A review of 55 cases of cutaneous lymphoid hyperplasia: reassessment of the histopathologic findings leading to reclassification of 4 lesions as cutaneous marginal zone lymphoma and 19 as pseudolymphomatous folliculitis

Lymphocytoma cutis - case report

“…The disseminated form is rarer, found mostly in elderly people, affecting the midsection and extremities, in addition to the face. 5-6,8 The clinical condition in which there is dissemination of lesions is termed miliary lymphocytoma cutis. 2,5 …”

A Rare Kind of Lymphoma in a Patient on Treatment With Two Different Biological Agents

“…17 Cutaneous pseudolymphoma refers to a heterogeneous group of benign reactive T-cell and B-cell lymphoproliferative processes of diverse causes, which can simulate cutaneous lymphomas in which the reactive inflammatory infiltrates may occasionally simulate lymphoma. 1,2,18 The common feature of CPL that distinguishes it from other benign inflammatory cell infiltrates in the skin is the presence of variable numbers of medium to large sized lymphocytes, which may appear atypical, alongside many ordinary small lymphocytes and other inflammatory cells. Depending on the cause, this lymphocytic infiltrate may consist particularly of B-or T-cell, in most cases -mixture of B-and T-cells, macrophages and dendritic cells.…”

Light chain restriction confined to lower portions of cutaneous lymphocytic proliferations: a potential diagnostic pitfall

“…It is possible that some lesions initially classified as CLH were lymphomas to begin with. Arai et al, evaluated 55 examples of CLH, of which 4 were reclassified as MZL and one was reclassified as diffuse large B-cell lymphoma 3 . It is possible that a similar misclassification of all three cases presented here might have occurred had the deeper portions of the lesions not been evaluated.…”
