Epidermoid cysts are divided into two types: congenital and acquired.[sup.5] Although there are many theories about histogenesis, such as teratoma and metaplasia, the most likely explanation of epidermoid cysts throughout the body is an early intrauterine abnormal closure of neural groove or epithelial fusion lines.[sup.1,2,6] It has been reported in any place from the cranium to the anus in midline.[sup.2,4] Epidermoid cyst is one of the benign lesions in the scrotum, and most published cases are located within the testes; this makes it a challenge to the patient and surgeon in terms of preserving the organ.
The caudal neural plate was fairly plentiful (Figure 1d), but the middle neural groove showed weak expression (Figure 1b).
The neural plate border is distinct at E4-E4.5, when the dorsal ectoderm has thickened along the anteroposterior axis of the embryo and a shallow neural groove appears in the midline.
