  • Basal cell carcinoma(BCC) is malignant epithelial neoplasm arising from either basal cells or pluripotential appendageal cells of the epidermis. BCC is the most common cutaneous malignancy, especially in sun-exposed sites, such as head and neck. But its occurrence on the finger is very rare. We experienced a case of BCC arising on the dorsal surface of the middle finger of a young woman. This case is not associated with any predisposing factors such as basal cell nevus syndrome, trauma, or preexistent dermatosis. Following surgical removal of the lesion, the defect was covered with full-thickness skin graft. The patient has presented no sign of relapse for 1 year of clinical follow-up. We report this rare case of BCC in terms of age and location.

  • Aggressive benign odontogenic neoplasms have substantial potential to grow to an enormous size with resulting bone deformities, and they often invade adjacent tissues and spread beyond their normal clinical and radiographic margins; as such, they have a high rate of recurrence. Historically, management (conservative versus aggressive) on the basis of clinical, radiographic and/or histopathologic characteristics has been controversial. However, recent advances in the understanding of the biological features of these lesions may provide greater evidence of the benefits of conservative management. Three patients with different complaints and final histopathologic diagnoses were enrolled in the study. All three cases were treated by a single operator with similar conservative surgical procedures. During follow-up, the patients had uneventful secondary healing and bone regeneration, less packing time than previously reported, no clinical or radiographic evidence of recurrence and no apparent deformity. The aggressive behavior of these lesions requires long clinical and radiographic follow-up. Conservative surgical management may be an option to reduce recurrence and morbidity and increase the probability of uneventful secondary healing and bone regeneration.

  • Occurrence of multiple cysts in jaw bone is rare compared to solitary cysts. numerous cysts occurring in jaw bone which not accompany any syndromes are defined as multiple jaw cysts, and most of these cases in children are keratocystic odontogenic tumor (KCOT) Multiple KCOT occurring in children are often associated with basal cell nevus syndrome(BCNS), so if multiple cysts are found on the radiograph, we suspect this syndrome and pursue clinical and pathological tests. In this case, a pediatric patient, reporting with multiple cysts in the jaw was suspected of BCNS, but hasn't shown any other symptoms of this syndrome up to date, and has kept repeating surgical operation and recurrence of the tumor. Although no symptoms besides multiple jaw cysts is present, it is often reported that other symptoms appear late in the patient's age. Therefore, in cases where multiple odontogenic tumors are found in children, continuous radiographic and clinical follow-ups in order to check the progress of the syndrome is considered important.

  • Recently, human life is getting longer due to change of living environment and development of medical technology, and silver medical technology has been in the limelight. Geriatric skin disease is difficult to detect early, and when it is missed, it becomes a malignant disease and is difficult to treatment. Melanoma is one of the most common diseases of geriatric skin disease and initially has a similar modality with the nevus. In order to overcome this problem, we attempted to perform a feature analysis in order to attempt automatic detection of melanoma-like lesions. In this paper, one is first order analysis using information of pixels in radiomic feature. The other is a gray-level co-occurrence matrix and a gray level run length matrix, which are feature extraction methods for converting image information into a matrix. The features were extracted through these analyses. And classification is implemented by SVM.

  • Nevoid basal cell carcinoma syndrome (NBCCS) is a rare autosomal genetic disease caused by a PTCH mutation. The disease is characterized by multiple basal cell carcinomas of the skin, multiple keratocystic odontogenic tumors (KCOTs) in the jaw, palmar and/or plantar pits, bifid ribs, ectopic calcification of the falx cerebri, and skeletal abnormalities. Early diagnosis is difficult in many cases because there may be a number of systemic symptoms. The purpose of this study is to report the case of a 12-year-old girl who was hospitalized with multiple KCOTs that occurred in the upper and lower jaws. Through characteristic clinical symptoms and radiologic findings, she was finally diagnosed as having NBCCS. This study also aims to organize the symptoms often observed in Korea using previously published case reports to provide useful information for the early diagnosis of NBCCS.

