Panniculitides are a group of inflammatory disorders of the subcutaneous fat that have been reported as a rare complication of both a serine threonine kinase BRAF inhibitor monotherapy and BRAF inhibition in combination with a mitogen activated protein kinase (MEK) inhibitor combination therapy used to treat metastatic melanoma. The cutaneous manifestations of BRAF and BRAF/MEK therapies have been well documented, but neutrophilic panniculitis remains a less common complication with fewer case reports. Physician awareness of this complication when following patients on similar targeted therapies can decrease delays in appropriate management.

Bacterial infections commonly complicate cutaneous leishmaniasis (CL), worsening the disease and delaying healing. Despite this, there is a gap in research concerning the characteristics of pathogenic microorganisms associated in CL patients. This study aims to identify bacterial isolates and drug susceptibility patterns in CL patients.

Aberrant immune responses to viral pathogens contribute to pathogenesis, but our understanding of pathological immune responses caused by viruses within the human virome, especially at a population scale, remains limited. We analyzed whole-genome sequencing datasets of 6,321 Japanese individuals, including patients with autoimmune diseases (psoriasis vulgaris, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), pulmonary alveolar proteinosis (PAP) or multiple sclerosis) and coronavirus disease 2019 (COVID-19), or healthy controls. We systematically quantified two constituents of the blood DNA virome, endogenous HHV-6 (eHHV-6) and anellovirus.

Primary cutaneous amoebiasis is rare, and typically affects immunocompromised patients and presents with unique clinical and histopathologic changes. Untreated, the infection could progress to involve the central nervous system, which is almost universally fatal. We present a case of primary cutaneous acanthamoebiasis in a patient with chronic lymphocytic leukemia on acalabrutinib.

Primary effusion lymphoma (PEL) is a rare and aggressive B-cell lymphoma typically associated with human herpesvirus 8 (HHV-8) and Epstein-Barr virus infections. It classically presents as a malignant effusion in body cavities, but rarely presents with an extracavitary variant characterized by solid tumors in lymph nodes or extranodal sites such as the gastrointestinal tract, skin, lungs, and nervous system. This case report describes an unusual presentation of primary cutaneous extracavitary PEL in an HIV-positive patient that has only been reported in 8 cases previously.
