Background: Musculoskeletal involvement occurs in 25% of patients with non-Hodgkin's lymphoma (NHL). Primary lymphoma in the joint is rare. It can present as a bone lesion or as atypical soft tissue proliferation. NHL has an increased incidence in patients with autoimmune rheumatic diseases., Case Presentation: We present a case in which non-Hodgkin's lymphoma was found coincidentally in the synovium during knee joint replacement surgery in a 69-year old woman with rheumatoid arthritis. Pigmented, vitreous tissue was resected, which turned out to be a diffuse large B-cell lymphoma after histological examination. The coincidental intraoperative finding of intra-articular non-Hodgkin's lymphoma was reported twice before, presenting as synovial proliferation in elbow and shoulder surgery. In a few other cases non-Hodgkin's lymphoma presented most often in the knee, as a bone lesion or, when soft tissue was involved, as arthritis., Conclusion: Non-Hodgkin's lymphoma should be considered in patients with autoimmune rheumatic diseases. In case of persistent arthritis, non-respondent to anti-inflammatory drugs, a biopsy might be warranted. Moreover, when arthroscopy or arthrotomy is planned, any atypical tissue should be sent for histological analysis. Early diagnosis of NHL can contribute to improved outcome of its rapidly developing treatment options.

Aim: A quick and reliable preliminary diagnosis is essential in the management of a same-day breast clinic. In a preclinical study we developed an alternative method of core wash cytology (CWC). This study is an evaluation of this new CWC method introduced into the clinical setting., Methods: From April 2008 to April 2009, biopsies were taken from lesions in the breast. CWC was obtained from core needle biopsy (CNB) with a modified technique and classified into the categories: malignant, suspicious for malignancy, atypical, benign and inadequate. CWC and CNB diagnoses were correlated with the histopathology of subsequently obtained resection specimens. The sensitivity and specificity were calculated., Results: CWC was obtained from 226 breast lesions. In 167 of these cases subsequent resection of the lesion was performed revealing 149 carcinomas and 18 benign lesions. Of the 149 malignant cases, 136 were considered as either malignant or suspicious for malignancy by CWC, 7 as atypical, 4 as benign and 2 as inadequate. None of the 18 benign lesions were classified as suspicious or malignant on CWC. Eight out of 149 resected carcinomas were not recognized as malignant by histological analysis of the CNB, while 7 of these cases the CWC was considered malignant. The sensitivity and specificity were 97% and 100%, respectively., Conclusions: In the vast majority of patients the modified CWC technique can provide a quick and reliable diagnosis of malignant breast lesions. Furthermore, combining CWC with CNB histology can improve adequate, preoperative recognition of the malignant character of breast lesions., (Copyright © 2010 Elsevier Ltd. All rights reserved.)

Objective: To determine the value of cytology in the workup of male breast lesions, important for the management in a same-day breast clinic., Study Design: A total of 146 fine needle aspirations (FNAs) from the male breast were classified in the categories malignant, suspicious, atypical, benign and inadequate. Cytohistologic correlation was done., Results: Histologic correlation was available in 85 cases. On FNA the 15 malignant cases were classified as malignant (n = 11), suspicious for malignancy (n = 2) or atypical (n = 2). Of the 35 benign lesions on histology 3 cases were classified as atypia and 1 as suspicious for malignancy on FNA. In the inadequate FNAs (n = 45), the corresponding histologic specimens were benign, no carcinomas were diagnosed. The sensitivity and specificity of the FNA compared to the definite resection diagnosis were 100% and 90.2%, respectively. The results were comparable with the outcomes of the reviewed studies on male breast lesions in the recent literature., Conclusion: Based on the nature of the benign breast lesions in man, a substantial number of inadequate FNAs were obtained. However, due to the good cytohistologic correlations in the group of malignant lesions, we can conclude that cytology remains an important diagnostic tool in the initial workup of male breast carcinomas.

Primary malignant lymphoma involving the ovaries is extremely rare. We present a unique case of a primary Non-Hodgkin's lymphoma (NHL) of both ovaries, preceded by an internal jugular vein trombosis (IJVT) as paraneoplastic syndrome. Currently, 36 months after surgical treatment of this FIGO Stage Ib, Ann Arbor Stage 2E NHL, the patient is clinically free of disease. Based on this case and a review of the literature it is concluded that paraneoplastic syndromes like spontaneous IJVT should prompt the clinician to make a thorough diagnostic work-up in search of an underlying malignancy, including the female genital tract.
