Esophageal leukoplakia or epidermoid metaplasia is a rare lesion resembling the commonly found oral leukoplakia. When found, it is typically seen incidentally on endoscopy as a white plaque but rarely it may present as a globus sensation. Histologically, it is seen as epidermal metaplasia with orthokeratosis, closely resembling the skin. Although rare, esophageal leukoplakia is precancerous and may pose a serious threat. We present a unique case of a 61-year-old male with a history of COPD, tobacco, and alcohol dependence presenting with a six-month history of nausea and emesis resulting in poor oral intake despite having an appetite. The patient also reported weight loss. Considering his risk factors for esophageal carcinoma and alarm symptoms, an upper endoscopy was performed that revealed localized white, plaque-like mucosal changes characterized by altered texture in the lower third of the esophagus at 40cm. Biopsy results showed squamous epithelium with orthokeratosis and a prominent granular cell layer. These findings were consistent with esophageal epidermoid metaplasia. The lesion was ablated using argon plasma coagulation and radiofrequency ablation on subsequent endoscopy. The patient reported continued resolution of symptoms with each treatment session. Esophageal leukoplakia may increase the risk for squamous cell carcinoma of the esophagus and should be followed closely. Guidelines on surveillance are yet to be established given the rarity of the disease.

Esophageal leukoplakia refers to a clinical finding of a white patch on the mucous membrane surface that cannot be scraped off. It has been associated with alcohol and tobacco use and chronic acid reflux. An association with squamous cell dysplasia and carcinoma has been reported with potential for malignant transformation warranting endoscopic intervention or surveillance, but no guidelines exist. We present a case of a 77-year-old female with a history of longstanding achalasia requiring multiple Botox injections. After presenting with weight loss, esophageal dysphagia, and acid reflux the patient underwent an esophagogastroduodenoscopy (EGD) showing a 20 mm white plaque in the middle third of the esophagus and histopathology consistent with esophageal leukoplakia. After repeated Botox injection and treatment with PPI and H2 blocker, no findings of esophageal leukoplakia were noted on repeat EGD. With this case, we aim to increase awareness of this rare disease pathology, especially in the setting of underlying achalasia. This case also raises the question if maximum anti-reflux therapy could have a potential benefit in avoiding the recurrence of esophageal leukoplakia.

Thoracic Cancer Oct 2020To investigate oral leukoplakia (OL) and risk of upper gastrointestinal (UGI) cancer deaths in the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort.
BACKGROUND
To investigate oral leukoplakia (OL) and risk of upper gastrointestinal (UGI) cancer deaths in the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort.
METHODS
A total of 3318 subjects with esophageal squamous dysplasia enrolled on 1 May 1985, and were followed up until 30 September 2015. Participants with OL at baseline were treated as an exposed group, while the remainder was selected as a control group. All subjects were followed monthly and reviewed quarterly by the Linxian Cancer Registry. Cox proportional hazard model was used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs).
RESULTS
During the 30-year follow-up, a total of 902 UGI cancer deaths occurred, including 541 esophageal squamous cell carcinoma (ESCC) related, 284 gastric cardia carcinoma (GCC) related, and 77 gastric noncardia carcinoma (GNCC) related deaths. Relative to subjects without OL, the long-term risk of ESCC mortality in participants with OL increased by 26.1% (HR = 1.26, 95% CI: 1.05-1.52). In the subgroup analyses, adverse effects of OL on ESCC mortality were observed especially in younger subjects (HR = 1.48, 95% CI: 1.11-1.97), females (HR = 1.44, 95% CI: 1.11-1.89), non-smokers (HR = 1.44, 95% CI: 1.15-1.81), nondrinkers (HR = 1.28, 95% CI: 1.04-1.57), and individuals with a family history of cancer (HR = 1.37, 95% CI: 1.05-1.79). No associations were observed between OL and risk of GCC and GNCC mortality.
CONCLUSIONS
OL may increase the long-term risk of ESCC mortality, especially in younger subjects, females, nondrinkers, non-smokers, and subjects with a family cancer history. Future studies are needed to explore the potentially etiological mechanism.

