Mediastinal Paraganglioma

A 54-year-old man was referred to our institution with hemoptysis and hoarseness of 1 year's duration. A computed tomography (CT) scan showed an anterior mediastinal mass (2.5 cm x 1.0 cm), which was diagnosed as thymoma. The tumor was resected under a sternotomy. The tumor had invaded the anterior wall of the ascending aorta. With the patient under cardiopulmonary bypass, the aortic wall invaded by the mass was resected, and arterial reconstruction was performed with patch material. The tumor was revealed to be a tumor of neuronal origin. The patient's postoperative course was uneventful. The patient was discharged on postoperative day 9. One year after the operation, a follow-up chest CT evaluation showed no specific complications or recurrence.

Experienced Pain

We report about a 14-year-old boy who presented with an anterior mediastinal mass that was diagnosed as malignant teratoma. Surgical resection was performed along with pre- and postoperative chemotherapy. Although elevated alpha-fetoprotein became negative, he experienced pain in his right hip joint 3 months after resection. Systematic evaluation revealed multiple locations of metastasis, and the pathological diagnosis based on bone biopsy was malignant melanoma originating from malignant teratoma, which rapidly progressed. He died 15 months after diagnosis of the original malignant teratoma. Diagnosing and treating malignant transformation of teratoma, including malignant melanoma, is difficult because it is very rare. To our knowledge, this is the second reported case of malignant melanoma arising from a mediastinum malignant teratoma, with both cases having a poor prognosis. In addition to the follow-up of tumor markers, systematic evaluation, including imaging, should be considered even after remission to monitor malignant transformation of teratoma. We expect to establish a successful therapy and improve mortality rate after more such cases are accumulated.

Abstract Casestudy A 52-year-old female presented with night sweats, chills, anorexia, and weight loss. Computed tomography and positron emission tomography showed a soft tissue infiltration in the anterior mediastinum and hypermetabolic bilateral supraclavicular, mediastinal, right hilar, and left internal mammary lymph nodes. An anterior mediastinal mass resection and thymectomy was subsequently performed. Results Sections of the mediastinal mass showed Hodgkin/Reed-Sternberg cells (HRS) admixed with small lymphocytes, histiocytes, plasma cells, and eosinophils. The HRS cells are positive for CD30, CD15, and MUM1, faintly positive for PAX5, and negative for CD20, CD45, CD79a, and BCL6. The morphology and immunophenotype is diagnostic of nodular sclerosis classic Hodgkin lymphoma (CHL). Sections of the thymectomy specimen showed similar morphology, however, in an area that represents 10-20% of the specimen, there are nodular and diffuse lymphoid infiltrates consisting of small lymphocytes, histiocytes, and large atypical cells. The large atypical cells are positive for CD20, CD23, CD30, CD45, CD79a, BCL2, BCL6, MUM-1, and PAX5, and negative for CD1a, CD3, CD57, and Cyclin D1. The background small CD3-positive lymphocytes form a rosette around most of the large atypical cells. CD21 and CD23 stains highlight residual follicular structures. In situ hybridization for EBV-encoded RNA (EBER) is negative. The presence of residual follicular meshwork with an immunophenotype of large B cell lymphoma supports a diagnosis of a gray zone lymphoma (GZL). Overall, CHL is involving 80-90% and GZL is involving 10-20% of the thymic tissue. The patient was subsequently placed on ABVD chemotherapy and achieved remission. Conclusion An accurate diagnosis of GZL is challenging. GZL is a rare type of lymphoma with morphological features between CHL and diffuse large B-cell lymphoma (DLBCL). It is even rarer to encounter a CHL concurrently present with a GZL. The optimal therapeutic approach for cases with concurrent lymphoma diagnosed with CHL and GZL needs further investigation.
