  • The diagnostic accuracy of routine cytological preparations from effusions ranges from 60% to 70%. Immunohistochemical markers, especially tumor-associated antigens, have been successfully employed to increase diagnostic sensitivity in effusion cytology. However, more than two different antibodies in diagnosis of effusions are needed. In the view of prevalence of abnormalities of p53 gene in human malignancies we investigated the diagnostic usefulness of demonstration of p53 protein immunoreactivity in distinguishing benign changes versus malignant processes in effusions. p53 protein expression was studied immunohistochemically in 76 effusions(28 malignant and 48 benign) using anti-human p53 antibody p53 immunoreactivity was identified in 19 of 28(67.9%) malignant effusions. In contrast, no p53 immunoreactivity was observed in all benign effusions. A specificity of 100% and a sensitivity of 67.9% were observed. These results suggest that immunohistochemical detection of p53 protein seems to be helpful in distinguishing benign changes versus malignant processes in effusions, although its principal limitation is its relatively low sensitivity.

  • Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. 1,2) Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. 3) Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion 4) and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.

  • Proteinuria is common in pediatric and adolescent patients. Proteinuria is defined as urinary protein excretion at levels higher than $100-150mg/m^2/day$ in children. It can be indicative of normal or benign conditions as well as numerous types of severe underlying renal or systemic disease. The school urine screening program has been conducted in Korea since 1998. Since then, numerous patients with normal or benign proteinuria as well as early stage renal diseases have been referred to the hospital. Benign proteinuria includes orthostatic proteinuria and transient proteinuria. Most causes of proteinuria can be categorized into 3 types: 1) overflow, 2) tubular, and 3) glomerular. Although treatment should be directed at the underlying cause of the proteinuria, prompt evaluation, diagnosis, and long-term monitoring of these pediatric patients can prevent potential progression of the underlying disease process. This article provides an overview of proteinuria: its causes, methods of assessment, and algorithmic suggestions to differentiate benign from pathologic renal disease.

  • A retrospective study of 21 cases of chest wall tumors, 12 benign and 9 malignant, was carried out to review their clinical radiological and pathological features. On age distribution, most cases [80.9%] were found in 4th to 6th decades. The sex ration [M:F] was represented as 2.5:1. Of the 21 lesions, there were 8 cases of soft tissue tumors, 4 cases of bone and cartilage origined tumors and 9 malignant tumors which included 3 metastatic tumors. The overall mortality was 22.2% and all of the deaths were found in the malignant tumors. All of the patients with benign tumors were treated by excision without recurrence. Distinction between benign and malignant chest wall tumors was not possible using radiographic criteria unless cortical destruction and involvement of soft tissue were visualized. On the basis of our analysis, we believe that all tumors of chest wall should be considered malignant until proven otherwise and that wide excision should be carried out. This is necessary not only to obtain as adequate diagnosis but also to provide the best chance for cure in both benign and malignant lesions.

  • Benign symmetric lipomatosis is a rare disease. Its main characteristic is the symmetric massive deposits of adipose tissue, in unencapsulated form, predominatly on the neck, shoulder, back and upper exterimities. We report a case of a 61 year old man with benign symmetric lipomatosis. He had a history of alcoholic liver cirrhosis. Due to cosmetic defomity, he wanted surgical treatment . We did a cervical lipectomy. He was satisfied with the result, and there was no evidence of recurrence.

  • Benign fibrous histiocytoma (FH) is a benign tumor composed of fibroblasts and histiocytes in varying proportions. This tumor is usually found in adult extremities but rarely occurs in deep soft tissues of the oral cavity. As it is difficult to diagnose with physical and radiologic exams, deep benign FH can only be diagnosed by histopathology. We report a case of a 36-year-old female patient who came to our department with painless swelling in the right buccal mucosa. This case report reviews the clinical, radiological, and histological aspects of this tumor.

  • Hemangioma and vascular malformation is a common vascular benign lesion in the head and neck region. The lesion is a congenital malformation observed in neonates. The treatment this lesion includes surgical excision, cryotherapy, selective embolization and treatment with sclerotic agents. We present three cases of benign oral vascular lesions treated with an intralesional injection of sodium tetradecyl sulfate. The lesions virtually disappeared after three sessions of sclerotherapy, leaving an inconspicuous scar. No side effects were observed. Sclerotherapy with sodium tetradecyl sulfate is effective in treating benign oral vascular lesions, and the use of the sodium tetradecyl sulfate provides alternative or support for surgical methods.

  • There are no standard consensus about treatment results and prognostic factors based on randomized trials for benign vocal fold lesion. Currently, voice therapy is the treatment of choice for vocal nodules, and laryngomicroscopic surgery is for vocal polyps. There are no strong evidences to support it, based on randomized controlled trials, But, it's just a consensus among laryngologist. Considering the pathophysiology of benign vocal cord lesions, cognitive behavioral therapy that corrects the patient's bad voice habits and improves their vocal hygiene could be most important factor for treatment outcomes.

  • Benign salivary gland tumors have relatively lower incidence, but it have various histopathologic diagnosis and biological behavior. Authors analyzed retrospectively 77 patients with benign salivary gland tumor who were treated surgically and had the following results. The most frequent age group was 5th decade, and sex distribution was not specific. The most common location was parotid gland(75.3%) and submandibular gland(20.8%) was next. Histopathologically, the most common salivary gland tumor was pleomorphic adenoma(82.7%) and Warthin's tumor(8.6%) was next. An asymptomatic mass was the most common presentation. Duration of symptoms and signs were mostly under the 5years(90.9%). Diameter of tumors was mostly under 4cm(76.7%). Parotid gland tumors were treated mostly with superficial parotidectomy and submandibular gland tumors were treated mostly with submandibular gland resection. The most common complication was facial nerve palsy(9 cases).

  • Benign fibrous histiocytoma (BFH) is a rare benign primary skeletal tumor that occurs commonly in the long bones, spine and pelvis. BFH constitutes a diagnostic challenge because it shares clinical background, radiological characteristics, and histological features with other fibrous lesions such as non-ossifying fibroma, giant cell tumor. We present a case of BFH with cystic change that occurred in the distal femur. We did not identify any case of BFH with cystic change involving the majority of the lesion that occurred in the metaepiphysis of the long bone.
