Abstract
Seborrheic keratosis(SK) is a very common skin tumor which is mostly frequently observed in the trunck, head, neck. SK in the auricle is rare and this condition should be excluded the possibility of malignancy by pathologic diagnosis. We report a case of 66-year-old man who presented with a brownish, papillomatous, verrucous mass in the auricle for the past seven years, which began to growing faster during the previous year. Dermoscopy and histopathological examination were performed and the patient was diagnosed with SK. He was treated with the carbon dioxide(CO2) laser and aminolevulinate photodynamic therapy (ALA-PDT). The CO2 laser was used for the removal of the thick hypertrophic lesions and to enhance the transdermal absorption efficiency of ALA. A 20% ALA cream(118 mg/cm2) was applied to his lesion and sealed for 3 h without light, followed by irradiation with 630-nm LED light (96 J/cm2, 80 mw/cm2). We use fluorescent diagnosis with aminolevulinic acid to define the tumor margins at the first session of ALA-PDT. After 4 sessions of ALA-PDT, the lesion was completely removed and did not recur. Therefore, we consider that ALA-PDT combined with CO2 laser is a safe and effective choice for the treatment of seborrheic keratosis in the auricle.

Abstract
Seborrheic keratosis lesions are tumors that rarely occur in the external auditory canal. There are several histological variants, and one of them is the irritated seborrheic keratosis. This kind has been scarcely reported in the literature. We report a 62 years old man with this lesion that relapses after monopolar electrocautery, and finally is removed by skin flap dissection.

Abstract
Seborrheic keratoses (SKs) are ubiquitous, generally benign skin tumors that exhibit high clinical variability. While age is a known risk factor, the precise roles of UV exposure and immune abnormalities are currently unclear. The underlying mechanisms of this benign disorder are paradoxically driven by oncogenic mutations and may have profound implications for our understanding of the malignant state. Advances in molecular pathogenesis suggest that inhibition of Akt and APP, as well as existing treatments for skin cancer, may have therapeutic potential in SK. Dermoscopic criteria have also become increasingly important to the accurate detection of SK, and other noninvasive diagnostic methods, such as reflectance confocal microscopy and optical coherence tomography, are rapidly developing. Given their ability to mimic malignant tumors, SK cases are often used to train artificial intelligence-based algorithms in the computerized detection of skin disease. These technologies are becoming increasingly accurate and have the potential to significantly augment clinical practice. Current treatment options for SK cause discomfort and can lead to adverse post-treatment effects, especially in skin of color. In light of the discontinuation of ESKATA in late 2019, promising alternatives, such as nitric-zinc and trichloroacetic acid topicals, should be further developed. There is also a need for larger, head-to-head trials of emerging laser therapies to ensure that future treatment standards address diverse patient needs.

Abstract
We compare the results of clinical observation and histopathology analysis for developing a differential diagnosis of seborrheic keratosis (SK) of the external auditory canal (EAC). A 46-year-old man with a history of a recurrent lesion in the EAC underwent clinical observation of the skin lesion's appearance, computed tomography (CT) scan, magnetic resonance imaging (MRI), and several biopsies. Initially, a benign form of SK was diagnosed based on several biopsies performed over a 10-year period. The lesion's appearance was consistent with a malignant disease, which led the clinician to perform a CT scan and an MRI scan. The patient underwent partial petrosectomy to completely remove the lesion as CT and MRI scans showed an infiltrative process. Squamous carcinoma was the final histological diagnosis. The patient was disease free at 1 year of follow-up after petrosectomy. In conclusion, if there are inconsistencies between clinical observation and histological report, additional tests should be performed to exclude the malignity of a lesion.

Abstract
Seborrheic keratosis (SK) is a common, benign, cutaneous skin tumor of the elderly patients. It is commonly observed in the head, neck, trunk, and extremities except the palms and soles. Its occurrence in the auricle has been reported even more rarely than in external auditory canal. We experienced rare SK in the auricle that was completely removed and did not recur.

Abstract
BACKGROUND Seborrheic keratosis (SK) of the outer ear canal is rarely described in literature. Etiological risk factors involved in SK such as exposure to human papillomavirus (HPV) and ultraviolet (UV) light are established but must still be confirmed. In recent years, new insights into the pathogenesis of SKs occurred in the area of molecular pathogenesis. Fibroblast growth factor receptor 3 (FGFR3) gene and p110α subunit of phosphoinositide 3-kinase (PIK3CA) oncogene mutations are known to be involved. METHODS We describe two cases of SK of the outer ear canal. We conducted a review of literature and examined the role of etiological risk factors involved in our cases. The lesions were primarily treated with surgical resection. Postoperatively, in both patients, the lesions recurred after a considerably long disease-free interval. We tested both FGFR3 and PIK3CA genes for mutations, in the primary and recurrent lesions. RESULTS We did not find any mutations in both genes in all samples. CONCLUSION Additional research is needed to further establish possible etiological risk factors and to clarify the involvement of PIK3CA and FGFR3 genes in the pathogenesis of seborrheic keratosis of the outer ear canal. These cases underscore the need for meticulous diagnosis, treatment, and sufficient long-term follow-up.
