It had been observed that many male Sitka black-tailed deer (Odocoileus hemionus sitkensis) on Kodiak Island, Alaska, had abnormal antlers, were cryptorchid, and presented no evidence of hypospadias. We sought to better understand the problem and investigated 171 male deer for phenotypic aberrations and 12 for detailed testicular histopathology. For the low-lying Aliulik Peninsula (AP), 61 of 9...

Ductal carcinoma in situ (DCIS) is an often-diagnosed breast disease and a known, non-obligate, precursor to invasive breast carcinoma. In this review, we explore the clinical and pathological features of DCIS, fundamental elements of DCIS biology including gene expression and genetic events, the relationship of DCIS with recurrence and invasive breast cancer, and the interaction of DCIS with t...

OBJECTIVE We report a case of supernumerary testis, a rare anomaly with only around 100 cases reported in the literature. METHODS We describe the case of a 26-year-old man who consulted for a left paratesticular tumor. Physical examination and ultrasound showed a 2-cm nodular lesion over the left epididymis. The lesion was confirmed as supernumerary testis by surgical examination and biopsy...

Ductal carcinoma in situ (DCIS) of the breast is a heterogeneous group of lesions with diverse malignant potential and a range of controversial treatment options. It is the most rapidly growing subgroup in the breast cancer family, with more than 36,000 new cases diagnosed in the United States during 1997. Most new cases are nonpalpable and discovered mammographically. In this overview, a varie...

Primary ectopic breast carcinoma in male is very rare. We report a case on a 52-year-old gentleman who presented initially with bilateral lesions in his axilla and after delayed diagnosis the right lesion was confirmed as an ectopic breast carcinoma. We reviewed the literature and discussed the significance of the case.

BACKGROUND Non-small cell lung cancer (NSCLC) presents as a progressive disease spanning precancerous, preinvasive, locally invasive, and metastatic lesions. Identification of biological pathways reflective of these progressive stages, and aberrantly expressed genes associated with these pathways, would conceivably enhance therapeutic approaches to this devastating disease. METHODOLOGY/PRINCI...

INTRODUCTION A prospective study to evaluate the reliability of cystoscopy was performed with fluorescence (photodynamic diagnosis, PDD) compared with standard white light (WL) cystoscopy in patients with solitary carcinoma in situ (CIS), undergoing BCG treatment. MATERIALS AND METHODS Between February 2004 and March 2006, 49 patients suffering from CIS were enrolled in the study. Patients ag...

Microscopic patterns of thirty-four urothelial tumors of the urinary bladder of water buffaloes from the Marmara and Black Sea Regions of Turkey are here described. All the animals grazed on lands rich in bracken fern. Histological diagnosis was assessed using morphological parameters recently suggested for the urinary bladder tumors of cattle. Papillary carcinoma was the most common neoplastic...

Large format histology offers several unique advantages over traditional tissue processing. Over 12 years of experience with this technique provide insight into its limitations and benefits. We conducted a prospective multiyear analysis of the potential advantages of large format histology. 656 cases were examined prospectively over an eight-year period. In 172 cases the sign-out pathologist do...

BACKGROUND Whereas testicular metastases are in themselves a rare entity, testicular secondaries from an appendiceal carcinoma have not yet been described. The case also illustrates the diagnostic dilemma of a tumour presenting as epididymo-orchitis. CASE PRESENTATION The authors present a case of an appendiceal carcinoma that, two years after radical therapy, manifested as a secondary in the...
