A Case of Persistent Subepidermal Calcified Nodule in an Adult Treated with CO₂ Laser

Abstract

A subepidermal calcified nodule (SCN) is an uncommon form of calcinosis cutis that is not associated with other dermatologic or systemic illnesses. Clinically, SCN presents as a solitary, firm tumor that can be white, white-yellow, or erythematous. Most SCNs occur in children; they are extremely rare in adults. The treatment of choice is believed to be surgical excision. We describe a case of SCN on the right ear lobe of a 33-year-old male, which was treated using a CO2 laser and electrodessication.

Multiple sub-epidermal calcified nodule mimicking eruptive xanthoma: A case report and review of the literature

“…[3] The lesion may recur following excision. [32526] Intra-lesional steroid injection[16] and CO 2 laser[25] have also have been used as alternative treatment modalities. [3]…”

Congenital calcinosis cutis of the foot

“…If small and multiple, electrodessication or CO2 laser ablation may be done. [9] Recurrence following surgical excision is uncommon. [10]…”

Four cases of subepidermal calcified nodule on a child’s sole

“…While excisional biopsy shows a high rate of complete recovery, incomplete incision may result in recurrence 10 . There are also reports of treating SCN with CO 2 laser 7,11 . It is known that the ablation of epidermal lesions with a CO 2 laser is better than surgical excision in cases of benign cutaneous tumors, because it results in less scar formation and facilitates bleeding control.…”
