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

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.

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)

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.

Neurological Manifestation of Sacral Tumors
Neurosurg Focus 15 (2):Article 1, 2003, Click here to return to Table of Contents Neurological manifestation of sacral tumors MICHAEL PAYER, M.D. Department of Neurosurgery, University Hopital of Geneva, Switzerland An extensive analysis of the existing literature concerning sacral tumors was conducted to characterize their clin- ical manifestations. Although certain specific manifestations can be attributed to some of the tumor types, a more general pattern of clinical presentation of an expansive sacral lesion can be elaborated. Local pain with or without pseudoradicular or radicular radiation is the most frequent initial symptom and is usually followed by the manifesta- tion of a lumbosacral sensorimotor deficit; bladder/bowel and/or sexual dysfunction appear throughout the natural course of disease.

The Role of Cytogenetics and Molecular Diagnostics in the Diagnosis of Soft-Tissue Tumors Julia a Bridge
Modern Pathology (2014) 27, S80–S97 S80 & 2014 USCAP, Inc All rights reserved 0893-3952/14 $32.00 The role of cytogenetics and molecular diagnostics in the diagnosis of soft-tissue tumors Julia A Bridge Department of Pathology and Microbiology, University of Nebraska Medical Center, Omaha, NE, USA Soft-tissue sarcomas are rare, comprising o1% of all cancer diagnoses. Yet the diversity of histological subtypes is impressive with 4100 benign and malignant soft-tissue tumor entities defined. Not infrequently, these neoplasms exhibit overlapping clinicopathologic features posing significant challenges in rendering a definitive diagnosis and optimal therapy. Advances in cytogenetic and molecular science have led to the discovery of genetic events in soft- tissue tumors that have not only enriched our understanding of the underlying biology of these neoplasms but have also proven to be powerful diagnostic adjuncts and/or indicators of molecular targeted therapy. In particular, many soft-tissue tumors are characterized by recurrent chromosomal rearrangements that produce specific gene fusions. For pathologists, identification of these fusions as well as other characteristic mutational alterations aids in precise subclassification. This review will address known recurrent or tumor-specific genetic events in soft-tissue tumors and discuss the molecular approaches commonly used in clinical practice to identify them. Emphasis is placed on the role of molecular pathology in the management of soft-tissue tumors. Familiarity with these genetic events -
Desmoplastic Fibroma
Send Orders of Reprints at [email protected] 40 The Open Orthopaedics Journal, 2013, 7, 40-46 Open Access Desmoplastic Fibroma: A Case Report with Three Years of Clinical and Radiographic Observation and Review of the Literature Alexander Nedopil*, Peter Raab and Maximilian Rudert Department of Orthopaedic Surgery at the University of Würzburg, König Ludwig Haus, Germany Abstract: Background: Desmoplastic fibroma (DF) is an extremely rare locally aggressive bone tumor with an incidence of 0.11% of all primary bone tumors. The typical clinical presentation is pain and swelling above the affected area. The most common sites of involvement are the mandible and the metaphysis of long bones. Histologically and biologically, desmoplastic fibroma mimics extra-abdominal desmoid tumor of soft tissue. Case Presentation and Literature Review: A case of a 27-year old man with DF in the ilium, including the clinical, radiological and histological findings over a 4-year period is presented here. CT scans performed in 3-year intervals prior to surgical intervention were compared with respect to tumor extension and cortical breakthrough. The patient was treated with curettage and grafting based on anatomical considerations. Follow-up CT scans over 18-months are also documented here. Additionally, a review and analysis of 271 cases including the presented case with particular emphasis on imaging patterns in MRI and CT as well as treatment modalities and outcomes are presented. Conclusion: In patients with desmoplastic fibroma, CT is the preferred imaging technique for both the diagnosis of intraosseus tumor extension and assessment of cortical involvement, whereas MRI is favored for the assessment of extraosseus tumor growth and preoperative planning.
