IntroductionGanglioneuroblastoma is a rare peripheral neuroblastic tumor that is derived from developing neuronal cells of the sympathetic nervous system, and is found mostly, but not exclusively, in babies and young children.Case presentationTo the best of our knowledge, there have been no previously reported cases of ganglioneuroblastoma of the mediastinum from Pakistan. We present a case of ganglioneuroblastoma in an eight-year-old Pakistani Sindhi boy incidentally found to have a large posterior mediastinal mass that on biopsy initially looked like ganglioneuroma. He underwent successful excision of the mediastinal mass and remained stable post-operatively. Final pathology findings showed a ganglioneuroblastoma. He has remained free of symptoms on long-term follow-up.ConclusionsThe rarity of this tumor along with its almost exclusive occurrence in the pediatric population necessitates a thorough investigation of patients presenting with a symptomatic mass.
Background
Low-grade fibromyxoid sarcoma (LGFMS) is a rare tumor characterized by bland histological features and aggressive clinical course. The most common anatomic locations of occurrence are the lower extremities, thorax, inguinal area, and upper limbs. Primary mediastinal sarcomas are even rarer. To the best of our knowledge, only seven cases of primary mediastinal LGFMS have been reported in the literature. Here, we report a case of primary mediastinal LGFMS.
Case presentation
A 26-year-old Pakistani man presented with fever and vomiting for the past 2 months. On a routine chest x-ray, a mediastinal mass was incidentally found. Computed tomography (CT) scan showed a large circumscribed lobulated soft tissue density mass lesion in an anterior mediastinum. Grossly, the resected mass measured 17.0 × 12.0 × 11.0 cm. The cut surface was gray white with a whorled-like appearance and foci of calcification and cystic changes. Histologically, a spindle cell lesion was seen with alternating myxoid and hyalinized areas. The shaped cells were arranged in bundles. Immunohistochemical staining showed positive reactivity patterns with MUC4 and focally for epithelial membrane antigen (EMA). The diagnosis was confirmed as LGFMS. The patient is free of symptoms and recurrence 22 months after the surgery.
Conclusion
In conclusion, we report a rare case of primary mediastinal LGFMS in a young male patient that was discovered incidentally. Our patient is on regular follow-up to look for evidence of recurrence as these tumors are prone to recurrences.
Cervical necrotizing fasciitis (CNF) is a rapidly spreading deep neck infection with a high mortality rate if left untreated. The occurrence of necrotizing infections in the head and neck region is uncommon; therefore, it is a rare cause of chest pain presenting to the emergency department. Here, we present an interesting case of fungal cervical skin abscess complicated by necrotizing fasciitis that progressed to involve the mediastinum, causing necrotizing mediastinitis with pneumomediastinum in an elderly female. The patient presented to the emergency department with chest pain, shortness of breath, and fever. She had a 10-day history of a mass in the anterior midline of her neck with odynophagia. After radiologic confirmation, she was taken to the operating room where she underwent incision and drainage with debridement and washout. Postoperatively, she was given broad-spectrum antibiotics empirically, which were later replaced with intravenous (I/V) fluconazole after culture reports. Prompt diagnosis and treatment lead to the early recovery of the patient and subsequent discharge without any complications. We report this case to draw the attention of emergency medicine physicians and clinicians to this rare and life-threatening but treatable condition. Expeditious diagnosis and treatment lead to early recovery and fewer postoperative complications.
