Viral Hepatitis Among African Immigrants with Hepatocellular Carcinoma in Minnesota: High Prevalence Yet Low Awareness.

We aimed to study the virologic profile of immigrants from Africa with viral hepatitis-related hepatocellular carcinoma (HCC) who received care at our institution. We conducted a descriptive study among African-born patients with HCC who received care at University of Minnesota Medical Center from 2011 to 2018. We analyzed the prevalence, virologic profiles and treatment of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections prior to HCC diagnosis. 74 African-born patients with HCC were eligible for analysis. 54 had HCV and 20 had HBV infection. 80% of HBV patients were treated but remained with inadequate viral suppression at the time of HCC diagnosis while only 39% of HCV patients were treated prior to HCC diagnosis. Lost to follow up was common in both groups. Our findings suggest that there is a significant gap in appropriate viral hepatitis care in an African immigrant population in Minnesota. Culturally-appropriate strategies are needed to bridge this gap.

Pulmonary Mycobacterium Spindle Cell Pseudotumor in Patient With Liver Transplant.

We report a case of liver transplant patient who presented with lung masses, found to be Mycobacterium spindle cell pseudotumors. The masses demonstrated hypermetabolic activities on positron emission tomography. Core biopsy revealed sheets of spindle histiocytic cells with abundant acid-fast bacilli identified as Mycobacterium avium-intracellulare complex. This finding is a rare presentation of Mycobacterium infection, mainly nontuberculous Mycobaterium. It is characterized by a benign, spindle cell mass-forming reaction. Most of the reported cases had acquired immune deficiency syndrome or organ transplant. Histopathology illustrating the proliferation of spindle cell shaped histiocytes containing numerous acid-fast bacilli is the gold standard for diagnosis. The standard treatment has not been well established; previously reported cases followed the standard treatment for Mycobacterium based on organ involvement. Our case is the first case to our knowledge that reports pulmonary Mycobacterium spindle cell pseudotumors in a liver transplant recipient.
