鼻腭囊肿的色素沉着极其少见,仅见3例报道。作者现报告2例。两名患者为日本妇女,年龄分别为63岁和27岁。活检发现鼻腭囊肿上皮内有色素沉着。标本用10%福尔马林液固定,石蜡包埋。HE 染色,并做特殊染色,鉴定色素的组织化学性质。结果两例囊壁均由致密胶原纤维和血管神经组成,均由复层鳞状上皮和假复层纤毛柱状上皮衬里。上皮衬里的基底细胞间散在分布少数卵圆形细胞。用 HE染色看到上皮细胞内散在有褐色色素沉着。例1切片
The pigmentation of nasal cysts is extremely rare and only three cases have been reported. The author now reports 2 cases. Two patients were Japanese women, aged 63 and 27, respectively. Biopsy revealed hyperpigmentation in epithelial cysts. Specimens were fixed in 10% formalin and embedded in paraffin. HE stained and stained specifically to identify the histochemical properties of the pigment. Results The cystic wall of both cases consisted of dense collagen fibers and vascular nerves, which were lined by stratified squamous epithelium and pseudo-columnar columnar epithelium. A small number of oval cells are scattered among the basal cells of the epithelial lining. HE pigmentation was observed in the epithelial cells scattered brown pigmentation. Example 1 slice
