotherapy, CT imaging demonstrated enlarged pulmonary nodules caused by Toxoplasma gondii. Following the cessation of chemotherapy, the cat was prescribed clindamycin hydrochloride for toxoplasmosis treatment; however, the cat developed kidney lymphoma and died. No T. gondii organisms were observed in the whole body necropsy specimens. It is known that immunocompromised human patients, including those who undergo chemotherapy, are considered at risk for toxoplasmosis. However, the risk of developing toxoplasmosis in cats undergoing chemotherapy is currently unknown. Findings from this case report suggest that cats with chemotherapy-resistant pulmonary masses might have a T. gondii infection rather than metastatic disease.

Lung cancer is mostly characterized by a pulmonary solid mass on CT. In rare cases,patients do not have these typical manifestation but present with diffusely-distributed small nodules and pulmonary bullae,which can easily be misdiagnosed. A special case of lung adenocarcinoma was managed in our hospital from September 24th to December 19th in 2016. Under high-resolution CT,multiple nodules were seen in both lungs,mostly in the upper lungs,involving the pleura and interlobular fissures. Some nodules had cystic changes. A large bulla was seen in the left upper lung. Its wall was thickened with multiple nodules. Lung adenocarcinoma was pathologically confirmed.

Pulmonary fungal infections, which can be opportunistic or endemic, lead to considerable morbidity and mortality. Such infections have multiple clinical presentations and imaging patterns, overlapping with those of various other diseases, complicating the diagnostic approach. Given the immensity of Brazil, knowledge of the epidemiological context of pulmonary fungal infections in the various regions of the country is paramount when considering their differential diagnoses. In addition, defining the patient immunological status will facilitate the identification of opportunistic infections, such as those occurring in patients with AIDS or febrile neutropenia. Histoplasmosis, coccidioidomycosis, and paracoccidioidomycosis usually affect immunocompetent patients, whereas aspergillosis, candidiasis, cryptococcosis, and pneumocystosis tend to affect those who are immunocompromised. Ground-glass opacities, nodules, consolidations, a miliary pattern, cavitary lesions, the halo sign/reversed halo sign, and bronchiectasis are typical imaging patterns in the lungs and will be described individually, as will less common lesions such as pleural effusion, mediastinal lesions, pleural effusion, and chest wall involvement. Interpreting such tomographic patterns/signs on computed tomography scans together with the patient immunological status and epidemiological context can facilitate the differential diagnosis by narrowing the options.

Pancreatic metastasis is extremely rare, particularly from small-cell lung cancer (SCLC). Studies on the role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with liquid-based cytology (LBC) in the diagnosis of metastatic small-cell carcinoma in the pancreas have been rarely conducted. We report herein a case of pancreatic metastasis from SCLC diagnosed using EUS-FNA with LBC (ThinPrep). A 71-year-old man presented with chief complaints of hemoptysis and jaundice over the past 1 month. Lung & pancreas tumors with multiple liver nodules were detected on computed tomography. The aspirated material from the pancreas using EUS-FNA was prepared as a cytologic specimen with ThinPrep method, which revealed scattered and clustered "small blue cells" with scant cytoplasm and stippled chromatin with frequent apoptotic bodies. Immunocytochemical staining of the cellblock material revealed strong positivity for CD56 and thyroid transcription factor-1. Endobronchial biopsy for lung mass revealed nests of small, round, blue tumor cells with hyperchromatic nuclei showing salt and pepper chromatin, scant cytoplasm, and brisk mitotic activity. Therefore, a diagnosis of metastatic small-cell carcinoma to the pancreas with an extensive stage was finally made.
- Role of cytology and immunochemistry in diagnosis of metastatic malignancies in the lung: A critical appraisal. [Journal Article]
- DCDiagn Cytopathol 2018 Oct 24
- CONCLUSIONS: The approach to the diagnosis of metastatic tumors in the lung on cytology should be largely guided by the previous clinical history and comparison with previous tissue/cellular material if available.
