Dermatologically challenging syphilis presentation.

An atypical early primary syphilis case presentation with multiple umbilicated papular lesions on the penis and a nonreactive syphilis serology was misdiagnosed as molluscum contagiosum. Over a period of eight weeks, prior to dermatologic consultation, the papules enlarged, ulcerated, and healed. New plaque and patch formation on the penis and scrotum led to a differential diagnosis of inverse psoriasis vs.

Efficacy of endoscopic ultrasound-guided fine-needle aspiration and core needle biopsy in the diagnosis of upper gastrointestinal submucosal lesions.

Introduction: Endoscopic ultrasonographically guided fine-needle aspiration (EUS-FNA) has been increasingly utilized to evaluate submucosal lesions of the upper gastrointestinal (UGI) tract. Our study aims to determine the efficacy of UGI EUS-FNA/core needle biopsy (CNB), including the frequency and cytomorphologic features of encountered submucosal lesions, and to investigate contributing factors including the role of rapid on-site evaluation (ROSE).

Methods: We analyzed all UGI submucosal lesions diagnosed at our institution by EUS-FNA/CNB from September 2008 through August 2015.

Racial differences in sexuality profiles among American, Japanese, and Japanese American men with localized prostate cancer.

Introduction: Although there were marked racial differences in the clinical outcomes among Japanese men (JP), Caucasian men (CA), and Japanese American (JA) men with localized prostate cancer, the effect of race/ethnicity on sexual profiles remains unclear.

Aim: To determine differences of sexual profiles in JP, CA, and JA with localized prostate cancer.

Methods: A total of 412 JP, 352 CA, and 54 JA with clinically localized prostate cancer were enrolled in separate studies of health-related quality of life outcomes.

Immunohistochemical expression of cyclooxygenage-2 in melanocytic skin lesions.

Background: Several reports have shown expression of cyclooxygenase-2 (COX-2) in malignant skin tumors. COX-2 has also recently been reported as a marker of malignant melanoma (MM).

Objective: Our aim was to investigate whether there is a difference in the immunohistochemical expression of COX-2 between malignant and benign melanocytic lesions of the skin.

Ileal inflammatory fibroid polyp causing chronic ileocolic intussusception and mimicking cecal carcinoma.

Inflammatory fibroid polyp (IFP) is a rare, idiopathic pseudotumorous lesion of the gastrointestinal tract. While mostly reported as solitary gastric lesions, multiple cases of small bowel IFPs are also reported. It is a documented cause of intussusception in adults.

Comparison of the clinical outcome after hormonal therapy for prostate cancer between Japanese and Caucasian men.

Objective: To investigate the impact of race on the effectiveness of hormonal therapy in patients with prostate cancer, by comparing the outcomes of Caucasian men (CM) and Japanese-American men (JAM) treated with hormonal therapy at one institution.

Patients And Methods: Fifty-nine CM and 105 JAM with prostate cancer were treated with hormonal therapy at The Queen's Medical Center in Honolulu. Age, stage, Gleason score, race, and pretreatment PSA levels were abstracted.
