Facial Epidermal Inclusion Cysts Are Associated with Smoking in Men: A Hospital-Based Case-Control Study

Abstract

Smoking may contribute to the development of EICs.

Unilateral Favre-Racouchot Disease: Evidence for the Etiological Role of Chronic Solar Damage

“…Apparently, sun exposure exerts an aggravating effect in smoking-induced cyst development: a retrospective study on 301 patients showed that a greater percentage of patients with abnormal inclusion cysts were smokers (50%) than control subjects (27%). This difference was significant only for cysts located in the face, while extrafacial locations did not differ in this regard [13]. This observation is supported by in vitro findings where the phototoxic properties of tobacco smoke were enhanced by ultraviolet light [14].…”

A Case of Ruptured Perineal Epidermal Cyst

“…The most common type of epidermal cyst is a follicular infundibular cyst. Several factors may be responsible for epidermal cyst formation, including exposure to ultraviolet rays, human papilloma virus infection, smoking, and trauma (surgical cuts such as episiotomy or needle biopsies in the perineal region) [ 1 , 8 , 9 ]. Multiple epidermoid cysts can also be found in autosomal dominant Gardner syndrome (familial adenomatous polyposis) or Gorlin syndrome (basal cell nevus syndrome) [ 4 ].…”

Symmetric multilocular epidermoid cysts on the face: An unusual presentation of a common lesion

“…He also was a smoker, and a study that retrospectively surveyed 301 patients with facial epidermoid cysts found that men (and not women) with facial cysts were significantly more likely to be smokers compared with unaffected controls. 9 …”
