Charting the Unknown: Green Urine After Propofol in Pediatric Trauma.

The phenomenon of green urine discoloration, while rare, represents a captivating clinical puzzle that challenges the distinction between benign and pathological conditions. In this report, we present an intriguing case involving a 15-year-old trauma patient admitted following a motorcycle collision, where the ensuing unconsciousness necessitated propofol induction for intubation and sedation. Remarkably, around 48 hours post-admission, the patient displayed green urine discoloration, which resolved spontaneously within just 12 hours. This case serves as a compelling illustration of the uncommon occurrence of propofol-induced green urine in the context of critical care management, underscoring the imperative need to discern and appreciate medication-related chromatic alterations in urine.

Cough as a Clue: Tracheal Endocarcinoma Unveiled.

Tracheal adenocarcinoma (TAC) is a rare malignancy often characterized by significant delays in diagnosis, often attributed to the non-specific nature of symptoms, leading to subsequent challenges in management. The prognosis remains poor, highlighting the need for early detection and multidisciplinary treatment strategies. Surgical resection is recommended for eligible patients, followed by postsurgical irradiation. However, further research is required to give a better perspective on therapeutic interventions and enhance patient outcomes. This paper reports the case of a 50-year-old male, who presented with dyspnea, hemoptysis, and cough. The computed tomography (CT) revealed an intratracheal tissue mass. The cytological examination and immunocytochemistry confirmed the diagnosis of primary adenocarcinoma in the trachea. The treatment involved silicone tracheobronchial Y-stent followed by adjuvant chemotherapy with carboplatin and paclitaxel, and radiotherapy (60 Gray) with good clinical improvement.

Lung Sarcomatoid Carcinoma: An Intriguing Case Report of a Rare Malignancy.

Sarcomatoid carcinoma (SC) is a rare primary malignant tumor belonging to the group of non-small cell lung cancer (NSCLC). The diagnosis requires proper tumor sampling to exclude sarcoma, which is the main differential diagnosis. However, the prognosis of these tumors is poor, with a median survival rate lower than other NSCLC cases, mainly due to their aggressiveness and resistance to chemotherapy, especially platinum salts. In this report, we discuss a case of a 62-year-old male patient who presented at admission with hemoptysis and dyspnea. The diagnosis process involved thoracic computed tomography (CT) and fiberoptic bronchoscopy, which revealed tissue thickening at the carina and a mass extending from the lower end of the trachea to the carina, which was confirmed by biopsy. Unfortunately, despite receiving neoadjuvant radiotherapy and having endotracheal prosthesis, the patient succumbed to tumor progression. Our case highlights the aggressive nature of this tumor and underscores the importance of early detection.

Peroneal Tendon Dislocation: A Report of Two Cases.

Ankle injuries are a very common cause of patient visits to the primary care units and emergency departments. Although the most frequent ones are lateral ligament sprains, peroneal tendon subluxations have the same inversion mechanism and are described as one of the main causes of lateral ankle pain and instability. They are often missed during the acute phases as they are misdiagnosed as ankle sprains since both injuries share similar mechanisms and often occur in athletes and patients with high sports activity. We present two different cases of peroneal tendon dislocation that illustrate how this pathological condition may be present under different circumstances. We aim, through these cases, to provide clinical awareness and help improve earlier diagnosis of this condition; we also demonstrate the effectiveness of surgical reattachment of the upper retinaculum that two of our patients underwent.

Unusual Presentation of Embryonal Carcinoma of the Testis: A Case Report.

Embryonal carcinoma is a rare and aggressive type of non-seminomatous germ cell tumor that typically affects young to middle-aged individuals. It is often discovered by the patient or during routine medical exams as a painless or occasionally painful lump. Other revealing symptoms, such as lumbar pain or renal colic, are very uncommon in the literature. In this case report, we aim to highlight a case of embryonal carcinoma in a 21-year-old patient, which was discovered following the diagnostic workup of a left lumbar pain episode.

Hemiparesis Revealing a Unique Neurological Hemophagocytic Lymphohistiocytosis in a Patient With Griscelli Syndrome Type 2.

