Pseudocyst of the Scalp

چکیده
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.

histopathology does not always reveal pseudocysts. However, Sang Sing and coworkers argue that the 2 are distinct conditions, as biopsies reveal pseudocysts in the latter but not in the former. In conclusion, AANS is an emerging entity in the literature, is relatively unknown, and thus is likely underdiagnosed. It is diagnosed by the presence of alopecic, aseptic nodules on the scalp and the ab...
