皮肤纤维瘤是皮肤内的小而无害的增生，通常直径较小。这些称为结节的增生可以在身体的任何部位出现，但最常见于手臂，小腿和上背部。
皮肤纤维瘤见于成人，在儿童中很少见。它们在女性中比在男性中更常见，并且在免疫系统受损的人群中更常见。
它们的颜色可能不同与肤色，颜色可能会随着时间而变化。
皮肤纤维瘤质韧，许多人说它们感觉像是一块在皮下或凸起于皮面的小石头。大多数皮肤纤维瘤不伴疼痛。

也有一些皮损会出现瘙痒或刺激，以及触痛。

皮肤纤维瘤也可称为良性纤维组织细胞瘤。

那么皮肤纤维瘤是如何发病的？怎么治疗？让我们继续看下去吧～

Dermatofibromas are small, harmless growths within the skin that usually have a small diameter. These growths, called nodules, can grow anywhere on the body, but are most common on the arms, lower legs, and upper back.
Dermatofibromas are seen in adults but are rare in children. They are more frequent in women than in men and are more common in people with compromised immune systems.
They can vary in color, and the color may change over the years.
Dermatofibromas are firm to the touch. They are very dense, and many people say they feel like a small stone underneath or raised above the skin. Most dermatofibromas are painless.
Some people experience itching or irritation at the site of the growth, as well as tenderness.

Dermatofibromas may also be called benign fibrous histiocytomas.

Now let's take a look at this disease in detail.

01

皮肤纤维瘤有什么症状？Symptoms

皮肤纤维瘤往往生长缓慢。这些增长通常具有一些特征。皮肤纤维瘤的关键特征是：
√ 外观 - 主要在皮肤下的圆形凸起。
√ 大小 - 正常范围大约是圆珠笔尖到豌豆的大小，通常不会增大。
√ 颜色 - 可能有不同程度的粉红色，红色，灰色，浅褐色或紫色，并可能随时间而变化。
√ 位置 - 最常见于腿部，但有时位于手臂，躯干，身体其他部位不常见。
√ 其他症状 - 通常无害且无痛，但偶尔可能会发痒，触痛，疼痛或发炎。

当挤压时，皮肤纤维瘤不会向皮肤表面凸出。相反，它会向内凹陷，这可以帮助分辨皮肤纤维瘤和其他皮肤肿物。
通常只会单个出现。然而，多个皮肤纤维瘤更可能发生在免疫系统较弱的人群中。
皮肤肿物可能令人担忧，但皮肤纤维瘤是无害的，不会发展为癌症生长。
Dermatofibromas tend to grow slowly. The growths typically have some defining characteristics that can help identify them. Key markers of a dermatofibroma are:
Appearance - a round bump that is mostly under the skin.
Size - the normal range is about the size of the tip of a ballpoint pen to a pea, and it usually remains stable.
Color - may be pink, red, gray, light brown or purple in varying degrees, and may change over time.
Location - most commonly found on the legs, but sometimes on the arms, trunk, and less common elsewhere on the body.
Additional symptoms - usually harmless and painless, but occasionally may be itchy, tender, painful, or feel inflamed.
When pinched, a dermatofibroma will not push towards the surface of the skin. Instead, it will dimple inward on itself, which can help tell the difference between a dermatofibroma and another type of growth.
It is usual for only one growth to appear on the body. However, multiple dermatofibromas are more likely to occur in people with weakened immune systems.
Skin growths can be alarming, but dermatofibromas are harmless and do not develop into cancerous growths.

皮肤纤维瘤为何会出现？Causes and risk factors

皮肤纤维瘤是深层皮肤中额外细胞的积累。这些增长的确切原因尚不清楚。
它们可能是由于对微小创伤的不良反应引起的，例如虫咬，碎片或针刺导致的创伤。
年龄可能是另一个风险因素，因为增长主要出现在成年人身上。免疫系统受抑制的人可能更有可能经历皮肤纤维瘤，并且可能有不止一次的生长。多发性皮肤纤维瘤在患有系统性红斑狼疮的人中尤为常见。

Dermatofibromas are an accumulation of extra cells within the deeper layers of the skin. The exact cause of these growths is unknown.
They may be caused by an adverse reaction to a small injury, such as a bug bite, splinter, or puncture wound.
Age may be another risk factor, as the growths appear mostly in adults. People with suppressed immune systems may be more likely to experience dermatofibromas, and may have more than one growth. Multiple dermatofibromas are especially common in people with systemic lupus.

皮肤纤维瘤如何治疗？Treatments

大多数皮肤纤维瘤不需要治疗。除了影响外观，它们通常不会引起任何症状。但是，有些人仍然选择手术切除。如果影响外观或长在令人尴尬的地方，移除尤其常见。
通常通过完全切除来移除皮肤纤维瘤。但手术伤口可能留下疤痕。
其他治疗方法包括用液氮冷冻或用糖皮质激素局部注射。这些方法可能有效，但可能仍然只能消除皮肤肿物的上半部分。有时激光也能有效。
Most dermatofibromas do not require treatment. They can be safely left alone and will usually cause no symptoms, aside from their appearance on the skin. However, some people still choose to remove them. Removal is especially common if the growth is unsightly or in an embarrassing place.
Dermatofibromas are usually taken out by removing the growth entirely. This can leave scar after it heals.
Other treatment methods include freezing a growth with liquid nitrogen or injecting it with corticosteroids. These methods can be successful, but may still only eliminate the upper part of the growth. Laser procedures have also been used.
