title: Subcutaneous rhinosporidiosis masquerading as soft tissue tumor: diagnosed by fine-needle aspiration cytology.
abstract: Rhinosporidiosis is a chronic granulomatous lesion caused by Rhinosporidium seeberi. It frequently involves nasopharynx and ocular region. Presenting as cutaneous and subcutaneous mass is extremely rare. This report describes the FNA cytology of rhinosporidiosis occurring as a soft tissue mass in the right mid thigh region. We present a rare case of a 71-year-old male, who presented with multiple subcutaneous soft tissue mass lesions in the posteromedial aspect of mid right thigh region since 2 weeks. Local examination revealed multiple firm to hard mass with skin over the swelling was unremarkable. CT of the right thigh showed a heterogeneous lesion with infiltrative margins in the thigh. Clinically soft tissue sarcoma was considered. Diagnostic FNAC was performed showing numerous mature and immature sporangias with giant cell reaction. Hence, an excision biopsy confirmed the rhinosporidiosis. To conclude, the FNAC diagnosis of rhinosporidiosis is specific. Preoperative diagnosis is possible even in cases with unusual clinical presentations.
