Rationale: Palatine tonsil is an extremely rare site for metastatic disease, accounting for 0.8% of malignant tonsillar neoplasms. To the best of our knowledge, this is the first report of metastatic adenocarcinoma in the tonsil treated with wide excision and targeted therapy, with no local recurrence 6 months postoperatively. Patient concerns: A 75-year-old man presented hemoptysis and mild productive cough for 2 weeks. Diagnoses: Palatine tonsil metastasis from lung adenocarcinoma, pT2bN0M1b, stage IVA, was confirmed. Interventions: Wide excision of primary lung tumor and metastatic tonsil carcinoma has been performed, and the patient was undergoing targeted therapy with the epidermal growth factor receptor inhibitor afatinib. Outcomes: There was no local recurrence in the oropharynx 6 months postoperatively. Lessons: We aim at highlighting the importance of a thorough evaluation for suspicion of tonsillar enlargement, which might be a sign of a primary malignancy elsewhere.
Effusion-based lymphoma (EBL) is a rare but distinct entity of large B-cell lymphoma in effusion without association with human herpes virus-8 (HHV-8). Spontaneous regression after pleurocentesis has been observed; but to our knowledge, there are no reports on the morphological and molecular features of subsequent aspirations in regressing cases. Here, we report the case of a 92-year-old male with chronic obstructive pulmonary disease, who presented with right pleural effusion. He had no human immunodeficiency virus, hepatitis B virus, or hepatitis C virus infection, and CT scans revealed no mass lesion. The first pleural effusion aspiration cytology revealed large lymphoma cells with vesicular nuclei, irregular nuclear contours, and prominent nucleoli, consistent with EBL. The second aspiration cytology showed a few slightly enlarged lymphocytes in a background of small lymphocytes. Immunohistochemical study on cell block of the second aspiration revealed equal amounts of CD3-positive and CD20-positive cells. All these cells on the section tested negative for HHV-8 through immunohistochemistry and Epstein-Barr virus by in situ hybridization. Our initial impression was EBL in regression. However, flow cytometric immunophenotyping showed monotypic light chain expression of the gated B-cells. B-cell receptor gene rearrangement study showed a clonal result. Furthermore, fluorescence in situ hybridization revealed rearrangement of IGH gene. The diagnosis of the second aspiration was EBL with morphological regression but retained clonal genetic features. The patient passed away one month after diagnosis without chemotherapy. This case illustrated the importance of ancillary studies in confirming the clonal nature of a morphologically regressing EBL.
Endometrial cancer is one of the most frequent gynecological cancers in women. According to a recent national survey, endometrial cancer has increased rapidly in the past 30 years in Taiwan and the incidence of endometrioid adenocarcinoma has increased more and more quickly in younger age. Although total hysterectomy is usually recommended to eradicate the malignant lesion, this procedure may not be suitable for a young nulliparous woman, especially when the endometrial cancer is early stage. We report a case of consecutive successful pregnancies by in vitro fertilization and embryo transfer (IVF-ET) after conservative management of early stage endometrial carcinoma. To our knowledge, this is the first such case ever been reported in Taiwan. We believe this case will be very encouraging to younger women with early stage endometrial cancer.
Lymphangiomas are rare benign tumors of the lymphatic system, most often found at birth and before the age of 2 years. The head and neck region are the most frequent locations for lymphangioma. Involvement of the adult larynx in isolation is rare, and only a few cases have been reported so far. We report the case of a patient with a left false vocal cord reddish tumor presenting with hemoptysis and voice cracking. The surgical excision of mass was performed by direct laryngoscopy-assisted CO2 laser. The histopathological report revealed the diagnosis as cavernous lymphangioma. After a follow-up of 1 year, the patient is free of recurrence with all laryngeal functions being normal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
