Abstract
A woman in her 50s presented with a rounded and hypervascular lesion in the right internal iliac lymph node chain, contacting with small branches of the anterior division of the internal iliac artery. Since the lesion matched the blood arterial pool in CT and the patient exhibited multiple vascular abnormalities that suggested segmental arterial mediolysis, a pseudoaneurysm hypothesis was initially made. Arteriography was realised due to the intention for embolisation of the pseudoaneurysm, but the dynamic behaviour during the exam suggested a hypervascular tumour more. An MRI was conducted, bringing new evidence, favouring the possibility of a neoplasm. The lesion excision was performed and sent to pathology. Morphological and immunohistochemical findings suggested a rare case of a fibroblastic reticular cell tumour of the internal iliac lymph node.

A Fibroblastic Reticular Cell Tumour Arising in the Oral Cavity: A Case Report and Review of the Literature. Head Neck Pathol 2022:10.1007/s12105-022-01496-9. [PMID: 36344905 DOI: 10.1007/s12105-022-01496-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Revised: 09/15/2022] [Accepted: 09/16/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Tumours of dendritic or histiocytic lineage are amongst the rarest tumours and probably account for < 1% of tumours affecting the lymph nodes or soft tissue. Because several of these entities were poorly recognised until recently, the true incidence is not determined. METHODS We present what we believe is the first reported case report of a fibroblastic reticular cell tumour arising in the oral cavity as well as reviewing the current literature regarding this rare subset of tumours. RESULTS We discuss the clinical and histopathological findings of our reported case and examine the literature regarding this entity. We discuss the key differential diagnoses to consider when making this diagnosis. CONCLUSION Histiocytic and dendritic cell derived tumours are exceptionally rare within the head and neck region although a number of these tumours have been reported within the oral cavity. We present what we believe is the first reported case of a fibroblastic reticular cell tumour arising within the oral cavity.

Abstract
Context.—
Although rare in everyday practice, the initial presentation of hematopoietic neoplasms other than lymphoma in the musculoskeletal system and other extranodal sites can generate challenging diagnostic problems for surgical pathologists.
Objective.—
To review the morphologic and immunophenotypic features of various nonlymphoid hematopoietic diseases presenting at extranodal sites, with emphasis on the inherent diagnostic pitfalls and differential diagnoses of these entities to aid surgical pathologists in their accurate recognition.
Data Sources.—
Cases reviewed herein represent both in-house and consult cases seen at our institution between 2010 and 2021.
Conclusions.—
Entities that present in this way include myeloid neoplasms and histiocytic/dendritic cell neoplasms. These tumors commonly cause nonspecific symptoms, and their histologic appearance can overlap with a variety of benign neoplasms and reactive processes. This can lead to delay in diagnosis and intervention with potentially lifesaving therapy; thus, accurate and expedient recognition is of paramount importance.

World Neurosurg 2020; 141:20-24. [PMID: 32497850 DOI: 10.1016/j.wneu.2020.05.190] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 05/19/2020] [Accepted: 05/20/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND The authors present the first reported case of a fibroblastic reticular cell tumor (FRCT) presenting with spinal cord compression. FRCTs are the rarest subset of dendritic cell tumors, a specific group of hematologic malignancies. FRCTs reportedly behave similar to low-grade sarcomas as opposed to malignant tumors. CASE DESCRIPTION A 45-year-old female patient presented with a 2-and-a-half week history of a flu-like illness and 1 week history of lower limb imbalance. Magnetic resonance imaging revealed an extradural lesion at T3/4 compressing the spinal cord. Initially, the patient was presumed to have metastatic spinal cord compression, and she underwent a decompressive thoracic laminectomy with debulking of the lesion with follow-up adjuvant radiotherapy. However, histology identified a unique primary FRCT originating from spine, not secondary metastatic spinal cord compression. There were no histologically aggressive features likely contributing to the favorable outcome following surgery and adjuvant radiotherapy. Her postoperative recovery was unremarkable, and she recovered fully. CONCLUSIONS Although rare, we report the first case of FRCT originating in the spine causing spinal cord compression. The clinical presentation of the case, histologic features of FRCT, and the treatment options are reviewed.

Abstract
Histiocytic and dendritic cell neoplasms (HDN) are rare and their biology, prognosis, treatment and terminology are still under discussion. They are composed of macrophage and dendritic-derived cells and show a wide range of clinical, morphological and prognostic features. Clinicopathological correlation and a broad immunohistochemical panel are required to establish a correct diagnosis. After the detection of BRAF mutations in Langerhans cell histiocytosis, the potential role of other molecular alterations is being studied. We have reviewed the literature published in the last 10 years to provide an overview of NHD, with particular emphasis their molecular features.

An Overt, Obscure Gastrointestinal Bleed Caused by a Primary Small Bowel Fibroblastic Reticular Cell Sarcoma. ACG Case Rep J 2018; 5:e22. [PMID: 29577056 PMCID: PMC5852304 DOI: 10.14309/crj.2018.22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2017] [Accepted: 01/25/2018] [Indexed: 11/17/2022] Open
Abstract
Small bowel bleeding should be considered in patients who continue to bleed despite a negative upper endoscopy and colonoscopy. The differential diagnosis of small bowel bleeding can include infection, inflammatory conditions, vascular malformations, and, rarely, malignancy. This report demonstrates a rare, primary, small bowel, reticular cell sarcoma presenting as an overt gastrointestinal bleed. These tumors are difficult to diagnose because they are rarely seen on traditional cross-sectional imaging and can present with multiple synchronous lesions throughout the intestinal tract.
