Papillary Adenocarcinoma: A Rare Subtype of Lung Adenocarcinoma.

Papillary adenocarcinoma (PA) of the lung is a specific form of lung cancer characterized by papillary structures in tumor cells. This type of cancer is relatively rare and has distinct pathological and radiological features that differentiate it from other types of lung adenocarcinomas. Determining the specific subtype of adenocarcinoma is a crucial factor in the choice of chemotherapy treatment. Detecting PA is fundamental, as it has both prognostic and therapeutic implications for patients with lung carcinoma. In this paper, we discuss two cases of young patients diagnosed with PA of the lung. The cases we present are particularly intriguing due to the relatively young age of the patients.

A Young Woman Presenting With a Post-traumatic Tracheal Wound.

Tracheobronchial injury is a rare but potentially fatal occurrence, with most cases resulting from penetrating trauma or blunt and iatrogenic injury during medical procedures such as endotracheal intubation, bronchoscopy, or surgery. Early recognition of clinical symptoms can help stratify patient risk and guide management, though these symptoms are often non-specific. We report the case of a 42-year-old patient who presented with post-traumatic chest pain from a sharp object. Radiographic investigation revealed pneumomediastinum and significant subcutaneous emphysema, while bronchial fibroscopy confirmed a wound on the posterior surface of the trachea. The patient underwent surgery with an uneventful postoperative course. Follow-up radiographic evaluation three weeks later showed healing of the tracheal wound and good clinical improvement.

Low-grade fibromyxoid sarcoma arising in the mediastinum: Case report and review of the literature.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare tumor characterized by bland histological features and aggressive clinical course, it is a distinctive variant of fibrosarcoma with high metastasizing potential and sometimes a long interval between tumor presentation and metastasis, the most common anatomic locations of occurrence are the lower extremities, thorax, inguinal area, and upper limbs, Here, we present the case of a 29-year-old patient with a deceptively benign-appearing mass arising in the mediastinum that had been discovered on computed tomography, a biopsy under cervicotomy was performed and histopathological examination revealed low-grade fibromyxoid sarcoma. In conclusion, LGFMS can arise in the mediastinum, and physicians should consider this entity as a differential diagnosis in the presence of such mass.

Mini-invasive endoscopic approach to tracheal inflammatory myofibroblastic tumor in a young woman: A case report.

INTRODUCTION: Inflammatory myofibroblastic tumor (IMT) of the trachea is rare tumor mostly found in children and young adults. CASE REPORT: We report a case of a 28 year-old woman who presented chronic isolated coughing. Chest CT scan showed a tracheal tumor. Rigid bronchoscopy allowed the complete removal of the tumor, and histology confirmed the diagnosis of IMT. 12 months follow-up found no recurrence. DISCUSSION: IMT is a rare tumor exhibiting both benign and aggressive behaviour. The endoscopic approach of tracheal should be considered when there is a minimal tracheal wall invasion. CONCLUSION: Through this case, we want to emphasise the role of rigid bronchoscopy in the complete removal of endotracheal IMT.

Tracheal Hamartoma: A Case Report.

Hamartoma is the most frequently observed benign lung tumor, but its tracheal form is still exceptionally encountered. Cough, dyspnea, hemoptysis, and chest pain are all possible symptoms of tracheal hamartoma. The non-specific symptoms may also lead to a delayed diagnosis, and while the choice of treatment varies depending on the size and location of the lesion, conservative treatments remain strongly recommended. This report presents the case of a 57-year-old male who presented to our department with inspiratory dyspnea. Clinico-radiological data and bronchoscopy revealed a benign tracheal tumor of the lipomatous hamartoma type. The patient underwent a tumor resection by rigid bronchoscopy with satisfactory clinical results.

Report of Two Pulmonary Sarcomatoïd Carcinoma Cases With Highlights on the Computed Tomography Features.

