Epidermal cyst - 表皮囊腫https://en.wikipedia.org/wiki/Epidermoid_cyst
表皮囊腫 (Epidermal cyst) 是皮膚上最常見的良性囊腫。 表皮囊腫 (epidermal cyst) 可能沒有任何症狀,或觸摸時可能會疼痛。它可以釋放浸漬的角蛋白。

表皮囊腫 (epidermal cyst) 約佔所有切除囊腫的85-95%,惡性化極為罕見。囊腫可以透過切除術去除。

治療
手術切除-即使你不斷擠壓從內部流出的東西,它通常也會復發。因此,可能需要手術切除。疼痛性病變及疑似感染應使用抗生素治療。

治療 - 非處方藥
頻繁觸摸受影響的區域可能會導致發炎。大多數大於 1 公分的發炎病灶通常需要在醫院進行手術治療。如果小病變發炎,可以嘗試使用非處方抗生素。不要使用類固醇軟膏治療表皮囊腫​​。

  • 如果通常持續存在的小腫塊突然發炎,則可能懷疑為表皮囊腫。
  • 這種情況很難與普通膿腫區分開來。
  • 表皮囊腫的一個特徵是存在中央排出孔,例如中間有一個黑點。
  • 典型inflammed epidermal cyst ― 中心有一個黑色開口
  • 它看起來像一個緩慢生長的老腫塊,擠壓時,角蛋白物質可能會釋放出來。
  • 表皮囊腫 (Epidermal cyst) 是一個充滿角蛋白的腫塊。
  • 小病灶可能看起來像膿腫,但與膿腫不同的是,表皮囊腫 (Epidermal cyst)經常有可觸及的腫塊。
  • Inflamed thyroglossal cyst

為了改善去除表皮囊腫後的外觀,我們建議採用侵入性較小的方法。我們引入了一種新方法,可以透過二氧化碳雷射打出的小孔完全消除囊腫。我們治療了25名直徑為 0. 5 to 1. 5 公分的囊腫患者,這些囊腫沒有發炎,可以自由活動。所有患者都對術後皮膚的外觀感到滿意。這種技術很簡單,幾乎不會留下疤痕,囊腫順利復發的可能性很小。
To improve the cosmetic results of removing epidermal cysts, minimally invasive methods have been proposed. We proposed a new minimally invasive method that completely removes a cyst through a small hole made by a CO2 laser. Twenty-five patients with epidermal cysts, which were 0.5 to 1.5 cm in diameter, non-inflamed, and freely movable, were treated. All of the patients were satisfied with the cosmetic results. This method is simple and results in minimal scarring and low recurrence rates without complications.

Epidermal inclusion cysts 是最常見的皮膚囊腫類型,可以發生在身體的任何部位。它們通常表現為皮膚表面下的軟腫塊,通常具有可見的中心。這些囊腫會讓患者感到疼痛,感覺就像皮下充滿液體的軟腫塊。
Epidermal inclusion cysts are the most common cutaneous cysts and can occur anywhere on the body. These cysts typically present as fluctuant nodules under the surface of the skin, often with visible central puncta. These cysts often become painful to the patient and may present as a fluctuant filled nodule below the patient's skin.
