Autoimmune lymphoproliferative syndrome (ALPS) is characterised by massive enlargement of the lymphoid organs, autoimmune cytopenias and a predisposition to develop lymphoid malignancies. The basic defect is a disturbance of the lymphocyte apoptosis, and a high number of circulating TCRab CD3CD4CD8 T-cells (double-negative T cells (DNT cells)). We describe a case of a 41-year-old man with fever, hepatosplenomegaly, multiple lymphadenopathy, autoimmune haemolytic anaemia and severe thrombocytopenia. Peripheral blood immunophenotyping revealed elevation of the characteristic DNT cells in 8% and high levels of interleukin 10. Histopathological analysis of lymph nodes showed lymphadenitis with paracortical hyperplasia. It was assumed as a probable diagnosis of ALPS, and the procedure was to medicate the patient with steroids. As a result, a significant clinical improvement was achieved, and he has been in remission for 2 years. To our knowledge, this is the first case reported in a Portuguese adult patient.

Indolent clonal lymphoid disorders are not recognized as lymphomas as they generally need no systemic treatment, and depending on the lesion, need only limited clinical follow-up. These lesions are usually incidentally diagnosed during the work up for other disease. The recognition of indolent clonal lymphoid disorders is important to avoid misdiagnosis as lymphoma and unnecessary treatment.

Various clinical conditions like autoimmunity, lymphoproliferative/malignant diseases, chronic lung and gastrointestinal system diseases have been identified which accompanies PIDs besides recurrent infections. However, there is a lack of information about accompanying cardiovascular diseases.

Post-transplant lymphoproliferative disorders (PTLD) and lymphomas in immunocompromised individuals represent significant clinical challenges, with a limited understanding of their pathogenesis. We investigated a PTLD cohort (n = 50) consisting of 'early lesions' (infectious mononucleosis-like PTLD, plasmacytic and follicular hyperplasias), polymorphic PTLD and post-transplant diffuse large B-cell lymphomas (PT-DLBCL). The study also included 15 DLBCL with autoimmune/immunocompromised backgrounds (IS-DLBCL) and 14 DLBCL, not otherwise specified (DLBCL, NOS), as control.

Introduction: Although the HaCaT keratinocyte model has been used in previous research to study the effects of antipsoriatic agents, there is still a lack of comprehensive understanding of the mechanism of imiquimod (IMQ)-induced proliferation and signal transduction in psoriasis-like keratinocytes.
Objectives: This study aimed to investigate the molecular mechanisms and pathways associated with psoriasis-like inflammation caused by IMQ in human keratinocytes.
Materials And Methods: HaCaT cells were exposed to different concentrations of IMQ to induce inflammation similar to that observed in psoriasis.

Background: Angioedema (AE) due to acquired C1-inhibitor deficiency (AAE-C1-INH) is a rare disease associating recurrent edema of mucosa and skin. Several underlying diseases have been reported, mainly lymphoproliferative diseases and monoclonal gammopathy. However, 15 to 20% of patients never exhibit such a hematological condition.
