Phakomatosis pigmentovascularis is a rare neurocutanous condition where there is coexistence of a capillary malformation (port-wine stain) with various melanocytic lesions, including dermal melanocytosis (Mongolian spots), nevus spilus, and nevus of Ota.
Types
Phakomatosis pigmentovascularis is subdivided into five types:Freedberg, et al. (2003). Fitzpatrick's Dermatology in General Medicine. (6th ed.). Page 1012. McGraw-Hill. {{ISBN|0-07-138076-0}}.{{cite book |author=Rapini, Ronald P. |author2=Bolognia, Jean L. |author3=Jorizzo, Joseph L. |title=Dermatology: 2-Volume Set |publisher=Mosby |location=St. Louis |year=2007 |isbn=978-1-4160-2999-1 }}
- Type 1 PWS + epidermal nevus
- Type 2 (most common): PWS + dermal melanocytosis +/- nevus anemicus
- Type 3: PWS + nevus spilus +/- nevus anemicus
- Type 4: PWS + nevus spilus + dermal melanocytosis +/- nevus anemicus
- Type 5: CMTC (Cutis marmorata telangiectatica congenita) + dermal melanocytosis
They all can contain capillary malformation. Type 2 is the most common and can be associated with granular cell tumor. Some further subdivide each type into categories A & B; with A representing oculocutaneous involvement and subtype B representing extra oculocutaneous involvement. Others have proposed fewer subtypes but currently this rare entity is mostly taught as having five subtypes currently.{{citation needed|date=September 2020}}
