RESUMEN
Background@#Mobile applications are useful in the field of dermatology as diagnosis and treatment are based on visual inspection. However, in Korea, dermatology-related applications have not been developed effectively despite the high rate of mobile internet usage. In addition, there is no report on the current trends of dermatology-related mobile application. @*Objective@#This study aimed to identify and categorize the available dermatology-related mobile application and compare the current trends in Korea with those in the US. @*Methods@#Eight dermatologic terms were queried in two mobile platforms, Android and iOS. Applications were categorized by function based on their description. The number of reviews, rating, provider, target audience, and price of applications were recorded. @*Results@#A total of 213 dermatology-related applications were identified. Approximately 10.8% of the applications were related to skin diseases, 23.5% were related to skin care, and 65.7% were others. Among the applications related to skin diseases, 4.2% were self-surveillance/diagnosis apps, 3.3% were disease guide and reference apps, and 1.4% were dermoscopy apps. No applications were related to educational aid and photography search. Among the applications related to skin care, 12.7% were self-surveillance/diagnosis apps used for general skin care, 3.8% were skin care apps, and 2.8% were cosmetics apps. Other categories included shopping (24.9%), advertisements (15.0%), and hospital searches (15.0%). @*Conclusion@#The development and use of dermatology mobile applications can contribute to the efficient delivery of accurate information to patients, educate patients, and further reduce the prevalence of skin diseases. Therefore, dermatologists should play a leading role in presenting the direction for dermatology-related mobile application development.
RESUMEN
Apocrine hidrocystoma, also called apocrine cystadenoma, is a benign cystic tumor-like lesion that arises from the proliferation of apocrine glands. Clinically, it usually occurs singly as a unilocular or multilocular, dome-shaped translucent cyst. Histologically, it appears as unilocular or multilocular cysts composed of an inner layer of single or double layer of secretory columnar epithelium with decapitation secretion lying above an outer myoepithelial cell layer. Apocrine hidrocystomas mostly occur within the head and neck region and involvement of genitalia is extremely rare. This paper emphasizes the importance of considering the differential diagnosis of a genital cystic lesion. Herein, we report a case of apocrine hidrocystoma occurring in the penis and compare the clinicopathological characteristics of apocrine hidrocystoma in genitalia with the previous cases.

Neutrophilic dermatoses comprise a wide spectrum of inflammatory diseases with overlapping features characterized histologically by the presence of an aseptic neutrophilic infiltrate in the epidermis, dermis, and/or hypodermis and are often associated with systemic inflammatory and neoplastic disorders. Here we report a case of a 75-year-old man who developed painful indurated plaques with a vesicular, bullous, and even hemorrhagic appearance similar to cellulitis on his right leg along with a fever that raised his body temperature up to 39℃ and malaise.

Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular proliferative process characterized by proliferation of endothelial cells with papillary formation located within a vascular lumen. It could manifest as a primary or pure form that develops in a distended vessel or it could be associated with hemangiomas, pyogenic granulomas, and/or lymphangiomas. We report a case showing development of intravascular papillary endothelial hyperplasia on a patient's right fifth finger.

Undifferentiated pleomorphic sarcoma, known as malignant fibrous histiocytoma, is a malignant neoplasm that arises in both soft tissue and bones. In 2002, the World Health Organization declassified malignant fibrous histocytoma as a formal diagnostic entity and renamed it 'undifferentiated pleomorphic sarcoma not otherwise specified.' It most commonly occurs in the lower extremities and rarely metastasizes cutaneously. We report a case of cutaneous metastatic undifferentiated pleomorphic sarcoma of the buttocks occurring in a 73-year-old man diagnosed with mediastinal sarcoma 4 years previously. He first noticed the mass approximately 2 months previously. Histological findings with immunomarkers led to a final diagnosis of cutaneous metastatic sarcoma from mediastinal undifferentiated pleomorphic sarcoma.

BACKGROUND: The internet is a growing source of information for patients, with increasing numbers of people searching for health information on the web. Patients with acne attempt to search for medical information from the internet. OBJECTIVE: The purpose of this study is to investigate the current information of acne on the internet. METHODS: We chose the largest portal sites to investigate the current information of acne and search for 'acne'. RESULTS: 5.3% of the information provided by question-and-answer platform were written by dermatologist. 0.7% of the information provided by personal blog were written by dermatologist. 1.4% of the information provided by internet message board were written by dermatologist. Overall, only 2.4% of the information were written by dermatologist for provide the medical information. CONCLUSION: The internet provides a great deal of information in many types of resources. However, the quality of information has been more of a concern. Dermatologists should continue to counteract inaccurate information by providing quality information on the internet. Dermatologists should be more aware of the health-related online information and should guide patients to take the accurate information.

BACKGROUND: The incidence of scalp tumors has increased, despite medical advances and environmental improvement. However, few studies have reported the clinical and histopathologic features of scalp tumors. OBJECTIVE: The purpose of this study was to evaluate the clinical and histopathologic features of scalp tumors. METHODS: We retrospectively reviewed the clinical and histopathologic features and occurrence rates of scalp diseases in 418 patients whose lesions were biopsied in the department of dermatology between January 2004 and December 2013. RESULTS: The mean age of patients exhibiting scalp tumors was 44.9 years old. The male to female ratio was 1:0.69. The most common benign scalp tumor diagnosed was seborrheic keratosis (22.6%) followed by epidermal inclusion cyst (15.3%), intradermal nevus (8.7%), sebaceous nevus (7.1%), actinic keratosis (5.2%), pyogenic granuloma (3.0%), neurofibroma (2.5%), compound nevus (2.2%), epidermal nevus (1.1%), dermatofibroma (1.1%), and hemangioma (1.1%). The most malignant scalp tumor diagnosed was basal cell carcinoma (34.6%) followed by squamous cell carcinoma (32.7%), metastatic cancer (11.5%), angiosarcoma (7.7%), Bowen's disease (7.7%), lymphoma (3.8%), and apocrine adenocarcinoma (1.9%). CONCLUSION: This study provides data on the incidence of scalp tumors. The results of our study were different from previous studies possibly owing to regional differences between reported patient populations. We advise physicians to appropriately diagnose and treat scalp tumors at the earliest suspicion of malignancy.
