Cowper's gland hyperplasia: A potential pitfall at MRI of the prostate

MRI features are presented in a multicenter retrospective series of five patients with a unilateral masslike lesion seen in the genitourinary diaphragm at MRI performed for known or suspected prostate cancer. In all cases, the lesion appeared as an encapsulated 1.3 to 3.0 cm mass of heterogeneous low or intermediate T2 signal intensity in the genitourinary diaphragm, and targeted biopsy demonstrated benign Cowper's gland tissue. This entity is a potential imaging pitfall that could result in a diagnosis of an exophytic nodule of benign prostatic hyperplasia or local spread of prostate cancer. We present these cases to facilitate correct identification of Cowper's gland hyperplasia as an occasional finding at MRI of the prostate.

Rare prostate cancer mimic on multiparametric MRI: Cowper's gland hyperplasia

Multiparametric MRI and targeted biopsies of the prostate have been increasingly utilized in men with elevated PSA. It is important to recognize potential mimics of prostate cancer on MRI and on biopsy specimens. Familiarity with the location, imaging and histological appearance of Cowper's glands will prevent misdiagnosis and help avoid unnecessary biopsies. We present a case of Cowper's gland hyperplasia with a review of its imaging and histopathologic characteristics.

Metastatic Cancer of Cowper's Gland: A Rare Cancer Managed Successfully by Molecular Profiling

Cancer of Cowper's gland is a very rare cancer. This case represents the 9th case in the medical literature. As such, there are no phase II or phase III trials to guide treatment. In this article, we report the successful treatment of a patient over a 7-year period guided solely by molecular profiling. Through multiple cycles to treatment, the cancer was controlled using drugs targeting c-kit, as the cancer steadily increased the expression of c-kit. This report also documents the use of a novel drug combination based on sunitinib that was well tolerated and may warrant testing in other c-kit-dependent cancers.

A neglected gland: a review of Cowper's gland

Cowper's glands are pea sized glands present inferior to the prostate gland in the male reproductive system. They produce thick clear mucus prior to ejaculation that drains into the spongy urethra. Though it is well established that the function of the Cowper's gland secretions is to neutralize traces of acidic urine in the urethra, knowledge regarding the various lesions and associated complications of this gland is scarce. This review provides a comprehensive report on the development, function and various lesions associated with Cowper's gland.

Adenoid cystic carcinoma of Cowper's gland

We report an additional case of primary adenoid cystic carcinoma of Cowper's gland in an otherwise healthy asymptomatic 66-year-old man. Based on a review of similar lesions presenting in the head and neck, our treatment plan entailed pelvic exenteration followed by radiation therapy. Whether adenoid cystic carcinoma of Cowper's gland behaves as aggressively as it does in the head and neck remains unclear. However, in view of the extensive local invasion in our patient and a previously successful outcome, a combined surgical and radiation approach appears to be the most appropriate therapy.

Adenoid cystic carcinoma of the prostate: report of a case

Adenoid cystic carcinoma of the prostate is a rare but distinctive variant of prostatic adenocarcinoma. A case report is presented and the pathology, differential diagnosis and treatment modalities are discussed.

Urethral adenocarcinoma (possibly originating in the glands of Littre)

Adenocarcinoma involving the bulbomenbranous urethra is a rare disease. This disease is describe in a 30-year-old man and the surgical management is detailed. The adenocarcinoma described seems to have arisen from the periurethral glands of littre. Despite the radical nature of the tumor excision, it was possible to spare the distal penis in order to achieve a more normal appearance of the external genitalia.
