The aim of this study was to analyze the clinical • Benign tumor features of patients who underwent surgery for an EAC mass confirmed as a benign • Surgical excision lesion. • Recurrence • Infection Methods: This retrospective study involved 53 patients with external auditory tumors who received surgical treatment at Korea University, Guro Hospital. Medical records and evaluations over a 10-year period were examined for clinical characteristics and pathologic diagnoses. Results: The most common pathologic diagnoses were nevus (40%), osteoma (13%), and cholesteatoma (13%). Among the five pathologic subgroups based on the origin organ of the tumor, the most prevalent pathologic subgroup was the skin lesion (47%), followed by the epithelial lesion (26%), and the bony lesion (13%). No significant differences were found in recurrence rate, recurrence duration, sex, or affected side between pathologic diagnoses. -
Bone and Soft Tissue Tumors Have Been Treated Separately
EPIDEMIOLOGY z Sarcomas are rare tumors compared to other BONE AND SOFT malignancies: 8,700 new sarcomas in 2001, with TISSUE TUMORS 4,400 deaths. z The incidence of sarcomas is around 3-4/100,000. z Slight male predominance (with some subtypes more common in women). z Majority of soft tissue tumors affect older adults, but important sub-groups occur predominantly or exclusively in children. z Incidence of benign soft tissue tumors not known, but Fabrizio Remotti MD probably outnumber malignant tumors 100:1. BONE AND SOFT TISSUE SOFT TISSUE TUMORS TUMORS z Traditionally bone and soft tissue tumors have been treated separately. z This separation will be maintained in the following presentation. z Soft tissue sarcomas will be treated first and the sarcomas of bone will follow. Nowhere in the picture….. DEFINITION Histological z Soft tissue pathology deals with tumors of the classification connective tissues. of soft tissue z The concept of soft tissue is understood broadly to tumors include non-osseous tumors of extremities, trunk wall, retroperitoneum and mediastinum, and head & neck. z Excluded (with a few exceptions) are organ specific tumors. 1 Histological ETIOLOGY classification of soft tissue tumors tumors z Oncogenic viruses introduce new genomic material in the cell, which encode for oncogenic proteins that disrupt the regulation of cellular proliferation. z Two DNA viruses have been linked to soft tissue sarcomas: – Human herpes virus 8 (HHV8) linked to Kaposi’s sarcoma – Epstein-Barr virus (EBV) linked to subtypes of leiomyosarcoma z In both instances the connection between viral infection and sarcoma is more common in immunosuppressed hosts. -
CASE REPORT Intradermal Nevus of the External Auditory Canal
Int. Adv. Otol. 2009; 5:(3) 401-403 CASE REPORT Intradermal Nevus of the External Auditory Canal: A Case Report Sedat Ozturkcan, Ali Ekber, Riza Dundar, Filiz Gulustan, Demet Etit, Huseyin Katilmis Department of Otorhinolaryngology and Head and Neck Surgery ‹zmir Atatürk Research and Training Hospital, Ministry of Health, ‹ZM‹R-TURKEY (SO, AE, FG, DE, HK) Department of Otorhinolaryngology and Head and Neck Surgery Etimesgut Military Hospital , ANKARA-TURKEY (RD) Intradermal nevus is the most common skin tumor in humans; however, its occurrence in the external auditory canal (EAC) is uncommon. The clinical manifestations of pigmented nevus of the EAC have been reported to include ear fullness, foreign body sensation, hearing impairment, and otalgia, but some cases were asymptomatic and were found incidentally. The treatment of choice for a symptomatic intradermal nevus in the EAC is complete excision. There has been no recurrence reported in the literature . A pedunculated, papillomatous hair-bearing lesion was detected in the external auditory canal of the patient who was on follow-up for pruritus. Clinical and pathologic features of an intradermal nevus of the external auditory canal are presented, and the literature reviewed. Submitted : 14 October 2008 Revised : 01 July 2009 Accepted : 09 July 2009 Intradermal nevus is the most common skin tumor in left external auditory canal. Otomicroscopic humans; however, its occurrence in the external examination revealed a pedunculated, papillomatous auditory canal (EAC) is uncommon [1-4]. Intradermal hair-bearing lesion in the postero-inferior cartilaginous nevus is considered to be a form of benign cutaneous portion of the external auditory canal (Figure 1). -
A Case of Intradermal Melanocytic Nevus with Ossification (Nevus of Nanta)
197 A Case of Intradermal Melanocytic Nevus with Ossification (Nevus of Nanta) Young Bok Lee, M.D., Kyung Ho Lee, M.D., Chul Jong Park, M.D. Department of Dermatology, College of Medicine, The Catholic University of Korea, Seoul, Korea A 49-year-old woman presented with a 30-year history of asymptomatic plaque on her right temple. The histological examination revealed nests of nevus cells throughout the entire dermis. Bony spicules were seen just beneath the nevus cell nests in the lower dermis. Cutaneous ossification is an unusual event. Herein, we present a case of intradermal melanocytic nevus with unusual ossification (nevus of Nanta). To the best of our knowledge, this is the first such case report in the Korean literature.

Craniofacial Chondrosarcomas: Imaging Findings in 15 Untreated Cases
165 Craniofacial Chondrosarcomas: Imaging Findings in 15 Untreated Cases Ya-Yen Lee1 Radiographic findings of 15 untreated chondrosarcomas of the cranial and facial Pamela Van Tassel bones were reviewed. These tumors have a propensity to occur in the wall of a maxillary sinus, at the junction of sphenoid and ethmoid sinuses and vomer, and at the undersur face of the sphenoid bone. Because of its slow-growing nature, chondrosarcomas tend to be large, multi lobulated, and sharply demarcated when detected. Frequent bone changes are a combination of erosion and destruction, with sharp transitional zones and absent periosteal reaction. Tumor matrix calcifications, not necessarily chondroid, are almost always present. Both CT and MR may be necessary for thorough evaluation of tumor extent. Chondrosarcoma, a malignant but usually slow-growing cartilaginous tumor, constitutes approximately 11 % of malignant bone tumors [1] but rarely occurs in the craniofacial region . Because of its propensity to occur in the deep facial structures or base of the skull, the true extent and origin of the tumor may be overlooked if not properly evaluated radiographically. We review a relatively large series of craniofacial chondrosarcomas and discuss the differential diagnosis and choice of imaging technique. Materials and Methods This retrospective radiologic review was based on the pretreatment radiographic studies of 15 patients with craniofacial chondrosarcomas seen at our institution over a period of 40 years , excluding three intracranial dural chondrosarcomas, which are to be reported sepa rately. An attempt was also made to correlate the radiographic findings with the hi stologic grades of the tumors. The ages of the patients ranged from 10 to 73 years , with a mean of 40 years. -
