Sumario:INTRODUCTION: Systemic sclerosis is a systemic connective tissue disease with variable cutaneous presentations. Although pigmentary disturbances have been described in systemic sclerosis, a reticulate hyperpigmentation has only been reported in one case of systemic sclerosis to date. CASE PRESENTATION: We describe a previously healthy 51-year-old Thai woman who presented with a reticulate hyperpigmentation affecting her trunk and extremities, together with sclerodactyly and proximal sclerosis, resulting in a new diagnosis of systemic sclerosis. CONCLUSIONS: To date, the pathogenesis of reticulate hyperpigmentation in systemic sclerosis remains unclear. Increased melanin synthesis and altered thermoregulatory mechanism are proposed to be involved in the pathogenesis of this presentation. This case represents an unusual cutaneous feature of reticulate hyperpigmentation in the setting of systemic sclerosis.
