Uncommon Presentation of a Giant Cell Tumor of the Tendon Sheath of the Hand: A Case Report

A giant cell tumor of the tendon sheath (GCTTS) presents as a rare neoplasm demanding a heightened index of suspicion for precise diagnostic evaluation, especially when manifesting in the digital phalanges, as it is part of a group of neoplasms known as tenosynovial giant cell tumors (TCGTs). An accurate and timely diagnosis is crucial, as it significantly enhances treatment outcomes for this heterogeneous group of lesions. We describe the case of a male patient who presented with multiple nodules in the fourth finger of his left hand and was ultimately diagnosed with a localized form of a GCTTS, an unusual presentation for localized forms of this entity. Our objective is to outline the diagnostic and therapeutic approach, discussing options for differential diagnosis and treatment modalities. To achieve this, we conducted a literature review and compared our findings and the observed evolution in our patient. Early recognition of hand tumors allows for timely diagnosis, facilitating optimal resections during surgical procedures. This, in turn, reduces morbidity and enhances the functionality of the affected extremity, as detailed in the current case.

Overcoming Anatomical Challenges: Laparoscopic Cholecystectomy in Situs Inversus Totalis

Situs inversus totalis (SIT) is a rare genetic condition characterized by the sagittal inversion of thoracoabdominal organs. Surgeons may face substantial challenges when dealing with surgical pathologies in SIT patients, particularly those involving the gallbladder and bile ducts, such as cholelithiasis and acute cholecystitis. In this report, we present the case of a 46-year-old male with a previously known diagnosis of SIT, who presented with recurrent episodes of atypical abdominal pain. Cholelithiasis was diagnosed through ultrasound and as a result, elective surgery was scheduled. In addition, we detail the adjustments implemented by our surgical team in the laparoscopic cholecystectomy procedure, which contributed to a successful surgical outcome. Nevertheless, like any patient, those with SIT are not exempt from postoperative complications, as detailed in this case. Hence, we emphasize the importance of comprehensive preoperative diagnostics to reduce the risk of perioperative complications in this group of patients.
