Lymphocytic infiltration

However, since the original description by Jessner and Kanof in [ 1 ], lymphocytic infiltration, the existence of JLI as a distinct disease has been questioned [ 2 ]. The list of disorders that overlap clinically and histologically with Lymphocytic infiltration is vast, indicating that JLI is probably not a separate entity, but rather a clinicopathologic reaction pattern common to different skin diseases [ ]. In the last few decades, significant advancements in the immunopathologic and molecular diagnosis have enabled a specific diagnosis for many of the cases previously labeled as JLI [ ].

Home arrow-right-small-blue Topics A—Z arrow-right-small-blue Jessner lymphocytic infiltrate. Jessner lymphocytic infiltrate is an uncommon skin condition that presents as non- scaly red patches and lumps on the face, neck and upper back. They are usually painless and do not itch. Lesions may go through periods of remission and exacerbation over months or years.

Journal of Translational Medicine volume 11 , Article number: Cite this article. Metrics details. Primary cutaneous lymphomas CLs , characterized by an accumulation of clonal T or B lymphocytes preferentially localized in the skin, have been successfully treated with interferons IFNs which counterbalance the Th2-immunosuppressive state associated with this pathology. For each patient, variation in time of specific lymphocyte populations, defined by immunohistochemical stainings, was assessed in biopsies of injected lesions. The phase I step TG The phase II step TG Cutaneous lymphoma CL , with an incidence of 1 case per , individuals per year, is a group of at least fifteen rare diseases [ 1 ]. CL span a wide array of clinical aspects and histological subtypes which correspond to clonal T or B cells, characterized by their expression of lymphoid cell markers, homing and migrating mainly in the skin [ 2 ]. The atypical cells in the lymphomatoid papulosis types A and C lesions have the same phenotype as the tumor cells in ALCL. The body of information now encompassing this family of diseases has motivated the development and justified the use of numerous treatment modalities such as kinase, methylation or histone acetylation inhibitors, mAbs, rexinoids and photopheresis [ 10 ]. Moreover, this group of diseases has been successfully treated with interferons and cytokines that counterbalance the Th2-skewing [ 12 — 14 ]. IFN-g is the principal cytokine associated with the Th1 phenotype. It acts in a positive feedback loop as it is produced by activated Th1 cells and stimulates differentiation of Th0 cells into Th1 cells while suppressing Th2 differentiation reviewed in [ 15 ]. This has led to the development of alternative delivery systems such as TG, a non-replicating adenovirus type 5 vector containing a human IFN-g cDNA insert under the control of the cytomegalovirus promoter [ 16 ]. Intralesional delivery of human IFN-g-expressing adenovirus allows reaching high local concentrations of this cytokine, as shown by quantitative RT-PCR in 7 out of 9 patients following the first treatment cycle.

The surface of the lesions is non-scaly without evidence of follicular plugging or atrophy. NCBI Bookshelf.

Lymphocytic infiltration

Last updated: November 27, Years published: , , , , , , Lymphocytic infiltrate of Jessner is a rare skin condition that may be characterized by non-cancerous benign buildup of white blood cells, which present as lesions or lumps on the skin. These lesions may be seen on areas including the face, neck, upper extremities, shoulders, and upper back skin most exposed to sunlight. Although the lesions are typically not painful, patients with lymphocytic infiltrate of Jessner may experience itchiness and redness. Presentation can vary, for example, the lesions may remain unchanged for several years and resolve.

When a CR was observed, treatment was stopped and a biopsy was taken noted Cx. Figure 3. The eruptions are erythematous, non-scaly, and can also be annular. In addition, a skin biopsy from a newly formed lesion should be tested in order to rule out other similar conditions including discoid lupus erythematosus DLE and polymorphous light eruption PLE. Jessner lymphocytic infiltration - rare in childhood. Materials and Methods Lymphocytic infiltration was evaluated quantitatively in 20 cases of undifferentiated NPC using light microscopy.

Lymphocytic interstitial pneumonia LIP is lymphocytic infiltration of the alveolar interstitium and air spaces.

Differential Diagnosis Jessner lymphocytic infiltration of the skin JLIS is one of a group of conditions characterized histologically by a lymphocytic infiltrate in the dermis. Anyone you share the following link with will be able to read this content:. The tumor cells were arranged in irregular or moderately well-defined masses in a lymphoid stroma. Bulk Download. Patient 27 at baseline left panels and at C1D16 right panels. As they extend from the perimeter, these lesions form well-defined, smooth, red patches plaques whose diameter may go as far as up to one inch. Polymorphous light eruption. Customize your interests. Some clinical scientists argue that this condition is possibly a subtype of the autoimmune condition known as lupus erythematosus, while others believe that it may have its own class. Statistical methods. Lastly, for patients using medical therapy such as topical steroids and antimalarials, regular follow-up is required to monitor for side-effects like skin atrophy.
