Summary
Calcinosis circumscripta, a rare condition causing mineral deposits, was diagnosed in a domestic short-haired cat. Surgical excision of the subcutaneous mass resulted in a complete recovery with no recurrence.
Area of Science:
- Veterinary Pathology
- Dermatology
- Mineral Metabolism Disorders
Background:
- Calcinosis circumscripta is a rare idiopathic condition characterized by the deposition of calcium salts in soft tissues.
- It typically presents as a nodular mass, often in subcutaneous or dermal locations.
- While documented in various species, it is less commonly reported in feline patients.
Observation:
- A poorly circumscribed, subcutaneous mass was identified on the dorsum of a young adult male domestic short-haired cat.
- The feline patient exhibited no other signs of illness or systemic compromise.
- The mass was surgically excised for diagnosis and treatment.
Findings:
- Histopathological examination revealed the mass was composed of multiple fragmented loculi.
- Each loculus contained a crystalline, light red center surrounded by dense, amorphous, mineralized material.
- Connective tissue stroma variably separated the mineralized loculi.
Implications:
- This case highlights calcinosis circumscripta as a differential diagnosis for subcutaneous masses in cats.
- Surgical excision appears to be an effective treatment modality for feline calcinosis circumscripta.
- Further research into the etiology and pathogenesis of this condition in felines may be warranted.
