Histiocytic sarcoma (HS) is a rare hematopoietic malignancy originating from the monocyte/macrophage bone marrow lineage. HS can occur in isolation or in association with other hematological neoplasms such as non-Hodgkin lymphoma (NHL), myelodysplasia, or acute leukemia. Clinically, HS can affect lymph nodes, gastrointestinal tract, skin, bone marrow, and spleen as well as the central nervous system. Most cases of HS follow an aggressive clinical course, with most patients dying of progressive disease within one year of diagnosis

Background: Enlarged lymph nodes (ELN) pose a great diagnostic challenge. They may represent the first clinical finding of a hematologic disease or other malignancy and may be an indication of a wide range of infectious and non-infectious diseases. Because many patients undergo percutaneous biopsy, surgical excisional biopsy is not often considered.

Objectives: To analyze indications for a patient's referral for surgical biopsy of ELN and diagnostic steps to follow until referral, and to determine the number of ELN.

Methods: A retrospective study was conducted of prospectively collected data of patients who underwent surgical biopsy of ELN from January 2004 to December 2013.

Results: Of 118 patients who underwent surgical biopsy of ELN, only 52 (44%) had needle biopsy (NB) before referral. Lymphoma was diagnosed by NB in 24 (46%) of the referred patients. In patients with a previous diagnosis of lymphoma, NB of ELN yielded a sensitivity of 67% and specificity of 79%. In patients with lymphadenopathy but with no previous history of malignancy, sensitivity for lymphoma was 68% and specificity was 71%. The investigative time period until final diagnosis was 3 months in patients who had NB but only 1.25 months in patients who were referred directly for surgery (P < 0.0001).

Conclusions: Surgical biopsy of ELN still has a place in the clinical evaluation of patients with ELN. Surgery may significantly reduce the length of investigation and prevent unnecessary diagnostics, especially in patients with suspected lymphoma recurrence.

Background: Silicone breast augmentation is a common cosmetic surgery. Previous case reports demonstrated lymphadenopathy in the presence of implant ruptures.

Objectives: To investigate the association between enlarged axillary lymph nodes and silicone implant ruptures as seen on breast magnetic resonance imaging (MRI).

Methods: Two groups were derived retrospectively from breast MRI reports in our institution for the period December 2011–May 2014. A search of our hospital records for "silicone" and "lymph node" was performed (group A), and the relationship between the presence of enlarged nodes and ruptures was evaluated. The prevalence of ruptures in the presence of nodes was calculated and the association between MRI imaging features and ruptures evaluated. A search for "silicone" and "implant rupture" was performed (group B) and, as for group A, the relationship between the presence of ruptures and nodes was evaluated and the prevalence of enlarged nodes in the presence of ruptures calculated.

Results: Group A comprised 45 women with enlarged nodes. Intracapsular ruptures were associated with nodes (P = 0.005), while extracapsular ruptures showed a trend of association with nodes (P = 0.08). The prevalence of ruptures in the presence of nodes was 31.4%. Nodes associated with ruptures showed a strong silicone signal (P = 0.008) and absent enhancement (P = 0.005). Group B comprised 73 women with ruptures. Enlarged nodes were associated with both intra- and extracapsular ruptures (P < 0.001 and P = 0.002 respectively). The prevalence of nodes in the presence of ruptures was 22.2%.

Conclusions: Enlarged axillary nodes were associated with ruptures in two groups of patients. This finding can guide clinical decisions when either enlarged nodes or ruptures are encountered in patients with silicone implants. The association between silicone lymphadenopathy and implant rupture raises concerns regarding the role of rupture in silicone-induced systemic disease.

Background: Kikuchi-Fujimoto disease is a benign and self-limited disease, first reported in Japan in 1972. The characteristic features of this disorder include lymphadenopathy and fever.

Objectives: To summarize our experience with Kikuchi disease with regard to clinical manifestations and outcome.

Methods: The patients included in the study were those diagnosed with Kikuchi disease during the years 2005–2008 in two departments of internal medicine at Sheba Medical Center.

Results: We identified five patients with Kikuchi disease; four of them were women and the mean age was 22.6 years. All the patients had cervical lymphadenopathy; three had other sites of lymphadenopathy. Four of the patients had fever higher than 39ºC. Two of them had splenomegaly and three reported weight loss. Three of the five patients experienced a relapse of the disease and were treated with steroids or non-steroidal anti-inflammatory agents. The diagnosis was confirmed in all the patients by an excisional biopsy of lymph node.

Conclusions: Kikuchi disease must be considered in every young patient with fever and lymphadenopathy. The disease usually has a benign course.