There are no studies of oral health in relation to esophageal cancer in Africa, or of Eastern Africa's endemic dental fluorosis, an irreversible enamel hypo-mineralization due to early-life excessive fluoride intake. During 2014-18, we conducted a case-control study of squamous cell esophageal cancer in Eldoret, western Kenya. Odds ratios (AORs (95% confidence intervals)) were adjusted for design factors, tobacco, alcohol, ethnicity, education, oral hygiene and missing/decayed teeth. Esophageal cancer cases (N = 430) had poorer oral health and hygiene than controls (N = 440). Compared to no dental fluorosis, moderate/severe fluorosis, which affected 44% of cases, had a crude OR of 20.8 (11.6, 37.4) and on full adjustment was associated with 9.4-fold (4.6, 19.1) increased risk, whilst mild fluorosis (43% of cases) had an AOR of 2.3 (1.3, 4.0). The prevalence of oral leukoplakia and tooth loss/decay increased with fluorosis severity, and increased cancer risks associated with moderate/severe fluorosis were particularly strong in individuals with more tooth loss/decay. Using a mswaki stick (AOR = 1.7 (1.0, 2.9)) rather than a commercial tooth brush and infrequent tooth brushing also independently increased risk. Geographic variations showed that areas of high esophageal cancer incidence and those of high groundwater fluoride levels have remarkably similar locations across Eastern Africa. In conclusion, poor oral health in combination with, or as a result of, high-altitude susceptibility to hydro-geologically influenced dental fluorosis may underlie the striking co-location of Africa's esophageal cancer corridor with the Rift Valley. The findings call for heightened research into primary prevention opportunities of this highly fatal but common cancer.

Review
Gastrointestinal complications are frequent in renal transplant recipients and can include oral lesions, esophagitis, peptic ulcer, diarrhea, colon disorders and malignancy. Oral lesions may be caused by drugs such as cyclosporine and sirolimus, by virus or fungal infections. Leukoplakia may develop in patients with Epstein-Barr virus (EBV) infection. The commonest esophageal disorder is represented by fungal esophagitis usually caused by candida. A number of patients may suffer from nausea, vomiting and gastric discomfort. These disorders are more frequent in patients treated with mycophenolate mofetil (MMF). Peptic ulcer is more rare than in the past. Patients with a history of peptic ulcer are particularly prone to this complication. Other gastroduodenal disorders are caused by cytomegalovirus (CMV) and herpes simplex infection. Diarrhea is a frequent disorder which may be caused by pathogen microorganisms or by immunosuppressive agents. The differential diagnosis may be difficult. Colon disorders mainly consist of hemorrhage, usually sustained by CMV infection, or perforation which may be caused by diverticulitis or intestinal ischemia. Colon cancer, anal carcinoma, and EBV-associated lymphoproliferative disorders are particularly frequent in transplant recipients. A particular gastric lymphoma called mucosa-associated lymphoid tissue (MALT) lymphoma may develop in renal transplant patients. It usually responds to the eradication of Helicobacter pylori.

Dyskeratosis congenita (DC) is an inherited disease characterized by the triad of abnormal skin pigmentation, nail dystrophy and mucosal leukoplakia. Non-cutaneous abnormalities (dental, gastrointestinal, genitourinary, neurological, ophthalmic, pulmonary and skeletal) have also been reported. Bone marrow failure (BMF) is the main cause of early mortality, with an additional predisposition to malignancy. DC results from an anomalous progressive shortening of telomeres resulting in DNA replication problems inducing replicative senescence. Men are more affected than women are and X-linked recessive, autosomal dominant and autosomal recessive forms of the disease are recognized. There are no targeted therapies for DC. Patients treated with androgens had a hematological response. We herein describe case of a 32-year-old man, presented with several characteristic systemic features of this condition, including the classic triad of lesions, dysplastic bone marrow, epiphora and liver cirrhosis with grade I esophageal varices. Therefore, a prophylactic propranolol was started in additional to danazol. Three-week later, the patient had subsequent increases in his platelet, red cell and white cell counts.

