Does asymptomatic inflammation increase PSA? A histopathological study comparing benign and malignant tissue biopsy specimens.

AIM: To determine the effect of inflammation on postage-specific antigen (PSA) levels in patients who were performed transrectal ultrasonography (TRUSG) guided prostate biopsy because of high PSA levels. MATERIALS AND METHOD: 376 tissue specimens of 47 patients with BPH and 176 tissue specimens of 22 patients with prostate adenocancer were analysed histopathologically. Digital rectal examination, TRUSG, and PSA measurements were performed to all the patients before biopsy. Sextant biopsy was performed. Two pathologists examined all the biopsy specimens in blinded fashion. Inflammation pattern was categorized as glandular, periglandular, stromal and perivascular and intensity of inflammation graded from 1 to 3. RESULTS: The mean age of the patients was 66.2 years. The mean serum PSA level of the initial biopsy was 8.7 ng/ml in the BPH and 13.4 ng/ml in the prostate Ca. No relation was found between the serum total PSA levels and prostate volume or patient's age in BPH patients (P = 0.258). In BPH patients stromal, periglandular, glandular inflammations did not increase PSA levels. Perivascular inflammation increased PSA levels significantly. CONCLUSION: The inflammation in perivascular field increases serum PSA levels (P = 0.007). Although high serum PSA levels shows correlation with cancer in biopsy, there is no such significant relation with rebiopsy results and PSA levels at last studies. Because of this, these patients' biopsy samples must be reinspected for infection findings and atipic biopsy or high grade PIN. The result of our study showed that histological perivascular infection within the prostatic gland is a significant factor to serum PSA levels in BPH. If you have negative biopsy sample, pathology must indicate the place of the infection. Follow up of this patient and rebiopsy time are decided according to the result of this negative biopsy sample.

Malignant eccrine poroma in an unusual location.

Malignant eccrine poroma is a rare skin appendage tumour, originating from the intraepidermal and upper dermal eccrine ducts. The tumour either arises spontaneously or develops in a long-standing eccrine poroma, generally in elderly people over 60. Clinically, it tends to be a localized lesion, which manifests itself as a nodule or ulcerated tumour, favouring extremities. We report an 83-year-old female with an enlarging and bleeding tumour on her lumbosacral region. This lesion first appeared as a small pigmented papule and progressed to an erythematous patch with central papular portion and some peripheral pigmentation. Histopathology revealed malignant eccrine poroma. Also, immunohistochemically, diffuse and intense p53 staining was observed. Regular pigment pattern, brown globules and black dots were seen in dermoscopic examination. After performing a wide excision, 20 months of follow-up revealed no recurrence or metastasis of the tumour. This case represents an unusually located malignant eccrine poroma with some pigmentation.

Recidivans cutaneous leishmaniasis unresponsive to liposomal amphotericin B (AmBisome).

A 60-year-old woman with thick crusted erythematous plaques on her glabella, apex nasi and left infraorbital region was diagnosed as recidivans cutaneous leishmaniasis. The lesions were resistant to antimonial drugs. Although some response was observed on the infraorbital region, lesions on the glabella and nose continued to infiltrate despite therapy with liposomal amphotericin B.

Granulomatous hepatitis following intravesical bacillus Calmette-Guerin therapy.

Although intravesical bacillus Calmette-Guerin (BCG) administration is an effective method in the treatment of superficial urinary bladder carcinoma, some complications may arise such as a granulomatous reaction either in the urinary tract or, in rare cases, outside the urinary tract. We report in this paper a case of granulomatous hepatitis following intravesical BCG administration.

The effects of extensive vas mobilization on testicular histology during orchiopexy.

We were aware that extensive mobilization of vas deferens during orchiopexy could cause secondary infertility due to testicular damage and/or functional obstruction of the vas deferens. We decided to perform this experimental study in order to document the effects of this procedure on the testis. Thirty adult fertility-proven New Zealand white rabbits were randomly divided into 3 groups. Ten rabbits underwent extensive mobilization of the vas deferens and the other 10 rabbits had vasectomy on the left side. The remaining 10 rabbits were explored on the left side only and were considered sham controls. Four weeks later all rabbits underwent bilateral orchiectomy. Mean seminiferous tubular diameters and Johnsen's testicular biopsy scores were noted. Comparison of the three groups showed that vas mobilization and vasectomies cause no effect on the viability of testis, however, significant testicular histological changes, which were different from the controls and contralateral testis, were observed. We concluded that during any surgical intervention involving the inguinal canal, vascular and neural supports of the vas deferens should be preserved as much as possible in order to avoid iatrogenic damages to the testis.
