Recurrent primary hyperphosphatemic tumoral calcinosis: a case report

Area of Science:

• Medical Science
• Pathology
• Radiology

Background:

• Tumoral calcinosis (TC) is a rare idiopathic condition characterized by extensive non-osseous calcification.
• It primarily affects adolescents and young adults, often in periarticular soft tissues of major joints.

Observation:

• A young female patient presented with recurrent subcutaneous swellings.
• Elevated serum phosphorus with normal serum calcium levels were noted.
• Clinical and radiological findings were suggestive of TC.

Findings:

• Cytologic and histopathologic studies confirmed the diagnosis of tumoral calcinosis.
• Positive von-Kossa stain confirmed calcium deposits, solidifying the diagnosis.
• The case presented typical clinical, radiological, and histopathological features of TC.

Implications:

• This case underscores the importance of recognizing the characteristic features of tumoral calcinosis.
• Accurate diagnosis relies on a combination of clinical presentation, imaging, and histopathology.
• Further research into the obscure etiology of TC is warranted.
