A 73-year-old Hispanic woman presented to the clinic with an erythematous, friable 3.0 cm × 2.7 cm × 0.7 cm mass located on the posterior vertex of the scalp (Figure 1). The lesion had been present since birth but had recently begun to bleed intermittently, prompting evaluation. A biopsy was obtained, revealing a tumor with irregular, complex papillomatous invaginations lined by a two-layered epithelium. Atypical and crowded columnar cells lined the luminal aspect, while cuboidal cells lined the epithelium adjacent to the stroma (Figure 2). Decapitation secretion was noted in several areas on the luminal surface.
一名73岁的西班牙裔女性因头皮后顶有一个3.0厘米×2.7厘米×0.7厘米的红色、易碎肿物就诊于诊所（图1）。该病变自出生就存在，但最近开始间歇性出血，促使其前来评估。进行了活检，结果显示肿瘤具有不规则、复杂的乳头状内陷，内衬两层上皮。管腔面由非典型且密集的柱状细胞排列，而靠近间质的上皮则由立方细胞排列（图2）。在管腔表面的几个区域发现了断头分泌现象。
