Bilateral Synchronous Testicular Involvement in Multiple Myeloma. Case Report and Review of the Literature

Unusual Extramedullary Manifestation in Multiple Myeloma: Bilateral Synchronous Testicular Infiltration

ABSTRACT

A 73-year-old man with multiple myeloma (initial diagnosis 21 months earlier) was referred to our center for a whole-body 18 F-FDG PET/CT. We detected a bilateral synchronous testicular manifestation, which was confirmed by histopathology after orchiectomy. Besides hypermetabolic lesions in the spine and ribs (most likely old fractures), known osteolysis showed no uptake. Extramedullary manifestation occurs in 13% to 20% of cases, among these 4% demonstrate testicular manifestation, which is associated with poor survival rates. Optimal therapy management is still unclear, due to limited data. To the authors' knowledge, so far only 3 comparable cases have been described.

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.

Rare case of male breast cancer and axillary lymphoma in the same patient: an unique case report

Breast cancer in men is uncommon, and even more rare is the simultaneous presentation of two different malignancies. A 39-year-old man was diagnosed with both breast cancer and axillary lymphoma. Familiar history revealed that his mother died because of breast cancer. The patient underwent fine needle aspiration leading to the diagnosis of malignant lesion. Modified radical mastectomy was performed. Histology revealed an infiltrating ductal carcinoma 2.8 cm wide, grade 2, with vascular and lymphatic invasion. Surprisingly, one of the second level nodes was confirmed as a high-grade large B cell non-Hodgkin's lymphoma. No family inheritance or gene mutations (BRCA 1 and 2) were found. The patient underwent local radiotherapy, followed by 6 chemotherapy courses (RCHOP) and treatment with tamoxifen 20 mg/daily. To our knowledge, this is the first case reported in literature of male breast cancer and axillary lymphoma simultaneously confirmed in the same patient.

Primary testicular plasmacytoma with hydrocele of the testis

A case of primary testicular plasmacytoma complicated with hydrocele of the testis is reported. An 86-year-old man presented with hydrocele of the right testis. High inguinal orchiectomy was performed as the preoperative aspiration cytology of the hydrocele fluid showed atypical cells. Immunohistochemical study of the right testis revealed testicular plasmacytoma positive for IgG. He remained well 9 months after the orchiectomy. This is the second reported case where the preoperative diagnosis of testicular plasmacytoma was made based on the hydrocele fluid cytology.
