Lipedematous lesions of the scalp share a wide range of morphologic criteria with classical lipomatosis. In the past decade, lipedematous scalp and lipedematous alopecia have been described as pathomorphologically related diseases of the scalp, but many clinicians and dermatopathologists disagree with this assessment. Morphologic and pathogenetic concepts remain unclear and raise the concern that a plethora of terms are being used to describe and distinguish phenotypical variations of an identical theme.
Here, we report a 15-year-old male Turkish child with what we could consider, according to the currently accepted classifications, lipedematous scalp without associated alopecia.
The principal aim of this manuscript is to critically reappraise the current literature on lipomatous lesions and focus on morphologic features in order to reestablish five crucial diagnostic criteria.
Due to the possibility of excluding therapeutic elements by separating the lipomatous lesions into various entities, we propose using the term "localized lipomatosis of the scalp with or without associated alopecia" in order to arrive at a straightforward diagnosis, thereby avoiding numerous partially synonymous terms; moreover, we do not intend to expand the spectrum of distinct lipomatous entities, but propose classification of these diseases within the group of conventional lipomatosis.
头皮脂肪性病变与经典脂肪瘤在形态学标准上有广泛的重叠。在过去的十年中，脂肪性头皮和脂肪性脱发已被描述为头皮的病理相关疾病，但许多临床医生和皮肤病理学家不同意这种评估。形态学和发病机制的概念仍不清楚，并引起了人们的关注，即过多的术语被用于描述和区分同一主题的表型变异。
在这里，我们报告了一名 15 岁的土耳其男性儿童，根据目前公认的分类，我们可以将其视为无相关脱发的脂肪性头皮。
本文的主要目的是批判性地重新评估目前关于脂肪性病变的文献，并关注形态学特征，以便重新建立五个关键的诊断标准。
由于通过将脂肪性病变分为不同的实体，可以排除治疗因素，因此我们建议使用“伴有或不伴有相关脱发的头皮局限性脂肪增多症”这一术语，以便进行直接诊断，从而避免使用许多部分同义的术语；此外，我们并不打算扩大不同脂肪性实体的范围，而是建议将这些疾病归类为传统脂肪瘤的范畴。
