Abstract
- Rudimentary menigocele is a developmental anomaly in which menigothelial elements are present in the skin and subcutaneous tissue. A 9-year-old boy presented with a well-circumscribed, central atrophic and alopecic patch on the midline of the occipital area, and this lesion had been present at birth. Histological examination showed dense collagen bundles with pseudovascular spaces lined by oval, spindle shaped cells in the dermis and the subcutaneous layer. Collagen bodies and psammoma body were also detected. On the immunohistochemistry, these oval, spindle shaped cells were positive for vimentin, but negative for CD31, EMA and S100 protein.
