男性(病案号35108),1959年(31岁时)左颈部淋巴结病理活检为鼻咽癌转移,癌细胞团周围有大量嗜伊红细胞浸润。经两个疗程放疗,情况良好,并参加工作。直至1982年因眩晕,听力减退住院。右外耳道分泌物涂片及肉芽组织切片检查,均为高分化鳞状上皮细胞癌,癌周组织内仍有少量嗜伊红细胞,与59年淋巴结转移癌结构类型相似。经头颅拍片,颅底有骨质破坏,考虑为鼻咽癌所致,再次放疗,于1984年1月因颅内转移病故。本例鼻咽癌转移,经放疗存活24年余。首次颈淋巴结活检见癌细胞团周围有大量嗜伊红细胞围绕,23年后右耳道癌周组织内仍有少数嗜伊红细胞。这和通常所见原发或转移癌以淋巴细胞浆细胞等反应为主不同,虽其机理尚不明了,但亦可能是
Male (Case No. 35108), 1959 (31 years old) left neck lymph node biopsy for the transfer of nasopharyngeal carcinoma, a large number of eosinophil infiltration around the cancer cell mass. After two courses of radiotherapy, it was in good condition and she took part in the work. Until 1982 due to dizziness, hearing loss was hospitalized. The right ear canal secretion smear and granulation tissue biopsy were well-differentiated squamous cell carcinomas, and there was still a small amount of eosinophils in the pericancerous tissue, similar to the 59-year type of lymph node metastasis. After the head shot, there was bone destruction at the base of the skull, which was considered due to nasopharyngeal carcinoma. Radiotherapy was performed again. In January 1984, it was due to intracranial metastases. In this case, the metastasis of nasopharyngeal carcinoma survived more than 24 years after radiotherapy. On the first cervical lymph node biopsy, there were a large number of eosinophils surrounding the cancer cell mass. After 23 years, there were still a few eosinophils in the right otic cancer tissue. This is different from the usual reaction of primary or metastatic cancer with lymphocyte plasma cells. Although the mechanism is still unknown, it may also be
