Atypical lymphocytic lobular panniculitis: a clonal subcutaneous T‐cell dyscrasia

Abstract

ALLP represents a form of cutaneous lymphoid dyscrasia given the relatively self-limited nature of the eruption, albeit in the context of clinical recurrence.

Indolent Primary Cutaneous γ/δ T-Cell Lymphoma Localized to the Subcutaneous Panniculus and Its Association With Atypical Lymphocytic Lobular Panniculitis

“…Clinical and histologic overlap is noted with enigmatic conditions such as LEP, ALLP, Weber-Christian disease, and histiocytic cytophagic panniculitis. [13][14][15][16][17][18] Among the many similarities to LEP are a reproducible tendency to involve the proximal aspect of the extremities or trunk; exacerbation during pregnancy; accompanying systemic connective tissue disease symptoms, such as fever, anorexia, and leukopenia; and a baseline histologic pattern of lymphocytic lobular panniculitis. Some cases of panniculitis-like T-cell lymphoma have sufficient clinical and morphologic overlap with LEP that they are initially diagnosed as such.…”

World Health Organization–European Organization for Research and Treatment of Cancer classification of cutaneous lymphoma in Korea: A retrospective study at a single tertiary institution

“…When this disease involves the extremities, the clinical manifestation and histologic features are similar to those of extranodal NK-/T-cell lymphoma and lupus erythematous panniculitis. 22,23 Clinicians have to investigate the immunohistochemical study carefully. One of our patients with SPTL had been given a diagnosis of lupus panniculitis according to skin biopsy specimen results; however, several years later, the diagnosis of SPTL was confirmed based on the last skin biopsy specimen.…”

Lymphome T sous-cutané à type de panniculite

“…La panniculite lobulaire lymphocytaire atypique (PLLA) a été décrite par Magro et al [57,58] à propos de 16 patients. La clinique, l'infiltrat lymphohistiocytaire atypique lobulaire et la présence d'un réarran-gement clonal du TCR sont des éléments communs aux PLLA et aux LTSP.…”
