Relation between actinomycosis and histopathological and clinical features of the palatine tonsils: an Iranian experience

Actinomycosis of the tonsils has been reported in a variable percentage of tonsil specimens by other authors. This study determines the incidence of actinomyces in the palatine tonsil and evaluates the clinical diagnoses and histopathological features of tonsillectomy specimens. In a retrospective study, 204 patients who had undergone tonsillectomy for recurrent tonsillitis [group A] and for sleep apnea without a history of recurrent tonsillitis [group B] were enrolled. The prevalence rate was significantly higher in the adult compared with the pediatric population. The prevalence of tonsillar actinomycetes colonization was higher in patients who had undergone tonsillectomy for recurrent tonsillitis [43.9%] than in patients who had undergone tonsillectomy for obstructive sleep apnea [26.3%]. The prevalence did not differ by sex of patient. Histopathological analysis of resected tonsils did not show active tissue infection. There was a statistically significant relationship between the presence of actinomycosis and age, with a greater occurrence of actinomycosis in adult patients. Although actinomyces colonization is more prevalent in patients with recurrent tonsillitis than sleepdisordered breathing, but the presence of actinomyces does not indicate any active disease

Nevoid basal cell carcinoma [gorlin] syndrome [case report]

A16 year old boy was admitted to the hospital because of a swelling on the left side of mandible .He had multiple small indurated pearly papules on the head and neck with multiple well circumscribed radiolucent cystic space in mandible on panoramic radiography and CT-scan. Histopathologic studies of mandibular cyst and skin lesions revealed the finding in favor of nevoid basal cell carcinoma syndrome [NBCCS]

Benign ostroblastoma of the temporal bone

We have described a benign osteoblastic lesion in the right temporal bone in a 26 year-old girl who presented with a swell mass on the right supra-auricular area and tinnitus of 17 years duration. She had been operated conservatively through middle cranial fossa approach 17 years ago. After that time the patient has had no problem. There was no other developed neurologic deficit or evidence of malignant change throughout the 17 years. When we compared serial CT scans [the old and new films], there was no important difference between them. During a 17-year follow up period, no progression of the tumor was detected. Conservative treatment for such cases is suggested

Comparison of adenoidectomy and myringotomy with and without tube placement in the short term hearing status of children with otitis media with effusion: a preliminary report

Otitis media with effusion [OME] is the most frequent indication for surgery in children. Some surgeons prefer to use adenoidectomy and myringotomy with tympanostomy tubes insertion to prevent the sequelae of the disease and also more improvement of hearing. The aim of this study is to compare adenoidectomy-myringotomy with adenoidectomy-myringotomy plus tympanostomy tube in the management of OME. Thirty children with OME [age range 4-8 year] were randomly assigned to receive adenoidectomy with myringotomy in one ear or adenoidectomy, myringotomy plus tympanostomy tube insertion in the other. The patients were subjected to auditory examinations 1 and 6 months post operation to evaluate hearing levels. The results showed no significant difference in hearing level improvement between these two methods of surgery. It is concluded that adenoidectomy with myringotomy is sufficient for management of otitis media with effusion in children in short term

Apocrine hidrocystoma in external auditory canal

The present report describes clinical, radiographic, and pathological features of an external auditory canal giant apocrine hidrocystoma in a 36-year-old Iranian woman. To the best of our knowledge, this tumor has not previously been reported in this area. There was no evidence of local recurrence one year after surgery

Paraganglioma with radiographic dye: an interesting histopatholological finding

Extraadrenal paraganglioma makes up a dispersed neuroendocrine system which extends from the base of the skull down to the pelvic floor. Paraganglioma have been found in particularly every site in which normal paraganglia are known to occur. Herein, we present a typical case of carotid body paraganglioma according to both histological and immunohistochemical findings. The presence of a large ribbon-like amphophilic to basophilic amorphous material which, according to the history of angiography, must result from the precipitation of angiographic dye makes this entity unique and the first to be reported
