Eosinophilic Fasciitis: A Rare and Challenging Diagnosis in a Free Clinic Setting.

Eosinophilic fasciitis (EF) is a rare ailment that affects the immune system. Due to the rarity of this condition, there are few clear diagnostic criteria for clinicians to focus on. This may lead to significant delays in reaching a diagnosis and offering proper treatment, and patients may end up seeing multiple different specialists. This is especially true in a free clinic setting where continuity of care, follow-up, and specialist access are usually lacking. In this report, we describe a case of a 24-year-old white male who presented with sudden onset of redness, swelling, burning, and pain in the bilateral upper and lower extremities. Through arduous workup and testing, he was found to have increased eosinophils in peripheral blood, elevated levels of white blood cell count, increased C-reactive protein, and pathological changes in the tissue showing eosinophil and lymphocyte infiltration. We shed light on the relative rarity of this condition and its similar clinical characteristics to various dermatological/rheumatological disease processes. We also highlight how a free clinic can provide high-quality healthcare to bridge gaps in access to care by providing high-quality and broad specialist access while ensuring continuity of care.
