Tumor of follicular infundibulum (TFI) is a rare benign cutaneous appendage tumor that does not have characteristic clinical features. It is mainly present in the head, neck, and trunk as a solitary lesion. In particular, TFI typically manifests as a plate-like proliferation with multiple thin epidermal connections comprise of monomorphic cells. TFI do not represent cutaneous characteristics, but have clinical significance because TFI is associated with basal cell carcinoma and Cowden's syndrome. We report a case of TFI in parietal scalp with a review of literatures.

Background: The reconstruction of large full-thickness alar defects requires complex surgical procedures that are usually performed in two stages, with concomitant disadvantages in terms of patient trauma, surgical risk, and cost. This study presents a functional folded nasolabial island flap (FNIF) that can be used to repair large-sized full-thickness alar defects in a straightforward manner. Methods: This retrospective study included seven patients who received a FNIF for a full-thickness alar defect between January 2007 and December 2020. The FNIF is different from the conventional nasolabial flap in that it is folded and twisted to achieve nostril reconstruction with a satisfactory three-dimensional mucosal lining in a single stage. The cosmetic and functional results of FNIF were evaluated by both patients and physicians. Results: The age ranged from 51 to 82 years (mean, 65.6 years). The causes of the defects were squamous cell carcinoma, basal cell carcinoma, and trigeminal trophic syndrome. The nostril lining did not collapse, there was no hypertrophic scarring, and air movement through the nostrils on the flap side was normal. Overall, FNIF produced excellent aesthetic and functional outcomes, with minimal patient discomfort. There were no postoperative complications. Conclusion: Compared with existing reconstruction methods for large full-thickness alar defects, FNIF can easily achieve aesthetic and functional success in a single-stage procedure. It provides satisfactory results for both the patient and the surgeon.

함치성 낭종은 일반적으로 미맹출 치아의 치관을 포함하고 있는 형태로, 치아 법랑질과 이장 상피 사이에 액체가 축적되어 생긴 잔존 법랑 상피조직의 퇴행성 변화로 부터 생긴다. 치근단 낭 다음으로 가장 흔한 치성 낭종으로, 주로 단독으로 발생하고 하악 제 3대구치와 상악 소구치에 호발한다. 악골의 다발성 낭종은 주로 기저세포 모반 증후군과 관련된 치성 각화낭이 대부분이고, 점액다당류증 또는 쇄골두개 이형성증과도 관련이 있을 수 있다. 단발성의 함치성 낭종은 우리에게 친숙할 정도로 유병율에서 치료 및 예후까지 잘 알려져 있으나, 전신병력이 없는 다발성의 함치성 낭종은 드물며, 상악과 하악에 발생한 다발성 낭종은 특히 더 드물다. 본 증례는 편측성으로 양악에 함께 발생한 다발성의 함치성 낭종을 가진 11세 소년에 대한 치료 증례로 1년간의 관찰 후 양호할만한 결과를 얻었기에 보고하는 바이다. 1년이라는 관찰 기간이 짧기 때문에 향후 지속적인 임상적, 방사선적 관찰을 필요로 하리라 사료된다.

Objectives: The best treatment for the malignant parotid tumor still remains to be defined, and a better knowledge about the tumor features that predict the treatment result is needed. The aim of this study is to evaluate the treatment outcomes and to suggest the optimal treatment modality for the parotid cancer. Materials and Methods: The clinicopathologic characteristics of 113 patients who were treated for parotid cancer from January 1990 to December 2002 were retrospectively analysed. Univalate analyses were performed to establish the prognostic influence of pateint age, gender, tumor size, histologic grade and lymph node metastasis. Results: The mean age was 46.4 years old (15-81 years) and. The male to female ratio was 1 : 1.1. The chief complaint was a palpable mass in 85%, pain was in 12.4% and facial nerve palsy was accompanied with 2.7%. The mean tumor size was 3.5cm in diameter. The most common malignant tumor was mucoepidermoid carcinoma (33.6%), followed by acinic cell carcinoma (15%), adenoid cystic carcinoma (11%), carcinoma expleomorhpic adenoma (11%), basal cell carcinoma (7%). The most common operative procedure was total parotidectomy (47.8%) and various types of cervical lymph node dissection were added in 69.9%. Postoperative radiotherapy was done in 61.1 %. Postoperative complications developed in 54 cases (47.8%), including 46 cases (40.7%) of facial nerve palsy and 9 cases (8%) of Frey's syndrome. Recurrences developed in 21 cases (18.6%) and deaths in 15 (13.3%). Cumulative survival at 5 year was 75.4%. Univariate analysis of clinical factors showed that histologic grade and positive cervical lymph node significantly influenced survival (p<0.05). Conclusion: These results suggests that the radical resection with lymph node dissection and postopertaive XRT would be necessary to improve the survival of the patients with high grade cancer or positive lymphnode metastasis.

본인은 본교실에서 치험한 악골내 발생된 각화성 낭종들중 다발성인 경우에 이상의 증례에서 동반된 이상소견을 의도적으로 조사해 봄으로써, 악골계를 담당하는 의사로서 악골내에서 다발성 낭종이 발견될 때 NBCCS을 간과해서는 안됨을 느끼게 된다. 또한 이상의 증례에서는 확연한 가족력을 찾아볼 수는 없었으나 이 증후군 자체가 상염색체 우성유전으로 인자전달이 잘 되는 것이므로 세심한 주의와 계속적인 관찰이 요하리라 생각된다.

Objectives: A keratocystic odontogenic tumor (KOT) is a type of odontogenic tumor that mainly occurs in the posterior mandible. Most KOTs appear as solitary lesions; however, they sometimes occur as multiple cysts. This study analyzed the clinical features of multiple KOTs. Materials and Methods: The participants were diagnosed with KOT by biopsy with multiple surgical sites, and were patients at the Pusan National University Hospital and the Pusan National University Dental Hospital from January 1, 2005 to March 31, 2016. Charts, records, images and other findings were reviewed. Results: A total of 31 operations were conducted in 17 patients. The mean patient age was $28.4{\pm}20.1years$. Multiple KOTs were found to occur at a young age (P<0.01). The predominant sites were in the posterior mandible (28.6%). Most cases of multiple lesions appeared in both the upper and lower jaw, and 40.3% of lesions were associated with unerupted and impacted teeth. The overall recurrence rate measured by operation site was 10.4% (8/77 sites). No patients were associated with nevoid basal cell carcinoma syndrome. Conclusion: The pure recurrence rate was lower than estimated, but there was a higher possibility of secondary lesions regardless of the previous operation site; therefore, long-term follow-up is necessary.
