Adult Lymphangioma of the Oropharynx: A Case Report.

Lymphangioma insults in adults are uncommon and the occurrence in the oropharynx is extremely rare. Although disease history and clinical symptoms may help in distinguishing it from malignant tumors, the pathophysiology of lymphangioma via histological examinations should be established for convenient and precise diagnosis. We present a 20-year-old male with lymphangioma in the right oropharynx, and the multiple-angle examination and treatment plan used. The case further emphasizes the need to consider lymphangioma in the differential diagnosis of an oropharyngeal mass. Awareness that lymphangioma can occur in adults is important for its proper management, which includes complete surgical removal to prevent recurrence.

Clinical Features of Head and Neck Solitary Extramedullary Plasmacytoma in Taiwan.

BACKGROUND/AIM: Solitary extramedullary plasmacytoma (SEP) is a rare, malignant plasma-cell tumor, which mainly occurs in the head and neck regions. Globally the disease has been rarely happening up to 2019, with only about ten papers focused on SEP cases reported in English. Thus, a literature collectively reviewing the characteristics of the patients would be valuable. PATIENTS AND METHODS: We enrolled 10 SEP patients, and recorded their primary sites and the treatment modality, and analyzed their survival rates and outcomes. We also reviewed previous studies and compared their findings with ours. RESULTS: No gender or age disparity has been observed, and younger patients had a better local control with RT compared to surgery among our patients. CONCLUSION: Further investigations with more patients and long-time follow-up may provide more information for treatment determination and the recurrence and progression from SEP to MM.
