Introduction: Developmental topographical disorientation (DTD) is a lifelong condition in which affected individuals are selectively impaired in navigating space. Although it seems that DTD is widespread in the population, only a few cases have been studied from both a behavioral and a neuroimaging point of view. Here, we report a new case of DTD, never described previously, of a young woman (C.F.) showing a specific deficit in translating allocentrically coded information into egocentrically guided navigation, in presence of spared ability of constructing such representations.

We report Developmental Landmark Agnosia (DLA) in a 6-year-old boy (L.G.) who was referred to
us for congenital prosopagnosia (see Pizzamiglio et al., 2017, in which both testing and
rehabilitation of Congenital Prosopagnosia are reported). We investigated his performance using a
neuropsychological battery and eye movement recordings. The assessment showed the presence
of deficits in recognizing familiar places (along with Congenital Prosopagnosia), but not common
