Background: Primary malignant mediastinal germ cell tumors (PMMGCTs) including seminomas and nonseminomatous germ cell tumors (NSGCTs) are rare, and sometimes the diagnosis is very difficult.

Purpose: The purpose of this study is to compare the clinical characteristics, biomarkers, and imaging findings of seminomas and NSGCTs and to determine whether these features could help distinguish these two types of PMMGCT.

Material And Methods: A retrospective study of 24 male patients with histopathologically proven PMMGCT was performed. Read More

Background: Growing teratoma syndrome is a rare phenomenon seen in nonseminomatous germ cell tumors after chemotherapy, where the tumor grows paradoxically despite normalization of tumor markers. It has been found in various locations, most commonly, the retroperitoneum in association with metastatic disease. The occurrence of growing teratoma syndrome in a mediastinal primary is very rare and there are only a few reports in the literature. Read More

We retrospectively evaluated by means of F-FDG PET/CT lymphoid tissue changes in the mediastinal/hilar lymph nodes and the spleen in response to ipilimumab administration in metastatic melanoma.

Methods: A total of 41 patients with unresectable metastatic melanoma underwent F-FDG PET/CT before the start of ipilimumab (baseline PET/CT), after two cycles (interim PET/CT) and at the end of treatment (late PET/CT). Read More

Rationale: Thymic carcinoids are a rare type of malignant neuroendocrine tumors which have a poor prognosis due to their distant metastasis, invasive behaviour, and postoperative recurrence. Surgical resection is still the fundamental mode for treating thymic carcinoids. Here, we report the rapid shrinkage of an atypical thymic carcinoid with multiple metastases following chemoradiation plus octreotide as a first-line therapy PATIENT CONCERNS:: A 39-year-old Chinese man presented with chest tightness, dyspnea with a history of lumbago and untreated malignant thymoma.

Anterior mediastinal masses present a significant challenge in the perioperative period. Standard anaesthetic induction and airway management are often not feasible due to the risk of complete respiratory and/or cardiovascular collapse. Invasive manoeuvres, such as extracorporeal membrane oxygenation, cardiac bypass, or tracheal or bronchial stenting, are sometimes not applicable due to significant anatomic aberration. Read More

Introduction: Paragangliomas (PGs) or extra-adrenal pheochromocytomas are rare neuroendocrine neoplasms of ubiquitous distribution. Those that produce excess catecholamine are categorized as functional, and those that do not are categorized as nonfunctional. Although modern medical technology is becoming more widespread, there are still substantial risks of misdiagnosis or missed diagnosis of PGs. Read More

Teratomas can be found in different organs of the body and may involve gonads, saccrococcygeal region, mediastinum and other sites. Intrathoracic teratomas always occur in mediastinum and less often arise within the lung. As teratomas mostly involve sex organs (gonads), they rarely occur as extra-gonadal tumors accounting for only 3% of all the cases and very small percentage of such tumors occur in mediastinum.
