Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is rare among skin malignancies. C-ALCL usually manifests as reddish or violet nodules. Surgical excision or radiation therapy is generally considered as first-line therapy, but a clinically aggressive disease may require multiagent chemotherapy. Establishing a proper diagnosis of C-ALCL is challenging but should be made to avoid inappropriate treatment and its consequences. The authors report a case of medically resolved C-ALCL in an 81-year-old man presented with well-defined nodular lesions on the forehead.

Actinomycosis can mask malignant diseases. This paper reports a case of colonic diffuse large B-cell lymphoma (DLBCL), which was misdiagnosed as abdominal actinomycosis. A 76-year-old woman presented with right flank pain and weight loss. Abdominal CT and colonoscopy revealed a huge ascending colon mass. Despite the initial impression of a malignancy, a colonoscopic biopsy revealed no malignant cells, but sulfur granules and a filamentous organism suggesting actinomycosis. Intravenous penicillin G was administered under the impression of abdominal actinomycosis but her condition deteriorated rapidly. Follow up CT showed markedly increased colon mass and new multiple nodular lesions around the ascending colon. Sono-guided percutaneous biopsy of the nodular lesion was performed. The pathological result was DLBCL. The patient was scheduled to undergo chemotherapy but the patient expired due to cancer progression. The diagnosis of gastrointestinal infiltrating tumors is often difficult because a superficial biopsy usually does not provide a confirmative diagnosis. This case highlights the difficulty in making a correct diagnosis of lymphoma due to the concomitant actinomycosis. Malignant conditions must be considered in cases of actinomycosis with no response to antimicrobial therapy.

OBJECTIVETo analyze the clinical course of a very elderly patient with advanced diffuse large B cell lymphoma (DLBCL), so as to explore the incidence, prognosis and treatment of DLBCL and to analyse the prognostic and therapeutic significance of molecular subtype.

METHODSThe clinical history, auxiliary examinations, clinical diagnostic standards, therapeutic methods, biopsy and autopsy of this patient were retrospectively analyzed; the incidence, current treatment status, molecular biological features, and prognostic and therapeutic significance of molecular subtype were studied.

RESULTSAfter admission, this patient was diagnosed as non-GCB DLBCL, NOS, stage IV B and in the high risk group (IPI = 5, ECOG = 2). She achieved a decent partial response after many times of imunochemotherapy, but his disease status soon progressed. The liver occupying biopsy revealed non-GCB, while the spleen tumor pathology revealed GCB; pathological typing of these two methods was completely opposite. Autopsy pathological diagnosis showed that the death causes included extensive tumor metastasis, dyscrasia and respiratory circle failure.

CONCLUSIONIncidence of aged patients with DLBCL is high, and the disease is aggressive; the treatment is low responsive and difficult, and new therapeutic methods are needed. Gene expression profile (GEP) can provide molecular subtype and potential pathogenic mechanism, which can promote the development of new targeted therapy and individualized treatment.

OBJECTIVETo investigate the clinicopathological manifestation, immunophenotypic features and prognostic factors of patients with primary breast DLBCL (PB-DLBCL).

METHODSTwelve cases of PB-DLBCL, diagnosed according to the 2008 World Health Organization classification of tumors of hematopoietic and lymphoid tissues, were retrospectively studied.

RESULTSMost patients were admitted to hospital because of painless unilateral breast mass. Out of 12 cases, 5 were in Ann Arbor stage I (41.7%), 7 case were in stage II (58.3%). Most (89.9%) were assigned to non-GCB subtypes, 11.1% were classified as GCB subtype. The patients who recepted treatment were sensitive to chemotherapy and they were all alive following 12 to 92 months.

CONCLUSIONPrimary breast DLBCL is extremely rare without specific clinical features. They all respond well to chemotherapy and show good prognosis.

Polyarthritis is a common manifestation of rheumatologic disorders; however, paraneoplastic arthropathies also arise as polyarthritis or polymyalgia, particularly in patients with myelomas, lymphomas, acute leukemia, and solid tumors. Because paraneoplastic syndromes, in some instances, might be manifested before a cancer diagnosis, they are difficult to diagnose and are often misdiagnosed. We experienced a 63-year-old female patient who had nonspecific arthritis on both hands and feet accompanied by fever. She had been diagnosed as rheumatoid arthritis and treated with prednisolone and disease modifying anti-rheumatic drugs (DMARDs) including methotrexate and anti-tumor necrosis factor agents. Her arthritis did not respond with anti-rheumatic treatment and diffuse large B-cell lymphoma was diagnosed by bone marrow biopsy. After 6 cycles of chemotherapy, her arthritis was improved as well as underlying lymphoma.

OBJECTIVETo explore the clinical and prognostic features as well as treatment response of childhood B-cell non-Hodgkin's lymphoma/acute lymphoblastic leukemia (B-NHL/B-ALL), so as to better modify the treatment for further improving the prognosis.

METHODSThe clinical data of 43 patients with newly-diagnosed childhood B-NHL/B-ALL from July 2005 to December 2013 in West China Second Hospital of Sichuan University were retrospectively analyzed with particular focus on clinical presentations, laboratory findings and histology. Among them 26 patients received B-NHL-2010 protocol and 17 patients received LMB-89 protocol treatment. Kaplan-Meier method was used to compare the survival rates between groups, while multiple factor logistic regression was used to identify the prognostic factors.