Pulmonary sarcomatoïd carcinomas are a heterogeneous group of poorly differentiated non-small cell tumors with a sarcomatous component. On imaging, they appear as peripheral or central masses, sometimes excavated. We report two cases of pulmonary sarcomatoïd lung carcinoma. The first case involves a 73-year-old active smoker who presented with dyspnea. A computed tomography (CT) scan showed a large locally advanced left lower lobar tumor process. A CT-guided biopsy was performed and the histopathological examination concluded a pulmonary sarcomatoïd carcinoma. The second case involves a 52-year-old chronic smoker who presented with hemoptysis. CT pulmonary angiography showed an excavated right upper lobar tumor. Histologic work-up of the right upper lobectomy piece objectified a pulmonary sarcomatoïd carcinoma. Pulmonary sarcomatoïd carcinoma has a nonspecific appearance on imaging and should be a part of imaging differential diagnoses in front of a large, lobulated, highly invasive lung tumor with or without excavation.

Ectopic cervical thymoma with myasthenia gravis: a rare association.

Thymic masses are one of the most common tumors in the anterior mediastinum. Nevertheless, because the thymus originates in the third and fourth pharyngeal pouches and descends into the anterior mediastinum, ectopic thymic tissue may be found anywhere from the angle of the mandible to the superior mediastinum. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic thymic tissue trapped during the migration of the embryonic thymus and is often misdiagnosed as a thyroid tumor or other neck masses. Herein, we report an unusual case of ectopic cervical thymoma associated to myasthenia gravis (MG).

Accidental inhalation of scarf pin: Presentation and management.

BACKGROUND: The accidental aspiration of foreign bodies (FBs) is a rare occurrence in adults. However, inhalation of scarf pin is a phenomenon more and more common in the context of Muslim nations. The aim of our study was to describe the characteristics of this particular FB and illustrate the circumstances and consequences of inhalation. METHODS: This retrospective study involved patients with a history of scarf pin aspiration admitted to the Thoracic Surgery Department of Mohammed VI University Hospital Center, Oujda, Morocco, over a period of 10 years. Their main presentation, diagnosis, treatment, and outcome were analyzed. RESULTS: The average age of the 30 cases was 18 years (13-43). No antecedent was found in all cases. The penetration syndrome was found in all cases, with a transient moment of suffocation in 19 cases (63.33%), a dry cough in 15 cases (50%), minimal hemoptysis in 4 cases (13.33%), and purulent sputum in 3 cases (10%). The clinical examination was normal in all cases. The chest X-ray showed the FB in the form of linear right sided opacity in 14 cases (46.66%), left sided in 8 cases (26.66%), and in the trachea in 8 cases (26.66). Rigid bronchoscopy visualized the scarf pin at the level of the right basal pyramid in 5 cases (16.66%) and on the left side in 2 cases (6.66%), at the level of the main right and intermediate trunk in 7 cases (23.33%), at the level of the left main bronchus in 4 cases (13.33%) and in the trachea in 5 cases (16.66%). The pin was extracted by rigid bronchoscopy in 23 cases (76.66%) and was expelled spontaneously in 5 cases (16.66%). Thoracotomy was required in 2 cases (6.66%). Medical treatment, including antibiotic therapy and short-course oral corticosteroids, was administered in all cases. CONCLUSION: Scarf pin inhalation is common in women who wear the Islamic headscarf. Bronchoscopy is an important tool to manage these FBs, but the best prevention treatment is careful handling of these potentially sharp objects away from the mouth.

[Benign primitive schwannoma of the pleura]. / Schwannome bénin primitif de la plèvre.

Schwannoma is a neurogenic tumor originating from Schwann cells. When considering the thoracic region, it is most commonly found in the mediastinum. It commonly appears as a solitary lesion and pleural involvement is extremely rare. We here report the case of a 44-year old woman with benign primitive schwannoma of the pleura whose lesion was detected after radiological assessment for chest pain and dyspnea. The patient underwent complete surgical resection using video-assisted thoracoscopic surgery (VATS) technique. The anatomopathological study showed benign primitive schwannoma of the pleura.

Hydatid cyst of the pericardium mimicking a right atrial myxoma.

The hydatid cyst of the pericardium is a rare pathology; its clinical presentation is variable. It can reveal straightaway at the stage of life-threatening complications. Only a few cases of isolated pericardial hydatid cysts have been reported. Echocardiography, computed tomography, and magnetic resonance imaging are important diagnostic tools for the diagnosis of echinococcosis, and surgery remains the treatment of choice. Herein, we report a rare case of pericardial hydatid cyst who presented to our emergency department with complaints of palpitations, chest pain, and shortness of breath.
