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.

Abstract Background. The authors report on an extremely rare case of skeletal muscle metastasis from primary lung cancer that involved the radial nerve and humerus, which was “overtreated” with wide tumor resection and frozen autograft reconstruction upon misdiagnosis of sarcoma by intraoperative frozen section, amid pressure of expediting hospital care during the COVID-19 pandemic. Case presentation. A 61-year-old male living outside Metro Manila presented with painful mass in his left distal arm during the enhanced community quarantine, and requested admission upon testing negative for COVID-19. Imaging studies suggested a diagnosis of soft tissue sarcoma involving the radial nerve and humerus, and intending to prevent nosocomial SARS-CoV-2 infection of patient, treatment was expedited by foregoing biopsy and opting for intraoperative frozen section prior to resection. Frozen section findings suggested malignancy intraoperatively, and we proceeded with wide tumor resection and frozen autograft reconstruction of the humerus using plates and screws. However, permanent sections revealed metastatic carcinoma from primary non-small cell lung cancer, with PET scan confirming lung mass in the right apical lobe. Conclusion. The report concludes that establishment of a definite tumor diagnosis by final histopathological analysis is indispensable, even when planning for emergent surgery in the time of COVID-19 pandemic.

Spontaneous pneumomediastinum (SPM) is a fairly rare condition, caused by increased intrathoracic pressure, leading to free air in the mediastinal structures. Underlying lung conditions are associated with increased incidence of SPM, including asthma, interstitial lung disease, pneumonia, bullous lung, and radiation therapy for lung cancer. It is often preceded by Valsalva maneuvers, vomiting, coughing, asthma exacerbation, sneezing, childbirth, or intense physical activity. A case of SPM is presented in a 15-year-old male, who complained of throat pain and dyspnea while running sprints at football practice. Workup revealed SPM, and he was subsequently admitted and treated conservatively. His symptoms resolved in 2 days and he was discharged and suffered no further recurrences. In contrast to secondary pneumomediastinum, SPM is usually a benign condition although life-threatening conditions can rarely arise. Differentiating between these two conditions has important prognostic indications. There is a paucity of prospectively collected data regarding SPM, and considerable variation in recommendations concerning the extent of workup.

Pseudoxanchoma elasticum (PXE) is an inherited disorder of connective tissue, characterized by calcification and degeneration of elastin. Clinical manifestations of PXE are protean, with skin, eyes and arteries being most commonly involved. Although often a benign condition, gastrointestinal hemorrhage is a potentially fatal complication. An unusual case of gastrointestinal hemorrhage in a patient with PXE is described and the pathophysiology, clinical presentation and complications of this rare condition are reviewed.

AbstractSoft-tissue metastasis refers to the growth of cancer cells originating from internal cancer in the soft tissues. In most cases, soft-tissue metastasis develops after initial diagnosis of the primary internal malignancy and late in the course of the disease. In very rare cases, they may occur at the same time or before the primary cancer has been detected. In our case, the soft-tissue metastasis and the primary lung cancer were diagnosed at the same time. To the best of our knowledge soft tissue metastasis on the anterior abdominal wall of unknown primary lung cancer is an extremely rare condition and only a handful of cases have been reported till date .We report a case of unsuspected soft tissue metastasis on the anterior abdominal wall of an unknown primary lung cancer with relevant discussion on the same.

Abstract Background: Multiple primary lung cancer is a rare type of tumor, which is necessary to differentiate from a metastatic tumor.Case presentation: We report a 67-year-old female with coughing and expectoration in the past eight days. Chest computed tomography revealed that there are two nodules in the patient's lung. Radiographic findings cannot distinguish between the two nodules and distinguish between primary and metastatic lesions.The patient underwent bronchoscopic biopsy and percutaneous lung puncture. Combined with morphological and immunohistochemical results, we concluded that this is a case of multiple primary lung cancers, consisting of adenocarcinoma and adenoid cystic carcinoma. In clinical practice, surgery is considered to be the first choice for the treatment of cases of multiple primary lung cancer. The patient received symptomatic treatment because of the metastases. Conclusions: The article aims to report a rare case and emphasize the role of immunohistochemistry in diagnosing multiple lung cancer.
