Abstract

Malignancy in a setting of hyaline vascular type of Castleman’s disease (HVCD) is an exceptional occurrence. Herein, we report an extremely rare case of synchronous unicentric cervical HVCD and squamous cell carcinoma (SCC) of tongue mimicking stage IV disease. A 32-year-old gentleman presented with an ulcerated mass on the right tongue border and ipsilateral cervical nodal mass. As the clinical stage was IVB (T1N3M0), an anterior two-third glossectomy with bilateral modified neck dissection was performed. On gross examination, an ulcerated mass on the right lateral border was identified. In addition, an 8 cm large nodal mass at right level III–V was seen. Microscopy from the ulcerated growth in the tongue revealed an invasive well differentiated squamous cell carcinoma. However, the right cervical nodal mass yielded surprise histology of Castleman’s disease, hyaline-vascular type. Final tumor pathological staging was revised to pT1N0M0. This case reveals that HVCD can rarely be associated with an epithelial malignancy wherein it can clinically mimic nodal metastasis. Whether such a phenomenon occurs due to underlying immune aberrations or is a rare co-incidence remains unclear
