Hodgkin's lymphoma in a patient on adalimumab treatment for psoriasis

Current Medical and Surgical Treatment of Hidradenitis Suppurativa-A Comprehensive Review

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease presenting with recurrent inflammatory lesions in intertriginous body regions. HS has a pronounced impact on patients' quality of life and is associated with a variety of comorbidities. Treatment of HS is often complex, requiring an individual approach with medical and surgical treatments available. However, especially in moderate-to-severe HS, there is an urgent need for new treatment approaches. In recent years, increased research has led to the identification of new potential therapeutic targets. This review aims to give a comprehensive and practical overview of current treatment options for HS. Furthermore, the clinically most advanced novel treatment approaches will be discussed.

A Rare Case of Epstein-Barr Virus-Positive T-Cell Lymphoma in the Skin of an Immunocompromised Patient

ABSTRACT

Immunodeficiency-associated lymphoproliferative disorders are associated with latent infection by Epstein-Barr virus (EBV). Most cases of EBV-positive immunodeficiency-associated lymphoproliferative disorders arise from B cells, although some are of T-cell or natural killer origin. Cutaneous involvement is unusual and sporadically reported in the literature. We describe a rare case of an EBV-positive T-cell lymphoma presenting in the skin of a 32-year-old woman using adalimumab for neurosarcoidosis.

Primary Central Nervous System Lymphoma in a Patient on Adalimumab Therapy for Chronic Plaque Psoriasis

BACKGROUND

Adalimumab (Humira) is a recombinant human monoclonal antibody against tumor necrosis factor alpha, which works by blocking the interaction of tumor necrosis factor alpha with its cell-surface receptors, thereby limiting the progression of inflammatory pathways. Its use is approved for several autoimmune conditions, including chronic plaque psoriasis, for which it has been prescribed as a first-line biologic treatment. Increased risks of malignancy, particularly nonmelanoma skin cancer and non-central nervous system lymphomas, have been reported with use of this drug; however, there have been no reports of central nervous system lymphomas.

CASE DESCRIPTION

A 43-year-old man presented for evaluation following recent speech difficulty and a generalized tonic-clonic seizure. His medical history was significant for plaque psoriasis, for which he had been receiving treatment with adalimumab for 4 months. Magnetic resonance imaging scan of the brain with contrast agent showed a well-defined rounded enhancing lesion in the left temporal lobe with circumferential vasogenic edema. Mass effect was noted. Computed tomography scan of the chest, abdomen, and pelvis was unremarkable. He underwent excisional biopsy, and the preliminary intraoperative pathology report revealed a diagnosis of high-grade lymphoma. Subsequent analysis of morphology and immunophenotyping was consistent with primary diffuse large B-cell lymphoma of the central nervous system. Use of adalimumab was discontinued. Following combination therapy with high-dose methotrexate and rituximab along with 20 sessions of cranial radiation therapy, the patient was disease-free at 14-month follow-up.

CONCLUSIONS

We report the first case to our knowledge showing a possible association of central nervous lymphoma and adalimumab.
