Pseudocyst of the scalp is described in the Japanese literature as a skin-colored cystic tumor localized on the forehead, whereas alopecic and aseptic nodules of the scalp are described in the French literature as asymptomatic nodules on the scalp that lack a pseudocyst-like architecture. The etiology of these diseases is unknown, but the lesions are likely due to follicular occlusion. Here, we report a case of pseudocyst of the scalp in a 72-year-old woman. The patient had a dome-shaped painless tumor on her scalp. Histologic examination showed a pseudocyst-like architecture with no true cystic wall. Here, we report a case of pseudocyst of the scalp and summarize the characteristic features of both pseudocyst of the scalp and alopecic and aseptic nodules of the scalp.
头皮假性囊肿在日本文献中被描述为位于前额的肤色囊性肿瘤,而头皮脱发性无菌性结节在法国文献中被描述为头皮上无症状的结节,缺乏假性囊肿样结构。这些疾病的病因尚不清楚,但病变可能是由于毛囊堵塞。在此,我们报告一例72岁女性的头皮假性囊肿病例。患者头皮上有一个圆顶状无痛性肿瘤。组织学检查显示为假性囊肿样结构,无真正的囊壁。在此,我们报告一例头皮假性囊肿病例,并总结头皮假性囊肿以及头皮脱发性无菌性结节的特征。
