The human vascular system exhibits a remarkable degree of anatomical variability, with deviations from conventional arterial branching patterns occasionally encountered. Among these variations, the atypical bifurcation has drawn attention for its infrequent occurrence and potential clinical implications. This study investigates the rare anatomical variation of high bifurcation seen during cadaver dissection in the brachial artery. It emphasizes the relevance of understanding such variations in established vascular anatomy and their clinical implications. Detailed findings from the dissection of the upper limbs, which reveal a high bifurcation in a 40-year-old male cadaver, are presented. The report highlights unique anatomical variations, including a superficial path. The conclusion underscores the rarity of this high bifurcation and its potential impact on medical procedures. It stresses the importance of healthcare professionals being aware of and prepared for such anatomical variations for optimal patient care. In order to manage potential difficulties during medical operations affecting the circulatory system and eventually enhance patient outcomes, it is necessary to understand these deviations.

UNASSIGNED: Primary and metastatic carcinoma of the small intestine are rare. While most of these malignancies are adenocarcinomas, squamous cell carcinoma (SCC) of the gastrointestinal tract is uncommon. We present a case report of a rare occurrence of skin SCC metastasizing to the ileum, highlighting diagnostic challenges and clinical implications.
METHODS: An 83-year-old female had a history of cutaneous SCC excision in the right temporal region two years prior to the current emergency department visit, followed by metastatic recurrence in a right intra-parotid lymph node treated with radiotherapy. The patient exhibited septic shock and an acute abdomen, and an abdominal computed tomography scan revealed signs of intestinal perforation. Emergency exploratory laparotomy confirmed purulent peritonitis and perforation of the terminal ileum. Subsequently, a 20 cm intestinal resection was performed. Histopathological examination of the resected specimen revealed a 4 cm perforated SCC of the small intestine (pT4 pN0 L0 V1 Pn0 R0).
UNASSIGNED: Metastases of the small intestine are rare. The primary sites for these metastases are typically the uterus, cervix, colon, lung, breast, or melanoma. SCC of the small intestine is particularly rare and poses challenges in diagnosis owing to non-specific symptoms. The prognosis for SCC of the small intestine is generally poor, and the potentially aggressive behavior of some skin SCC emphasizes the need for increased awareness and vigilance in managing such cases.
CONCLUSIONS: This case report underscores the importance of considering metastatic disease in the small bowel of patients with a history of skin SCC who present with new-onset abdominal symptoms.
