Purpose: Basal cell carcinoma is one of the most common cancers in the western population and the annual incidence rate is still on an increasing course. In Asian countries such as Korea, the incidence of basal cell carcinoma is reported to be remarkably low but is estimated to be in a steep increase nowadays. This study was to analyze the recent clinical trends of basal cell carcinoma in Korea by reviewing a single institution's experience. Methods: Throughout an 11-year period, the surgical excision of 143 cases of basal cell carcinoma was performed in our department. General data of these cases such as the primary site of cancer, age and sex of the patient, operative methods, recurrence rate were reviewed retrospectively. Results: Among the 143 patients included in this study, 82 patients were men and 61 patients were women. The ages ranged from 27 to 89 years with a mean age of 64.0 years. The head and neck region was the most frequently involved primary site for the cancer as 95.1% of the total cases occurred in this area. Especially the nose and perinasal area were the most frequent region, which was followed by the periorbital area, cheek, and perioral area. During this study period, 9 cases showed recurrence of the cancer as the overall recurrence rate was 6.3%. Conclusion: Gradual increase in the incidence of basal cell carcinoma was demonstrated in this study. Basal cell carcinoma showed high incidence in the old-age population as 68.5% of the total patients were more than 60 years of age. High recurrence rate was noted in the nasal region especially after local flap reconstruction. A more cautious approach is to be required when handing such high risk lesions. Multiple factors such as extended life span, increased outdoor leisure activity and exposure to sunlight, higher accessibility to medical services and increased understanding of the public about skin cancer are assumed to be the main reasons for this increase of basal cell carcinoma.

The most common forms of nonmelanocytic skin cancer (NMSC) are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The growing incidence of skin cancer in the Republic of Korea has sparked increasing scientific interest in these types of tumors. In the case described herein, multiple NMSCs occurred asynchronously in various areas of the body in a single patient. A 67-year-old man presented with an ulcerative lesion on the right retro-auricle and multiple keratinized masses on the back and face. The right retro-auricular lesion was diagnosed as BCC, and the keratinized masses on the patient's back and face were diagnosed as SCC. He subsequently presented with numerous pigmented skin lesions on the forehead, temple, pre-auricle, neck, right forearm, right hand, and both thighs. One lesion on the neck was diagnosed as BCC, and five lesions on the right hand and forearm were diagnosed as SCC. The patient was also diagnosed with supraglottic SCC and external auditory canal SCC. An otolaryngologist performed radical excision of the primary SCC. Suspected skin cancer lesions observed on the face and both ears were diagnosed as SCC. Patients with multiple NMSCs are at an elevated risk for additional skin cancers, making periodic follow-up important; furthermore, all suspicious lesions should be biopsied.

Nevoid basal cell carcinoma syndrome(NBCCS) is a autosomal dominant disorder, and its major manifestations are multiple basal cell carcinoma, keratocystic odontogenic tumor, rib anomalies, palmer and plantar pits, calcification of the falx cerebri. Keratocystic odontogenic tumor(KCOT) is defined as intraosseous tumor of odontogenic origin with a characteristic lining of parakeratinized stratified squamous epithelium and potential aggressive behavior. We report a case of a 3-year-old patient with nevoid basal cell carcinoma syndrome who initially presented with unilocular keratocystic odontogenic tumor in maxillary canine region. Keratocystic odontogenic tumor was treated by enucleation, and periodic follow-up check will be required for early diagnosis of additional diseases related with this syndrome.

Multiple odontogenic keratocysts (OKC) are a distinguishing feature of nevoid basal cell carcinoma syndrome (NBCCS). Owing to the high recurrence rate of syndromes associated OKCs, complete surgical resection is generally recommended as a definitive treatment. Herein, we report the management of multiple OKCs with marsupialization followed by excision with peripheral ostectomy in an NBCCS patient. We then discuss lesion progression over 11 years of annual follow-ups.

