Dermoid cysts are histologically defined as surface epithelium encapsulating an inner lumen. They are well described in the literature as discrete, single masses, either circumscribed or dumbbell-shaped, with or without a longstanding fistula. Chronic granulomatous inflammation is often a feature of dermoid cysts, contributing to local soft tissue and bony destruction. Isolated multicystic dermoids are not well described. We present a case of a multilobular dermoid characterized both radiographically and histopathologically. These findings may be attributed to repeated rupture and reformation of the dermoid cyst. When possible, our experience favours early excision of orbital dermoid cysts to minimize morbidity.
皮样囊肿在组织学上被定义为包裹内部管腔的表面上皮。文献中对它们有详细描述，为离散的单个肿块，呈圆形或哑铃形，有或无长期存在的瘘管。慢性肉芽肿性炎症通常是皮样囊肿的一个特征，可导致局部软组织和骨质破坏。孤立性多囊性皮样囊肿的描述并不充分。我们报告一例经影像学和组织病理学特征均得以明确的多叶状皮样囊肿。这些发现可能归因于皮样囊肿的反复破裂和重新形成。在可能的情况下，我们的经验支持早期切除眼眶皮样囊肿，以将发病率降至最低。
