A case of granular cell tumor of the trachea

Case report: Bronchoscopic intervention for rare benign airway tumors: a report of 4 cases and literature review

Due to their unique location, airway tumors have a significant impact on patient quality of life and survival. Current research has focused extensively on malignant airway tumors; however, benign airway tumors, especially rare ones, are less understood due to their low incidence. These tumors are often misdiagnosed and mistreated due to diagnostic challenges. Therefore, there is still a lack of consensus on the treatment of some rare benign airway tumors. Our center summarizes the diagnosis and treatment of four rare cases of benign airway stenosis in recent years, highlighting the bronchoscopic manifestations and therapeutic approaches to improve the understanding of these diseases.

Case Report: Defect repair post-resection of cervical tracheal granular cell tumor by cervical anterior banded myofascial flap: A case study and literature review

Objective

A case of cervical tracheal granular cell tumor (CTGCT) is reported together with a discussion on the clinical manifestation, diagnosis, and treatment of CTGCT. Additional cases of tumors in the tracheal membrane are also discussed. A simple and viable tracheal reconstruction method was proposed. The research design involves a case report and literature review.

Methods

Twenty-four case reports on cervical GCT with complete clinical data were identified, with a specific focus on cases involving surgical treatment of tumors in the cervical tracheal membrane.

Results

Twenty-eight reports of GCT in the cervical trachea and six reports on cervical tracheal membrane tumors were identified. The clinical data of a middle-aged Asian woman with a cervical GCT was also discussed.

Conclusion

Cervical GCT is a rare disease, and tracheal resection is a reasonable treatment for cervical tracheal GCT. The proposed procedure is a simple and feasible method for reconstruction of the cervical tracheal membrane defect using a double-pedicled banded myofascial flap.

Large tracheoesophageal granular cell tumor: An atypical case presentation, location, and management

Introduction

Presentation of case

Conclusion

•

Granular cell tumors (GCT) are rare tumors of the head and neck.

•

A 42-year-old man presented to the Emergency Department after a motor vehicle accident with a 3.2 × 5.5 cm mass anterior to the esophagus and posterior to the tachea.

•

The patient underwent a transcervical excision of the retrotracheal tumor, which was positive for CD68, CD163, S100, and SOX10, confirming a GCT.

•

This is a distinctive presentation of a large (5.5cm) GCT in the plane between the trachea and esophagus that hasn't been shown in the literature

Rare case of granular cell tumor of perianal region: a case report and literature review

Granular cell tumors (GCTs) are rare submucosal neoplasms, with tumors in the oral mucosa accounting for about a third of all cases. In contrast, GCT is a rare anal neoplasm, with fewer than 30 cases of perianal GCT reported in the literature. We report the case of a 36-year-old woman with a perianal lump with no obvious local lesion as the main clinical complaint. The tumor was completely resected and histologically confirmed as a GCT. The patient remained under continuous follow-up. GCT is difficult for surgeons and pathologists to diagnose, and biopsy and immunohistochemical analysis are prerequisites for an accurate diagnosis. An integrated understanding of GCT in terms of its differential diagnosis will contribute to better identification and more appropriate treatment of this disease.

Granular cell tumor of the trachea as a rare cause of dyspnea in a young woman

Tracheal granular cell tumors are rare neurogenic neoplasms characterized by an indolent behavior. We report the case of a young woman affected by this tumor with non-specific clinical presentation. We performed a literature search in order to identify all the cases of tracheal granular cell tumor and to summarize the current state of knowledge about this rare disease.

Adjuvant radiation therapy for malignant Abrikossoff's tumor: a case report about a femoral triangle localisation

Background

Granular cell or Abrikossoff’s tumors are usually benign however rare malignant forms concern 1 to 3% of cases reported. Pelvic locations are exceptional.

Case presentation

We report a case of a 43-years-old patient who had a benign Abrikossoff’s tumor localized in the right femoral triangle diagnosed at the biopsy. The patient underwent a surgical tumorectomy and inguinal lymph nodes resection. Histologically, the tumor showed enough criteria to give diagnosis of malignancy: nuclear pleomorphism, tumor cell spindling, vesicular nuclei with large nucleoli. Moreover, five lymph nodes were metastatic. Immunohistochemistry findings confirmed the diagnosis of granular cell tumor which is positive for S100 protein and CD68 antibodies. The mitotic index was nevertheless low with a Ki67 labeling index of 1–2%. A large surgical revision with an inguinal curage following radiotherapy were decided on oncology committee. Adjuvant radiotherapy on the tumor bed and right inguinal area of ​​50 Gy in conventional fractionation was delivered with the aim of reducing local recurrence risk. There was no recurrence on longer follow-up (10 months post radiotherapy).

Conclusions

Adjuvant radiotherapy seems an appropriate therapeutic approach, even if controversial, given that some authors report effectiveness on local disease progression.

Unusual Granular Cell Tumor of the Trachea Coexisting With Papillary Thyroid Carcinoma and Masquerading as Tracheal Invasion of Recurred Thyroid Carcinoma: A Case Report

This was an extremely rare case of unusual granular cell tumor of the trachea coexisting with recurrent papillary thyroid carcinoma. We initially misdiagnosed this patient as having tracheal invasion from recurrent thyroid carcinoma even after a computed tomography scan and fine-needle aspiration cytology.Clinicians should be aware of the possibility of granular cell tumor of the trachea occurring simultaneously with papillary thyroid carcinoma.

Multiphasic multidetector computed tomography study of a rare tracheal tumor: granular cell tumor

Our aim is to present the case report of a woman affected by tracheal granular cell tumor analysed by multiphasic contrast-enhanced multidetector CT. The tumor presents as polypoid lesion (diameter 13 mm), with smooth and well-defined margins, elevated contrast enhancement in arterial phase, and a modest release of contrast in venous phase. This pattern is quite different from the other tracheal tumours. We have performed a comprehensive review of literature to assess all cases of granular cell tumors of the trachea; only 40 cases are reported. Of these, no one focused on the contrast enhancement aspect, so our work is the first showing a specific pattern in multidetector computed tomography (MDCT) of the tracheal granular cell tumour and may help in differential diagnosis.
