introduction: the process of discriminating among benign and malignant hyperplasia begun with subjective methods using light microscopy and is now being continued with computerized morphometrical analysis requiring some features. one of the main features called volume percentage of stroma (vps) is obtained by calculating the percentage of stroma texture. currently, this feature is calculated by...

Prostatic intra-epithelial neoplasia (PIN) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. In this study, we applied the PIN grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of...

ectopic cervical thymus (ect) is an essentially benign condition that is identified during the development of the thymus, and is rare among the adult population. thymic hyperplasia is another thymus-associated condition, which is known to occur secondary to hyperthyroidism. a 39-year-old woman with hyperthyroidism presented with an enlarging submandibular mass, which was diagnosed as a benign h...

Background: Endometrial hyperplasia is important clinically, because it can lead to abnormal uterine bleeding (AUB) which itself can precede to endometrial cancer. Endometrial carcinoma is the most common malignancy of the female genital tract, occurring about 75-85% in younger, perimenopousal women as hyperplasic endometrial. The treatment is hysterectomy or hormone therapy with progesterone. ...

background: abnormal uterine bleeding is a common presentation of uterine abnormalities among premenopausal and postmenopausal women. objective: to evaluate and compare the diagnostic accuracy of saline contrast sonohysterography and hysteroscopy for detecting the cause of abnormal uterine bleeding. materials and methods: a total of 65 women with abnormal uterine bleeding were enrolled in this ...

Focal epithelial hyperplasia or Heck’s disease is a benign, rare viral disease of the oral cavity and is associated with human papillomavirus 13 and 32 (HPV-13 and HPV-32). Most patients are children but adults may also be at risk. Clinically, the patients have multiple small white or pink papules on the mucosal surface of the lips, buccal mucosa and the tongue. In Iran, this disease seems to b...

-Canine melanoma has been transplanted to allogeneic neonatal recipients receiving continuous immunosuppression with anti-lymphocyte serum. One spontaneous melanoma was directly transplanted into 8 recipients, 6 of which developed tumours. 5/5 melanoma cell cultures were transplantable, with 19 tumour takes in 31 allogeneic recipients. Serial passage was performed in the case of two melanomas. ...
