“…In a pathologic study by Keene et al on human laryngeal specimens, the overall incidence of chondroradionecrosis was 26 %, although only 3 % were clinically meaningful [4]. Chondroradionecrosis has been showed to be related to total radiation dose, duration of therapy, number of fractions delivered, and field size [5]. Our patient did not have chondroradionecrosis and septal cartilage remained intact during surgery.…”

BackgroundThis report describes the authors’ experience of “melting” septal cartilage after placement of a septal extension graft in a nasopharyngeal cancer patient that had been previously undergone radiation therapy, and provides a review of the literature.MethodsElectronic medical records were used to obtain details of the patient’s clinical history.ResultsA 32-year-old woman, who had previously undergone radiotherapy for nasopharyngeal cancer, visited our department to for rhinoplasty. Rhinoplasty was performed using a septal extension graft to raise the nasal tip (first operation). Five days after surgery, it was found that the septal extension graft was melting without any signs of infection, that is, the graft had softened, lost elasticity, thinned, and partially disappeared without any sign of infection at 5 days, and thus, the nasal tip was reconstructed with conchal cartilage (second operation). Five months after surgery, it was found that almost all septal cartilage had disappeared without any sign of infection, and thus, the entire nasal septum was reconstructed using 2-mm costal cartilage and an onlay graft was used for tip augmentation (third operation).ConclusionsAfter cartilage has been exposed to radiotherapy, its patency should be viewed with suspicion. Further studies are needed for determine the mechanism responsible for cartilage damage after radiotherapy.

“…На долю ПМН приходится более 60% доброкачественных меланоцитарных опухолей [3]. Интрадермальные меланоцитарные невусы (ИМН) представлены гиперпигментированными выступающими куполообразными образованиями с гладкой глобулярной или неровной поверхностью [4]. По особенностям локализации выделяют ИМН Унны (расположенные на шее, туловище или конечностях) и ИМН Мишера (с преимущественной локализацией на лице).…”

Acquired melanocytic nevi in aesthetically significant areas, especially palpebral nevi (PN), are becoming a frequent reason for patients to seek dermatologists. Surgical methods for removal of PN are reported to be associated with the risk of such side effects as scars and loss of eyelashes. Aim of the study. To evaluate the efficacy of the removal of PN on the eyelid area with dual-wavelength radiation of a copper vapor laser (CVL). Patients and methods. Laser removal of medium and large-sized PN (up to 10 mm) was performed in three fair-skin female patients. The procedures were carried out at an average CVL radiation power of 0.60.8 W, at a 3:2 ratio of radiation powers at wavelengths of 511 nm and 578 nm, exposure duration 0.3 s, light spot diameter 1 mm. The treatment was carried out during one session. Results. Removal of PN with dual-wavelength CVL radiation allowed achieving a significant lightening and reduction of the involved area, without scars. The skin healing after the procedure lasted 2 weeks. Conclusion. The high efficacy of the PN removing in the eyelid area using the dual-wavelength CVL radiation allows the introduction of this approach into dermatologists and cosmetologists clinical practice.

Nevi, which consist of nevus cells arising from external auditory canals (EACs) and auricles, are rare and their characteristics are not thoroughly understood. The purpose of this study was to analyze the clinicopathological characteristics of melanocytic nevus (MN) in EACs and auricles. Medical records were reviewed in 35 cases with junctional, compound and intradermal nevi treated in Ajou University Hospital, Korea between 2001 and 2011. Patient demographic, location, shape, and diameter of nevi, and pathologic results were analyzed according to the location, EACs (23 cases) and auricles (12 cases). Female predominance was noted in both EAC (60.9 %, 14 cases) and auricular (75 %, 9 cases) nevi. The mean age of EAC nevi (37.1 years) was younger than that of auricular nevi (42.2 years). The chief complaint was a symptomless mass in both groups, mostly in dome-like gross appearances. The mean diameter of EAC and auricular nevi was 9.6 (3-16) mm and 12.2 (3-25) mm, respectively. Histological findings chiefly presented intradermal nevi in EACs (78.3 %) and auricles (83.3 %) which showed preference to older patients, in contrast to the compound type. All nevi including five cases with skin grafts were completely excised without any recurrence within the follow-up period (average 5.3 months). A possible dysplastic nevus was detected in only one case. All MNs in EACs or auricles reveal similar characteristics. Early and complete excision is recommended to avoid skin graft, functional problems, and the risk of malignant melanoma.

Intradermal melanocytic nevus of the external auditory canal

Abstract: Intradermal nevi are common benign pigmented skin tumors. Their occurrence within the external auditory canal is uncommon. The clinical and pathologic features of an intradermal nevus arising within the external auditory canal are presented, and the literature reviewed.
