The clinical picture was consistent with a clinical diagnosis of ASIA, with breast implant rupture and/or vaccination against severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) as possible triggers. Histopathology of skin, oral nodules, and laryngeal nodules revealed cutaneous/mucous and submucosal infiltration of large epithelioid mononuclear or binucleated cells with fine granular ground glass-like cytoplasm and round to kidney-shaped nuclei with prominent nucleoli, without atypical features or relevant pleomorphism, accompanied by sparse giant cells and lymphocytes. These cells stained positive for CD68 and CD45 and negative for S100, CD1a, and markers of epithelial or neural/melanocytic differentiation, altogether consistent with a diagnosis of reticulohistiocytosis.

Diagnostic testing showed positive microvasculopathy on nailfold videocapillaroscopy (NVC) and positive fibrosis on skin biopsy.

Contrast-enhanced computed tomography showed poor perfusion of the right ulnar artery, and a heavy smoking history was established in the patient case. Therefore, based on Shionoya's criteria, he was diagnosed with a case of Buerger's disease confined to the upper extremity. Smoking cessation and vasodilator therapy resulted in the prompt resolution of ischaemic symptoms, skin hardening, and ulcerations.
