Etiologies of Pseudo-horn cyst (Epidermoid cyst) of the dermis
- Pseudo-horn cysts are benign developmental anomalies that occur as a result of the sequestration of the skin along the lines of embryonic closure 1
- They can also be found in areas of the body that have had solar exposure, with a wide variety of histopathological findings at the base of these lesions, ranging from benign to premalignant to malignant 2
- Seborrheic inclusion cysts, a variant of epidermal cyst, can also contain pseudo-horn cysts, and are characterized by seborrheic keratosis-like lesions in epidermal cysts 3, 4
Treatment options for Pseudo-horn cyst (Epidermoid cyst) of the dermis
- Complete surgical excision of the cyst wall is the treatment of choice for postauricular dermoid cysts, as incomplete removal may result in recurrence or infection 1
- Cutaneous horns, which can be associated with pseudo-horn cysts, should be completely excised and sent for pathological evaluation to rule out malignant changes 2
- Seborrheic inclusion cysts, which can contain pseudo-horn cysts, can be treated with conservative treatment, such as enbloc resection, and histological examination can confirm the diagnosis 4
- The prognosis is excellent without further complication if the cyst is completely excised 1
