Tumoral calcinosis in multiple digits: a case report

Area of Science:

• Orthopedics
• Rheumatology
• Dermatology

Background:

• Tumoral calcinosis typically affects large joints.
• Digital manifestation of tumoral calcinosis is exceptionally rare.
• Previous literature lacks reports of tumoral calcinosis in the digits.

Observation:

• A case of tumoral masses of hydroxyapatite in multiple digits is presented.
• The tumoral masses were located in the fingers.
• The patient presented with no identified causative metabolic or collagen-vascular disease.

Findings:

• The study documents a rare occurrence of tumoral calcinosis in the fingers.
• Histopathological analysis confirmed hydroxyapatite composition of the masses.
• No underlying metabolic or autoimmune conditions were found to be associated.

Implications:

• This case expands the known clinical spectrum of tumoral calcinosis.
• Highlights the importance of considering rare diagnoses in digital masses.
• Further research may be needed to understand the etiology of idiopathic digital tumoral calcinosis.
