Necrosis zone depth after bipolar plasma vaporization and resection in the human prostate.

Objectives: To compare the depth of thermal necrosis after use of bipolar resection and vaporization technique comparing intra-individually bipolar loop and bipolar button electrodes.

Methods: Transurethral resection and vaporization of the prostate was performed in 55 male patients (260 specimens in total). In a standardized procedure, a bipolar resection loop was used for resection, and a bipolar button electrode was used for vaporization.

A late systemic and brain metastasis from subcutaneous leiomyosarcoma of the right forearm: a case report and review of the literature.

Background: Leiomyosarcomas are rare malignant tumors which originate from smooth muscle cells and very seldom give rise to intracerebral metastases. Nearly all cases of intracranial metastases stem from leiomyosarcomas of the uterus. We present a 61-year-old Caucasian man who developed multiple intracranial and extracranial metastases from leiomyosarcoma of the right forearm, diagnosed and treated 9 years before the current presentation.

Stage pT0 after radical prostatectomy: a diagnostic dilemma.

Introduction: We assessed the misdiagnosed prostate cancer in radical prostatectomy (RP) specimens and the associated parameters.

Materials And Methods: A total of 3,821 patients were treated by RP. A meticulous process to identify misdiagnosed PCa in the specimen was followed.

[Centrifugal plaques with central atrophy and peripheral scale on the scalp].

A 62-year-old man presented with slowly progredient, centrifugal, peripherally hyperkeratotic, centrally atrophic, slightly pruritic lesions on his scalp for at least 9 months. A punch biopsy stained with hematoxylin-eosin (HE) revealed minimal epidermal acanthosis and chimney-like parakeratosis (cornoid lamella) around a follicle. Discrete spongiosis of the epidermis was observed, as well as a lymphocytic cell infiltration in the papillary dermis.

[Inflammatory juvenile conjunctival nevus (IJCN)].

Background: Pathologists may occasionally have difficulties in reliably assessing the dignity of tumour cells in histological sections, especially in nevi with junctional activity.

Patient History: This case history of a boy suffering from an inflammatory juvenile conjunctival nevus (IJCN) is reported with a follow-up period of 25 years. Seven years after first surgical treatment of a histologically proven nevus, a recurrent pigmented lesion within the former operation area aroused the suspicion of it being a malignant melanoma.
