RESUMO
Background@#The forehead is a region connected to the scalp and is accompanied by various structures. In some tumors, the pattern of development may differ from that of other anatomical sites. When a noninflammatory skin-colored tumor develops on the forehead, it is difficult to diagnose accurately. @*Objective@#This study aimed to identify the epidemiologic data and clinical features of noninflammatory skin-colored tumors of the forehead. @*Methods@#We retrospectively reviewed the medical records of 200 patients with noninflammatory, skin-colored tumors diagnosed after skin biopsy over a period of 11 years. We evaluated tumor prevalence, clinical features, and differences according to sex and age. If the tumor was large and deeply located, a radiologic study was performed. @*Results@#Of the 12 different histopathologic results, lipoma (52.0%) was the most frequent, followed by epidermal cyst (17.0%), osteoma (13.5%), steatocystoma (6.0%), and pilomatricoma (3.5%). Statistical analysis showed that females were dominant in the osteoma group. For an accurate diagnosis, 25 of the 52 patients who underwent computed tomography were diagnosed with lipoma, and 19 (76.0%) of them were identified as deep-seated lipoma. @*Conclusion@#The most common tumor among noninflammatory, skin-colored tumors of the forehead was lipoma.When they occur on the forehead, the proportion of deep-seated lipomas is higher than that at other sites. In the case of a solid and fixed tumor, a deep-seated lipoma should be considered. Computed tomography should be performed in addition to ultrasonography because the sensitivity of ultrasonography for the diagnosis of deep-seated lipoma is unsatisfactory.
RESUMO
Juvenile temporal arteritis (JTA) is a non-giant cell inflammation of the temporal artery, characterized by eosinophilic infiltration. It generally affects both adolescents and young adults. JTA is clinically represented by an asymptomatic, palpable lump in the temporal area, with no associated signs, such as fever, myalgia, or visual symptoms. A 38-year-old female presented to our hospital with a history of bilateral linear plaques in both temporal areas for 3 months. Histopathological findings of the right temporal lesion showed infiltration of eosinophils and lymphocytes in the arterial wall and intimal hyperplasia but no giant cell or granulomatous lesions. Doppler ultrasonography revealed a tortuous tubular anechoic lesion, with non-visualization of internal vascular flow. Laboratory findings highlighted eosinophilia of up to 13.8% and a total immunoglobulin E level of 1,182 IU/mL. Here, we report a rare case of bilateral JTA with eosinophilia.
RESUMO
Background@#Cellulitis is one of the most common infectious skin diseases treated by hospitalization, and presents with various clinical features and treatment responses. Therefore, more detailed analysis on this condition is required. @*Objective@#To investigate the clinical characteristics of cellulitis among dermatology inpatients in a single center. @*Methods@#We retrospectively reviewed the medical records of 84 patients hospitalized with cellulitis between January 2012 and August 2020. We analyzed the differences by dividing them into ＜60-year-old and ＞60-year-old age groups. @*Results@#The average age of the 84 inpatients in this study was 48.8 years with the peak incidence in fifties.Cellulitis was most prevalent in the calf (39.8%). Erythrocyte sedimentation rate (ESR) and risk factors such as obesity and smoking had positive correlations with duration of hospital stay (p＜0.05). There was no significant difference in duration of hospital stay between those administered first-generation cephalosporin and other antibiotics. @*Conclusion@#Our data showed that ESR, obesity, and smoking were correlated to the hospitalization periods. In particular, it showed positive correlation of C-reactive protein and ESR with duration of hospital stay in those below the age of 60 years.

RESUMO
Diabetic radiculoneuropathy is an uncommon complication of diabetes mellitus that can affect the cervical, thoracic, or lumbosacral nerve roots. When the thoracic nerve roots are affected, it can cause truncal pain and, more rarely, abdominal bulging. A 62-year-old man with diabetes developed sudden pain in his right abdomen with subsequent distention overlying the area for 10 days. Neither vesicular eruptions nor cutaneous scarring was noted. Imaging scans of the abdomen and spinal cord did not reveal any other causes of abdominal distention. Needle electromyography showed evidence of radiculoneuropathy in the right thoracic regions (T6 through T9), and nerve conduction study of the upper and lower extremities also showed evidence suggestive of severe distal symmetric polyneuropathy. With the exclusion of any apparent causes of abdominal distention, a diagnosis of diabetic radiculoneuropathy was made.

RESUMO
Metastatic skin cancers are a relatively uncommon malignant tumor. Visceral tumors such as breast, lung, and colon cancers are commonly found to be the primary origin. Cutaneous metastasis with esophageal cancer is exceedingly rare, accounting for less than one percent of all skin metastasis. Here, we report a case of cutaneous metastatic squamous cell carcinoma that originated from esophageal carcinoma. The patient was a 48-year-old male who complained of a 2-cm-sized non-tender, skin-colored nodule on his left lower back. Positron emission tomography-computed tomography (PET-CT) showed focal fluorodeoxyglucose (FDG) uptake in the lesion. In the histopathological examination, the tumor cells stained positive for epithelial membrane antigen (EMA) and cytokeratin 5/6 (CK5/6), which was consistent with squamous cell carcinoma. This case suggests that patients who have been treated for primary esophageal carcinoma should undergo a skin biopsy to rule out metastatic skin cancer if the tumor appears to be suspicious.