RESULTS(1) The median age at diagnosis was 7.58 (2.42-13.67) years. The male-to-female ratio was 2.9 : 1. No significant difference was found in the median age at diagnosis between male and female children with B-NHL/B-ALL (P = 0.837). (2) Burkitt's lymphoma was the most common (34/43, 79.07%), followed by diffuse large B cell lymphoma (4/43, 9.3%), ALL-L3 (3/43, 6.98%) and others (2/43, 4.65%) in decreasing frequency. (3) According to St. Jude staging classification, 4 patients (9.30%) were divided into stage I, 9 patients (20.93%) into stage II, 23 patients (53.49%) into stage III and 7 patients (16.28%) into stage IV; (4) Clinically, the common predilection sites were as following: ileocecus (11/43, 25.58%), nasopharynx (10/43, 23.26%), faciomaxillary (9/43, 20.93%), superficial lymphadenopathy (8/43, 18.60%), other sites such as mediastinum and bone marrow (5/43, 11.63%). (5) With a median follow up of 24 months (0.7-105 months), the 2-year overall survival (OS) rate and event-free survival (EFS) rate were 79.8% ± 6.5%% and 71.0% ± 7.2%, respectively. The 2-year OS and EFS rates in patients treated with B-NHL-2010 protocol were 79.1% ± 8.4% and 74.1% ± 8.4%, while those in patients treated with LMB-89 protocol were 87.5% ± 8.3% and 66.7% ± 12.4%, respectively, but there was no significant difference between them (P > 0.05). The 2-year EFS rate in patients with LDH > 2N and bone marrow infiltration were significantly lower than that of other groups (P < 0.05). (6) 8 patients (18.6%) relapsed. The median relapsed time was 6 months (2-9 months). 1 patient suffered progressive disease. Male, systemic symptom, elevated LDH, bone marrow and CNS infiltration and advanced stage (stage III and stage IV) were associated with relapse /progressive disease. Logistic regression analysis showed that LDH > 2N was an independent unfavorable prognostic factors (OR = 31.129, P = 0.02).

CONCLUSIONOutcome of B-NHL/B-ALL is greatly improved by current intensive and short-time chemotherapy regimen. The 2-year event-free survival (EFS) rate is 71.0% ± 7.2%. There is no significant difference in EFS rate between patients treated with B-NHL-2010 protocol and LMB89 protocol. The long-term survival rate in patient with advanced disease need to be further improved.

OBJECTIVETo evaluateclinical features, treatment and outcomes of patients diagnosed with primary breast diffuse large B-cell lymphoma（DLBCL）.

METHODSClinical data were analyzed for all patients diagnosed with primary breast DLBCL（n=21）. Kaplan-Meier method was used to estimate 5- year overall survival（OS）rate, and the difference was compared by Log- rank test.

RESULTSThe 21 cases of patients with primary breast DLBCL were all female with median age at diagnosis as 48 years （range 21-64 years）. 13 patients had International Prognostic Index（IPI）of 0, 6 IPI 1, and 2 IPI 2. The 5- year OS rates of CHOP/R- CHOP and R±DICE after R±EPOCH groups were 40.0% and 72.2% , respectively（P=0.035）. The central nervous system relapse rate of CHOP/R-CHOP and R±DICE after R± EPOCH groups were 16.7% and 6.7%（P=0.500）, respectively. The 5- year OS rates of patients with primary breast DLBCL staging Ⅱ E-Ⅲ E and Ⅰ E were 21.4% and 83.3% , respectively（P=0.025）.

CONCLUSIONPrimary breast DLBCL was rare. The patients of primary breast DLBCL with chemotherapy regimen of R±DICE after R±EPOCH might have a better prognosis and lower relapse rate of central nervous system; the primary breast DLBCL patients staging ⅡE-ⅢE might have a poor prognosis.

OBJECTIVETo investigate the prognosis value of early and interim ¹⁸F-FDG-PET/CT scan in patients with diffuse large B- cell lymphoma （DLBCL） to establish the suitable criteria for evaluating posttherapeutic lesions in scans.

METHODSFifty- six newly diagnosed DLBCL patients were enrolled in the study, and underwent baseline, early and interim ¹⁸F- FDG PET/CT scans. Five- point and % ΔSUVmax criteria were used separately to interpret ¹⁸F- FDG PET/CT images. Interobserver reproducibility was assessed with the kappa test（κ）, and thresholds of %ΔSUVmax were calculated via receiver operating characteristic curve（ROC）. Survival curves were obtained using Kaplan-Meier curves and log-rank test. Cox regression analysis was used for multi-factor analysis.

RESULTSMedian follow-up was 24 months（6 to 42 months）. The kappa value of the five- point scale was above 0.600 with the reference background set in the liver（Score≥4）. The optimal threshold of %ΔSUVmax was 81% for early PET/CT and 74% for interim PET/CT. Survival analysis showed both early and interim PET/CT scans could predict the outcome of 56 patients with DLBCL, and 3-year PFS and OS of PET-negative patients were significantly higher than those of PET-positive ones（P<0.05）. Five-score criteria were more accurate in evaluating 3- year PFS of DLBCL patients in the interim PET/CT scan（76.79%）. %ΔSUVmax criteria were better for interpreting 3-year OS（76.79% and 83.93%）. Multi-factor analysis demonstrated that early and interim PET/CT were solid predicting factors for DLBCL patients.

CONCLUSIONEarly and interim PET/CT scans could predict the outcome of patients with DLBCL, treated with R-CHOP/CHOP. Three-year OS was more accurate in early and interim PET/CT using 66 %ΔSUVmax criteria as an interpretation, while 3-year PFS was more accurate in interim PET/CT by five scores criteria.
