A swollen ankle
after a long walk, and seven months of being told it was nothing.
December 2023. Twenty-six years old, six months into my first IT job. My left ankle swelled after an evening walk — not a sprain, no injury, just a hard, board-like swelling that did not pit. I assumed it would resolve. It did not.
By February 2024 the swelling had crept up the calf and the skin of my forearms had begun to feel taut, as if I were wearing a tight long-sleeved shirt under my own skin. Range of motion at the wrists collapsed: I could no longer fold my hands in prayer position. A general practitioner suggested a fungal infection. An orthopaedist suggested overuse. A dermatologist suggested scleroderma and ordered an ANA panel — it came back negative, and the trail went cold.
What broke the diagnostic stalemate was a peripheral blood count from May 2024 showing absolute eosinophilia of roughly 2,200 / µL — well above the 500 / µL upper limit of normal. A rheumatologist at a tertiary centre saw the count alongside the skin findings, ordered an MRI of both forearms with T2-STIR and post-contrast sequences, and read the result herself: hyperintense thickening of the deep fascia with avid post-contrast enhancement. The full-thickness skin-to-muscle biopsy that followed two weeks later confirmed it — Shulman's eosinophilic fasciitis. ICD-10 M35.4.
Eight months from first symptom to diagnosis. That is faster than the literature average for this disease (median diagnostic delay in the published cohorts sits closer to 11 months, with a wide tail). It still felt like a year. This page exists so the next person does not have to walk that path blind.
From first symptom to fourth line.
First symptom
Unilateral, hard, non-pitting swelling of the left ankle after a long evening walk. No trauma, no fever, no rash. Self-resolution expected; none observed over six weeks.
Spread, and the first three doctors
Symmetric forearm tightening, loss of wrist flexion, palpable induration of the calves. GP, orthopaedist and dermatologist seen sequentially over five weeks. Working diagnoses: fungal cellulitis, overuse strain, early scleroderma. ANA negative, anti-Scl-70 negative, anti-centromere negative.
Peripheral eosinophilia of 2,200 / µL
Complete blood count ordered as part of a routine follow-up. Absolute eosinophil count flagged. Differential pivoted from connective-tissue disease towards an eosinophilic disorder. Referral to rheumatology accepted within two weeks.
MRI of forearms and lower limbs
T2-STIR and post-contrast T1 sequences of both forearms and both calves. Reading rheumatologist documented hyperintensity and thickening of the deep fascia, with avid post-contrast enhancement — the imaging signature of fasciitis (Moulton 2005; Wright 2016). Muscle and subcutaneous tissue spared.
Full-thickness fascial biopsy
Skin-to-muscle wedge biopsy of the right forearm under local anaesthesia, performed by an orthopaedic surgeon at a tertiary university hospital. Histopathology: thickened, inflamed fascia with a dense lymphoplasmacytic and eosinophilic infiltrate, sparing the dermis and the muscle. Diagnostic conference: eosinophilic fasciitis, ICD-10 M35.4.
First line — oral prednisolone 1 mg/kg/day
Standard first-line therapy (Lakhanpal 1988, every subsequent cohort). Eosinophil count normalised within four weeks; skin tightening partially regressed. Taper attempt below 20 mg / day at month six provoked recurrence of forearm induration. Cumulative cushingoid features documented at month seven.
Second and third lines — methotrexate, then mycophenolate
Subcutaneous methotrexate 20 mg / week added as a steroid-sparing agent (Wright 2016 evidence base). Partial response, transaminase elevation at month eight forced a switch to mycophenolate mofetil 2 g / day. Steroid taper achieved 7.5 mg / day maintenance.
Fourth line — rituximab off-label
Two 1 g infusions, two weeks apart (rheumatoid arthritis protocol applied off-label per published EF case series, e.g. Pinal-Fernandez 2014, Mango 2020). B-cell depletion confirmed at week 6. Forearm range of motion improving as of the most recent clinic visit. Status: active disease, ongoing.

Ten admissions, ten letters.
Fascial biopsy of the right forearm, full diagnostic work-up, initiation of oral prednisolone 1 mg/kg/day. Histopathology confirmed eosinophilic fasciitis.
Methylprednisolone 1 g IV × 3 days as a bridging treatment alongside oral prednisolone. No adverse events. Eosinophil count maintained within normal range.
Subcutaneous methotrexate 15 mg/week started under inpatient observation; folic-acid supplementation; baseline LFTs documented.
ALT 184 U/L, AST 142 U/L. Methotrexate paused; hepatology consult; viral hepatitis serology negative; resolution within 14 days. Decision to switch to mycophenolate.
MMF 1 g BID started inpatient. Baseline serology, CMV-PCR negative. Prednisolone taper continued to 7.5 mg/day.
Day-hospital physiotherapy programme for joint contracture maintenance — passive range-of-motion, aquatic therapy, ultrasound. Discharge with home exercise plan.
Clinical examination, MRI re-imaging, decision conference. Recurrence of forearm induration despite MMF + steroid maintenance. Plan: switch to rituximab.
Rituximab 1 g IV with standard premedication (paracetamol, antihistamine, methylprednisolone 100 mg IV). Infusion tolerated; no reaction. Observation 4 h post-infusion.
Second rituximab 1 g IV two weeks after the first. Uneventful infusion. CD19 B-cell count to be checked at week 6.
B-cell depletion confirmed (CD19 < 1 %). Forearm range of motion improving on clinical examination. Continued MMF and low-dose prednisolone. Next reassessment scheduled for autumn 2026.
Six photographs, two years.
Four lines, in the order they were tried.
Oral prednisolone 1 mg/kg/day, tapered
Eosinophil count normalised at week 4. Skin tightening regressed ~50 % at month 6. Taper below 20 mg/day provoked recurrence at month 6.
Methotrexate 20 mg/week subcutaneous
Partial steroid-sparing effect. Transaminase rise (ALT 184) at month 6 forced discontinuation.
Mycophenolate mofetil 2 g/day
Tolerated. Allowed prednisolone taper to 7.5 mg/day. Disease activity stable for ~4 months then recurred.
Rituximab 1 g × 2 infusions, off-label
B-cell depletion confirmed. Early clinical improvement at week 6. Reassessment planned at month 6.

Publishing my own case is the price of
asking other patients to publish theirs.
There are perhaps thirty published case series of eosinophilic fasciitis in the global literature, totalling around three hundred cases — for a disease that has existed clinically since Shulman described it in 1974. The reason is not that patients are rare; the reason is that case data is hard to publish, hard to share, hard to redact, hard to defend legally. So the data sits in hospital archives and dies there.
This page is the simplest fix I could think of. One patient, one full record, one persistent web page. If even one of the next hundred patients gets diagnosed faster because their rheumatologist read this, the work is paid for.
