Metachronous Bilateral Testicular Plasmacytoma After an Initial Soft Tissue, Extramedullary Plasmacytoma

Testicular plasmacytoma is a rare extramedullary manifestation of plasma cell dyscrasia. We report a case of a 53-year-old man who presented with a metachronous testicular lesion originating from a soft tissue plasmacytoma of the oral cavity. He underwent radical orchiectomy and a year later, presented with testicular plasmacytoma in the contralateral testis. He received induction chemotherapy, autologous stem cell transplantation with high dose melphalan and maintenance with lenalidomide, as he refused orchiectomy and achieved complete remission. However, six months post-transplant, he relapsed with localized disease in his testis, received second-line chemotherapy, after refusing orchiectomy and still remains in partial remission and alive.

Metastasis of colorectal carcinoma in the testis: first sign of peritoneal disease

Metastases of colorectal carcinoma (CRC) in the testis are very rare and indicate an advanced stage of disease. In this case report, we present a patient with adenocarcinoma in the sigmoid colon with metastasis in the right testis. Testicular metastasis of CRC is mostly diagnosed late because of their low incidence rate. Patients with CRC and testicular metastasis have a poor prognosis. In this case, the patient turned out to have peritoneal metastasis and one should be aware that testicular metastasis could be the first sign of widespread disease.

Multiple myeloma with testicular involvement: A case report

A case of multiple myeloma with testicular involvement is rare. We report a 72-year-old male with testicular infiltration as extramedullary disease of IgD λ-type multiple myeloma. The patient received systemic treatment, which included high orchiectomy, anticancer chemotherapy, and radiation therapy for bone metastasis. Eight months after the initial diagnosis, he remains alive.

The testis is a rare location for extramedullary disease of multiple myeloma. Testicular involvement of multiple myeloma indicates a poor prognosis. The particular treatment strategy for extramedullary disease in multiple myeloma remains unclear. Testicular involvement of multiple myeloma is reviewed and discussed in this paper.

Multiple Myeloma of Testes and Spermatic Cord on 18F-FDG PET/CT

Extramedullary multiple myeloma (EM) has negative prognostic implications on the overall survival as well as progression-free survival. Testis is a rare site of EM, which can be a part of diffuse involvement in multiple myeloma or a site of recurrence in patients with remission. We present a case of EM of testes and left spermatic cord in an 80-year-old man who presented with painless progressive enlargement of the scrotum. F-FDG PET/CT revealed tracer avidity of both testes and left spermatic cord. Bilateral radical orchidectomy was subsequently performed, and the diagnosis of multiple myeloma was confirmed on histopathology.

Bilateral synchronous plasmacytoma of the testis

Extramedullary plasmacytoma (EMP) is usually seen in the head and neck regions and in the upper respiratory, gastrointestinal, and central nervous systems. Testis is a rare site for EMP, and bilateral synchronous testicular plasmacytoma occurring as an isolated event at initial presentation has been reported only once previously. We present herein the second such report in a 70-year-old man who underwent bilateral orchidectomy.

Plasmacytoma of the testis in a patient with relapsed and refractory multiple myeloma: Case report and review of the literature

Testicular plasmacytoma, whether occurring as a primary lesion or as a reflection of underlying multiple myeloma (MM), is a rare disease. We report the case of a 38-year-old male with multiply relapsed MM, who was found to have a testicular plasmacytoma. He presented with a gradually enlarging scrotal mass. Following orchidectomy, pathologic examination of the specimen demonstrated a plasmacytoma. In the context of active MM, the specimen was also sent for cytogenetic analysis but this was unhelpful in guiding a chemotherapy regime, which still continues at time of reporting. Although a rare lesion, there remains no definitive treatment protocol for the management of testicular plasmacytoma representing an extramedullary manifestation of MM.

An extramedullary plasmacytoma in the testicle: A case report and review of the literature

We present a rare case of testicular extramedullary plasmacytoma (EMP) in a 43-year-old man with multiple myeloma and diffuse systemic involvement refractory to chemotherapy. Multiple myeloma is typically found within the bone marrow and rarely involves other organs and sites. EMPs are most frequently associated with the head and neck region, but in rare cases testicular involvement have been seen. These mimic other causes of testicular swelling and therefore require a full diagnostic workup and management similar to that of any scrotal pathology. Radical inguinal orchiectomy is the treatment of choice with the addition of adjunct or salvage radiation therapy if necessary. The prognosis with these lesions is poor and in cases of primary testicular plasmacytoma, progression to multiple myeloma is likely.

Incidental discovery of a testicular plasmacytoma at initial presentation of multiple myeloma

Testicular plasmacytomas are a rare phenomenon reported in the literature and they can occur as a solitary plasmacytoma, as a recurrence of multiple myeloma, or concurrently in an active myeloma. We report the case of a 43-year-old man who presented with back pain and was diagnosed with multiple myeloma. A CT scan performed to determine the extent of disease revealed an incidental mass in the testicle. Immunohistochemical staining of the mass revealed monoclonal cytolpasmic IgA in the tumor cells and serum studies showed this same immunoglobulin. Following orchiectomy, radiotherapy to the vertebra, chemotherapy with bortezomib, dexamethasone, and doxorubicin, and an autologous bone marrow transplant, the patient is alive twelve months after diagnosis and is in complete remission.

Paratesticular solitary plasmacytoma

Primary solid neoplasms of the extratesticular tissues are rare. The reported prevalence rate of paratesticular neoplasms is between 3% and 16% of all patients referred for scrotal ultrasonography. A plasmacytoma is a discrete, solitary mass of malignant monoclonal plasma cells that can arise in any part of the body. In this report, we present a case of a paratesticular solid mass detected in an 80-year-old patient that proved to be primary extraosseous plasmacytoma on surgery, and discuss its sonographic features.

Primary plasmacytoma of the testicle: a case report

Introduction

Extramedullary plasmacytoma is a rare plasma cell neoplasm. Plasmacytomas are most commonly found in the head and neck region, but can occur in many other locations. They rarely occur in the testis, and are commonly associated with concurrent multiple myeloma at the time of diagnosis. Isolated plasmacytoma of the testis is exceedingly rare, with few cases reported in the literature.

Case presentation

A 72-year-old Caucasian man presented with a painless testicular mass treated by orchiectomy. The mass was determined to be plasmacytoma on pathological examination. At the time of diagnosis, our patient did not have multiple myeloma, and is currently undergoing chemotherapy for treatment of his disease.

Conclusion

Isolated plasmacytoma of the testicle is a rare cause of testicular mass, and is seldom reported in the literature. Patients with this disease require careful monitoring because of their high risk of progression to multiple myeloma. The diagnosis of testicular plasmacytoma can be challenging for primary care doctors and urologic specialists. This condition should be in the differential diagnosis in elderly men.