  • Issues related to the control of seizures and bleeding, as well as behavioral management due to mental retardation, render dental treatment less accessible or impossible for patients with Sturge-Weber syndrome (SWS). A 41-year-old man with SWS visited a dental clinic for rehabilitation of missing dentition. A bilateral port-wine facial nevus and intraoral hemangiomatous swollen lesion of the left maxillary and mandibular gingivae, mucosa, and lips were noted. The patient exhibited extreme anxiety immediately after injection of a local anesthetic and required various dental treatments to be performed over multiple visits. Therefore, full-mouth rehabilitation over two visits with general anesthesia and two visits with target-controlled intravenous infusion of a sedative anesthesia were planned. Despite concerns regarding seizure control, bleeding control, and airway management, no specific complications occurred during the treatments, and the patient was satisfied with the results.

  • Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is characterized by various embryological deformities and carcinoma formation. It is caused by PTCHI gene mutations and is autosomal dominantly inherited. Some of the main symptoms of NBCCS are multiple basal cell carcinomas, multiple keratocystic odontogenic tumors (KCOTs) of the mandible, hyperkeratosis of the palmar and plantar, skeletal deformity, calcification of the falx cerebri, and facial defomity. Recurrent KCOT is the main symptom of NBCCS and is present in approximately 90% of patients. In NBCCS, KCOTs typically occur in multiples. KCOTs can be detected in patients under the age of 10, and new and recurring cysts develop until approximately the age of 30. The postoperation recurrence rate is approximately 60%. This case report presents a 14-year-old female patient with a chief complaint of a cyst found in the maxilla and mandible. The patient was diagnosed with NBCCS, and following treatment of marsupialization and enucleation, the clinical results were satisfactory.

  • Giant congenital melanocytic nevi are very rare, with an estimated incidence of 1 in 20,000 live births. They have a high risk of malignant melanoma transformation and neurological deficits such as neurocutaneous melanocytosis and epilepsy. Early evaluation, surgical intervention and careful long term follow up are recommended to monitor for malignant transformation. We report one case of giant congenital melanocytic nevi diagnosed at birth with the related literatures.

  • Despite the fact that benign skin lesions can undergo malignant transformation, the necessity and timing of the surgical resection have yet to be established. In this study, we analyse three cases of benign-appearing skin lesions, which were found to be carcinomatous on histologic examination and review the literature regarding the importance of prophylactic removal of benign-appearing skin lesion. The first and second cases were female patients wishing for cosmetic surgery. The first patient had a benign-appearing lesion on dorsum nasi, and the second patient had an inconspicuous lesion right along the right nasolabial fold. The third patient was a middle-aged male with a pigmented lesion on the left cheek, who presented to the clinic only after having met the operating surgeon through an acquaintance outside the hospital setting. All of the lesions were suspected to be of benign nature and were excised for cosmesis only. However, histologic examination of these lesions showed that the first two tumors were basal cell carcinoma with the last tumor being squamouse cell carcinoma. Thus, it is considered that removal of benign like skin lesion will result in good prognosis of patients scheduled to undergo other surgery.

  • Basal cell carcinoma (BCC) is the most common skin cancer. Ultraviolet radiation exposure and genetic predisposition are known to be the most important etiological factors. Multiple BCC is often associated with genetic familial conditions such as BCC syndrome, basal cell nevus syndrome. We present a case of 54-year-old female who had multiple BCC that had reoccurred. She was completely cured after receiving radio-chemotherapy for leukemia 16 years ago. She had multiple lesions (scalp, left thigh, right popliteal fossa, and right buttock), and had underwent wide excisions of all lesions. All biopsies revealed BCC. Six years later, she had also multiple lesions; left forehead, frontal vertex scalp, parietal vertex scalp, right occipital scalp, and lower abdomen. We performed wide excision. Histopathological examination revealed BCC. She had no signs of any BCC associated syndrome. We report a rare case of nonsyndromic multiple BCC that reoccurred at the new site.
