Myxoid solitary fibrous tumour of the axilla.
Mostly occurring in pleura, solitary fibrous tumour is an unusual soft tissue neoplasm. Solitary Fibrous Tumour with abundant myxoid stroma represents a rare morphologic subtype of the already uncommon tumour. We report a myxoid solitary fibrous tumour of the soft tissue in a 42-year-old man. The patient presented with a large, movable, nontender mass at the right axilla. The MRI showed a well-defined tumour with increased signal after gadolinium injection. During surgery, the mass was found to be closely associated with the axillary vein. The tumour was completely excised. Pathological and immunohistochemical examinations identified the mass as a myxoid solitary fibrous tumour. The patient was free of tumour recurrence at 18-month follow-up. The rare tumour in an uncommon location makes the diagnosis difficult. Complete excision and long-term follow up are recommended.
