Touch imprint cytology of prostate core needle biopsy specimens: A useful method for immediate reporting of prostate cancer

Background: Cytology plays an important role in the preoperative assessment of many cancers. It is used as a first-line pathological investigation in both screening and diagnostic purposes. Aims: To determine the diagnostic value and accuracy of touch imprint cytology (TIC) smear of prostate core needle biopsy (CNB) specimens in the diagnosis of prostate carcinoma. Materials and Methods: One hundred and twenty-one patients had ultrasound-guided transrectal prostate CNB. A total of 1210 TIC smears were prepared from all CNB specimens. Results: Diagnoses of 1210 TIC smears were compared with the histopathological findings of the CNB specimens. One hundred and seventy (14%) TIC smears were found positive for malignancy, 35 (2.9%) were diagnosed as suspicious for malignancy and 1005 (83.1%) were found negative for malignancy. Twenty-five of 35 suspicious imprints and 150 of 170 malignant smears were confirmed to be malignant on histopathological evaluation. Although 20 malignant TIC smears were defined as benign in standard histological preparations, 10 of them had definitive diagnosis of malignancy following extensive serial sectioning. Last of all, there were 10 false-positive cytology results. Moreover, 10 of the 35 suspected TIC smears were false negative when compared with the histopathological diagnosis. The sensitivity, specificity, positive predictive value and negative predictive value of touch imprint smear results were 100%, 98%, 90.2% and 100%, respectively. Conclusions: TIC smears can provide an immediate and reliable cytological diagnosis of prostate carcinoma. It may clearly help the rapid detection of carcinoma, particularly in highly suspected cases that had negative routine biopsy results for malignancy with abnormal serum prostate specific antigen (PSA) levels and atypical digital rectal examination.

An unusual presentation of a submucous leiomyoma accounting to a non-puerperal uterine inversion: A case report.

Non-puerperal uterine inversion is an extremely rare gynaecological event that is usually associated with uterine tumours such as submucous or cervical leiomyomas. In this report, we describe a case of uterine inversion due to a large submucous leiomyoma in a 42-year-old multiparous and obese Caucasian woman.

Effects of Combination Therapy with Captopril and Angiotensin II on the Viability of Random-pattern Skin Flaps in Diabetic Rat Model

Amaç: Diabetes mellitus, eritrosit agregasyonuna ve endotel disfonksiyonuna yol açarak doku kanlanmasını olumsuz etkiler ve doku hasarının oluşmasını sağlar. Bu mekanizma ile ciltte diabetik yaraların ortaya çıkmasına neden olur. Diabetik yara tedavisinde deri flepleri sıklıkla kullanıldığı halde deri flebinde yeterli kan dolaşımının sağlanması, kan şekerinin düşürülmesi ile birlikte tedavinin başarısında en önemli unsur olarak görülmektedir. Bu çalışmada, deneysel yolla diabet oluşturulan sıçanlarda deri flebinin canlılığını koruyabilmek amacıyla, doku kanlanmasını artırdığı gösterilen captopril ve anjiotensin II’nin etkinliği araştırılmıştır.

CDX2 immunostaining in primary and metastatic germ cell tumours of the testis

Objective To evaluate the immunohistochemical staining pattern of caudal type homeobox 2 (CDX2) protein in germ cell tumours (GCTs) of the testis. Methods This study reassessed archival tissue samples collected from patients diagnosed with primary and metastatic testicular GCTs for CDX2 immunoreactivity using standard immunohistochemical techniques. Positive nuclear immunostaining was evaluated with regard to both the staining intensity and the extent of the staining. Results Tissue sections from primary and metastatic testicular GCTs (n = 104), germ cell neoplasia in situ (GCNis) (n = 5) and benign testicles (n = 15) were analysed. The GCNis and benign testicular tissues showed no immunoreactivity for CDX2. Strong and diffuse staining of CDX2 was demonstrated only in the mature colonic epithelium of teratomas in both primary and metastatic GCTs. CDX2 positivity in other tumours (one pure yolk sac tumour, one yolk sac component of a mixed GCT and one pure seminoma) was infrequent, and was only weak and focal. Conclusions CDX2 immunostaining should be interpreted based on both the staining intensity and the extent of staining so as not to cause misdiagnosis. Teratomas with colonic-type epithelium should be considered in the differential diagnosis if a metastatic tumour with an unknown primary shows prominent CDX2 immunostaining.

Cutaneous Fistulization of an Ovarian Mature Cystic Teratoma: An Unusual Occurrence.

A bilobulated mature cystic teratoma (MCT) at the left ovary measuring 6 cm in diameter fistulized to the left lower quadrant of the anterior abdominal wall, contralateral to McBurneys point. This is the first reported case of a MCT fistulized to the skin. Symptoms, if present, usually depend on the size of the teratoma. However, most patients with a MCT are asymptomatic. Complications such as rupture of the cyst capsule are quite rare. Moreover, complication of fistulization is highly infrequent.
