Key Difference – Nodule vs Cyst
结节和囊肿之间的关键区别在于nodules contain solid materials while the cysts contain fluid. Skinlesionsare a common manifestation of many benign and sinister pathological processes taking place inside the human body. Nodules and cysts are two such skin lesions that appear in different disease conditions. Although commonly arising on the skin, it is also possible for these lesions to occur within the internal organs of the body. A nodule is a solid mass in the skin, usually greater than 0.5cm in diameter, both width and depth, and it can appear as elevated from the skin or palpated. Whereas, cysts are nodular lesions containing fluid.

什么是结节?
A nodule is a solid mass in the skin, usually greater than 0.5cm in diameter, both width and depth which can appear as elevated from the skin or palpated.
Conditions that can give rise to nodular skin lesions include,
- Repair mechanisms that are involved in the heal of injuries to body organs can give rise to nodular lesions such askeloid scars.
- Nodules can develop even within the internal body organs. In inflammatory conditions such asrheumatoid arthritis, patients can get pulmonary nodules. Granulomas occurring in certain diseases such as TB are also a type of nodules.
- 恶性肿瘤也会引起结节。
- Thyroid nodules are one of the commonest variety of nodular lesions and are due to a spectrum of pathological conditions including iodine deficiency and thyroiditis.
是什么a Cyst?
Cysts are nodular lesions containing fluid. Different types of cysts commonly encountered during clinical practice are,
- Sebaceous cysts – these have a bluish discoloration on the overlying skin along with a punctum. Surgical excision of them is necessary in order to prevent them from getting an infection.
- Dermoid cysts
- 甲状腺,卵巢和肾脏等内器官中的囊肿
- Painful Bartholin cysts in Bartholin glands of females
What are the Similarities Between Nodule and Cyst?
- Nodule and cyst are more than 0.5cm in diameter.
- Moreover, both have margins that are elevated from the skin level and are palpable.
是什么the Difference Between Nodule and Cyst?
Nodules are solid masses in the skin that can appear to be elevated from the skin or palpated whereas cysts are nodular lesions containing fluid. Therefore, the key difference between nodule and cyst is that the nodules contain solid materials while the cysts contain fluids.
The table below further summarizes this difference between nodule and cyst.
概括– Nodule vs Cyst
结节是皮肤中的固体质量,通常大于直径0.5厘米,宽度和深度。它似乎可以从皮肤上抬高或触诊。囊肿也是含有液体的结节性病变。因此,结节和囊肿之间的主要区别在于结节中充满了固体材料,而液体充满了液体。
