Urinary cytology is an uncommon investigative tool for pediatric tumors.
A 16-month-old infant presented for investigation ofhematuria and blood clots into diapers. Urinary cytology showed a population of small, round, blue cells with little cytoplasm and high nuclear/cytoplasmic ratios. The cells were positive for desmin and negative for cytokeratin. A cytologic diagnosis of embryonal rhabdomyosarcoma was offered and subsequently confirmed by histopathology.
Embryonal rhabdomyosarcomas are not uncommon in the pediatric population. Urinary cytology may be useful for rapid diagnosis and early management of such cases.
尿液细胞学检查是儿科肿瘤中一种不常用的检查手段。
一名16个月大的婴儿因血尿和尿布中有血凝块前来检查。尿液细胞学检查显示一群小的、圆形的蓝色细胞，细胞质少，核质比高。这些细胞结蛋白阳性，细胞角蛋白阴性。给出了胚胎性横纹肌肉瘤的细胞学诊断，随后经组织病理学证实。
胚胎性横纹肌肉瘤在儿科人群中并不罕见。尿液细胞学检查可能有助于此类病例的快速诊断和早期处理。
