ABSTRACT
Rippled-pattern sebaceoma, a very rare histologic variant of sebaceoma, manifests as a peculiar arrangement of basaloid cells in linear and parallel rows, resembling Verocay bodies. It represents dermal aggregations composed of small, monomorphous, basaloid, sebaceous germinative cells. It has a tendency to occur in men, with the scalp as the predilection site. To our knowledge, only one case has been reported to date in the Korean dermatologic literature. Here, we report a case of rippled-pattern sebaceoma that appeared as a flesh nodule on the occiput and had been present for 4 years in a 41-year-old man.

Sebaceoma is a benign neoplasm with sebaceous differentiation, and this is characterized by dermal aggregations of basaloid, immature sebaceous cells and sebaceous duct-like structures. Recently, some cases of sebaceoma that presented as a rippled-pattern resembling the palisading of nuclei of verocay bodies have been reported in the English literature. However, there has been no such report in the Korean dermatologic literature. We report here on a case of rippled-pattern sebaceoma that developed in a 78-year-old Korean man.

In the tumor, several histologic variants have been described including a rippled-pattern variant. The unique finding of rippled-pattern trichoblastoma is a peculiar arrangement of the basaloid cells in linear rows parallel to one another, resembling the palisading of nuclei of Verocay bodies. Only a few case reports of rippled-pattern trichoblastoma have been reported in the English literature, but there has been no report in the Korean literature. Herein we report two cases of rippled-pattern trichoblastoma.
