Lymph node metastasis as the initial symptom of a germ cell tumor in an adult: A case report.

RATIONALE: Germ cell tumors in the head and neck are very rare. In cases of germ cell tumors, it is uncommon for lymph node metastasis to be the only and initial symptom, and this can easily lead to a misdiagnosis. Herein, we report about a 28-year-old woman with lymph node metastasis, in whom a primary tumor appeared in the nasal cavity. PATIENT CONCERNS: A 28-year-old woman presented with enlarged left submandibular lymph nodes. No other mass was found on whole-body screening using positron emission tomography-computed tomography. DIAGNOSIS: After partial submandibular lymphadenectomy was performed, histopathological and immunohistochemical examinations revealed a metastatic germ cell tumor. However, it was difficult to further classify and affirm the origin. INTERVENTIONS: As the patient was receiving four cycles of bleomycin, etoposide, and cisplatin chemotherapy, a primary tumor emerged in the nasal cavity, which was finally confirmed as an immature teratoma of a high World Health Organization histological grade and Norris grade 3. This tumor was found to contain similar components to lymph nodes with respect to histopathological and immunohistochemical characteristics, especially the immature neural tubes or nervous tissue in the nasal cavity. Fortunately, the patient recovered well with no signs of relapse, and the size of residual lymph nodes remained unchanged after she received another four cycles of bleomycin, etoposide, and cisplatin chemotherapy and two cycles of doxorubicin and ifosfamide (AI) chemotherapy. OUTCOMES: Unfortunately, 11 months later, during the coronavirus disease pandemic, the patient died owing to respiratory failure and pulmonary infection. CONCLUSIONS: In cases of malignant tumor in the submandibular lymph nodes of adults, the metastasis of a germ cell tumor should be considered an important differential diagnosis even if a primary tumor does not emerge. In this case, adequate postoperative chemotherapy is necessary.

Case Report: SARS-CoV-2 Infection in a Child With Suprasellar Tumor and Hypothalamic-Pituitary Failure.

In early 2020, a novel coronavirus leading to potentially death was discovered. Since then, the 2019 coronavirus disease (COVID-19) has spread to become a worldwide pandemic. Beyond the risks strictly related to the infection, concerns have been expressed for the endocrinological impact that COVID-19 may have, especially in vulnerable individuals with pre-existing endocrinological health conditions. To date new information is emerging regarding severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) in children but the literature is still scarce concerning this infection in patients with intracranial malignant neoplasms. We report a 9-year-old child infected with SARS-CoV-2 and recent diagnosis of suprasellar non-germinomatous germ cell tumor also suffering from diabetes insipidus and hypothalamic-pituitary failure (hypothyroidism, adrenal insufficiency, hypothalamic obesity and growth hormone deficiency) and its clinical course. The patient remained asymptomatic for the duration of the infection without requiring any change in the replacement therapeutic dosages taken before the infection. We then discuss the proposed approach to treat a pediatric patient with SARS-CoV-2 infection and hypothalamic-pituitary failure and we include a review of the literature. Our report suggests that SARS-CoV-2 infection is usually mild and self-limiting in children even those immunocompromised and with multiple endocrinological deficits. Patients are advised to keep any scheduled appointments unless informed otherwise.

Management of Germ Cell Tumors During the Outbreak of the Novel Coronavirus Disease-19 Pandemic: A Survey of International Expertise Centers.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has become a public health emergency affecting frail populations, including patients with cancer. This poses the question of whether cancer treatments can be postponed or modified without compromising their efficacy, especially for highly curable cancers such as germ cell tumors (GCTs). MATERIALS AND METHODS: To depict the state-of-the-art management of GCTs during the COVID-19 pandemic, a survey including 26 questions was circulated by e-mail among the physicians belonging to three cooperative groups: (a) Italian Germ Cell Cancer Group; (b) European Reference Network-Rare Adult Solid Cancers, Domain G3 (rare male genitourinary cancers); and (c) Genitourinary Medical Oncologists of Canada. Percentages of agreement between Italian respondents (I) versus Canadian respondents (C), I versus European respondents (E), and E versus C were compared by using Fisher's exact tests for dichotomous answers and chi square test for trends for the questions with three or more options. RESULTS: Fifty-three GCT experts responded to the survey: 20 Italian, 6 in other European countries, and 27 from Canada. Telemedicine was broadly used; there was high consensus to interrupt chemotherapy in COVID-19-positive patients (I = 75%, C = 55%, and E = 83.3%) and for use of granulocyte colony-stimulating factor primary prophylaxis for neutropenia (I = 65%, C = 62.9%, and E = 50%). The main differences emerged regarding the management of stage I and stage IIA disease, likely because of cultural and geographical differences. CONCLUSION: Our study highlights the common efforts of GCT experts in Europe and Canada to maintain high standards of treatment for patients with GCT with few changes in their management during the COVID-19 pandemic. IMPLICATIONS FOR PRACTICE: Despite the chaos, disruptions, and fears fomented by the COVID-19 illness, oncology care teams in Italy, other European countries, and Canada are delivering the enormous promise of curative management strategies for patients with testicular cancer and other germ cell tumors. At the same time, these teams are applying safe and innovative solutions and sharing best practices to minimize frequency and intensity of patient contacts with thinly stretched health care capacity.
