Colonic lipomas are rare benign tumours, usually without any symptoms, and most occur in the caecum and ascending colon. We describe a patient with upper rectal intussusception caused by a giant rectal lipoma; no similar report of this type of case has been published. ⋯ Laparoscopic segmental resection of the rectum with LCA preservation is safe and feasible for the treatment of upper rectal intussusception caused by a giant rectal lipoma.

The outcomes following anterior approach (AA) hepatectomy in huge hepatocellular carcinoma (HCC) patients with diaphragmatic invasion (DI) remain unclear. This study compared the outcomes of single huge right HCC patients with and without DI after AA hepatectomy. A total of 203 consecutive patients with single huge right lobe HCC who underwent AA major hepatectomy were included. ⋯ The subgroup analysis also showed that patients with tumor resection en bloc with part of the diaphragm had similar OS and RFS rates as those who underwent diaphragmatic resection after hepatectomy. Tumor diameter ≥ 15 cm, serum AFP level ≥ 400 ng/mL, and tumor grade of G4 and microvascular invasion are independent predictors of poor prognosis. For the single huge right lobe HCC patients with DI, AA major hepatectomy combined with diaphragmatic resection could offer similar OS and RFS as those without diaphragmatic invasion.

Familial hydatidiform mole is extremely rare while familial gestational trophoblastic neoplasia (GTN) has never been reported. Inspired by 2 biological sisters with postmolar GTN and liver toxicity, we reviewed susceptible maternal-effect genes and explored the role of possible drug transporter genes in the development of GTN. ⋯ We speculated that the known or unknown NLRP7 and KHDC3L mutations might be correlated with drug disposition in liver while liver drug transporters such as P-glycoprotein family that are also expressed in trophoblasts might be correlated to GTN susceptibility. Future genomic profiles of large samples alike using next generation sequencing are needed to confirm our hypothesis and discover yet unknown genes.

T-cell prolymphocytic leukaemia (T-PLL) is a rare aggressive lymphoid disease featured by a significant increased lymphocyte count and obvious hepatosplenomegaly with poor prognosis. The concomitant presentation of T-PLL and visceral leishmaniasis (VL) has not previously been reported. ⋯ Due to the rarity of the disease combination, the pathogenesis association of T-PLL and VL is unclear. However, a duly diagnosis is crucial for treatment. In immunosuppressed patients due to malignancies and treatment, VL should be considered as an opportunistic infection. In VL infections, the clinical manifestations mimicking hematological malignancies may cover up the underlying disease. Under such conditions, a complete work-up based on laboratory test is necessary to achieve a correct diagnosis.

Cerebral microbleeds are lesions that appear as round low signal intensity areas with a diameter of 2-5 mm on gradient echo T2-weighted sequence magnetic resonance imaging. Cerebral microblees are hemorrhages found in the brain parenchyma and they are caused by the extravasation of the blood. Although more patients with ischemic stroke are found to have cerebral microbleeds, only a few studies have evaluated other neurologic abnormalities outside of cognitive dysfunction due to cerebral microbleeds. ⋯ Cerebral microbleeds have been considered to be asymptomatic lesions thus far. However, recent studies have reported the association of cerebral microbleeds with neurological symptoms including cognitive dysfunction. This study confirmed the presence of newly formed cerebral microbleeds through imaging follow-ups whenever a symptom occurred.
