Abstract
Abstract
Background
Adenomatoid tumor is a very rare benign neoplasm of mesothelial origin affecting mainly female and male genital tracts. The diagnosis is challenging as this tumor mimics many differential diagnoses. The current literature offers only some case reports and short series of adenomatoid tumors.
Case presentation
A 47-year-old patient with unremarkable medical history presented for chronic mild pain of the right testis evolving for months. The physical examination shows a palpable right intrascrotal nodule of 10 mm in greatest diameter. The nodule was painful, mobile with firm consistency. The laboratory investigations were within normal limits, the scrotal ultrasonography showed a well-circumscribed predominantly hyperechoic intrascrotal nodule in the right epididymal head with heterogeneous echostructure. Excisional biopsy of the lesion was performed and the histopathological analysis showed a well-circumscribed tumor with microcystic and trabecular architecture made of small interconnected tubules and cysts lined by flattened cells with prominent vacuolization and thread-like bridging strands, consistent with an epididymal adenomatoid tumor. The postoperative course was uneventful and the patient was discharged. Four months after surgical treatment, the patient has no sign of the disease.
Conclusion
Testicular adenomatoid tumors are uncommon benign neoplasms with diagnostic challenge. Adenomatoid tumors arising in epididymis are managed by excisional biopsy with testis-sparing surgery avoiding unnecessary orchidectomy.

Appendageal tumors and tumor-like lesions of the testis and paratestis: a 32-year experience at a single institution. Hum Pathol 2020; 103:25-33. [PMID: 32619438 DOI: 10.1016/j.humpath.2020.06.006] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 06/17/2020] [Accepted: 06/19/2020] [Indexed: 01/18/2023]
Abstract
The testicular hilum and paratestis contain several embryologically diverse anatomic structures, including the spermatic cord, tunica vaginalis, epididymis, rete testis, and several other embryonic remnants. Several benign and malignant lesions arise from these morphologically distinct structures, and owing to their proximity, it is challenging to classify and subsequently stage these tumors. Herein, we conducted a retrospective review of the paratesticular appendageal and rete testis tumors and tumor-like lesions diagnosed at our department from 1985 to 2016. Soft-tissue lesions/tumors were excluded. A total of 146 paratesticular appendageal and rete testis tumors and tumor-like lesions were identified. Most were benign (n = 107; 73%). Adenomatoid tumor (26%) was the most common benign tumor, followed by different types of cysts (19%), mesothelial hyperplasia (18%), serous cystadenoma (5.5%), and rete testis adenoma (4%). Malignant lesions comprised 23% of the cases, with mesothelioma the most common (15%), followed by adenocarcinoma of the rete testis (4%), serous cystadenocarcinoma (2%), and papillary and clear cell adenocarcinoma of the epididymis (2%). Finally, serous borderline tumors and melanotic neuroectodermal tumor (retinal anlage tumors) comprised the remaining 4% of cases. In conclusion, a wide range of benign and malignant lesions can arise from the paratesticular region. Awareness of these lesions and their histologic spectrum is crucial to avoid diagnostic pitfalls and to allow pathologists to establish a correct diagnosis and subsequent treatment plan.

Abstract
Extracellular tumors found with the spermatic cord, known as neoplasms, are usually identified to be benign. However, the accurate and timely diagnosis of spermatic cord masses is highly crucial, especially when most results are often overlooked or unclear. In this review, we discuss the anatomy and embryology of the spermatic cord. Upon rooting these fundamental concepts, we discuss an array of benign and malignant neoplastic tumors, including their origin, pathological features, clinical evaluation and management, as well as other case-specific characteristics of unique presentation. Many of these neoplasms are based on local neurological, vascular, muscular, bone, soft tissue, or lymphatic origin, while others have metastasized from particular areas of the body.

Abstract
BACKGROUND Inflammatory pseudotumour refers to a non-malignant tumour-like mass resulting from an inflammatory reaction that is composed of granulation tissue with leukocyte infiltration that commonly occurs in the paediatric or young adult population. These tumours occur more commonly in the lungs and the orbit but rarely does it affect the gastrointestinal tract. It poses a clinical diagnostic challenge since it is a benign condition than can mimic the malignant counterpart. Our case is a rare presentation of the caecal pseudotumour in the presence of a right undescended abdominal testis evaluated as a caecal tumour with a differential diagnosis of a testicular malignancy. CASE PRESENTATION We report a 53-year-old male who presented with clinical signs suggestive of right colon tumour and undescended right testis. Intra-operatively, a caecal mass was found with no clearly discernable appendix and extensive adhesion of the right colon to the retroperitoneum, to the liver and gall bladder. A testis was found adherent to the posterior aspect of the caecum and terminal ileum. A right hemicolectomy was performed. Histopathology findings revealed an inflammatory mass with abundant fibroblast proliferation and chronic inflammatory cells infiltrate, involving bowel wall and periceacal adipose tissue; no malignant cells were identified. The testis had within it an adenomatoid tumour nodule. He had uneventful recovery and was discharged home 7 days post-operatively. At the moment, he is symptoms free. CONCLUSIONS The occurrence of right colonic inflammatory pseudotumour and co-existent adenomatoid testicular tumour arising from a cryptorchid testis is very unusual. This would make one incline towards a malignant testicular lesion in the presence of cryptorchidism. Testicular adenomatoid tumour is a rare benign neoplasm, mostly affecting fully descended testis and usually does not warrant orchidectomy for purposes of preserving testicular function. On the other hand, surgical resection remains the only safe and curative treatment option available for inflammatory pseudotumours.

Abstract
Extratesticular cystic and solid scrotal masses are commonly encountered in pediatrics. The most common extratesticular malignancy is paratesticular rhabdomyosarcoma. The remainder of the common pathologies encountered -- appendage torsion, epididymitis and varicoceles -- are mostly benign. These frequently encountered benign lesions are confidently differentiated from paratesticular rhadbomyosarcoma using high-frequency scrotal sonography in combination with clinical features. Less commonly encountered extratesticular masses may not be as easily classified; however, these also have distinguishing features that can enable differentiation from malignancy. This review discusses the sonographic findings, and relevant clinical and pathological manifestations of the more unusual extratesticular masses encountered in two tertiary pediatric institutions during a 10-year period. While these extratesticular pathologies are encountered relatively infrequently, recognition of their manifestations enables appropriate management.

Abstract
Palpable scrotal masses are common scenarios in any clinical practice. These tumors can be painful or painless, can be intratesticular or extratesticular and be cystic or solid. The distinction between benign and malignant tumors is of utmost importance to enable an adequate and differentiated therapy of patients. In clinical diagnostics besides the medical history, examination of the inguinoscrotal region, laboratory diagnostics and ultrasound examination of the inguinoscrotal area play a decisive role. During the last few years the increased use of contrast-enhanced ultrasound has helped clinicians in differentiating scrotal tumors. Malignant tumors are of particular importance because this entity is the most frequent malignant disease among younger men and according to the Robert Koch Institute there are approximately 3900 new patients in Germany each year (Robert Koch Institute, Krebs in Deutschland 2007/2008 and 2012).
