Lymphoblastic lymphoma presenting in cutaneous websites: a clinicopathologic analysis of six circumstances. Although "pseudolymphoma" is normally considered as a synonym of a benign condition, some nonlymphoid malignant tumors may also simulate the picture of a cutaneous lymphoma (see the section on "malignant" pseudolymphomas on this chapter). Reading the pertinent literature one will get the impression that the variety of cutaneous "pseudolymphomas" increases often. Some of the printed cases represent reactive conditions that in uncommon exceptions could simulate histopathologically a cutaneous lymphoma, normally mycosis fungoides. In this context, it have to be underlined that true "progression" from a clearcut cutaneous pseudolymphoma right into a malignant lymphoma of the pores and skin is exceptionally uncommon. Cutaneous pseudolymphomas associated with infectious organisms (such as Borrelia burgdorferirelated lymphocytoma) generally arise in regions with endemic an infection for the accountable organisms. On the opposite hand, there was an increase within the variety of instances of Borrelia lymphocytoma in nations where Borrelia species are absent, in sufferers returning from travels in endemic regions. The lesions are often solitary or regionally clustered however can also be generalized in distribution, and even erythroderma may be observed. The lesions might persist for weeks, months, and even years; they could resolve spontaneously, and so they may recur unpredictably. Histologic standards for the diagnosis of cutaneous pseudolymphomas embrace two main options: (i) the architectural pattern of the infiltrates and (ii) the mobile composition of those infiltrates, which incessantly show a mixed character. These histologic options need to be built-in rigorously with the immunophenotypical information. Although, as a rule, malignant lymphomas reveal a monoclonal inhabitants of lymphocytes whereas pseudolymphomas present a polyclonal infiltrate, it should be underlined that demonstration of monoclonality may be lacking in true malignant lymphomas and that a distinct proportion of cutaneous pseudolymphomas harbor a monoclonal T or Bcell inhabitants. In addition, pseudoclonality represents a pitfall in cutaneous infiltrates, significantly when results are interpreted with out information of other data [1]. Although highthroughput sequencing may be more delicate for analysis of clonal populations of T lymphocytes [2�4], knowledge on reactive cutaneous conditions are nonetheless lacking; thus specificity has not but been examined adequately. In this context, it have to be clearly acknowledged that differentiation of benign from malignant lymphoid infiltrates of the skin is possible solely after cautious synthesis and integration of the clinical, histopathologic, immunophenotypical, and molecular features. It is necessary to not overdiagnose cutaneous malignant lymphomas, and in some unclear cases a descriptive time period such as "cutaneous atypical lymphoid proliferation" could additionally be a useful working diagnosis for unclear instances (see Chapter 29). Cutaneous pseudolymphomas are traditionally divided into T and Bcell variants according to the histopathologic and immunophenotypical options, but in plenty of situations this distinction is artificial. In addition, in lots of instances, each T and B lymphocytes are current inside the infiltrate of a given pseudolymphoma. Thus, in what follows cutaneous pseudolymphomas shall be categorised in accordance with particular clinicopathologic entities (Table 28. In addition, the illness is doubtless one of the rarest among the pseudolymphomas; thus the prognosis ought to be made only when compelling proof is present and may be accepted solely when confirmed by pathologic phototesting. Actinic reticuloid is a extreme persistent photodermatitis that normally affects older males. A "leonine" face with deep furrowing of markedly thickened pores and skin as properly as diffuse alopecia can additionally be seen. When present, the features of lichen simplex chronicus superimposed upon an inflammatory course of are helpful in distinguishing actinic reticuloid from mycosis fungoides and S�zary syndrome. The scientific differentiation of actinic reticuloid from mycosis fungoides and S�zary syndrome may be troublesome because circulating cerebriform lymphocytes could additionally be discovered in the peripheral blood of sufferers with actinic reticuloid [11]. Thelper lymphocytes are invariably predominating in S�zary syndrome, whereas Tcytotoxic cells are numerous in actinic reticuloid. Erythematous, scaly, lichenified lesions with scratching artifacts on the arm and again of hand. Suberythroderma inflicting full involvement of the face by erythematous, scaly lesions. In sufferers with actinic reticuloid, the minimal erythema dose is decrease than normal. Treatment of continual actinic dermatitis is difficult and numerous therapeutic approaches have been proposed [13].
