Male Patient With a History of Monoclonal B Cell Lymphocytosis Presenting with Breast Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: A Case Report and Literature Review
Background
Monoclonal B cell lymphocytosis (MBL) is defined as presence of clonal b cell population that is fewer than 5 × 10(9)/L B-cells in peripheral blood and no other signs of a lymphoproliferative disorder. Patients with MBL are usually monitored with periodic history, physical exam and blood counts. Here we presented a case of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in breast in a patient with a history of MBL.
Case Presentation
68-year-old male with history of MBL underwent mammogram for breast mass. It showed suspicious 4.4 x 1.6 cm solid and cystic lesion containing a 1.7 x 0.9 x 1.8 cm solid hypervascular mass. Patient underwent left breast mass excision. Histologic sections focus of ADH involving papilloma with uninvolved margins. Lymphoid infiltrates noted had CLL/SLL immunophenotype and that it consists mostly of small B cells positive for CD5, CD20, CD23, CD43, Bcl-2, LEF1. CT CAP and PET/CT were negative for lymphadenopathy. Bone marrow biopsy showed marrow involvement by mature B-cell lymphoproliferative process, immunophenotypically consistent with CLL/SLL. As intra-ductal papilloma completely excised and hemogram was normal tumor board recommended surveillance only for CLL/SLL.
Discussion
MBL can progress to CLL, but it can rarely be presented as an extra-nodal mass in solid organs. We described a case of MBL that progressed to CLL/ SLL in breast mass in a male patient. This is the first reported case in literature where MBL progressed to CLL/ SLL of breast without lymphadenopathy. Upon literature review 8 case reports were found where CLL/SLL were described in breast tissue. 7 of them were in females and 1 one was in male. Two patients had CLL before breast mass but none of them had a history of MBL. 3 described cases in females had CLL/SLL infiltration of breast along with invasive ductal carcinoma. So, a patient with MBL can progress to involve solid organs despite no absolute lymphocytosis and should be considered in differentials of a new mass. Although more common in females, but it can occur in males as well. It’s important to consider the possibility of both CLL/SLL and breast cancer existing simultaneously.

Metastatic Prostate Cancer Presenting as Pleural and Pericardial Metastases: A Case Report and Literature Review
Background
Metastatic prostate cancer typically manifests with metastases to the lungs, bones, and adrenal glands. Here, we report a unique case where the initial presentation involved pleural nodules, subsequently leading to the discovery of pleural and pericardial metastases.
Case Presentation
Our patient, a 73-year-old male with a history of active tobacco use disorder, COPD, and right shoulder melanoma (2004), initially presented to his primary care physician for a routine visit. Following a Low Dose Chest CT scan (LDCT), numerous new pleural nodules were identified. Physical examination revealed small nevi and skin tags, but no malignant characteristics. Initial concerns centered on the potential recurrence of malignant melanoma with pleural metastases or an inflammatory condition. Subsequent PET scan results raised significant suspicion of malignancy. PSA was 2.41. Pleuroscopy biopsies revealed invasive nonsmall cell carcinoma, positive for NKX31 and MOC31, but negative for S100, PSA, and synaptophysin. This pattern strongly suggests metastatic prostate cancer despite the absence of PSA staining. (Stage IV B: cTxcN1cM1c). A subsequent PSMA PET highlighted extensive metastatic involvement in the pericardium, posterior and mediastinal pleura, mediastinum, and ribs. Treatment commenced with Degarelix followed by the standard regimen of Docetaxel, Abiraterone, and prednisone. Genetic counseling and palliative care services were additionally recommended.
Discussion
Prostate cancer typically spreads to bones, lungs, liver, and adrenal glands. Rarely, it appears in sites like pericardium and pleura. Pleural metastases are usually found postmortem; clinical diagnosis is rare. Pericardial metastases are exceptionally uncommon, with few documented cases. The precise mechanism of metastatic dissemination remains uncertain, with theories suggesting spread through the vertebral-venous plexus or via the vena cava to distant organs. Treatment approaches vary based on symptomatic effusions, ranging from pericardiocentesis, thoracocentesis to chemotherapy, radiotherapy, and hormone therapy. Studies have shown systemic docetaxel to be effective in managing pleural and pericardial symptoms. Despite their rarity, healthcare providers should consider these possibilities when encountering pleural thickening or pericardial abnormalities on imaging studies.
Conclusions
Pleural and pericardial metastases represent uncommon occurrences in prostate cancer. Continued research efforts can facilitate early detection of metastatic disease, enabling more effective and precisely targeted management strategies when symptoms manifest.
