Purpose: Painful plantar callosities under the second, third or fourth metatarsal head have been controverted about its treatment mordalities. We performed the vertical chevron osteotomy in patients with painful callosities on the second and third metatarsal head, and evaluated the outcome clinically. Materials and Methods: Fourteen cases from 10 patients who had plantar keratosis were operated by vertical chevron osteotomy from March 2005 to October 2008. We used K-wire fixation for all cases. We evaluated the clinical results by the patients' satisfaction and disappearance of plantar lesion. Results: The plantar keratosis was completely disappeared in 8 cases and partially in 5 cases. In 2 cases, patients expresses their pain caused by constant metatarsalgia that was suspected to be dorsal incisional pain and joint capsulitis. Transmetatarsalgia was not appeared. Conclusion: We consider vertical chevron osteotomy as a good surgical method for treatment of plantar keratosis.

Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma that commonly occurs in the oral cavity. However, VC of the facial skin is relatively rare. We report a case of a 91-year-old woman with VC of the facial skin in the left zygoma area. She was diagnosed with actinic keratosis (4×3 cm) of the same site approximately 12 years previously, but declined further treatment. The mass was excised with a minimum of 0.4 cm from gross margins with the result of free from tumor of all margins by frozen section, allowing for primary closure after skin undermining. Basal resection was performed in the preplatysmal plane. The diagnosis of VC was confirmed by histopathological examination. Postoperatively, the wound healed without incident and with no signs of facial nerve injury. To our knowledge, this is the first reported case of VC of facial skin arising from actinic keratosis.

본 연구는 에스테틱과 메디컬에서 여드름 치료제로 잘 알려진 글리콜릭산필링과 해초필링, 일반스크럽제를 사용하여 모공각화증 피부에 미치는 영향을 살펴보고 모공각화증 피부 개선 프로그램의 기초 자료로 제시하고자 수행하였다. 실험방법은 실험군인 글리콜릭산필링(GP)군과 해초필링(SP)군, 대조군인 일반스크럽제(GS)군으로 분류하였으며, 모공각화증이 다소 많은 팔과 다리 부위를 각 군별 5부위씩 선정하여 6주간 시행하였다. 피부측정은 실험 전 0주차, 실험 2주차, 실험 4주차, 실험 6주차에 각질량, 유분량, 수분량, 색소침착을 측정하여 실험 전 후를 비교 분석하였다. 분석결과 실험군인 GP군은 실험 후 수분량 증가(t=-4.064, p<0.01)와 색소침착 감소(t=3.536, p<0.01), SP군은 실험 후 각질량의 감소(t=2.370, p<0.05)와 색소침착의 감소(t=4.017, p<0.01) 대조군인 GS군은 각질량의 감소(t=2.834, p<0.05)와 수분량의 증가(t=-7.589, p<0.001)로 유의미한 차이가 있는 것으로 나타났다. 또한 피부 자극 반응 차이에서는 GS군이 가장 자극일 적은 것으로 나타났다. 모공각화증 관리의 개선 만족도는 실험군의 SP군이 만족도가 가장 높은 것으로 나타났다. 동일한 제품으로 관리를 받은 의향에서는 실험군의 SP군과 GP군이 동일하게 높게 나타났으며, 실험군과 대조군 모두 모공각화증의 관리가 필요한 것으로 나타났다. 결론적으로 여드름의 치료제로도 많이 사용되는 해초필링, 글리콜릭산필링, 일반스크럽제는 모공 주변에 쌓인 각질을 제거하여 각질주기를 정상화시키고, 피부의 수분을 증가시켜 모공각화증 피부를 개선시키는 효과가 있음을 알 수 있었다. 따라서 모공각화증 피부 개선을 위해서는 적절한 각질제거와 피부장벽을 보호하는 보습제 사용이 꾸준히 함께 적용되어야 할 것이며, 향후 본 연구가 모공각화증 피부 개선 프로그램의 기초 자료로 사용이 가능할 것으로 사료된다.

