AI Article Synopsis

  • Tumoral calcinosis (TC) is a rare inherited condition that leads to the development of calcified masses around joints and has limited reports on aspiration cytology findings.
  • A case study of a 35-year-old man with a history of TC revealed a mass in his shoulder, which was ultimately diagnosed as an extraabdominal desmoid fibromatosis, showing the potential for misdiagnosis.
  • Recognizing the specific characteristics of TC in aspiration cytology can prevent misinterpretation and aid in accurate diagnosis.

Article Abstract

Background: Tumoral calcinosis (TC) is a rare inherited disorder leading to the formation of periarticular calcified masses. Aspiration cytology of this condition has been rarely reported. We describe the aspiration cytology findings of a recent case of TC and discuss possible differential diagnoses.

Case: This is a case of a 35-year-old African-American man who presented with a right posterior chest/shoulder mass. The patient had a history of resection of right shoulder (1996) and left neck (2007) masses histologically diagnosed as TC. He recently also had a right-side neck mass that, surprisingly, was found to be extraabdominal desmoid fibromatosis on histologic examination.

Conclusion: Inherited idiopathic TC is a rare disease commonly presenting as a periarticular mass, which may be subjected to aspiration biopsy. Awareness of this distinct entity and the aspiration cytologic features helps avoid incorrect interpretation.
