An Unusual Case of Facial Steatocystoma Multiplex: A Clinicopathologic and Dermoscopic Report

Aseem Sharma et al. Dermatopathology (Basel). .

Abstract

Background: Steatocystoma multiplex is a benign skin disorder originating from the sebaceous and nevoid ducts. Commonly classified under hamartomas, they are distributed over the trunk, neck, axillae, and groin.

Methods: A 28-year-old male patient complained of multiple, asymptomatic skin-colored nodules over the face of 10-year duration. Clinical examination confirmed the historic findings of nontender, polysized, flesh-colored papules and nodules over the said distribution.

Results: On histopathology, a cyst was noted in the mid-dermis, lined by stratified squamous, agranular epithelium, which contained degenerated keratin. Nonpolarized dermoscopy showed a structureless, cream-colored area, and polarized dermoscopy revealed a distinctive, well-circumscribed, yellowish hue which was superimposed over the facial pseudoreticular pigmentary pattern. The findings were compatible with steatocystoma multiplex, and the patient was taken up for radiofrequency ablation.

Conclusion: Herein, we report a rare variant of steatocystoma multiplex limited to the face and scalp subjected to dermatoscopy and characteristic histological correlation. To the best of our knowledge and following a literature search, dermoscopic features of this condition have not been reported thus far.

Keywords: Dermoscopy; Facial steatocystoma multiplex; Hamartoma; Sebaceous gland.
