Reticulate acropigmentation of Kitamura: a case report

Area of Science:

• Dermatology
• Clinical Genetics
• Histopathology

Background:

• Reticulate acropigmentation of Kitamura (RAK) is a rare genodermatosis.
• RAK typically presents with reticulated hyperpigmentation on the distal extremities.
• Most reported cases are of Japanese ethnicity.

Observation:

• A Turkish female patient from Eastern Anatolia presented with clinical and histopathological features consistent with RAK.
• The patient's brother exhibited similar clinical signs but declined biopsy.
• No other family members displayed comparable dermatological findings.

Findings:

• The case provides clinical and histopathological documentation of RAK.
• This report expands the known ethnic diversity of RAK.

Implications:

• Further research into RAK in non-Japanese populations is warranted.
• Understanding RAK's presentation across diverse ethnicities can improve diagnosis.
• This case contributes to the literature on rare skin conditions.
