The mediastinum is a complex anatomic region that can pose many diagnostic challenges on fine-needle aspiration (FNA) and core needle biopsy (CNB). With the recent technological advancements in EBUS-TBNA and EUS-guided procedures, FNA/CNB is being increasingly utilized to obtain the initial and, in many cases, the only diagnosis. As a result, it is imperative to have an understanding of the pearls and pitfalls associated with both the more common and rarer malignancies that occur at this site. Read More

Neurogenic tumors represent a broad ill-defined category of neoplasms that includes tumors of Schwann cell and/or neuroblastic derivation, as well as neoplasms that typically develop in the central nervous system, but rarely present in ectopic sites including the mediastinum. Neurogenic tumors may occur at many different anatomic sites, but the mediastinum represents a uniquely challenging site given the complex anatomy. Additionally, some of these neoplasms may present with multicentric involvement in the context of genetic syndromes, including NF1, NF2 and schwanomatosis. Read More

Ganglioneuromas are rare benign tumors that arise from the sympathetic nerve fibers and represent the final maturation stage of neuroblast tumors. The most common sites of involvement in the body include posterior mediastinum, followed by retroperitoneum, adrenal gland, and soft tissues of the head and neck. In the mediastinum, this tumor is most frequently located in posterior compartment, together with other neurogenic tumors. Read More

A hibernoma is an uncommon benign soft tissue tumor composed of brown adipose cells; the mediastinal location as presentation is scarce, with only six cases previously reported. The diagnosis of hibernoma is challenging and must be made based on the clinical, radiographic, and cytologic features. Here we present a 33-year-old woman without any relevant medical history presented for outpatient evaluation of a dry cough persisting for three months, and the X-rays revealed a dense well-defined mass with smooth borders in the left upper posterior mediastinum.

Introduction: Mediastinal lesions are uncommon; studies on their distribution are, in general, small and from a single institution. Furthermore, these studies are usually based on pathology or surgical databases and, therefore, miss many lesions that did not undergo biopsy or resection. Our aim was to identify the distribution of lesions in the mediastinum in a large international, multi-institutional cohort. Read More

Background: The authors presented a 63-year old female synchronously complicated with a thymic tumor located at the left-side of the superior mediastinum, and a paravertebral tumor located at the right-side of the lower thorax. Conventional thoracoscopic surgical procedure using rigid instruments to simultaneously resect the two tumors via the same ports might be technically challenging. To our knowledge, the use of a surgical robot allowed the surgeon to perform precise dissection from extreme angles with the characteristic of articulating surgical instruments. Read More

Background: Germ cell tumors (GCTs) in children are rare neoplasms with diverse pathological findings according to the site and age of presentation. The most common symptoms in children with mediastinal GCTs, which are nonspecific, are dyspnea, chest pain, cough, hemoptysis, vena cava occlusion syndrome, and fatigue/weakness. Because of these nonspecific symptoms, it is difficult to suspect a mediastinal mass. Read More

The objective of this study was to identify the differences in histopathological distribution and clinical features of mediastinal lesions (MLs) across the age spectrum in Chinese series of patients and to compare with the available literature. A total of 409 cases of MLs, including 137 pediatric and 272 adult patients from a single institution, was reviewed and categorized into groups according to age. Among the 409 cases, the age showed a bimodal distribution with an increased incidence of MLs among (< 10 year) and (60-< 70 year) age groups. Read More

Solitary paravertebral schwannomas in the thoracic spine and lacking an intraspinal component are uncommon. These benign nerve sheath tumors are typically treated using complete resection with an excellent outcome. Resection of these tumors is achieved by an anterior approach via open thoracotomy or minimally invasive thoracoscopy, by a posterior approach via laminectomy, or by a combination of both approaches.

Reactive and neoplastic thymic pathologies are the main considerations in the case of masses in the anterior and middle part of the mediastinum, while neurogenic tumors are predominant in the posterior mediastinum (which are not dealt with here). In neonates and infants, the commonest pathologies in the anterior mediastinum comprise germ cell tumors (mainly teratomas), congenital thymic cysts and true thymic hyperplasia (TTH). In toddlers, teratomas, yolk sac tumors and cysts predominate. Read More

Intrathoracic schwannomas are neurogenic tumors derived from the Schwann cells of the nerve sheath, most often seen in the posterior mediastinum with anatomical correlations to nerves. Although they are typically benign, a malignant transformation can occur, and thoracotomy instead of video-assisted thoracoscopic surgery (VATS) is required to achieve a complete resection.
