Abstract

We report a case of trichogenic tumor with epithelial and mesenchymal components recapitulating the formation of hair germs. The epithelial lobules were highly pigmented and affected the full thickness of the dermis, extending into the subcutaneous fat. In addition, amyloid deposits were found within the epithelial lobules and in the stroma. The overall architecture was reminiscent of hair bulbs. Problems of differential diagnosis with other trichogenic tumors and pigmented tumors are discussed.

摘要

我们报告一例具有上皮和间充质成分的毛发源性肿瘤，其重现了毛胚的形成。上皮小叶色素沉着明显，累及真皮全层，并延伸至皮下脂肪。此外，在上皮小叶内和间质中发现了淀粉样沉积物。整体结构让人联想到毛球。文中讨论了与其他毛发源性肿瘤和色素性肿瘤的鉴别诊断问题。
