Benign Chondroid Syringoma on Chin: A Case Report and Literature Review

Garima Anandani et al. Cureus. .

Abstract

Chondroid syringoma is a cutaneous adnexal tumor originating from sweat glands origin. It is rare in occurrence and usually benign, having an incidence of 0.01 to 0.098%. As these tumors are uncommon, their diagnosis is missed many times and are misdiagnosed. Hence in any case of facial skin swelling increasing slowly in size, this entity should be kept in mind as one of the possibilities and differential diagnosis. Histopathological examination of the excision biopsy gives the definitive confirmatory diagnosis. Surgically excising the swelling locally along with a surrounding normal tissue cuff is the standard treatment given which prevents recurrence. Hereby we present a 35-year-old case of facial chondroid syringoma having a focal component of eccrine hidrocystoma, keratinous cyst as well as syringocystadenoma papilliferum on the chin that was clinically suspected to be an epidermoid cyst or mucocele.

Keywords: benign skin adnexal tumour; chondroid syringoma; epithelial and mesenchymal; mixed tumour; multiple components.
