Abstract
Epidermal cysts are the most common scalp cysts in clinical practice. They are most commonly located in the region of the face, neck, and trunk, and have been reported in many other topographic areas of the body. Clinically, they are present as free-moving nodules located below the skin, ranging in size from a few millimeters to a few centimeters in diameter. Histopathologically, they are defined as benign tumor formations with a very low risk of malignancy. The differential diagnosis includes: lipoma, neurofibroma, salivary gland adenoma, vascular lesion and fibroid, and Trichilemmal cyst. The most common treatment for epidermal cysts is surgical excision with removal of all contents without compromising the integrity of the capsule. In this publication, we present five clinical cases of patients with epidermal cysts in different topographic regions of the body. The patients were treated surgically by elliptical excision and complete removal of epidermal cysts without rupture. The defects were closed with single discontinued skin sutures and the sutures were removed on an 8- / 14-postoperative day. No recurrence was observed in the postoperative period.
Highlights
Epidermal cysts, known as epidermoid, infundibular and keratin, are the most common skin cysts [1]
We present five clinical cases of patients with epidermal cysts in different topographic regions of the body - in the back area, in the head area(regio occipitalis), in the ear area and in the area of the inguinal canal
Acquired cysts are located mainly in the head and neck [4]. They are defined as benign formations with a very low risk of malignancy, as a study by Bauer et al shows that 2.2% of them can develop into well-differentiated squamous cell carcinoma [4,5]
