Unique Case of Rare Non-Neural Granular Cell Tumor of the Rectus Abdominis Muscle

Background and Objectives: Our report contributes a unique case of a non-neural GCT occurring in an unusual location, with its development during pregnancy adding to its rarity. Materials and Methods: Granular cell tumors (GCTs), also known as Abrikossoff's tumors, are rare neoplasms of Schwann cell origin with predominantly benign behavior. We present a case of a 29-year-old female with a non-neural variant of a GCT discovered incidentally during a cesarean section, situated on the posterior surface of the rectus abdominis muscle. Results: Histologically, the tumor exhibited features consistent with a benign non-neural GCT, confirmed through an immunohistochemical analysis. Despite the atypical presentation and challenging surgical removal due to prior scarring, the patient experienced no postoperative complications and showed no signs of recurrence during follow-up. Conclusions: This case highlights the importance of considering GCTs in differential diagnoses, particularly in unusual anatomical locations, and underscores the favorable prognosis associated with timely surgical intervention.

Association of and polymorphisms with sarcoidosis in a Greek patient cohort

INTRODUCTION

Sarcoidosis is a disease that results from a combination of environmental and genetic factors. Its genetic basis however, is yet to be clarified. The purpose of this study is to determine whether single nucleotide polymorphisms (SNPs) of the B-cell activating factor (BAFF) and its receptor (BAFF-R) are associated with sarcoidosis.

MATERIAL AND METHODS

Blood samples from one hundred and seventy-three sarcoidosis patients and one hundred and sixty-four controls were collected. All samples were genotyped for BAFF rs2893321, rs1041569 and rs9514828, and for BAFF-R rs61756766.

RESULTS

Out of the three BAFF polymorphisms, none genotype had any significant association with sarcoidosis, although the T allele in rs1041569 and rs9514828 was overrepresented in sarcoidosis patients. A marginally significant association with sarcoidosis was found in the case of the CT genotype and T allele of BAFF-R rs61756766. Haplotype analysis of the BAFF polymorphisms was also performed, revealing an overrepresentation of the ATT, GTA and GTT haplotypes in the group of patients with cardiac involvement.

CONCLUSIONS

Taken together, the results of this study suggest a possible relationship between BAFF SNPs, rs1041569 and rs9514828, and BAFF-R SNP rs61756766 with sarcoidosis susceptibility and their potential as biomarkers for the disease.
