The term "CD30+ T-cell lymphoproliferative disorders" describes a group of diverse diseases of the skin, subcutaneous tissues and mucosa that range from lesions requiring clinical observation to those necessitating systemic cytotoxic chemotherapy. Careful consideration of both clinical and histopathologic presentation is needed for appropriate diagnosis and treatment. This review will present the current classification of these disorders and potential treatment paradigms. Read More

Background: CD8 lymphomatoid papulosis is frequently indistinguishable histopathologically from primary cutaneous aggressive epidermotropic CD8 T-cell lymphoma except for the expression of CD30. However, absent or weak expression of CD30 has been rarely reported in cases of CD8 LyP.
Objective: We aim to study the clinical and pathologic features of cases of CD8 LyP with no or minimal expression of CD30. Read More

Upper eyelid gold weight implants are an established tool in the symptomatic treatment of lagophthalmos, the inability to close your eyes completely. Complications associated to this procedure are infrequent. When noted, non-infectious inflammatory reactions corresponding to type IV hypersensitivity reactions are resolved with the removal of the implant. Read More

To report the first case of lymphomatoid gastropathy in China, and to demonstrate the clinical characteristics, diagnostic approach, treatment and prognosis in this kind of patients. One patient was diagnosed as lymphomatoid gastropathy at Peking Union Medical College Hospital, and her clinical characteristics, lab data, treatment and follow-up outcomes were reviewed. A case of a 51-year-old female was presented, who underwent esophagogastroduodenoscopy (EGD) due to slight epigastric discomfort. Read More

Large-cell transformation in mycosis fungoides (MF) is usually encountered in tumors and is associated with prognosis worsening. It is defined by the onset of more than 25% of lymphocytes, usually expressing CD30, exceeding 4 times the size of normal lymphocytes, either diffuse or organized in sheets in the dermal infiltrate. Recently, an unusual biphasic pathologic pattern was reported in lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large cell lymphoma (ALCL) which was constantly associated with DUSP22-IRF4 gene rearrangement .

Cutaneous T-cell lymphomas (CTCLs) are a group of non-Hodgkin's lymphomas that present in the skin. In early-stage disease, the course is generally chronic and indolent; however, in advanced stages of disease, therapies rarely provide long-lasting responses, and the only potential curative therapy is allogeneic hematopoietic stem-cell transplantation. This has led to the search for novel targeted therapies to better treat more advanced stages of CTCLs that cannot be controlled by typical treatment regimens. Read More

Aims: Molecular pathways underlying the putative evolution from lymphomatoid papulosis (LyP) to cutaneous anaplastic large cell lymphoma (c-ALCL) and lymph node invasion (LNI) remain elusive.
Methods And Results: To clarify this point, we analyzed nine sequential tumors from the same patient presenting a parallel evolution of LyP (n=3) and c-ALCL (n=1) with LNI (n=1) combined with systemic diffuse large B-cell lymphoma (DLCL) (n=4). Clonality analysis showed a common clonal T-cell origin in the five CD30+ lesions and a common clonal B-cell origin in the four DLCL relapses. Read More

Dear Editor,We present the case of a 40-year old male patient with lymphomatoid papulosis of a waxing and waning course on whom three biopsies were performed during a 14-year period with no change in histopathological or immunophenotypical characteristics. Lymphomatoid papulosis (LP) is a chronic, recurrent, self-healing papulonodular skin eruption with the histopathologic features of a cutaneous T-cell lymphoma but an often benign and indolent clinical course (1). It is designated as a primary, cutaneous, CD30+ lymphoproliferative disorder. Read More

Mycosis fungoides (MF), the most common variant, is characterised by clonal proliferation of skin residing malignant T-cells. Initially appearing with erythematous patches and plaques it follows a chronic course with progression to cutaneous tumours and extracutaneous involvement in some patients. Read More

Cutaneous lymphoproliferative disorders remain a challenging aspect of dermatopathology, in part due to the rarity of the entities and extreme variability in clinical outcomes. Although many of the entities remain unchanged, the approach to some of them has changed in the new 2016 classification scheme of the World Health Organization. Chief among these are Epstein-Barr virus-associated lymphoproliferative disorders such as Epstein-Barr virus-associated mucocutaneous ulcer and hydroa vacciniforme-like lymphoproliferative disorder, primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma, primary cutaneous acral CD8+ T-cell lymphoma, primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder, and breast implant-associated anaplastic large cell lymphoma.

Background: Angiocentric lymph proliferative disorder (ALPD) is a granulomatous lymphoproliferative condition associated with various primary and secondary immunodeficiency states. ALPD is so rare that its prevalence has not been established.

Cutaneous CD30+ T-cell lymphoproliferative disorders (CD30+ LPD) are the second most common form of cutaneous T-cell lymphoma. CD30+ LPD include lymphomatoid papulosis, primary cutaneous anaplastic large-cell lymphoma, and borderline lesions. Despite expression of CD30 by the neoplastic cells as the hallmark of these disorders, they differ in their clinical presentation and histological features as well as the course, the prognosis, and consecutively in the treatment.

Lymphomatoid granulomatosis (LYG) is a rare lymphoproliferative disorder characterized by infiltration of Epstein-Barr virus (EBV)-positive large atypical B-cells in an angiocentric fashion in a mixed inflammatory background. The histologic spectrum of LYG ranges from reactive proliferation to diffuse large B-cell lymphoma according to the number of EBV+ B-cells. It is known that virtually all patients have pulmonary involvement, whereas primary LYG of the other organs has been rarely reported. Read More

Lymphomatoid granulomatosis (LYG) is a rare B-cell lymphoproliferative disorder driven by Esptein-Barr virus (EBV) that most commonly affects the lungs, although extra pulmonary sites like the central nervous system, skin, liver and kidney can also be involved. It is microscopically characterized by an angiocentric and angiodestructive growth pattern, predominantly composed by small T-cells, although a smaller population of atypical large B-cells is considered the true neoplastic component. Oral cavity involvement of LYG has rarely been described and the diagnosis of this neoplasm is very difficult. Read More

The contribution of Epstein-Barr virus (EBV) to the development of specific types of benign lymphoproliferations and malignant lymphomas has been extensively studied since the discovery of the virus over the last 50 years. The importance and better understanding of the EBV-associated lymphoproliferative disorders (LPD) of B, T or natural killer (NK) cell type has resulted in the recognition of new entities like EBV+ mucocutaneous ulcer or the addition of chronic active EBV (CAEBV) infection in the revised 2016 World Health Organization (WHO) lymphoma classification. In this article, we review the definitions, morphology, pathogenesis, and evolving concepts of the various EBV-associated disorders including EBV+ diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS), EBV+ mucocutaneous ulcer, DLBCL associated with chronic inflammation, fibrin-associated DLBCL, lymphomatoid granulomatosis, the EBV+ T and NK-cell LPD of childhood, aggressive NK leukaemia, extranodal NK/T-cell lymphoma, nasal type, and the new provisional entity of primary EBV+ nodal T- or NK-cell lymphoma.

Cutaneous CD30 lymphoproliferative disorders (LPDs), including lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large-cell lymphoma, comprise the second most common group of cutaneous T-cell lymphomas. Previously, we reported that special SATB1, a thymocyte-specific chromatin organizer, was overexpressed and promoted malignant T-cell proliferation in a portion of CD30 LPDs. Here, we investigated the expression pattern of SATB1 in CD30 LPDs with a large cohort of patient samples, and examined the potential of SATB1 as a molecular marker to classify CD30 LPDs with differential clinicopathological behaviors.
