background: peritoneal tuberculosis accounts 1-2% of all forms of tuberculosis. peritoneal tuberculosis is an important differential diagnosis for ovarian cancer in women with ascites, adnexal mass and elevated cancer antigen 125 (ca125) levels. we report a case of a 32- year -old woman with multiple miliary peritoneal deposits mimicking advanced ovarian carcinoma. case presentation: a 32-year-...

BACKGROUND AND PURPOSE Focal cortical dysplasia (FCD) covers a spectrum of conditions in which the neuropathologic and electroclinic presentations and the surgical outcomes vary. The aim of this study was to identify the MR features of histologic subtypes of FCD that would be useful for differential diagnosis. METHODS We reviewed the MR data of 49 patients treated surgically for intractable p...

Melanoma is the deadliest form of skin cancer. Well-delineated diagnostic histologic criteria for malignancy in melanocytic lesions have been put forth, and are widely accepted. The majority of melanomas can be accurately diagnosed on a sufficient biopsy based on evaluation of these histologic parameters, including asymmetry, lack of circumscription, impaired maturation, hypercellularity, cytol...

BACKGROUND The diagnosis of dermatofibrosarcoma protuberans (DFSP) in childhood is often difficult because of the deceptive appearance of the lesions. Little is known about congenital DFSP, the frequency of which is probably underestimated because the initial lesion may pass unnoticed. OBSERVATIONS We studied 9 DFSP congenital cases (8 plaques and 1 nodule) initially suspected to be benign le...

Yet meningiomas have characteristic neuroimaging features, some other lesions are still confusing with meningiomas. The aim of this study was trying to find the typical (1)H-MRS metabolic factors of histologic subtyped meningiomas, schwannomas, metastases, and other brain tumors for differential diagnosis among them. (1)H-MRS using STEAM (TE/30 ms, TR/2 sec) and PRESS (TE/288 ms, TR/2 sec) sequ...

Nonalcoholic fatty liver disease (NAFLD), defined as abnormal accumulation (> 5%) of hepatic triglyceride without excess alcohol intake, is the most common form of chronic liver disease in adults and children in the United States. NAFLD encompasses a spectrum of histologic findings including uncomplicated steatosis, steatosis with inflammation and steatohepatitis [nonalcoholic steatohepatitis (...

PURPOSE To evaluate the accuracy of sonographic endometrial thickness and hysteroscopic characteristics in predicting malignancy in postmenopausal women undergoing surgical resection of endometrial polyps. METHODS Five hundred twenty-one (521) postmenopausal women undergoing hysteroscopic resection of endometrial polyps between January 1998 and December 2008 were studied. For each value of so...

A case of multifocal adenomatoid tumors (mAT) of the myometrium is presented. The patient, a 49-year-old woman underwent vaginal hysterectomy for severe pelvic pain renitent to medical therapy. Diagnosis was made based on histologic examination and immunohistochemistry (IHC). AT should be considered in the differential diagnosis with leiomyoma in patients with severe pelvic pain and an enlarged...

Systemic lupus erythematosus (SLE) is a multiorgan acquired autoimmune disease. The clinical picture can vary greatly. Lupus nephritis (LN), which affects about 50% of SLE patients, associated with high morbidity and death. While renal histologic alterations are evident in almost all patients SLE, involvement only 40% to 75% those individuals. Because this, some who have on their biopsy may not...

In 100 recent CT-guided brain biopsies, the value of intraoperative histologic examination using frozen section technique was evaluated. In 87 of these cases, the biopsy was performed stereotactically. In the remaining 13 cases, a CT-guided free hand technique was used. Of the 100 biopsies performed, adequate tissue for histopathologic diagnosis was obtained in 97, and in three the biopsy was n...
