Recurrent eosinophilic granuloma involving maxilla and mandible in an adult male: An unusual case report.

Aust Dent J 2021 May 27. Epub 2021 May 27.

State Key Laboratory of Oral Diseases, West China Hospital of Stomatology, Sichuan University, China.

Langerhans cell histiocytosis (LCH) is a disease spectrum characterized by the intense infiltration/accumulation of Langerhans' cells in the affected tissues. Eosinophilic granuloma is the mildest form of LCH which mainly affects the skull, mandible, ribs and femur in children and young adults but rarely occurs in the maxilla. Here, we describe an unusual case of Eosinophilic granuloma affecting the tissues adjacent to tooth #25 and tooth #46 (FDI numbering system) in a 35-year-old male. Read More

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 Oct;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

Canine eosinophilic pulmonary granulomatosis: case report and literature review.

J Vet Diagn Invest 2020 Mar;32(2):329-335

Department of Veterinary Pathology, Western College of Veterinary Medicine, University of Saskatchewan, Saskatoon, Saskatchewan, Canada. Current address: Tudor Glen Veterinary Hospital, St. Albert, Alberta, Canada (Abbott).

We describe and illustrate herein a case of eosinophilic pulmonary granulomatosis (EPG) in a 16-mo-old, castrated male, Great Pyrenees crossbred dog. EPG appears to differ from eosinophilic pneumonias and eosinophilic bronchopneumopathy in dogs by the presence of nodules and masses in the lungs composed of eosinophils, macrophages, and various combinations of lymphocytes, plasma cells, neutrophils, and mast cells within fibrous tissue. Specific information from this dog was added to the information from the limited number of other dogs diagnosed with EPG reported in the veterinary literature, and the information analyzed.
