Hybrid cyst is a rare cystic lesion that includes more than two components of the pilosebaceous units. To clarify the clinical and pathological features of hybrid cysts, we report two cases and review 15 cases of hybrid cyst in Japan. On the whole, the age range was 12-73 years with a 2.95:1 female predominance and predilection for the scalp and face (46.7%). Most of the tumours presented as a solitary lesion and the size range was 2-45 mm. The most frequent histological type was the combination of infundibular and trichilemmal cysts (60.0%). Studying the clinicopathological features of hybrid cysts helps us in understanding the pathogenesis of diseases arising from pilosebaceous units.
