ABSTRACT
BACKGROUND AND AIMS: Alcohol relapse after surviving an episode of alcohol-associated hepatitis (AH) is common. However, the clinical features, risk factors, and prognostic implications of recurrent alcohol-associated hepatitis (RAH) are not well described. APPROACH AND RESULTS: A registry-based study was done of patients admitted to 28 Spanish hospitals for an episode of AH between 2014 and 2021. Baseline demographics and laboratory variables were collected. Risk factors for RAH were investigated using Cox regression analysis. We analyzed the severity of the index episodes of AH and compared it to that of RAH. Long-term survival was assessed by Kaplan-Meier curves and log-rank tests. A total of 1118 patients were included in the analysis, 125 (11%) of whom developed RAH during follow-up (median: 17 [7-36] months). The incidence of RAH in patients resuming alcohol use was 22%. The median time to recurrence was 14 (8-29) months. Patients with RAH had more psychiatric comorbidities. Risk factors for developing RAH included age <50 years, alcohol use >10 U/d, and history of liver decompensation. RAH was clinically more severe compared to the first AH (higher MELD, more frequent ACLF, and HE). Moreover, alcohol abstinence during follow-up was less common after RAH (18% vs. 45%, p <0.001). Most importantly, long-term mortality was higher in patients who developed RAH (39% vs. 21%, p = 0.026), and presenting with RAH independently predicted high mortality (HR: 1.55 [1.11-2.18]). CONCLUSIONS: RAH is common and has a more aggressive clinical course, including increased mortality. Patients surviving an episode of AH should undergo intense alcohol use disorder therapy to prevent RAH.
ABSTRACT
Red dot basal cell carcinoma is a distinctive clinical subtype of basal cell carcinoma. It has been reported in eight individuals with a male to female ratio of 1:1; and the patients' ages ranged from 50 to 74 years. All patients had prior history of actinic keratoses and basal cell carcinoma. In addition, some patients also had prior squamous cell carcinoma, malignant melanoma, and/or dysplastic nevus. The tumor was usually of recent onset, asymptomatic, and on sun-exposed skin. It was most commonly located on the nose (five patients); other sites were the upper lip, the mid back, or thigh-each in one patient. The red dot basal cell carcinoma was solitary and small-usually 4 mm or less in diameter. It typically presented as a red macule or papule; however, it sometimes appeared as a flesh-colored or pink to light-red papule with a bright-red central area. Microscopic features showed basaloid tumor cells (arranged as either nodular aggregates or superficial buds or both). In the central portion of the lesion, there was a proliferation of erythrocyte-containing vascular spaces between the epidermis and the neoplasm. The basal cell carcinoma pathology subtype was either nodular and superficial (three patients), nodular (two patients), or superficial (one patient). The clinical differential diagnosis of red dot basal cell carcinoma included not only benign vascular lesions (such as hemangioma and telangiectasia) but also inflammatory conditions and adnexal tumors. Other basaloid cell neoplasms were in the pathologic differential diagnosis. The pathogenesis of red dot basal cell carcinoma is similar to that of other basal cell carcinoma clinical subtypes. Mohs surgery is the treatment of choice for red dot basal cell carcinomas. Red dot basal cell carcinoma has two categories of biologic behavior based on the ratio of the postoperative wound size as compared with the size of the preoperative tumor: nonaggressive (for which the ratio was 5:1 or less for three patients) and aggressive (for which the ratio was greater than 12:1 for three patients). There was no recurrence of the red dot basal cell carcinoma after treatment. In conclusion, the incidence of red dot basal cell carcinoma-a unique morphologic variant of basal cell carcinoma-may be higher than suggested by the number of reported patients with this basal cell carcinoma subtype.
ABSTRACT
BACKGROUND: Liver transplant recipients have an increased incidence of malignancies, but it is unclear whether they have a higher risk of colorectal cancer. AIM: To investigate whether liver transplant recipients have an increased risk of developing colorectal adenomas (a surrogate marker of colorectal cancer risk). PATIENTS AND METHODS: One hundred thirty-nine liver transplant recipients (excluding primary sclerosing cholangitis) who underwent a colonoscopy and polypectomy before and after transplantation, and 367 nontransplanted patients who underwent a colonoscopy for colorectal cancer screening and a second colonoscopy later were retrospectively studied. The risks of incident colorectal adenomas and high-risk adenomas (advanced or multiple adenomas or carcinomas) were compared between both cohorts. RESULTS: Incident colorectal adenomas were found in 40.3% of the transplanted patients and 30.0% of the nontransplanted patients (15.1% and 5.5%, respectively, had high-risk adenomas). After adjusting for age, sex, presence of adenomas in the baseline endoscopy, and interval between colonoscopies, transplant recipients showed a higher risk of developing colorectal adenomas (OR: 1.61; 95% CI: 1.05-2.47; p = .03) and high-risk adenomas (OR: 2.87; 95% CI: 1.46-5.65; p = .002). CONCLUSIONS: Our results suggest that liver transplant recipients have an increased risk of developing colorectal adenomas and lesions with high risk of colorectal cancer.

