#1
Alejandro A Gru, Andrea L Salavaggione
The terms 'lichenoid' and 'interface' dermatitis are often used interchangeably to describe an inflammatory pattern characterized histologically by damage to the basal keratinocytes in the epidermis. The mechanism of cell damage of such cells is now best understood as apoptosis, or programmed cell death. This inflammatory pattern of dermatoses, is also accompanied frequently by a band of lymphocytes and histiocytes in the superficial dermis, that often obscures the dermal-epidermal junction, hence the term 'lichenoid'...

Alejandro A Gru, Andrea L Salavaggione
This review article focuses on the spongiotic tissue reaction pattern and some of the common entities that practicing pathologists can frequently encounter in their practice. The spongiotic tissue reaction pattern is the single most common one encountered in the routine analysis of inflammatory dermatoses, and the most non-specific one as well. Spongiotic dermatoses include a very large list of disorders which are best grouped under neutrophilic, eosinophilic, miliarial, follicular and pityriasiform forms of spogiosis...

Hepatocellular carcinoma and intrahepatic cholangiocarcinoma are two distinct forms of primary liver carcinoma recognizable at the microscope by their architectural and cytological characteristics, as well as specific immunohistochemical profiles. This straightforward concept however, is increasing imperiled by the recognition of primary liver carcinomas that do not subscribe to a dichotomous paradigm of differentiation, and instead demonstrate biphenotypic differentiation, stem/progenitor cell like features or other variant patterns of differentiation...

Divya Sharma, Girish Subbarao, Romil Saxena
Hepatoblastoma is the most common primary malignant hepatic tumor of infancy and childhood, occurring predominantly in the first two years of life. The management of hepatoblastoma has changed markedly over the last 3 decades; neoadjuvant chemotherapy is now standard, particularly in unresectable tumors resulting in considerable preoperative tumor shrinkage and sometimes near total ablation of the tumor. A 20 month old infant was incidentally found to have a 7.6cm right sided retroperitoneal tumor on routine screening ultrasonography for left ureteral stenosis...

Rondell P Graham, Michael S Torbenson
Fibrolamellar carcinoma is a unique type of hepatocellular carcinoma with a distinctive predilection for young patients without underlying liver disease, characteristic large neoplastic cells with intervening, dense fibrosis, co-expression of keratin 7 and CD68 and activation of protein kinase A (most often by formation of DNAJB1-PRKACA). Fibrolamellar carcinoma has a similar prognosis to conventional hepatocellular carcinomas arising in non-cirrhotic livers. The current American Joint Cancer Committee staging system does not provide optimal stratification of patients with fibrolamellar carcinoma and an alternate systems should be considered in the future...

Cholangiocarcinoma, also referred to as cholangiocellular carcinoma (particularly in Japan), develops along the biliary tract. The tumor may be intra- or extrahepatic and have different features with specific treatments based on the site of origin. Guidelines for diagnosis and management of cholangiorcarcinoma, such as those proposed by EASL (European Association for the Study of the Liver)(1) and the Mayo Clinic(2) classify the tumor into intrahepatic, perihilar, and distal cholangiocarcinoma. There are three main macroscopic patterns of growth of cholangiocarcinoma: mass-forming, periductal-infiltrating and intraductal...

Jacqueline M Junkins-Hopkins Md
Cutaneous T cell lymphomas (CTCLs) are heterogeneous, with a prognosis determined in large part by combined clinical, histopathologic, and immunophenotypic features. They are classified under the WHO-EORTC classification of primary cutaneous lymphoma. Whether or not a patient diagnosed with CTCL will experience an aggressive course may not be completely predictable; however, certain subtypes have been proven to be associated with a poor response to therapy and/or short survival. These aggressive subtypes may be diagnosed by certain histologic, immunophenotypic, and clinical features; however, there are benign lymphoproliferative disorders (LPD), such as lymphomatoid papulosis (LyP) that present with biopsy findings that simulate an aggressive lymphoma...

In this review, we present clinical features and detailed histopathologic, immunologic, and molecular information regarding primary cutaneous follicle center lymphoma and primary cutaneous diffuse large B-cell lymphoma, leg type which together represent two of the three most common types of primary cutaneous B-cell lymphoma recognized in the current WHO classification system.(1,2) Overall, B-cell lymphomas represent 19-27% of primary cutaneous lymphomas in most large European and American studies(3-6) and together, primary cutaneous follicle center lymphoma and primary cutaneous diffuse large B-cell lymphoma, leg type account for approximately 2/3 to ¾ of these cases...