Diffuse esophageal hyperkeratosis (DEH) is a very intriguing and impressive mucosal finding that is quite easily identified on endoscopy and histology. A distinction must be made between microscopic/focal hyperkeratosis and endoscopically visible DEH. Microscopic hyperkeratosis is not uncommon in histological studies, while diffuse hyperkeratosis is seen very rarely. Over the past century, only a handful of cases have been reported. The endoscopic appearance of hyperkeratosis is of thick, white, piled-up mucosa. On histology, there is a prominent thickening of the stratum corneum, the squamous cells are anuclear, and there is no hyperplasia of the squamous epithelium. These histological characteristics distinguish benign orthokeratotic hyperkeratosis from other premalignant entities such as parakeratosis or leukoplakia where hyperplastic squamous cells retain pyknotic nuclei, lack keratohyalin granules, and also lack complete keratinization in superficial epithelial cells. The clinical presentation of hyperkeratosis includes gastroesophageal reflux, hiatal hernia, and associated symptoms. Our case highlights a very rare endoscopic finding associated with a common clinical presentation. The nearly 10-year follow-up reinforces the benign nature of ortho-hyperkeratosis and our report underscores the features that distinguish DEH from premalignant conditions. It merits additional research into factors that lead to hyperkeratinization of the esophageal mucosa as opposed to the more common columnar metaplasia. The concomitant presence of Barrett's esophagus in some patients is even more intriguing. Animal models with variable pH and content of the refluxate may shed light on the role played by duodenogastric/non-acid reflux in this condition. Larger, prospective, multicenter studies may provide the answers.

Oral leukoplakia is a relatively common, painless disorder of the oral mucosa. It predominantly affects middle-aged to elderly men and has a strong association with tobacco smoking and alcohol intake. Concomitant histological findings of hyperorthokeratosis and a well-developed granular cell layer, termed orthokeratotic dysplasia, are often associated with oral squamous cell carcinoma. In contrast, analogous lesions within the esophagus, termed esophageal epidermoid metaplasia, are rarely encountered and poorly described in the literature. To better characterize the clinicopathological features of this entity, we have collected 25 cases from 18 patients. Patients ranged in age from 37 to 81 years (mean, 61.5 years), with a slight female predominance (10/18, 56%). On presentation, a majority of patients complained of dysphagia (10/18, 56%). Past medical history was significant for tobacco smoking or long history of second-hand smoke in 11 (61%) patients and alcohol intake in 7 (39%) patients. Seventeen (94%) patients with esophageal epidermoid metaplasia were located within the middle-to-distal esophagus. Histologically, all cases were sharply demarcated and characterized by epithelial hyperplasia, a thickened basal layer, acanthotic midzone, a prominent granular cell layer, and superficial hyperorthokeratosis. Adjacent high-grade squamous dysplasia and/or squamous cell carcinoma were seen in 3 out of 18 (17%) patients. Follow-up information was available for 13 out of 18 (72%) patients and ranged from 2 to 8.3 years (mean, 2.3 years). Seven of the 13 (54%) patients had persistent disease; however, none of them developed squamous dysplasia or squamous cell carcinoma. In an effort to assess the incidence of esophageal epidermoid metaplasia, 198 consecutive esophageal biopsies were prospectively surveyed over a 6-month period at three academic institutions. No cases were identified within this time frame. In summary, esophageal epidermoid metaplasia is a rare condition affecting the middle-to-distal esophagus in middle-aged to elderly females. The occurrence of adjacent high-grade squamous dysplasia and/or squamous cell carcinoma warrants close follow-up.

BACKGROUND
It is important to better understand the role that environmental risk factors play on the development of esophageal cancer in Howel-Evans families. Additionally, there is little published about appropriate esophageal cancer screening practices in families genetically confirmed to have this condition.
METHODS
Surveys were distributed to 47 addresses of an American family with Howel-Evans syndrome, of which 29 responded and met inclusion criteria. Data was collected about demographics, environmental risk factors, and medical history of participants.
RESULTS
We report characteristics of family members with tylosis, rates of esophageal cancer, rates of genetic counseling, and levels of environmental risk factors. Of the survey respondents, 43% reported features of tylosis, 71.4% were male and 28.6% were female and 28.6% reported leukoplakia. Only 21.4% of tylotic family members smoked, 65% drank alcohol, and 28.6% drank well water. More than half (57.1%) of the tylotic individuals had never had an esophagogastroduodenoscopy (EGD) and no one had been diagnosed with esophageal carcinoma. Only 3.4% of respondents had ever received genetic testing for Howel-Evans syndrome, despite genetic confirmation of their relatives.
CONCLUSIONS
We encourage dermatologists to discuss smoking-cessation, genetic counseling, and early EGD with affected families.