Basal cell carcinoma (BCC) comprising several lesions is not uncommon, but nonsyndromic multiple BCCs with parotid invasion are rare entities. We present two cases of multiple sporadic, nonsyndromic BCCs, and one of these cases is a unique case of parotid invasion associated purely with actinic keratosis. In Case 1, a 79-year-old female presented with multiple skin lesions on the face and left hand. All lesions were completely removed by surgery. The pathologic results showed lesions consistent with BCC and some lesions consistent with actinic keratosis. After 8 months, the patient presented with skin lesions in bilateral temporal areas and left cheek area. Surgical excision of the lesions was performed, and the biopsy results were squamous cell carcinoma in situ and actinic keratosis. In Case 2, a 43-year-old woman presented with multiple skin lesions on the face, scalp, right chest, abdomen and right leg. All lesions were completely removed by surgery. Pathologic evaluation confirmed the diagnosis of BCC. BCC is rarely metastatic, but it can lead to severe disfiguration or destruction. It is important to diagnose and treat BCC at an early stage.

Cutaneous horns are conical, circumscribed protuberances formed by densely layered keratin. These lesions originate from basal keratinocytes and may manifest as benign, premalignant, or malignant cutaneous pathology in chronically sun-damaged areas. Complete surgical excision with histologic examination is needed for potential malignancy. In this report, we describe two elderly women presenting with solitary facial cutaneous horns, which were respectively diagnosed as actinic keratosis and squamous cell carcinoma.

The term keratosis covers a variety of growths such as warts and pressure-induced callosities. Warts develop in the absence of pressure, and often clear up again after a certain period, usually without treatment. Clavi can develop as a result of wearing poorly fitting shoes, but also deformed toes or other anatomical deformities affecting the foot. The resulting non-anatomical stressing leads to the formation of pressure callosities and even to pressure sores. It confronts hereupon, it searched the cure against the clavus with fructus mume(烏梅) and it arranged. The possibility of getting the result regarding the clavus treatment with fructus mume(烏梅) from the oriental medicine it was.

Disseminated superficial actinic porokeratosis (DSAP) is a rare keratinization disorder. It is histopathologically characterized by the presence of coronoid lamellae and clinically by lesions showing central atrophy with elevated borders. Squamous cell carcinoma originating in the classical Mibelli subtype of porokeratosis is well-documented; however, few reports have described squamous cell carcinoma in DSAP lesions. We report the case of a 76-year-old woman with DSAP who developed Bowen's disease, actinic keratosis, and keratoacanthoma on her face.

Background: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. Methods: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. Results: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. Conclusions: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.

Heterotopic ossification is the formation of extra-skeletal bone in the muscle and soft tissues, and an osteoma is a benign bone-forming tumor composed of compact or mature trabecular bone limited almost exclusively to the craniofacial bones. This paper reports an extremely rare case of heterotopic ossification mimicking an osteoma that occurred independently at the plantar side of the medial sesamoid bone. The patient was a 46-year-old male with a three-month history of pain and a hard mass on the plantar aspect of the left forefoot sole. After excising the lesion, the patient's symptoms were relieved, and no pain or complications occurred. This paper discusses this exceedingly rare case of heterotopic ossification around the medial sesamoid bone with a review of the relevant literature.

Maintaining the patency of the external auditory canal (EAC) during reconstruction is important because of its physiological role in hearing and immunological protective functions. The curved shape of the EAC presents a challenge when performing a skin graft. One of the key points for a successful skin graft is to ensure compression on the wound bed, and many novel methods, including prefabricated ear molds, have been reported for this purpose. In this study, we present a case of a skin graft performed to reconstruct a skin defect following excision of actinic keratosis in the EAC, using the cover of an ear thermometer probe as a mold for the graft to match the curvature of the EAC. This is an economical and practical method for secure compression dressing of a skin graft in the EAC.
