This short paper reports the method and the evaluation results of Casio and Shinshu University joint team for the ISBI Challenge 2017 – Skin Lesion Analysis Towards Melanoma Detection – Part 3: Lesion Classification hosted by ISIC. Our online validation score was 0.958 with melanoma classifier AUC 0.924 and seborrheic keratosis classifier AUC 0.993.

Patients with HIV have higher risk of developing squamous cell carcinoma of the skin given the increased risk of HPV infection, which alters cell proliferation and apoptosis [1]. Pigmented Bowen's disease is an uncommon form of squamous cell carcinoma in-situ characterized by pigmented lesions that can clinically mimic superficial spreading melanoma, pigmented basal cell carcinoma, melanocytic ...

In this article, we report a 33-year-old female patient with lesions of bilateral external auditory canals who was treated using fiber CO2 laser without canaloplasty. Histopathological examination confirmed the diagnosis of irritated type seborrheic keratosis, which is rare in external auditory canal. Twelve months after the treatment, the patient showed no signs of recurrence.

Seborrheic keratosis is a benign tumour of external ear originating from proliferative epithelial cells. Its most common site ranges from the retroauricular region to the helical rim. Diagnosis is made on the basis of clinical & histopathological examination. Here, we discuss the clinical presentation, differential diagnosis, pathological diagnosis and management of such a case.

It may be clinically difficult to differentiate early-stage melanoma from benign tumors, specially pigmented seborrheic keratosis. Dermoscopy can help; however, the findings are not always conclusive. Therefore, histopathology may be necessary for a correct diagnosis. We describe a melanocytic lesion with dubious clinic and dermoscopic findings. An incisional biopsy of a suspicious area, guided...

A clinicopathologic study of 31 squamous cell carcinomas of the eyelid was conducted. The tumor was encountered less frequently than in previous reports, due largely to the refinement of the pathologic diagnosis. Eighteen cases originally diagnosed as squamous cell carcinoma were eliminated because the diagnoses were changed to sebaceous gland carcinoma (10), basal cell carcinoma (4), seborrhei...

basal cell carcinoma (bcc) is the most common cancer of the skin. definite diagnosis usually requires histological examination but recently it has been suggested that cytological examination of skin smear can be used as an alternative. to evaluate sensitivity and specificity of cytological examination, a total of 125 skin lesions, clinically suspected to be bcc were studied. cytological samples...

Segmental neurofibromatosis (SNF) is a rare variant of neurofibromatosis (NF) type 1 characterized by a restricted distribution of cafe-au-lait macules, and/or neurofibromas, and rarely freckling to a single dermatomal segment. Patients with NF type 1 have an associated increased risk for benign or malignant tumours. The prevalence of typical NF type 1 complications including malignancies in SN...

Acromegaly is a chronic, insidious and rare disease, caused by hyper secretion of the growth hormone, which metabolic and trophic effects commonly result in cutaneous manifestations, sometimes preceding other clinical symptoms. The authors have assessed 15 patients with acromegaly and found dermatologic lesions in all of them, mainly skin thickening, acrochordons, epidermoid cysts, pseudoacanth...

BACKGROUND Seborrheic keratosis (SK) is one of the most common epidermal tumors of the skin. However, only a few large-scale clinicohistopathological investigations have been conducted on SK or on the possible correlation between histopathological SK subtype and location. OBJECTIVE The aim of this study was to analyze the clinical and histopathological features of a relatively large number of...