Kojo S J Elenitoba-Johnson, Ryan Wilcox
Mycosis Fungoides (MF) and Sézary Syndrome (SS) are clonal proliferations of mature T-cells manifesting as lymphoproliferative disorders in which the neoplastic cells show a strong propensity for skin-homing. While the predominant site of presentation in MF is the skin, the peripheral blood carries a significant tumor burden in Sézary Syndrome such that it resembles a "leukemic" disease. While the genetic basis of these diseases has been studied using different approaches in the previous years, recent genome-wide studies employing massively parallel sequencing techniques now offer new insights into the molecular pathogenesis of these diseases...

Werner Kempf
Cutaneous CD30+ T-cell lymphoproliferative disorders (CD30+ T-LPD) represent a spectrum encompassing lymphomatoid papulosis (LyP), primary cutaneous anaplastic large-cell lymphoma (pcALCL) and borderline lesions. They share the expression of CD30 as a common phenotypic marker. They differ however in their clinical presentation, the histological features and clinical course. Moreover, LyP and PcALCL show numerous clinical, histological and phenotypic variants. Overlapping features of LyP and pcALCL with themselves and with other cutaneous and systemic lymphomas emphasize the importance of careful clinicopathologic correlation and staging in the diagnosis of CD30+ T-LPD...

This article will focus on the cutaneous lymphoproliferative disorders associated with EBV, with an emphasis on the upcoming changes in the revised 4th Edition of the WHO classification of tumors of the hematopoietic system, many of which deal with cutaneous disorders derived from NK-cells or T-cells. Extranodal NK/T-cell lymphoma usually presents in the upper aerodigestive tract, but can involve the skin secondarily. EBV-associated T- and NK-cell lymphoproliferative disorders (LPD) in the pediatric age group include the systemic diseases, chronic active EBV infection (CAEBV) and systemic EBV+ T-cell lymphoma of childhood...

Primary cutaneous marginal zone lymphoma (CMZL) is one of the major primary B-cell lymphomas of skin. Two types are recognized: a more common class-chain switched CMZL, and a much less common IgM+ CMZL. The extremely indolent course, together with other features distinct from most other MALT lymphomas, has led some to question whether at least the class-switched cases should be considered an overt lymphoma.

Subcutaneous panniculitis-like T-cell lymphoma and primary cutaneous gamma/delta T-cell lymphoma are the two most common types of cutaneous T-cell lymphoma presenting with panniculitis-like lesions. In this article the characteristic clinical, histological and immunophenotypical features of these conditions are reviewed and criteria to differentiate these tumors from other benign and malignant lymphoproliferations presenting with panniculitis-like lesions are discussed.

Primary cutaneous lymphomas represent a broad group of diseases with different clinical, histopathological, phenotypic, molecular, and prognostic features. All cutaneous lymphomas share the same tropism of neoplastic lymphocytes for the skin, but precise classification is paramount for proper management of the patients. Primary cutaneous lymphomas are classified according to the schemes proposed by the European Organization for Research and Treatment of Cancer (EORTC)-Cutaneous Lymphomas Task Force together with the World Health Organization (WHO) in 2005, and the WHO classification of 2008 with the 2016 update...

This review considers neoplastic lesions that originate in the skin, and which have the potential to imitate hematopoietic proliferations at a histological level. They include lymphoepithelioma-like carcinoma, Merkel cell carcinoma, benign lymphadenoma, pseudolymphomatous angiosarcoma, lymphadenoid dermatofibroma, lymphomatoid atypical fibroxanthoma, histiocytoid (epithelioid) hemangioma, and inflamed melanocytic lesions. The clinical and pathological features of those tumors are considered.

Mark R Wick
The diagnosis of panniculitis is felt to be a confusing topic by some pathologists. This summarical article presents inflammatory diseases of the subcutis in a systematic fashion, based on whether they are centered on fibrovascular septa or the adipose lobules, and whether morphologic vasculitis is present or not. Septocentric, non-vasculitis disorders include erythema nodosum, panniculitis that follows the use of "biological" therapeutic agents, lipodermatosclerosis, post-irradiation panniculitis, morphea profunda, and necrobiosis lipodica profunda...
