Differential diagnoses of pseudolymphomatous folliculitis: considerations as regards one case.

BMJ Case Rep 2021 Apr 28;14(4). Epub 2021 Apr 28.

Division of Population Health, Health Services Research & Primary Care, Faculty of Biology, Medicine & Health, University of Manchester, Manchester, UK

Pseudolymphomatous folliculitis (PLF) is a rare disease of cutaneous lymphoid hyperplasia, with a low index of clinical suspicion. We present the clinical case of a 19-year-old male patient, with a solitary violet erythematous nodule of 6 months of evolution, located in the right infraorbital region, without presenting another symptomatology. Histopathological examination showed a lymphocytic infiltrate that surrounds the hair follicles, sebaceous and sweat glands that focally destroy their basement membrane. Read More

Hautarzt 2021 Apr 21. Epub 2021 Apr 21.

Hautklinik, Universität Heidelberg, Im Neuenheimer Feld 440, 69120, Heidelberg, Deutschland.

The term cutaneous pseudolymphoma (C-PSL) is defined in the literature as a benign, reactive lymphoproliferation that clinically and/or histopathologically imitates cutaneous lymphoma. The exact etiopathogenesis has not been fully elucidated to date. A distinction is made between primary, idiopathic PSL without an identifiable cause and secondary PSL with a known stimulus.

Wake Forest University School of Medicine, Department of Dermatology, Winston-Salem, North Carolina, USA. Electronic address:

Cutaneous manifestations of drug reactions are common yet vary widely in their appearance and degree of internal organ involvement. Serum sickness--like reactions, symmetrical drug-related intertriginous and flexural exanthem, granulomatous drug eruption, pseudolymphoma, and drug-induced lupus are medication-induced conditions with dermatologic presentations. Many of the conditions discussed are relatively rare but nonetheless demand our attention and understanding. Read More

Helicobacter pylori and skin disorders: a comprehensive review of the available literature.

Eur Rev Med Pharmacol Sci 2020 12;24(23):12267-12287

Department of Biomedical, Dental, Morphological and Functional Imaging Sciences, University of Messina, Messina, Italy.

Helicobacter pylori is a Gram-negative bacterium identified for the first time about 30 years ago and commonly considered as the main pathogenic factor of gastritis and peptic ulcer. Since then, it was found to be associated with several gastrointestinal and extra-gastrointestinal diseases. Helicobacter pylori is also associated with many skin disorders including, but not limited to, chronic urticaria, rosacea, lichen planus, atopic dermatitis, psoriasis, pemphigus vulgaris, vitiligo, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, primary cutaneous marginal zone B-cell lymphomas and cutaneous T-cell pseudolymphoma.

Inflammatory lobular hemangioma: A vascular proliferation with a prominent lymphoid component. Review of a series of 19 cases.

J Cutan Pathol 2021 Feb 30;48(2):229-236. Epub 2020 Sep 30.

Department of Pathology, University of Virginia, Charlottesville, Virginia, USA.

In the last 30 years, there has been a strong interest in vascular proliferations. Pyogenic granuloma was not only renamed lobular capillary hemangioma, but also the conceptual interpretation was also changed from an overgrowth of granulation tissue to a genuine hemangioma (or benign vascular neoplasm). We describe 19 cases of patients who presented clinically with a vascular lesion, characteristically a pyogenic granuloma or lobular hemangioma, where the histopathological findings led to the pathologic concern for a lymphoma of the skin.

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

Dermatol Ther 2020 05 30;33(3):e13410. Epub 2020 Apr 30.

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).

Ipilimumab/nivolumab-induced pseudolymphoma in a patient with malignant melanoma.

J Cutan Pathol 2020 Apr 13;47(4):390-393. Epub 2019 Nov 13.

Department of Dermatology and Cutaneous Surgery, University of South Florida, Tampa, Florida.

Combination therapy with ipilimumab and nivolumab is an adjuvant treatment approach for metastatic melanoma that boasts increased 3-year survival when compared with a single immunotherapy agent. Combination therapy, however, is associated with increased toxicities, especially cutaneous side-effects. Here we present a patient with metastatic melanoma and a sudden eruption of painful nodules on the face and arms 10 days after the administration of the fourth dose of combination ipilimumab/nivolumab.

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
