Phosphaturic mesenchymal tumour, mixed connective tissue type, abbreviated PMTMCT, is a rare tumour.
General
- Extremely rare.
- Hypophosphatemia.[1]
- Most common cause of oncogenic osteomalacia (tumour-induced osteomalacia).[2]

Features:[2]
- Spindle cells without atypia in an eosinophilic matrix.
