Abstract：Objective To investigate the characteristics of epidermal cysts in hairless extremities.Methods The clinical data of 3 cases of epidermal cysts were collected,and their clinical and pathological characteristics were analyzed.Results Disease duration ranged from 4 months to 1 year.Patient 1 had a lesion on the palmar side of the second finger of the right hand after a trau-ma.Patients 2 and 3 had lesion on the sole and lateral side of the foot,respectively,with no his-tory of trauma.Histopathological examination showed that the cyst walls were composed of multiple lamellar squamous epithelium and granular layers,and the cyst cavity was filled with keratin,con-sistent with the histopathological changes of typical epidermal cysts.Following surgical removal of the cysts,no recurrence was observed during six-month follow-up.Conclusions The epidermal cysts in hairless parts of the extremities have a short onset time,without opening surface,eruption or secretion.The pathological changes are the same as those in hairy parts of the epidermal cysts.The preferred treatment is complete surgical resection.
