Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently described form of T-cell non-Hodgkin lymphoma now formally recognized by the World Health Organization classification of lymphoid neoplasms. The aim of this paper is to report the first case of BIA-ALCL diagnosed in a pregnant patient. It is well known that BIA-ALCL appears as an indolent lymphoma with a good prognosis when diag-nosed at early stages and clinical guidelines for its management have been clearly published. Nevertheless, they lack a standardized approach for BIA-ALCL during pregnancy. With limited experience in our case, treatment has been safely postponed after term without affecting patient's overall prognosis and without fetal complication. The fact that the disease was diagnosed at an early stage (stage I) undoubtedly influenced the course of treatment. A multidisciplinary approach weighing the risks and benefits of treatment is of paramount importance in order to ensure the best possible outcome for both the mother and her child and clinical update guidelines should be issued.

The present investigation was under taken to study whether the tumor-associated macrophages (TAM) of Daltons lymphoma (DL), a spontaneous transplantable murine T cell lymphoma can be activated to tumoricidal state by crude thymus extract. Intraperitoneal administration of thymus extract to DL-bearing mice resulted in activation of TAM with an enhanced IL-1, TNF and antigen presenting ability. It was found that treatment with thymus extract could also enhance the phagocytic and cytotoxic activity of TAM. However, only a marginal increase in arginase activity was observed. Till date to the best of our knowledge the effect of crude thymus extract on the activation of tumor associated macrophages has not been investigated, this study provides a new piece of information in the area of thymus therapy.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently spotlighted T-cell origin non-Hodgkin's lymphoma with an increasing incidence of over 800 cases and 33 deaths reported worldwide. Development of BIA-ALCL is likely a complex process involving many factors, such as the textured implant surface, bacterial biofilm growth, immune response, and patient genetics. As the incidence of BIA-ALCL is expected to increase, it is important for all surgeons and physicians to be aware of this disease entity and acquire thorough knowledge of current evidence-based guidelines and recommendations. Early detection, accurate diagnosis, and appropriate treatment are the foundations of current care.

Background: Non-Hodgkin's lymphoma (NHL) patients demonstrate multiple symptoms in diagnosis and treatment processes. This cross-sectional descriptive study aimed to determine the symptoms and symptom clusters in such patients receiving chemotherapy. Materials and Methods: The study was carried out on a total of 110 inpatients and outpatients receiving treatment in 7 hospitals in Ankara, Turkey. A questionnaire form and the Memorial Symptom Assessment Scale (MSAS) were applied. Percentages, means, t test, one way analysis of variance (ANOVA) and cluster analysis were used for statistical analyses. Results: The most prevalent symptoms in this study were lack of energy, hair loss and change in the way food tastes. The most severe symptoms were hair loss, change in the way food tastes and constipation. The top three most distressing symptoms were taste change, constipation and mouth sores. Seven symptom clusters were determined in this study. Conclusions: Findings of the study will provide an understanding of symptom experiences of Non-Hodgkin's lymphoma patients receiving chemotherapy and will guide determining appropriate nursing interventions. Receiving care of desired quality will contribute to increasing quality of life of affected individuals.

Anaplastic large cell lymphoma (ALCLs) are a group CD30-positive mature T-cell lymphomas, an uncommon subtype of non-Hodgkin lymphomas, characterized by diverse clinical and genetic features. Among the types of ALCL, anaplastic lymphoma kinase (ALK)-negative ALCL, though typically involves the lymph nodes, can infrequently invade other tissues. When soft tissue involvement occurs, it may mimic the clinical presentation of infectious diseases, leading to potential misdiagnosis. Therefore, a histological examination is necessary to differentiate between ALK-negative ALCL and similar phenotypes associated with infectious conditions. This paper reports a case of ALCL, initially misdiagnosed as an infection.

A 5-year-old, spayed female Maltese dog presented with generalized multifocal pruritic erythema and alopecia for a month. Initial skin biopsy suggested cutaneious histiocytosis. The dog had been treated with the immunosuppressive therapy for a month, but multifocal erythematous patches and plaques were newly observed. Direct imprint smear of cutaneous lesions suggested a lymphoma and rebiopsy was performed. Microscopic examination demonstrated a round cell tumor with epitheliotrophism to the epidermis and adnexal structures. The neoplastic round cells were strongly positive for CD3 yet negative for CD79a, indicting the tumor was cutaneous epitheliotropic T-cell lymphoma. After 2 cycles of oral administration of lomustine ($70mg/m^2$, once every 2-3 weeks), only partial response was observed. Alternative chemotherapy with gemcitabine ($500mg/m^2$, 30-minute IV infusion, once every week) was initiated. A total 3 cycles of gemcitabine failed to control the progression of disease, and the dog was euthanized on Day 69 after the 1st lomustine treatment.

An 11 year-old male Korean short-haired cat was presented to local animal hospital due to weight loss, vomiting, and intestinal hypomotility. After the cat was euthanized by poor clinical outcomes, necropsy was performed at Animal and Plant Quarantine Agency. At necropsy, the stomach was enlarged and had some nearly complete pellet food and the yellow mucous contents. The lumen of the middle and lower parts of the jejunum became narrow. Histopathologically, medium-sized lymphoid cells with hyperchromatic nuclei enclosed by scant cytoplasm were diffusely proliferated from mucosa to serosa of the small intestine. These findings were mainly observed in the jejunum and slightly in the duodenum and ileum. The monomorphous lymphocytes were 1 to 1.5 times larger than red blood cells and had few mitotic figures. Metastasis of the tumor cells to other organs was not observed. In the result of immunohistochemical analysis for identifying the origin of tumor cells, CD3 was expressed, but $CD79{\alpha}$ was not detected in the infiltrated cells. This case was diagnosed as T cell intestinal lymphoma in a Korean short-haired cat based on the clinical signs, gross findings, histopathology, and immunohistochemistry.

Background: Scid.adh is a recently developed murine thymic lymphoma cell line, which has been used as in vitro model for the study of double negative stage III thymocytes. In this study, we compared the expression profile of a number of genes and proteins, which are tightly related to T cell development and apoptosis, in thymic lymphoma cell lines, R1.1, EL-4, and Scid.adh for the developmental staging. Methods: We examined the expression of development marker genes and proteins in three lymphoma cell lines by flow cytometry and RT-PCR. In addition, the expression of apoptosis-related molecules including bcl-2, bax and Fas was also investigated. Results: As previously reported, Scid.adh cell line expressed CD8 and CD25 but not TCR ${\alpha}$ chain, while R1.1 cells expressed TCR ${\alpha}$ chain and both CD4 and CD8 transcripts. These suggest that R1.1 might be in double positive stage, and low level of CD44 expression and the absence of CD25 support this suggestion. In contrast, EL-4 cells showed high level of TCR ${\alpha}$ chain transcript, and low-level of CD4 expression, suggesting that EL-4 is in more mature stage than R1.1. Further, this suggestion was supported by the lack of mT-20 in EL-4 cells, which is expressed in the immature thymocytes, and Scid.adh and R1.1 cell lines, but not in the terminally differentiated thymocytes and peripheral T cells. Among the apoptosis-related gene, transcripts of bcl-2 gene were detected in both R1.1 and EL-4 but not in Scid.adh cells, while bax was expressed in all cell lines. Fas expression was the highest in EL-4 cells and low in Scid.adh cell line. Conclusion: R1.1 cell may represent double positive stage, and EL-4 is more differentiated cell line. In addition, Scid.adh and EL-4 cell lines are suspected to be useful for the study of function of bcl-2 family and Fas during the thymocyte development, respectively.