Porocarcinoma (PC) and basal cell carcinoma (BCC) are distinct skin cancers. Few studies have documented the occurrence of two concurrent types of skin cancers, and to the best of our knowledge, this represents the inaugural report of such a coexisting lesion arising from a capillary malformation. Herein, we report a case of concurrent PC and BCC presenting with capillary malformation. A 93-year-old woman visited our hospital with a protruding mass in her right nasal ala that appeared as a capillary malformation. A biopsy was performed on the skin lesion, and BCC was diagnosed. A wide excision was performed. Permanent biopsy revealed that the skin lesion was a PC with basal cells and squamous differentiation. The safety margin of the deep tissue margin was < 0.1 cm; however, considering the advanced age of the patient, further excision was deemed to not possess any benefits. This case illustrates the importance of recognizing the possibility of multiple skin cancers, even in patients with benign lesions such as capillary malformations. The rarity of this presentation highlights the importance of thorough investigation and histopathological examination of skin lesions in guiding appropriate surgical excision.

Nevoid basal cell carcinoma syndrome is an ecto-mesodermal polydysplasia with numerous manifestations that affect multiple organs. The syndrome is an autosomal dominant inherited, with a high penetration and visible expression. The syndrome is characterized by a series of associated anomalies such as cutaneous, dentofacial, skeletal, ophthalmologic, neurological, and genital anomalies. Generally, the jaw cysts are multiple odontogenic keratocysts, affecting any area of maxilla and mandible. Multiple odontogenic keratocysts of this syndrome are more recurrent than the keratocysts of non-syndrome, thus they are treated aggressively for complete removal. We report a case of multiple jaw cysts associated with nevoid basal cell carcinoma syndrome. In clinical and radiological examinations, frontal bossing, hypertelorism, mild mental retardation and two odontogenic keratocysts in both the maxilla and mandible were observed. Two cysts were treated by marsupialization. For the management of eruption of unerupted teeth, periodic recall check and orthodontic treatment are required.

Background: Cases of simultaneous multiple skin cancers in a single patient have become more common. Due to the multiplicity of lesions, reconstruction in such cases is more difficult than after a single lesion is removed. This study presents a series of patients with multiple facial skin cancers, with an analysis of the surgical removal, reconstruction process, and the results observed during follow-up. Methods: We reviewed 12 patients diagnosed with multiple skin cancers on the face between November 2004 and March 2016. The patients' medical records were retrospectively reviewed to identify the type of skin cancer, the site of onset, methods of surgical removal and reconstruction, complications, and recurrence during follow-up. Results: Nine patients had a single type of cancer occurring as multiple lesions, while three patients had different skin cancer types that occurred together. A total of 30 cancer sites were observed in the 12 patients. The most common cancer site was the nose. Thirteen defects were reconstructed with a flap, while 18 were reconstructed with skin grafting. The only complication was one case of recurrence of basal cell carcinoma. Conclusion: Multiple skin cancers are removed by performing Mohs micrographic surgery or wide excision, resulting in multiple defect sites. The authors emphasize the importance of thoroughly evaluating local lesions surrounding the initially-identified lesions or on other sites when reconstructing a large defect which can not be covered by primary closure. Furthermore, satisfactory results can be obtained by using various methods simultaneously regarding the condition of individual patients, the defect site and size, and the surgeon's preference.

Basal cell nevus syndrome is a rare inherited disorder characterized by mulitple cutaneous basal cell carcinoma, pits of the palms and soles, cysts of the jaws, skeletal abnormalities and ectopic calcifications. Currently there are new lines of investigation based on biomolecular studies, which aim at identifying the molecules responsible for these cysts and thus early allowing an early diagnosis of these patients. We report a case of a 9-year-old boy with the various manifestation of basal cell nevus syndrome, which are multiple odontogenic keratocysts, pits of the soles, bifid ribs, ectopic calcification, macrocephaly, and hypertelorism, etc. Total five odontogenic keratocysts were found. For the reduction of the size of the odon-togenic keratocysts, following preoperative marsupialization, there were surgically enucleated. And the impacted upper right lateral incisor and canine are tracted orthodontically.
