Clinico-cytomorphological Spectrum of Calcinosis Cutis.

INTRODUCTION

The deposition of calcium in the skin is known as calcinosis cutis. It can affect any part of the body and can mimic soft tissue or bony lesions clinically.

AIM: To describe the clinical and cytomorphologic features of calcinosis cutis on fine needle aspiration cytology smears.

MATERIALS AND

METHODS

A total of 17 cases reported as calcinosis cutis on fine needle aspiration cytology were reviewed for the available clinical and cytological details.

RESULTS

The cohort included both adult and pediatric patients. Clinically, the lesions appeared as painless swellings of variable sizes. The common sites affected were the scrotum, iliac region, scalp, pinna, neck, axilla, elbow, arm, thigh, and gluteal region. Aspirate was chalky white, paste-like in all the cases. The cytologic evaluation revealed amorphous crystalline deposits of calcium along with histiocytes, lymphocytes, and multinucleated giant cells.

CONCLUSIONS

Calcinosis cutis has a wide spectrum of clinical presentations. Fine needle aspiration cytology is a minimally invasive approach for diagnosing calcinosis cutis, thus eliminating the need for more extensive biopsy procedures.
