Abstract
To image 4-plex immunofluorescence-stained tissue samples at a low cost with cellular level resolution and sensitivity and dynamic range required to detect lowly and highly abundant targets, here we describe a robust, inexpensive (<$9000), 3D printable portable imaging device (Tissue Imager). The Tissue Imager can immediately be deployed on benchtops for in situ protein detection in tissue samples. Applications for this device are broad, ranging from answering basic biological questions to clinical pathology, where immunofluorescence can detect a larger number of markers than the standard H&E or chromogenic immunohistochemistry (CIH) staining, while the low cost also allows usage in classrooms. After characterizing our platform's specificity and sensitivity, we demonstrate imaging of a 4-plex immunology panel in human cutaneous T-cell lymphoma (CTCL) formalin-fixed paraffin-embedded (FFPE) tissue samples. From those images, positive cells were detected using CellProfiler, a popular open-source software package, for tumor marker profiling. We achieved a performance on par with commercial epifluorescence microscopes that are >10 times more expensive than our Tissue Imager. This device enables rapid immunofluorescence detection in tissue sections at a low cost for scientists and clinicians and can provide students with a hands-on experience to understand engineering and instrumentation. We note that for using the Tissue Imager as a medical device in clinical settings, a comprehensive review and approval processes would be required.

Abstract
Sézary syndrome (SS) is defined by erythroderma and circulating atypical T cells, with or without lymphadenopathy. Recently, Thompson et al. identified a distinct population of SS patients with an atypical presentation: a high blood tumor burden of Sézary cells fulfilling criteria for SS but without fulfilling the criteria for erythroderma at the diagnosis. Here, we report a case of a 49-year-old Japanese man with SS who did not present with erythroderma initially, but exhibited erythematous itchy papules symmetrically located on the legs and arms. We also reviewed reported cases of SS without initial erythroderma. The skin manifestations at diagnosis varied from patches to tumors often seen in mycosis fungoides, and other rarer findings such as excoriation, palmoplantar keratoderma and alopecia. Pruritus was reported in most patients (86%), unlike early mycosis fungoides, and could be the main clue to the diagnosis of SS. Notably, three patients were reported to have presented with papular lesions, similar to our case. Little is known about why skin lesions in SS without erythroderma vary and why these cases did not exhibit erythroderma initially. Attenuated stimulation by colonized Staphylococcus aureus, impairment in recruitment of malignant T cells and suppression of inflammatory response induced by malignant T cells with regulatory phenotype may be associated with skin manifestations. Further studies are necessary to elucidate the etiology of this entity.

Abstract
We report the case of a 41-year-old patient with an aggressive cutaneous T-cell lymphoma (CTCL) initially presenting on histology as lymphocytic vasculitis. On repeated histological examination and by molecular biology work-up, the diagnosis of an unclassifiable CTCL could eventually be established. This atypical poorly differentiated lymphoma was of a CD4+ CD8- CD56- phenotype and followed an unfavourable course. The patient died despite chemo- and immunotherapy 7 months after the first consideration of lymphoma as diagnosis.

Abstract
We report a case of CD30 + primary cutaneous anaplastic large cell lymphoma. The lymphoma cells were shown to express the Epstein-Barr virus (EBV)-encoded small RNAs by in situ hybridization and to have EBV genomes by PCR, whereas no monoclonal band was detected by Southern blot analysis using the EBV terminal repeat probe. These data suggested polyclonal infection by EBV, which provides evidence that EBV plays little part in the pathogenesis of this tumour even in the infected cases.

Roxithromycin downmodulates Th2 chemokine production by keratinocytes and chemokine receptor expression on Th2 cells: its dual inhibitory effects on the ligands and the receptors.

Abstract
Roxithromycin (RXM), an anti-bacterial macrolide, has various immunomodulatory activities. To investigate the ability of RXM to downregulate skin-infiltration of T-lymphocytes, we examined the effects of RXM on keratinocyte production of chemokines and T cell expression of chemokine receptors. Normal human and HaCaT keratinocytes were cultured with RXM and stimulants. RXM at 1 or 10 microM significantly suppressed the production/expression of Th2 chemokines MDC and TARC in these keratinocytes, but the production of IP-10 was not affected. The effect of RXM on T-cell expression of the corresponding chemokine receptors was also tested in Th2-rich peripheral blood lymphocytes. The IL-2-enhanced expression level of Th2 chemokine receptor CCR4 was decreased by RXM at 10 microM, whereas the expression of CXCR3 was unchanged. Thus, RXM downmodulates both the production and receptor expression of Th2 but not Th1 chemokines involved in cutaneous immunity, suggesting its beneficial therapeutic effects on Th2-mediated or allergic skin disorders.
