Paraganglioma of the Seminal Vesicle Case Report and Review of the Literature

Paraganglioma of the spermatic cord: A case report and literature review

•

A paraganglioma, or an extra-adrenal catecholamine-producing tumor, is a clinically significant neuroendocrine tumor with an incidence of 3–8 cases per million population.

•

The majority of paragangliomas, 85–90%, occur in the adrenal glands and 98% are found in the abdomen.

•

Unlike pheochromocytomas, where only 10% are malignant, paragangliomas carry a 40–50% malignancy rare, and their development is part of a hereditary syndrome in 30% of cases.

•

The most common hereditary syndromes associated with paragangliomas are von Hipple-Lindau (VHL), multiple endocrine neoplasia 2 (MEN 2) and neurofibromatosis type 1 (NF1).

•

Herein we describe and review the 13th paraganglioma documented arising from the spermatic cord.

Introduction

Neuroendocrine tumors are a diverse and well-described entity with most arising from the gastrointestinal tract. A clinically significant example is the paraganglioma, or an extra-adrenal catecholamine-producing tumor.

Presentation of case

Herein we describe and review a paraganglioma arising from the spermatic cord in a 55 year old asymptomatic man.

Discussion

Paragangliomas are rare, with an incidence of 3–8 cases per million population. To date there are only 12 cases found in the literature.

Conclusion

In this article, we review our patient’s presentation, follow-up, and screening followed by a review of the literature of this fascinating tumor. Although rare, paraganglioma should be considered in the differential diagnosis of unusual groin masses. This work has been reported in line with the SCARE criteria (Agha et al., 2018).

Leiomyoma arising from the right seminal duct/seminal vesicle-Report of a rare case and review of the literature

We present a case of a patient with a large, symptomatic abdominal tumour, which finally could be classified as a leiomyoma arising from the right seminal duct/seminal vesicle. In computed tomography (CT) scan, it appeared as a 7.5 × 6.5 cm solid, supravesical mass. A cystoscopy as well as bilateral retrograde studies was normal, a transrectal ultrasound-guided biopsy and an ultrasound-guided transabdominal biopsy of the mass were inconclusive. Subsequently, we performed a tumour extirpation through a lower midline laparotomy. Histological examination showed a leiomyoma arising from the right seminal duct or seminal vesicle. In this article, we discuss clinical presentation, findings on imaging and management of this rare benign tumour and review the relevant literature where only 13 similar cases could be identified.
