Primary Squamous Cell Carcinoma of the Liver Initially Presenting with Pseudoachalasia

Pseudoachalasia secondary to primary squamous cell carcinoma (SCC) of the liver is extremely rare and has not been reported until now. Here, we report a unique case of primary SCC of the liver initially presenting with progressive dysphagia along with short periods of significant weight loss. A 58-year-old man initially presented with progressive dysphagia along with significant weight loss over brief periods of time. The radiographic and manometric findings were consistent with achalasia. Subsequent esophagogastroduodenoscopy revealed a moderately dilated esophagus without evidence of neoplasm or organic obstruction. However, firm resistance was encountered while traversing the esophagogastric junction (EGJ), although no mucosal lesion was identified. Due to the clinical suspicion of the presence of a malignant tumor, endoscopic ultrasonography (EUS) and computed tomography scans of the chest and abdomen were obtained. A huge hepatic mass with irregular margins extending to the EGJ was found. EUS-guided fine-needle aspiration was performed, and the mass was diagnosed as a primary SCC of the liver by immunohistochemical staining

Characterization of the complete mitochondrial genome of the white grouper Epinephelus aeneus (Perciformes, Serranidae) and a comparative analysis with other Serranidae species

The complete mitochondrial genome of the white grouper Epinephelus aeneus, which belongs to the family Serranidae, was determined. The complete mitochondrial genome measured 16,578 bp in length and consisted of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. The mitochondrial gene arrangement of E. aeneus was typical of vertebrates. Phylogenetic analysis conducted using the mitochondrial genomes of 13 related species showed that E. aeneus clustered with other Serranidae species. This mitochondrial genome provides an important resource for addressing taxonomic issues and developing conservation strategies

Characterization of the complete mitochondrial genome of the fork-tailed threadfin bream, Nemipterus furcosus (Spariformes, Nemipteridae) and phylogenetic analysis

The complete mitochondrial genome of the fork-tailed threadfin bream, Nemipterus furcosus, which belongs to the family Nemipteridae was first determined. The complete mitochondrial genome was 16,882 bp in size and encoded of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. Nemipterus furcosus has a mitochondrial gene arrangement that is typical of vertebrates. Phylogenetic analysis using mitochondrial genomes of 11 related species revealed that N. furcosus formed a well-supported monophyletic group with the other Nemipteridae species. This mitochondrial genome provides a useful information for addressing taxonomic issues

Complete mitochondrial genome of the double-lined fusileer, Pterocaesio digramma (Perciformes, Caesionidae): mitogenome characterization and phylogenetic analysis

The complete mitochondrial genome of the double-lined fusileer, Pterocaesio digramma, which belongs to the family Caesionidae was determined. The complete mitochondrial genome has a length of 16,504 bp and consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. P. digramma has a mitochondrial gene arrangement that is typical of vertebrates. Phylogenetic analysis using mitochondrial genomes of 15 related species revealed that P. digramma formed a well-supported monophyletic group with the other Caesionidae and Lutjanidae species
