Dermatofibroma, also known as cutaneous benign fibrous histiocytoma, is a common skin tumour.
The aim of this paper was to present a rare variant of dermatofibroma, atrophic dermatofibroma, emphasizing histopathological and dermoscopic features.
PATIENTS/METHODS: A case of atrophic dermatofibroma in a female patient with the characteristic histopathological features and newly demonstrated dermoscopic findings is presented.
A 54-year-old female presented with a depressed reddish lesion on the back showing histopathological findings of atrophic dermatofibroma. The dermoscopy of the lesion revealed a peripheral pigment network surrounding a pink-reddish colouration around a central whitish scar-like patch with white-yellow scales which was not an exact match with the description in the literature.
Atrophic dermatofibroma is a rare variant that presents as an atrophic, depressed skin lesion which can easily be overlooked. Atrophic dermatofibroma should be considered in the differential diagnoses of atrophic, depressed lesions on the upper body of middle-aged women. The case of atrophic dermatofibroma presented here showed typical histopathologic findings with atypical dermoscopic features.
纤维瘤又名皮肤良性纤维组织细胞瘤，是一种常见的皮肤肿瘤。
本文旨在介绍一种纤维瘤的罕见变异型——萎缩性纤维瘤，强调其组织病理学和皮肤镜下特征。
病例/方法：我们报告了 1 例发生于女性患者背部的萎缩性纤维瘤，其具有特征性的组织病理学表现和新发现的皮肤镜下特征。
一位 54 岁女性因背部出现一红色凹陷性皮损就诊，组织病理学检查发现为萎缩性纤维瘤。皮损的皮肤镜检查显示，边界清楚的粉红色至红色区域，环绕着一个中央白色瘢痕样斑块，周围有色素网，中央有白色-黄色鳞屑，与文献中的描述不完全相符。
萎缩性纤维瘤是一种罕见的变异型，表现为萎缩性、凹陷性皮肤病变，容易被忽视。对于中年女性上半身出现萎缩性、凹陷性皮损时，应考虑萎缩性纤维瘤的鉴别诊断。本文报道的萎缩性纤维瘤病例表现出典型的组织病理学特征和非典型的皮肤镜下特征。
