A Case of Tofacitinib-Induced Lymphomatoid Papulosis With Ocular Involvement.

Am J Dermatopathol 2022 May 3. Epub 2022 May 3.

Department of Dermatology, Oregon Health and Science University, Portland, OR.

Abstract: Janus kinase (JAK) inhibitors are being prescribed with increasing regularity in dermatology. We report on a patient who initiated treatment with tofacitinib for refractory erythema elevatum diutinum and subsequently developed a novel cutaneous outbreak characterized by firm violaceous papules on the trunk and extremities along with conjunctival injection and periorbital inflammation. Biopsy of affected tissue from both the cutaneous and ophthalmologic sources demonstrated increased numbers of CD30+ large atypical cells amid a mixed inflammatory cell infiltrate, consistent with lymphomatoid papulosis.

Diagnostic Value of Plasmacytoid Dendritic Cells in Differentiating Pityriasis Lichenoides et Varioliformis Acuta From Lymphomatoid Papulosis.

Am J Dermatopathol 2022 Mar;44(3):174-178

Section of Dermatopathology, Department of Dermatology, Boston University School of Medicine, Boston, MA; and.

Abstract: Pityriasis lichenoides et varioliformis acuta (PLEVA) and lymphomatoid papulosis (LyP) can often demonstrate clinical and histopathologic overlap. A recent study demonstrated significant plasmacytoid dendritic cell (pDC) recruitment in lesions of PLEVA, whereas another study reported minimal pDC recruitment in lesions of LyP. To confirm the possible diagnostic value of pDCs in differentiating PLEVA and LyP, we compared the presence and distribution of pDCs and myxovirus protein A (MxA) expression (an indirect assessment of pDC activity).

Genomic Analysis of Cutaneous CD30-Positive Lymphoproliferative Disorders.

JID Innov 2022 Jan 15;2(1):100068. Epub 2021 Nov 15.

Department of Pathology, City of Hope National Medical Center, Duarte, California, USA.

Primary cutaneous CD30 T-cell lymphoproliferative disorders are the second most common cutaneous lymphomas. According to the World Health Organization, CD30 T-cell lymphoproliferative disorders include primary cutaneous anaplastic large cell lymphoma (C-ALCL) and lymphomatoid papulosis (LyP) as well as borderline lesions. C-ALCL and LyP are thought to represent two ends of a spectrum of diseases that have different clinical presentations, clinical courses, and prognoses in their classic forms but share the same histology of medium to large CD30 atypical lymphoid cell infiltrates.

Oncogenic Mutations and Gene Fusions in CD30-Positive Lymphoproliferations and Clonally Related Mycosis Fungoides Occurring in the Same Patients.

JID Innov 2021 Sep 15;1(3):100034. Epub 2021 Jun 15.

Comprehensive Cancer Center Mainfranken, University of Würzburg, Würzburg, Germany.

The emergence of a common progenitor cell has been postulated for the association of CD30-positive lymphoproliferative disease (LPD) and mycosis fungoides (MF) within the same patient. Up to now, no comprehensive analysis has yet addressed the genetic profiles of such concurrent lymphoma subtypes. We aimed to delineate the molecular alterations of clonally related CD30-positive LPD and MF occurring in the same two patients. Read More

Two Histologic Patterns of Lymphomatoid Papulosis Occurring in a Child: A Matter of Timing?

J Pediatr Hematol Oncol 2022 Apr;44(3):e775-e778

Dermatology Service, KK Women's & Children's Hospital, Singapore, Singapore.

There are several histologic patterns seen in lymphomatoid papulosis, with the possibility of different subtypes occurring in the same patient. We report a case of lymphomatoid papulosis presenting with 2 histologic subtypes (types A and B) occurring concomitantly in a 10-year-old child, and postulate that the different subtypes occur dependent on the age of the lesion biopsied. Incidentally, one of the biopsies also shows a rarely seen pattern of pseudoepitheliomatous hyperplasia in a pediatric lymphomatoid papulosis patient. Read More

Primary Cutaneous Gamma-Delta T Cell Lymphomas: A Case Series and Overview of the Literature.

Dermatopathology (Basel) 2021 Nov 17;8(4):515-524. Epub 2021 Nov 17.

UOC Dermatologia, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico, 20122 Milan, Italy.

Primary cutaneous gamma-delta T cell lymphomas (PCGDTCLs) are rare and aggressive cutaneous malignancies that have been diagnostically challenging for dermopathologists and clinicians since their first published descriptions in 1991. Since then, the availability of immunostaining for T cell receptors γ and δ in formalin-fixed paraffin-embedded samples has greatly increased our knowledge of the gamma-delta phenotype by showing that it may also be present in the context of indolent entities, such as mycosis fungoides (MFs) and lymphomatoid papulosis, and this has raised questions concerning its diagnostic and prognostic implications. We here describe the histological and clinical differences between the dermo-epidermal and subcutaneous sub-groups of PCGDTCL observed in a cohort of 20 patients attending a single experienced centre, with particular focus on cases with an MF-like presentation, which are still less well defined than those of classic MF.

Patch/plaque mycosis-fungoides-like presentations of DUSP22-translocated T-cell lymphomas.

J Cutan Pathol 2022 Mar 7;49(3):299-305. Epub 2021 Nov 7.

Department of Dermatology, University of Michigan, Ann Arbor, Michigan, USA.

The DUSP22-IRF4 gene rearrangement results in downregulation of DUSP22, a presumed tumor suppressor in T-cell lymphomagenesis. It has been described in some cases of primary cutaneous and systemic anaplastic large-cell lymphoma, lymphomatoid papulosis, and transformed mycosis fungoides. Here we describe two patients with clinical lesions resembling patch/plaque mycosis fungoides that did not meet WHO criteria for large-cell transformation on histopathology yet showed a DUSP22 translocation.

Pseudomalignancies in Children: Histological Clues, and Pitfalls to Be Avoided.

Dermatopathology (Basel) 2021 Aug 14;8(3):376-389. Epub 2021 Aug 14.

Department of Pathology, Hôpital Necker-Enfants Malades, APHP, 75015 Paris, France.

The term "pseudomalignancy" covers a large, heterogenous group of diseases characterized by a benign cellular proliferation, hyperplasia, or infiltrate that resembles a true malignancy clinically or histologically. Here, we (i) provide a non-exhaustive review of several inflammatory skin diseases and benign skin proliferations that can mimic a malignant neoplasm in children, (ii) give pathologists some helpful clues to guide their diagnosis, and (iii) highlight pitfalls to be avoided. The observation of clinical-pathological correlations is often important in this situation and can sometimes be the only means (along with careful monitoring of the disease's clinical course) of reaching a firm diagnosis.
