Management of epidermal cysts arising from scar tissues: A retrospective clinical study

Few reports have described epidermal cysts (ECs) arising from scar tissues, and the standard course of treatment has not been established. We aimed to report the findings of a Korean patient series with ECs arising from scar tissues, to describe patient management in the context of previous publications, and to present a simple algorithm for managing ECs arising from scar tissues.We managed 6 patients with ECs arising from scar tissues, and retrospectively reviewed their demographic and clinical data.The scars were located on the anterior chest wall (n = 3), shoulder (n = 1), forehead (n = 1), and ear lobule (n = 1). Two patients with anterior chest wall scars, 1 with a shoulder scar, and 1 with an ear lobule scar had keloid scars, whereas the other patients had hypertrophic scars. The scar sizes ranged from 2 × 1 cm to 9 × 7 cm. The EC sizes ranged from 0.2 × 0.2 cm to 2 × 1.5 cm. Three patients underwent total scar revisions with complete EC excisions, 2 underwent partial scar tissue excisions with complete EC excisions, and 1 had laser therapy for the scar and EC. No complications occurred, and all patients' final outcomes were satisfactory during the mean follow-up period of 14.8 months.We successfully managed the patients with ECs arising from scar tissues. We recommend that surgeons and patients first decide whether the ECs and scar tissue should be completely removed. Moreover, consideration should be given to the options chosen for the management of ECs. Finally, postoperative scar care is necessary to prevent hypertrophic and keloid scar recurrences.

What Do Germans Want to Know About Skin Cancer? A Nationwide Google Search Analysis From 2013 to 2017

Background

Experts worldwide agree that skin cancer is a global health issue, but only a few studies have reported on world populations’ interest in skin cancer. Internet search data can reflect the interest of a population in different topics and thereby identify what the population wants to know.

Objective

Our aim was to assess the interest of the German population in nonmelanoma skin cancer and melanoma.

Methods

Google AdWords Keyword Planner was used to identify search terms related to nonmelanoma skin cancer and melanoma in Germany from November 2013 to October 2017. The identified search terms were assessed descriptively using SPSS version 24.0. In addition, the search terms were qualitatively categorized.

Results

A total of 646 skin cancer-related search terms were identified with 19,849,230 Google searches in the period under review. The search terms with the highest search volume were “skin cancer” (n=2,388,500, 12.03%), “white skin cancer” (n=2,056,900, 10.36%), “basalioma” (n=907,000, 4.57%), and “melanoma” (n=717,800, 3.62%). The most searched localizations of nonmelanoma skin cancer were “nose” (n=93,370, 38.99%) and “face” (n=53,270, 22.24%), and the most searched of melanoma were “nails” (n=46,270, 70.61%) and “eye” (n=10,480, 15.99%). The skin cancer‒related category with the highest search volume was “forms of skin cancer” (n=10,162,540, 23.28%) followed by “skin alterations” (n=4,962,020, 11.36%).

Conclusions

Our study provides insight into terms and fields of interest related to skin cancer relevant to the German population. Furthermore, temporal trends and courses are shown. This information could aid in the development and implementation of effective and sustainable awareness campaigns by developing information sources targeted to the population’s broad interest or by implementing new Internet campaigns.
