Background: X-linked reticulate pigmentary disorder is a very rare cutaneous condition characterized by different clinical manifestations according to sex.
Methods: We report a 31-year-old woman with X-linked reticulate pigmentary disorder.
Results: On examination, there were multiple, asymptomatic, brownish macules in linear and whorled patterns over the trunk, axillae, groin, and extremities. The woman had not experienced any systemic manifestations involving the gastrointestinal, pulmonary, or ocular systems. Her hair, teeth, and nails were normal on close observation. All laboratory data were within the normal range. A genetic study was not performed.
Conclusions: Although a genetic study was not performed, we believe that our patient can be diagnosed with X-linked reticulate pigmentary disorder according to the clinical and histopathologic findings.
