    Background: The placement of a tattoo is a common event. Basal cell carcinoma arising from a tattoo is rare despite this neoplasm being the most common form of skin cancer. Objective: We describe a 41-year-old man who developed a basal cell carcinoma in his tattoo and review the literature of basal cell carcinomas originating in a tattoo. Methods: A literature search using PubMed was performed. The following terms were searched: “basal,” “carcinoma,” “cell,” and “tattoo.” The characteristics of individuals with a basal cell carcinoma originating in a tattoo were analyzed and summarized. Results: A total of 13 patients (6 women and 7 men) with a basal cell carcinoma arising in a tattoo have been reported. The majority of the tumors were located on the head (6 cases, 46.2%) followed by either an upper extremity (4 cases, 30.7%) or the trunk (3 cases, 23.1%). Most of the carcinomas were asymptomatic; however, 2 patients reported pruritus associated with their tumor. Nodular basal cell carcinoma was the most common subtype diagnosed (5 tumors), followed by superficial basal cell carcinoma (2 tumors). One patient had either a pagetoid or a mixed (nodular and sclerosing) histology. The pathological variant was not described for 4 patients. Conclusions: Basal cell carcinoma arising in a tattoo is a rare occurrence. Although this occurrence may be coincidental, emerging evidence of carcinogenesis associated with tattoo pigment may suggest a causal link. Elucidating this important relationship warrants further investigation

    Ultrasound-guided percutaneous periarterial thrombin injection for paracentesis-related hemoperitoneum

    Paracentesis is a common procedure used in the diagnostic evaluation of peritoneal fluid as well as the therapeutic removal of high-volume ascites. Although generally regarded as a safe procedure, complications may arise from arterial injury, including hematomas and pseudoaneurysms. Transcatheter embolization and surgery are first-line interventions for injuries refractory to conservative management. We present a case where a patient failed conventional therapies for hemoperitoneum following a paracentesis which resolved after thrombin injection into the subcutaneous tissues, a novel use for thrombin. Using a linear 12-3 MHz transducer, approximately 3000-3500 U of thrombin was injected through connecting tubing and a 25-gauge needle by the interventional radiologist into the subcutaneous tissues around the origin of the arterial hemorrhage. The bleeding ceased and the patient's hemoglobin and hemodynamics stabilized
