Painful, Tender, Localized, Idiopathic Livedo Reticularis
Abstract
Livedo reticularis (LR) is a unique cutaneous condition characterized by a reddish-blue to purple, net-like cyanosis of the skin, often associated with disturbances in cutaneous blood flow. This case report discusses a 30-year-old woman with a history of Hashimoto thyroiditis, vitamin D deficiency, migraines, and goiter who presents with painful, localized LR on her right flank. Despite her extensive medical history, there were no significant findings in her laboratory and imaging studies, including a normal epidermis in skin biopsies. The LR in this case is distinguished by its persistence and the presence of pain, a symptom not commonly associated with LR. Various treatments, including 5% lidocaine ointment, oral analgesics, and gabapentin, were considered, but her symptoms remained stable over 13 months. This case exemplifies the complexity of LR, particularly when presenting with atypical symptoms like pain. It highlights the need for further research into the pathophysiology and treatment of LR, especially in cases deviating from the typical symptomatology, and suggests the potential value of a multi-disciplinary approach to management.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
