A case of cutaneous pseudolymphoma with a distinctive appearance treated successfully by intralesional interferon alpha-1b and corticosteroids.

Dermatol Ther 2020 Apr 16:e13410. Epub 2020 Apr 16.

Department of Dermatology, West China Hospital, Sichuan University, Chengdu, Sichuan, China.

Cutaneous pseudolymphoma (CPL) encompasses various forms of benign lymphocytic proliferative dermatoses that mimic the clinical and/or pathological changes of lymphoma. The clinical manifestations of CPL vary due to differences in the pathogenesis, and accordingly, no specific treatment has been identified. Here, we report a case of CPL on the nose, which had a distinctive appearance and was treated successfully using a combination of intralesional interferon alpha-1b and compound betamethasone (betamethasone sodium phosphate and betamethasone dipropionate).

Cutaneous Pseudolymphoma Secondary to Facial Thread Lift Procedure.

Indian Dermatol Online J 2019 May-Jun;10(3):322-324

Department of Dermatology and Venereology, Hinduhridaysamrat Balasaheb Thackeray Medical College, Dr. RN Cooper Hospital, Mumbai, Maharashtra, India.

Pseudolymphoma, refers to a heterogeneous group of benign reactive T-cell or B-cell lymphoproliferative processes of diverse causes that simulate cutaneous lymphomas clinically and/or histologically. Thread lift involves the elevation of sagging tissues for rejuvenating the face, which loses its elasticity and volume as one ages, by stimulating the production of new collagen and elastin. The incidence of complications with thread lift is comparatively low, like small ecchymosis, mild erythema, mild transitory hyperesthesia, and mild postoperative tumefaction. Read More

1st Department of Dermatology "Andreas Syggros" Hospital, Medical School, National and Kapodistrian University of Athens, Athens, Greece.

Although anti-TNFα agents have revolutionized the treatment of many inflammatory diseases, various concerns have been reported regarding the risks of cancer development, as well as acceleration of the progression of subclinical, preexisting malignancies. In this case series, we investigated the provocative effect of anti-TNFα drugs in the development of cutaneous mycosis fungoides (MF)-like lymphoproliferative reactions. We describe five patients aged between 25-63 diagnosed with autoimmune disorders (psoriatic arthritis - one patient, Crohn's disease - one patient and ankylosing spondylitis - three patients) who received anti-TNFα agents before the development of a cutaneous lymphoproliferative reaction.

Primary cutaneous lymphomas are a heterogeneous group that includes 2 main groups of primary T- and B-cell lymphomas, which can involve the skin with distinct variability in clinical presentation, histopathology, immunophenotypes, molecular signature, and prognosis. The authors describe the most frequent clinical forms of cutaneous lymphomas and their dermoscopic features. Even if the diagnosis of these entities is still based on a cellular level and the literature on dermoscopy in cutaneous lymphomas is limited and, for several entities it is based only on single case reports/case series, we think that know how they appear also in dermoscopy can be useful for helping in the clinical diagnosis.

Approach to dermal-based lymphoid infiltrates and proliferations.

Semin Cutan Med Surg 2018 Mar;37(1):61-74

Department of Pathology, The American British Cowdray Medical Center, Mexico City, Mexico.

The histopathological diagnosis of dermal-based lymphoid infiltrates and proliferations is often challenging due to the vast list of biologically diverse entities that archetypally or occasionally center in the mid-dermis, especially because significant overlap exists in their clinical, histopathologic, and immunophenotypic features. The differential diagnosis includes reactive infiltrates in common and rare inflammatory dermatoses, benign conditions that may mimic lymphoid neoplasms (pseudolymphomas), and true clonal proliferations arising either primarily in the skin or rarely in extracutaneous tissues with secondary cutaneous dissemination. While numerous histopathological and immunophenotypic features have been reported to support a definitive diagnosis, no single ancillary test is sufficient for their distinction. Read More

Comprehensive Cancer Center Mainfranken, University of Würzburg, Würzburg, Germany; Department of Dermatology, Venereology and Allergology and Skin Cancer Center, University Hospital Würzburg, Würzburg, Germany.

Primary cutaneous marginal zone lymphoma (PCMZL) represents an indolent subtype of non-Hodgkin lymphoma that is clinically characterized by slowly growing skin tumors with a very low propensity for systemic dissemination. The underlying genetic basis of PCMZL has not been comprehensively elucidated. To gain deeper insight into the molecular pathogenesis of PCMZL, we performed hybridization-based panel sequencing of 38 patients with well-characterized PCMZL. Read More

Drug induced pseudolymphoma.

Semin Diagn Pathol 2018 Jul 1;35(4):247-259. Epub 2018 Feb 1.

Regional Medical Laboratory, 4142 South Mingo Road, Tulsa, OK 74146-3632, United States.

Atypical lymphocytic infiltrates of the skin comprise a broad spectrum of entities ranging from benign infiltrates to those that are malignant. Many of these infiltrates are in fact reactive lymphomatoid ones related to drug therapy falling under the general category of drug associated pseudolymphoma. Within this nosologic umbrella are nodular and diffuse infiltrates resembling low grade T and B cell lymphoma consistent with lymphocytoma cutis, drug associated reversible T cell dyscrasias which draw a strong morphologic and phenotypic parallel with mycosis fungoides and the various pre-lymphomatous T cell dyscrasias, and angiocentric CD30 positive infiltrates mirroring lymphomatoid papulosis.

Syphilis is a resurging sexually transmitted infection linked to Treponema Pallidum. Syphilitic lymphadenitis can be present during the 3 stages of the disease. Its histological diagnosis remains challenging for the pathologist given its possible misleading aspect and its ability to mimic as well as reactional as tumoral conditions. Read More

Areolar lymphocytoma in a child: A rare cutaneous presentation of borreliosis.

Pediatr Dermatol 2018 Jan 4;35(1):e90-e91. Epub 2017 Dec 4.

Division of Dermatology, Department of Pediatrics, School of Medicine, University of Washington and Seattle Children's Hospital, Seattle, WA, USA.

Lyme disease is a common tick-borne infection caused by Borrelia burgdorferi in the United States, where infection is most prevalent in the northeastern and mid-Atlantic states. Although classically associated with erythema migrans, Lyme disease caused by Borrelia species found in Europe may also present with other cutaneous findings. Here we report the case of a girl who was clinically diagnosed with Lyme disease based on her history of recent travel and the appearance of an areolar lymphocytoma; this was confirmed by testing.

Red tattoo-related mycosis fungoides-like CD8+ pseudolymphoma.

J Cutan Pathol 2018 Mar 27;45(3):226-228. Epub 2017 Dec 27.

Department of Dermatology, Mayo Clinic, Rochester, Minnesota.

Cutaneous reactions to red tattoo pigment rarely manifest as pseudolymphomatous reactions. We describe an exceedingly rare case of red tattoo-related T-cell predominant pseudolymphoma microscopically mimicking mycosis fungoides. Careful clinicopathological correlation was required to obtain the correct diagnosis and aid in an effective treatment course. Read More

Acta Derm Venereol 2018 Mar;98(3):310-317

Department of Dermatology, Jena University Hospital Erfurter Straße 35, DE-07743 Jena, Germany.

Cutaneous pseudolymphoma (CPL) is a reactive polyclonal T- or B-cell lymphoproliferative process. CPL may appear as localized or disseminated skin lesions. While most cases of CPL are idiopathic, they may also occur as a response to, for example, contact dermatitis, arthropod reactions, and bacterial infections. Read More