Posttransplant lymphoproliferative disorders define an important form of lymphoproliferative disease causally linked with a state of iatrogenic immune dysregulation inherent to the posttransplant setting. Most posttransplant lymphoproliferative disorders are in the context of Epstein-Barr virus-associated B-cell lymphoproliferative disease, most notably diffuse large-cell B-cell lymphoma. A less common variant falls under the rubric of posttransplant T-cell lymphoproliferative disease, which is largely unrelated to Epstein-Barr virus infection. Anaplastic large-cell lymphoma (ALCL) is the most recognized form of posttransplant T-cell lymphoproliferative disease. Although the 6p25.3 translocation is seen in a variety of B-cell lymphoproliferative disorders, this particular translocation in the spectrum of T-cell lymphoproliferative disease is a fairly specific finding pointing toward a diagnosis of primary cutaneous ALCL and a rare subset of lymphomatoid papulosis. This translocation in the peripheral T-cell lymphoma setting serves as a favorable prognostic predictor. We report a case of an 81-year-old heart transplant recipient who developed an expansile neck mass 17 years after his heart transplant. A diagnosis of cutaneous ALCL was subsequently made with cytogenetic analysis yielding the 6p25.3 translocation. The characteristic biphasic morphology of a small-cell epidermotropic neoplastic cell populace in concert with a dermal based large-cell infiltrate characteristic for those cases of ALCL harboring this translocation was seen. After excision of the nodule, his azathioprine was withheld. He is currently alive and well without evidence of disease.

The classification of urothelial neoplasms of the kidney traditionally has been similar to that of urinary bladder tumors. Several years ago, the classification of papillary urothelial neoplasms was revised. The current study focuses on the application of the 1998 World Health Organization (WHO)/International Society of Urological Pathology classification system to 102 renal pelvic urothelial neoplasms and compares it to the 1973 WHO classification scheme. In this study, all tumors were classified as urothelial carcinomas, and the majority (85%) were papillary. Most patients with papillary tumors presented with 'superficial' disease (< or = pT1). With the 1998 system, most papillary carcinomas were high grade, and were more often invasive as compared to low-grade tumors. Only 34% were low-grade papillary tumors and, of these, most (93%) were noninvasive. With the 1973 system, most papillary tumors were grade 2 or 3, with invasion more common in grade 3 tumors. By 1973 criteria, grade 2 tumors were a heterogeneous group; with 1998 criteria, nearly one-half were high grade and the other half low grade. The grade of papillary urothelial carcinomas with both the 1973 and 1998 grading methods was associated with stage (P=0.001). Our study reveals that papillomas and papillary urothelial neoplasms of low malignant potential are uncommon tumors in the kidney. Renal pelvic papillary urothelial neoplasms are most often carcinomas and are more commonly high grade than low grade. Although both the 1973 and 1998 systems showed a significant association with tumor stage, grade 2 papillary carcinomas are a heterogeneous group by 1973 criteria. The 1998 system provides useful information in that it more clearly defines a papillary tumor's grade and selects for a group of tumors, namely low-grade papillary urothelial carcinomas, for which a low likelihood of invasion can be predicted.

Tumor-associated carbohydrate antigens are typically perceived as inadequate targets for generating tumor-specific cellular responses. Lectin profile reactivity and crystallographic studies demonstrate that MHC class I molecules can present to the immune system posttranslationally modified cytosolic peptides carrying O-beta-linked N-acetylglucosamine (GlcNAc). Here we report that a peptide surrogate of GlcNAc can facilitate an in vivo tumor-specific cellular response to established Meth A tumors that display native O-GlcNAc glycoproteins on the tumor cell surface. Peptide immunization of tumor-bearing mice had a moderate effect on tumor regression. Inclusion of interleukin 12 in the immunization regimen stimulated complete elimination of tumor cells in all of the mice tested, whereas interleukin 12 administration alone afforded no tumor growth inhibition. Adoptive transfer of immune T cells into tumor-bearing nude mice indicates a role for CD8+ T cells in tumor regression. This work postulates that peptide mimetics of glycosylated tumor rejection antigens might be further developed for immune therapy of cancer.