Griscelli syndrome (GS) is a rare genetic disorder that encompasses three different subtypes (GS type 1 (GS1), GS type 2 (GS2), and GS type 3 (GS3)), in which isolated neurological manifestations without immune system implications are typically seen in GS1, while neurological involvements in GS2 should be attributed to the macrophage and lymphocyte invasion of the central nervous system (CNS), under associated hemophagocytic lymphohistiocytosis (HLH). The presence of the clinical, biological, and hematologic features of HLH help explain the neurological defects that GS2 patients unusually present. In our case report, however, we attempt to highlight an uncommon presentation of GS2 involving a hemiparesis, along which we did not have any clinical or biological features of HLH. We also collect and evaluate similar published cases that feature this problem of explaining the neurological manifestations among GS2 patients.

Malignant Rhabdoid Tumor of the Kidney in a Child With Xeroderma Pigmentosum: Incidence or Coincidence?

Malignant rhabdoid tumor of the kidney (MRTK) is a rare aggressive malignant rhabdoid tumor that mainly affects children. At the onset of the disease, the usual clinical manifestations are gross hematuria, abdominal pain, and abdominal distension. The prognosis remains poor. Patients with rhabdoid tumors (RT) are treated according to institutional preferences that combine surgery, radiation therapy, and chemotherapy. The authors present the rare case of a child with xeroderma pigmentosum (XP) who presented with an abdominal mass accompanied by hematuria and abdominal pain. The radiological and histological results were congruent with the MRTK. The patient received preoperative chemotherapy but unfortunately died of septic shock. This case highlights the importance of being aware of MRTK and its fatal complications, as well as the increased risk of kidney tumors in patients with XP.

Cannonball Pulmonary Opacities Disclosing a Granulomatosis With Polyangiitis (GPA) With C-Antimyeloperoxidase (C-Anti-MPO) Antineutrophil Cytoplasm Antibodies (ANCAs).

Granulomatosis with polyangiitis (GPA) is a necrotizing granulomatous vasculitis of medium- and small-caliber vessels associated with the presence of antineutrophil cytoplasm antibodies (ANCAs) and antibodies specific for proteinase 3 (anti-PR3). The interest of this case lies on the fact that these antibodies are directed against myeloperoxidase revealed by the presence of scattered multiple pulmonary nodules. We report a 65-year-old-female patient who presented with a productive cough with mucus sputum associated with a cephalea for six months. The chest x-ray showed multiple pulmonary nodules, first suggesting a neoplastic origin. The initial etiological assessment was non-contributory. A month later, the patient developed pulmonary condensations and ocular signs. The etiological assessment then found ANCA anti-myeloperoxidase (anti-MPO)-GPA. A good knowledge of the clinical and radiological signs of GPA is important to quickly guide the diagnosis that will condition the prognosis of this disease.

Unexplained Pleural Effusion Leads to the Revelation of a Malignant Mesothelioma: A Case Report.

Malignant mesothelioma is a rare and aggressive cancer that usually affects subjects with prior asbestos exposure, a major risk factor that has been widely known as carcinogenic, and its use is now controlled if not banned in many areas of the world. Malignant mesothelioma originates from mesothelial surface cells covering the serous cavities, and the pleura is its most common site. Malignant pleural mesothelioma (MPM) typically presents with pleural effusion and chest wall pain with wide pleural thickening at radiological investigation. Although the histological examination along with immunohistochemistry helps yield the diagnosis, clinicians and experts face many challenges in diagnosing malignant mesothelioma not only due to the rarity of the disease but also due to the similarities that the disease share with other malignancies. Here, we report a case of a 55-year-old male patient with a history of chronic asbestos work exposure for 12 years who initially presented with unexplained pleural effusion and chest wall pain and was lost to follow-up but came back later with a worsening clinical state. This case is specially presented to raise awareness against cases of unexplained pleural effusion and chest pain.

What Lies Behind the Cannonball Pulmonary Metastases: Hodgkin's Lymphoma?

The cannonball pulmonary appearance is hematogenous dissemination of various primary tumors but rarely a Hodgkin's lymphoma, a disease that most commonly manifests with lymphadenopathy, often affecting the mediastinum and supraclavicular or cervical lymph nodes. To date, to the best of our knowledge, no case has been reported where the investigation of a cannonball pulmonary appearance led to the diagnosis of Hodgkin's lymphoma. Hence, in our case report, we attempt to highlight the uncommon presentation of this disease in a 14-year-old girl who initially presented with dyspnea before her chest x-ray revealed a cannonball pulmonary appearance, which was later linked with Hodgkin's lymphoma after performing a biopsy of her axillary node.
