To clarify the clinicopathologic and immunohistochemical features of dermatopathic lymphadenopathy not associated with mycosis fungoides among Japanese, 19 patients were studied. Seventy-four percent of the patients were more than 50 years old (median; 63 years, mean 61 years). Systemic symptoms such as fever were recorded in 68% and multicentric lymphadenopathy was noted in 83% of patients. An association of autoimmune disease or positivity of autoantibodies was recorded in 6 patients. Five patients showed cutaneous hypersensitivity reactions to a drug. Histologically, in addition to the dermatopathic lymphadenopathy, numerous immunoblasts were observed in 2 cases and sheet-like proliferation of mature plasma cells in 3 cases. Various atypical or malignant lymphoproliferative disorders exhibiting immunologic abnormalities such as angioimmunoblastic T-cell lymphoma or autoimmune disease-associated lymphadenopathy frequently occur in middle-aged and elderly patients. At least some of the patients with derm...

There has been a renewed interest in Langerhans cell histiocytosis in recent years due both to advances in basic research and to improvements in diagnostic and treatment approaches. In this article, we review the various aspects of the disease and the potential implications of these recent scientific researches for our understanding and management of the disorder.

Gene rearrangement and monoclonality have been detected in normal cells and in lymphoproliferative disease by using the polymerase chain reaction and primers for the V and J regions of the Ig heavy chain gene or T-cell receptor gamma-chain gene. Using the Ig primers monoclonality was detected in 20 of 20 normal B-lymphocyte clones and in 39 of 52 cases of various types of B-lymphoproliferative disease, but not in 11 cases of T-lymphoproliferative disease. Using the T-cell receptor primers, monoc...

Postthymic (peripheral) T-cell malignancy shows marked diversity in histopathologic appearances as well as in clinical and prognostic aspects. Histologic findings and clinical behavior of 110 cases of the three specific types of low-grade, peripheral T-cell lymphomas, i.e., lymphoepithelioid (LeL), angioimmunoblastic (AILD), and T-zone (TzL) lymphomas, were studied. There were 74 men and 36 women (age range, 24 to 90 years; median, 58). Histologic study of LeL, AILD, and TzL showed prominent rea...

Abstract The lymph nodes from 50 axillary node dissections were evaluated by light microscopy and immunohistochemistry for the presence of dermatopathic lymphadenitis-like histologic features. On the basis of hematoxylin-eosin-stained sections alone, a histologic continuum was observed ranging from minimal paracortical changes to fully developed dermatopathic lymphadenitis. Twenty-three lymph node biopsies previously interpreted as diagnostic of dermatopathic lymphadenitis were reviewed. Only ni...

: Dermatopathic lymphadenopathy (DPL) is characterized by lymph node enlargement with reactive process and is generally caused by chronic inflammatory skin disease. Interdigitating reticulum cells (IDCs) with broad cytoplasm, innumerable cytoplasmic interdigitation, and bizarre shaped nuclei are the most striking cell type in DPL. According to the shape of the nucleus, arrangement of the tubulovesicular complexes (TVC) and amount of melanin granules, these cells fall into two types: type I has a...

Thirty-five patients with dermatopathic lymphadenopathy, 12 with (9 patients and 3 follow-up) and 23 without associated mycosis fungoides, and 7 controls with 26 lymph nodes were studied by light microscopic examination and immunostaining for S-100 protein. Fourteen of these cases were examined ultrastructurally. The group of cases studied included lymph nodes obtained at postmortem examination from three patients with mycosis fungoides and evidence of nodal involvement by light microscopic exam...

Leu-6 is an antigen expressed by immature T cells, Langerhans cells, and indeterminate cells, the latter two of which are dendritic cells found predominantly within the skin. In dermatopathic lymphadenopathy, the paracortex is expanded by T cells and dendritic cells, including Langerhans cells. While the paracortex also contains Leu-6 + cells, the nature of such cells in lymph nodes has been controversial. To determine the characteristics of Leu-6 + paracortical cells, their morphologic, antigen...

Abstract With the use of in situ immunohistochemical techniques on freshly frozen and paraffin-embedded material from 63 reactive lymph nodes, the cellular composition of T-nodules observed in 30 cases with nodular alteration of the paracortical area was analyzed. T-nodules were composed of S-100 beta + interdigitating reticulum cells (IDRCs), variable numbers of OKT6+ dendritic cells (DCs), high endothelial venules, and a very high T helper/T suppressor ratio because of an enrichment of OKT4+, ...

AIMS: Dermatopathic reaction is a histopathological finding of the lymph node that usually occurs in patients with inflammatory pruritic cutaneous lesions. However, it is sometimes seen in patients with cutaneous T-cell lymphoma. Adult T-cell leukemia/lymphoma (ATLL) is a T-cell malignancy caused by infection with human T-cell leukemia virus type I (HTLV-1), frequently accompanied by cutaneous lesions. However, detailed clinicopathological characteristics of dermatopathic reaction of lymph nodes...

Dermatopathic lymphadenopathy is a distinctive form of paracortical lymph node hyperplasia that usually occurs in the setting of chronic dermatologic disorders. The aim of this study is to update our understanding of the clinicopathologic and immunophenotypic features of dermatopathic lymphadenopathy. The study cohort was 50 lymph node samples from 42 patients diagnosed with dermatopathic lymphadenopathy. The patients included 29 women and 13 men with a median age of 49 years (range, 12–79). Twe...

Adult onset Still’s disease (AOSD) is a chronic inflammatory disorder involving multiple systems. The symptoms mimic those of lymphomas, therefore, the diagnosis of lymphoma needs to be excluded prior to establishing the diagnosis of AOSD. Another similar condition is dermatopathic lymphadenopathy (DL). In DL, the histopathological appearance of lymph node biopsy may also mimic AOSD. The DL is associated with several systemic pathologies, such as malignant lymphomas, and rarely AOSD. We present ...

Abstract The presence of axillary enlarged lymph nodes in the follow-up of a woman with a history of breast cancer should always be thoroughly indagated. Dermatopathic lymphadenopathy presents a specific pathologic pattern found within the lymph nodes and is usually associated with cutaneous rashes. Patients with various skin conditions can develop regional lymphadenopathy, which can result in the asymptomatic enlargement of the lymph nodes, especially in the inguinal, axillary and cervical regi...

Dermatopathic lymphadenitis (also known as lipomelanotic reticulosis, or Pautrier–Woringer disease) is a rare type of benign lymphatic hyperplasia associated with a variety of exfoliative or eczematoid type inflammatory erythrodermas. The axillary and inguinal regions are most commonly affected, although occasionally it can present in the head and neck as well. On histologic examination, the affected lymph nodes contain melanin and fat-laden reticular cells. This is a case of a 10-year-old boy w...
