 Triangular temporal alopecia, also referred to as congenital temporal alopecia, may be a non-scarring sort of hair loss usually seen on the frontotemporal scalp. The explanation for triangular temporal alopecia is unknown. It's usually sporadic but has been reported to run in families, suggesting a possible genetic link. Triangular temporal alopecia has been reported during a number of genetic conditions, including mongolism and phacomatosis pigmentovascularis. Many believe the condition is under-reported thanks to affected individuals not presenting with symptoms. Misdiagnosis of triangular temporal alopecia as alopecia , male pattern alopecia, traction alopecia, trichotillomania, or congenital aplasia cutis would also contribute to the impression of rarity. Triangular temporal alopecia appears as a triangular or spear-shaped loss of hair, with the ‘point’ of Triangulum directed up and back. The form is usually round or oval. it always doesn't cause any symptoms, but sometimes patients report dysaesthesia within the lesion. The lesion most ordinarily appears on the temporal scalp on one side only, although can affect each side . Involvement of the occipital hairline has also been reported.
