Yun HK, Yun SI, Lee YH, Kang KM, Kwak EK, Kim JS, Cho SR, Kwon JB - J. Korean Med. Sci. (2010)

Bottom Line: On microscopy, syncytial growth pattern and indistinct cytoplasmic borders were observed with the severe infiltration of lymphoid cells.The case was followed-up for 8 months without recurrence.This is the first report of a LELCA case in Korea.

ABSTRACT
A 78-yr-old woman presented with gross hematuria for 2 weeks. On cystoscopy, a frond-like mass was observed at the bladder trigone. Transurethral resection of bladder tumor was performed for the mass. Histopathological findings showed that 90% of lesions were lymphoepithelioma-like carcinoma (LELCA) and a few lesions were non-invasive transitional cell carcinoma. On microscopy, syncytial growth pattern and indistinct cytoplasmic borders were observed with the severe infiltration of lymphoid cells. The case was followed-up for 8 months without recurrence. This is the first report of a LELCA case in Korea.

Mentions: On microscopy, syncytial growth pattern and indistinct cytoplasmic borders were observed with the severe infiltration of lymphoid cells. The findings of necrosis and mitosis were observed in many regions. It was found that tumor cells invaded the whole lamina propria. Non-invasive transitional cell carcinoma was concomitant fractionally (Fig. 2).
