INTRODUCTION Primary malignant melanoma of the esophagus is a rare tumor representing only 0.1-0.2% of esophageal malignancies. The goal of the study was to report on the management of a new case diagnosed and treated in our site. CASE REPORT A 67-year-old patient presented with dysphagia to solids with no other remarkable history or associated skin lesions. He underwent gastroscopy, which re...
Primary malignant melanoma of the esophagus is an extremely rare disease with non-specific clinical presentations and radiological findings. We are presenting a case of 40 years old female admitted to the hospital complaining of dysphasia and weight loss. Esophagoscopy revealed an irregular fungating mass at the lower one third of the esophagus. The tumor was diagnosed provisionally as poorly d...
Although esophageal cancer is highly heterogeneous and the involvement of epigenetic regulation of cancer stem cells is highly suspected, the biological significance of epigenetically modified molecules that regulate different subpopulations remains to be firmly established. Using esophageal cancer cells, we investigated the functional roles of the H3K4 demethylase Jumonji/Arid1b (Jarid1b) (Kdm...

Primary malignant melanoma of the esophagus (PMME) is a rare malignant neoplasm of the esophagus. In the majority of cases, the disease originates in the mucosal layer of the esophagus, which is similar to other types of esophageal cancer. With the development of endoscopic submucosal dissection (ESD), endoscopic resection is possible for cases in which melanomas are limited to the mucosal and ...
BACKGROUND Pilot studies have estimated cancer incidence in patients with systemic lupus erythematous (SLE). However, the results have been inconclusive. To ascertain the correlation between SLE and malignancy more comprehensively and precisely, we conducted a meta-analysis. METHODS PubMed, the Cochrane Library and Embase databases through June 2014, were searched to identify observational st...
Plasmacytoid variant of melanoma is reported in only rare cases. We present the case of a 54-years-old man admitted for enlarged lymph nodes in the lumbar region. Initial diagnosis of plasmablastic lymphoma/plasma cell myeloma was considered. At our institute, a bladder polyp was removed. Microscopic exam demonstrated dense plasmacytoid cells infiltration with pigment deposits. Immunohistochemi...
The author reviewed 950 cases of consecutive esophageal biopsies in the last 15 years in out pathology laboratory of our hospital. There were 223 malignant lesions (23.5%). The number and frequency (percentages) were as follows: 54 mild dysplasia (5.7%), 30 moderate dyplasia (3.2%), 32 severe dysplasia (3.4%), 13 carcinoma in situ (1.4%), 71 squamous cell carcinoma (7.5%), 7 primary adenocarcin...
A 66-year-old man presented to his previous physician with epigastric discomfort in 2014. He was then referred to our hospital due to suspected primary malignant melanoma of the esophagus (PMME). A biopsy showed atypical cells containing melanin granules. A diagnosis of PMME was thus made. We investigated the endoscopic findings of the previous physician, which revealed a black point-like pigme...
