Nevus sebaceus or sebaceous nevus (also known as an "organoid nevus") is a congenital, hairless plaque that typically occurs on the face or scalp. Such nevi are classified as epidermal nevi and can be present at birth, or early childhood, and affect males and females of all races equally.
Nevus sebaceus 是一種先天性皮膚缺陷,毛囊與皮脂腺異常增生。這些增生常見於頭皮,也可能出現在前額、臉部或頸部。因荷爾蒙變化,於青春期時其生長速度往往加快。成年後,這些病灶可能會發展成額外的腫瘤 (trichoblastoma)。對於這些病灶的治療仍具爭議,處理方式可從僅觀察到在兒童期早期切除不等。 Nevus sebaceus of Jadassohn also referred to as organoid nevus, is a congenital malformation involving hamartomas of the pilosebaceous follicular unit. These growths most commonly form on the scalp, but may also appear on the forehead, face, or neck. They undergo a growth phase during puberty due to hormonal changes. In adulthood, the growths may develop secondary neoplasms within them, most commonly trichoblastoma. The treatment of these lesions is controversial, with options ranging from observation to early excision in childhood.
Congenital melanocytic nevus 是一種在出生時或嬰兒期形成的胎記。Nevus sebaceous 是一種涉及毛囊缺陷的皮膚異常。在這項研究中,我們使用稱為針孔法的雷射技術和 Erbium: YAG 雷射,治療不同患者的痣病變。 Congenital melanocytic nevus (CMN) is a melanocytic nevus that is either present at birth or appears during the latter stages of infancy. Nevus sebaceous has been described as the hamartomatous locus of an embryologically defective pilosebaceous unit. Here, we describe how we used the pinhole technique with an erbium-doped yttrium aluminium garnet (erbium : YAG) laser to treat nevi lesions in different patients.
基底細胞癌可能發生於皮脂腺痣,多於成年期出現。然而,目前已知此類惡性腫瘤的發生率低於預期,因此不再建議預防性切除。
