Description
Summary:The following is a case study of a 36‐year‐old Japanese man with a trichoblastoma which exhibited a rippled‐pattern on the left temporal region of the scalp. The histological findings of the tumor revealed lobular aggregations composed of immature follicular basaloid cells, lobules of squamous eddy‐like foci of incomplete keratinization or small keratinous cysts, and multiple papillary mesenchymal bodies similar to hair germ. Interestingly, a rippled‐pattern of basaloid cells and hyalinized matrixes resembling the Verocay bodies of neurilemmoma was also observed. We propose that the rippled‐pattern of the basaloid cells and hyalinized matrices is caused by the characteristic stromal induction of trichoblastoma.
