1 INTRODUCTION A dermoid sinus is a hereditary congenital malformation that occurs when the ectoderm fails to separate from the neural tube during early embryogenesis. This leads to the formation of a tubular structure lined with adnexal tissue, including hair follicles, sebaceous tissue and sweat glands that usually extend from dorsal midline to various depths of tissues (Kopke et al., 2019; Kiviranta et al., 2011). There have been six types of dermoid sinuses described (Figure 1A–G).
