Agenesis of the left hepatic lobe is a rare anomaly described as the absence of liver tissue on the left side of the gallbladder fossa or falciform ligament. Here we report a case of agenesis of the left hepatic lobe identified during educational dissection of an 84-year-old male formalin-fixed cadaver. The gross anatomical characteristics, embryological origin, and clinical relevance of this rare variation are described in this report.

A very rare anatomical variation of external jugular vein\'s penetration by the transverse cutaneous nerve of the neck is displayed in the current study. The phenomenon of veins\' fenestration or penetration by other structures, such as nerves along with its likely embryologic development are discussed. Moreover, the potential clinical significance of that variation\'s awareness on behalf the physician is discussed in detail.

Choriocarcinoma is a rare kind of cancer, which may be either gestational or non-gestational. Choriocarcinoma is responsible for about a quarter of all documented neoplastic aneurysms. It is a descriptive case report of choriocarcinoma transmission from a donor, following kidney donation. A 45-year-old woman got a kidney from a 25-year-old woman who was taken to the hospital due to a non-traumatic cerebral hemorrhage. She delivered a healthy baby 48 days before her brain death. The transplant was successfully done. Five weeks\' post-transplantation, the recipient had pain and erythema in the surgical area. Regarding the high level of beta-human chorionic gonadotropin in her blood, diagnostic tests were performed. Following the confirmation of the cancer, a five-phase chemotherapy plan with various pharmaceutical regimens was initiated. Liver function test values rose after the final round of chemotherapy, and the patient developed hepatic encephalopathy. Considering the thrombocytopenia, dialysis, or hemoperfusion, which are normally performed to reduce liver enzymes, were not initiated. Finally, she died due to the hepatic failure and disseminated intravascular coagulation. Although the nephrologists disagree on the optimal course of treatment, it seems that nephrectomy would be helpful in such instances. Physicians should be aware of the possibility of transplant-related choriocarcinoma in female donors of reproductive age who die because of intracerebral brain hemorrhage for unclear reasons. Every donor must undergo a thorough examination. It is critical to get documents, clarify history, and interview relatives.

Arterial tortuosity describes variation via bending of the arterial wall and has been noted in several arteries throughout the body. Tortuous blood vessels can cause nerve compression, as well as present difficulties to surgeons and radiologists. Here we present an unusual case of multi-vessel arterial tortuosity discovered in 78-year-old Hispanic male cadaver, independent of systemic pathology. The left ulnar and right tibial arteries were dissected, and using calibrated digital calipers, their external and internal diameters were measured both at the origin site and at the site of greatest dilation. Both wall thickness and the number of inflection points were also measured. Six bends were noticed in the ulnar artery and its diameter measured 8.11 mm at its widest, with a wall thickness of 0.88mm. On the lower extremity, the right tibial artery had three bends and its diameter measured 4.86 mm at its widest, with a wall thickness of 1.32 mm. This uncommon tortuosity is not only more prone to laceration during surgery, but the bending and thickening can be mistaken for tumors. Finally, fluid dynamics can be altered, resulting in an impact on blood pressure in the extremities. Thus, raising awareness is crucial to prevent both symptoms and iatrogenic complications.
