adenoid cystic carcinomas are deceptive malignancies that show slow growth and local invasion with recurrences seen many years after diagnosis. upto 50% of these tumors occur in the intraoral minor salivary glands usually in the hard palate. buccal mucosal tumors are relatively rare. we determined the incidence of buccal mucosal adenoid cystic carcinoma by reviewing the number of reported cases...

background and objectives: this study was carried out with the objective of determining the genomic variability of p. aeruginosa strains isolated from patients suffering from cystic fibrosis or from environmental cultures collected from different locations in the unit they admitted. materials and methods: a total of 57 clinical and environmental p. aeruginosa isolates were genotyped by enteroba...

background: echinococcosis or hydatid disease is a zoonotic infection caused by larval (metacestode) stages of cestodes belonging to the genus echinococcus, family taeniidae . we aimed to subclone antigen b gene in pqe-30 plasmid, its expression, and purification. methods: we subcloned hi gene into pqe-30 expression vector. the recombinant vector was transformed into e. coli , m15 and mass cult...

background: the objective of this study was to determine the prevalence of cystic echinococcosis (ce) in qom province, central iran using elisa test. methods: overall, 1564 serum samples (800 males and 764 females) were collected from selected subjects by randomized cluster sampling in 2011-2012. sera were analyzed by elisa test using agb. before sampling, a questionnaire was filled out for eac...

uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. leiomyosarcoma (lms) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. herein, we present a case of lms with unusual macroscopic features. the patient was a 61-year-old woman with lms, which consisted of a large cystic mass (88×136...

Introduction: Papillary thyroid carcinoma (PTC) constitutes 75–85% of all thyroid cancers. PTC usually presents as a subtle, commonly slow-growing, painless thyroid mass or a solitary nodule in the neck. This presentation of a cystic neck lump, without the presence of a thyroid nodule, may imitate the course of a benign disease, thus delaying diagnosis and proper treatment.  Case Report: Thr...

Primary tumors of the pleura present grossly as either diffuse or localized neoplasms. The tumors with a diffuse pattern, known as diffuse pleural mesotheliomas arising from the mesothelial cells lining the pleura, are usually highly malignant and are commonly associated with asbestos exposure. The less common localized tumor, now known as a solitary fibrous tumor of the pleura (SFTP), appears ...

Paratesticular mesotheliomas are very rare tumors. In this paper, we present the management of a 38-year-old male patient with paratesticular malignant mesothelioma who was initially misdiagnosed and treated as recurrent epididymitis. After the final pathology report defining paratesticular mesothelioma during scrotal exploration, he underwent radical orchiectomy and hemiscrotal excision as a c...

ALTHOUGH excellent accounts have been published in recent years of the gross and histological pathology of neoplasms believed to be diffuse malignant mesotheliomas, there remains a scarcity of adequate descriptions of their exfoliative cytology. One purpose of this paper is to help correct this deficiency. Another is to present further evidence that diffuse malignant mesothelioma really exists,...
