Summary
Encephalocraniocutaneous lipomatosis is linked to a unique hairless, fatty scalp nevus, now named nevus psiloliparus. This distinct skin condition is characterized by specific clinical and histopathological features.
Area of Science:
- Dermatology
- Medical Genetics
- Pathology
Background:
- Encephalocraniocutaneous lipomatosis is associated with a distinct scalp fatty tissue nevus.
- This nevus, characterized by a smooth, hairless surface, has not been previously recognized as a separate cutaneous entity.
Purpose of the Study:
- To describe the characteristic features of this nevus.
- To propose a specific name for this distinct cutaneous disorder.
Main Methods:
- Analysis of two patient cases.
- Comprehensive review of existing medical literature.
- Delineation of clinical and histopathological criteria.
Main Results:
- A new term, 'nevus psiloliparus' (from Greek for hairless and fatty), is proposed.
- Nevus psiloliparus is distinguished by scalp localization, smooth surface, absence of hair follicles, and isolated arrector pili muscles.
- It is differentiated from Hoffmann-Zurhelle nevus, which is not observed in encephalocraniocutaneous lipomatosis cases.
Conclusions:
- Current data suggest nevus psiloliparus is a distinct cutaneous entity.
- Further clinical and genetic research is needed to confirm this classification.
