Skin
- Subcutaneous Mass
Cyst of eyelid typically present during adolescence and late adulthood, as a solitary, elevated, round, freely mobile subcutaneous mass with smooth overlying skin [ 3 ]. Epidermal cyst is common in cases of men. [omicsonline.org]
Treatment
Treatment may be required if the cyst becomes red, swollen, painful, changes in size or character, or is infected. In such cases, treatment options include antibiotics and drainage. Sometimes the cyst may need to be surgically removed. [healthline.com]
Treatment [ edit ] Cysts can be removed by excision. [5] In case of fronto-ethmoidal epidermoid cysts, surgical resection appears to be the mainstay of treatment; however, the extent of resection is dictated by adherence of the tumor capsule to the surrounding [en.wikipedia.org]
The current report should not be taken as an argument against cyst removal, which is the established way of treatment. [ncbi.nlm.nih.gov]
Skin cysts don’t need treatment most of the time. They’re usually painless and nothing to worry about, unless they get sore or infected. But if you have a cyst that bothers you or is embarrassing, you should discuss it with your doctor. [webmd.com]

In practice, both primary and secondary cysts are often described simply as "splenic cyst" for the sake of simplicity, as often the specific etiology is not evident. [radiopaedia.org]
There is no proven etiology, although patients with cysts along the free edge of the fold often are vocally hyperactive. Treatment of cysts, except for those arising on the free edge of the vocal fold, is simple unroofing (marsupialization). [bumc.bu.edu]

Epidemiology
Introduction A painless, benign, slow-growing soft tissue tumor that often occurs in the hand occurs months to years after a traumatic event Epidemiology incidence third most common hand tumor demographics more common in men than women occurs in the third [orthobullets.com]
Epidemiology Benign ovarian tumours occur in 30% of females with regular menses (eg, luteal cysts as incidental findings on pelvic scans) and 50% of females with irregular menses. [patient.info]
Chronic irritation or repetitive trauma to the epithelial lining of the cyst has been suggested to play a role in malignant transformation; however, this relationship has not been established. [44] Epidemiology Race No racial predilection has been identified [emedicine.medscape.com]
Pathophysiology
However, considering that the pathogenesis and pathophysiology of these cysts are unclear, VP shunting should be considered especially for recurrent cases accompanied by hydrocephalus. [ncbi.nlm.nih.gov]

Although developmental and traumatic etiologies have been postulated, the exact pathophysiology of corneoscleral cysts remains unclear [ 1, 2 ]. [em-consulte.com]
Epidermoid cysts are benign lesions; however, very rare cases of various associated malignancies have been reported. [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] Pathophysiology Epidermoid cysts result from the proliferation of epidermal cells within a circumscribed [emedicine.medscape.com]
Prevention
To prevent spontaneous rupture, laparotomy was performed, and the cyst was pathologically diagnosed as a splenic epithelial cyst. [ncbi.nlm.nih.gov]
To prevent recurrence, the entire cyst and its wall should be removed. Ruptured cysts can be incised and drained but may recur if the wall is not eventually removed. Antibiotics are not needed unless cellulitis is present. [merckmanuals.com]
