Multisystem Langerhans cell histiocytosis: Literature review and case report.

Radiol Case Rep 2022 May 2;17(5):1407-1412. Epub 2022 Mar 2.

Department of Radiology, Pham Ngoc Thach University of Medicine, Ho Chi Minh, Vietnam.

Langerhans cell histiocytosis (LCH) refers to a group of diseases of unknown etiology, typically discovered in childhood, characterized by the accumulation of Langerhans cells (white blood cells with large cell nuclei that may contain cytoplasmic histiocytosis X bodies) involving one or more organ systems, including bones, lungs, pituitary gland, skin, lymph nodes, and liver. This disease is also known as histiocytosis X or eosinophilic granuloma. Pulmonary LCH is common (identified in 40% of LCH patients) and may be isolated to the lung or involve other organs.

2022 American College of Rheumatology/European Alliance of Associations for Rheumatology Classification Criteria for Eosinophilic Granulomatosis with Polyangiitis.

Ann Rheum Dis 2022 03 2;81(3):309-314. Epub 2022 Feb 2.

University of Pennsylvania, Philadelphia, Pennsylvania, USA

Objective: To develop and validate revised classification criteria for eosinophilic granulomatosis with polyangiitis (EGPA).

Methods: Patients with vasculitis or comparator diseases were recruited into an international cohort. The study proceeded in five phases: (1) identification of candidate criteria items using consensus methodology, (2) prospective collection of candidate items present at the time of diagnosis, (3) data-driven reduction of the number of candidate items, (4) expert panel review of cases to define the reference diagnosis and (5) derivation of a points-based risk score for disease classification in a development set using least absolute shrinkage and selection operator logistic regression, with subsequent validation of performance characteristics in an independent set of cases and comparators.

Unique Recognizable Histopathologic Variant of Palisaded Neutrophilic and Granulomatous Dermatitis that Is Associated With SRSF2-Mutated Chronic Myelomonocytic Leukemia: Case Report and Review of the Literature.

Am J Dermatopathol 2022 Mar;44(3):e33-e36

Department of Dermatology, Henry Ford Health System, Detroit, MI; and.

Abstract: Palisaded neutrophilic and granulomatous dermatitis (PNGD) represents a cutaneous histopathologic reaction spectrum associated with several underlying disorders. Few cases of PNGD have been associated with chronic myelomonocytic leukemia (CMML), a malignant hematopoietic disorder with features in between those of a myeloproliferative neoplasm and myelodysplastic syndrome. We present a patient with a generalized papular skin reaction involving the neck, chest, and shoulders with histomorphological features on the spectrum of PNGD. Read More

J Int Med Res 2021 Jan;49(1):300060520982826

Department of Orthopaedic Surgery, National Taiwan University Hospital, Taipei, Taiwan.

The various presentations of osseous Langerhans cell histiocytosis (LCH) make it difficult to distinguish from other bone diseases. In addition, there is no universally accepted protocol for managing osseous LCH for single non-central nervous system-risk lesions. Here, the rare cases of two paediatric patients, aged 1 and 2 years, who presented with a solitary tibial lesion at time of LCH diagnosis, are reported. Read More

Nasal polyps in eosinophilic granulomatosis with polyangiitis: Structured histopathology and CD105 expression.

Am J Otolaryngol 2020 Nov - Dec;41(6):102661. Epub 2020 Aug 10.

Department of Neuroscience - DNS, Otolaryngology Section, Padova University, Via Giustiniani 2, 35128 Padova, Italy. Electronic address:

Purpose: Distinguishing the prodromal nasal polyposis of eosinophilic granulomatosis with polyangiitis (EGPA) from chronic rhinosinusitis with nasal polyps (CRSwNP) is a challenge for rhinologists and rheumatologists. It has recently been reported that angiogenesis and CD105 expressed on vascular endothelial cells could have a role in the pathogenesis and development of nasal polyps. This exploratory study examined the structured histopathology of nasal polyps in patients with EGPA and CRSwNP, comparing CD105 expression in their nasal tissue with that of a control group with no chronic sinonasal inflammation.

Vertebra Plana in Children May Result from Etiologies Other Than Eosinophilic Granuloma.

Clin Orthop Relat Res 2020 10;478(10):2367-2374

F. Baky, T. A. Milbrandt, C. Arndt, M. T. Houdek, A. N. Larson, Department of Orthopedic Surgery, Mayo Clinic, Rochester MN, USA.

Background: Vertebra plana in children is a diagnostic dilemma for orthopaedic surgeons. This radiographic finding sometimes has been said to be pathognomonic for eosinophilic granuloma (Langerhans cell histiocytosis); however, vertebra plana may also be caused by a range of other conditions. We sought to determine whether vertebra plana can be associated with malignancies other than eosinophilic granuloma. Read More
