Phosphaturic mesenchymal tumour, mixed connective tissue type
Diagnosis in short
Site soft tissue, bone
Blood work low serum phosphate

Phosphaturic mesenchymal tumor is a rare tumour.

One type is the phosphaturic mesenchymal tumour, mixed connective tissue type, abbreviated PMTMCT.

General

  • Extremely rare.
  • Hypophosphatemia.[1]
  • Most common cause of oncogenic osteomalacia (tumour-induced osteomalacia).[2]

Gross

  • Soft tissue or bone.[3]
  • Often small - thus hard to identify.[4]

Microscopic

Features:[2]

  • Spindle cells without atypia in an eosinophilic matrix.
  • Osteoclast-type giant cells.
  • +/-Calcifications.
