Unicentric Castleman disease presenting as a longstanding axillary and chest wall mass: A case report

Unicentric Castleman disease, particularly the hypervascular variant subtype, commonly presents as a localized lymphadenopathy without systemic symptoms. Surgical excision is often curative for this subtype, leading to a good prognosis. However, some patients with autoimmune complications may require additional systemic therapy along with surgery. Accurate diagnosis through a combination of clinical, radiological, and pathological findings is crucial for optimal management.
