Case report: Laparoscopic treatment of gastro-omental hemangioma with hemorrhage: two cases reports and review of literature.

Background: Spontaneous hemorrhage of gastro-omental hemangioma is a rare disease. The treatment strategy for this disease changes as it develops. In the acute stage, surgery is the first priority, among which laparoscopic treatment should be the most frequently considered option in large general hospitals.

Serum Proteomics Combined with Metabolomics Analysis Explore the Molecular Biological Characteristics of Eruptive Syringoma.

Background: Eruptive syringoma (ES) is a clinical variant of the appendageal tumor syringoma. Around 75% of ES arise in the head or neck, which makes them unsightly. ES is common in patients with amyloidosis, diabetes, and Down's syndrome, suggesting that it may be associated with potential systemic effects.

Descending colon cancer in a patient with situs inversus totalis: a case report and literature review.

Situs inversus totalis (SIT) is a congenital disorder of anatomical position, and the operation of patients with total visceral inversion often brings great challenges to surgeons. Although there have been previously documented on patients with SIT and colonic cancer, this is the first case report of descending colon cancer in patient with SIT. The current report presents a case of a 67-year-old female patient with descending colon cancer and SIT.

[Two mutations of the KRT6A gene in Chinese patients with pachyonychia congenita type I].

Objective: To investigate the gene mutation in a Chinese pedigree and one sporadic case with pachyonychia congenita type I(PC-1), as well as to explore the relationship between the genotype and phenotype.

Methods: The whole coding region of the KRT16 and KRT6A genes were amplified by long-range polymerase chain reaction (PCR). Six patients with PC-1 were studied, five of them were from a pedigree and the other one was sporadic.

A novel mutation in the second half of the keratin 17 1A domain in a large pedigree with delayed-onset pachyonychia congenita type 2.

Pachyonychia congenita type 2 (PC-2), also known as Jackson-Lawler type PC, is an autosomal dominant disorder characterized by hypertrophic nail dystrophy associated with focal keratoderma and multiple pilosebaceous cysts. We report a large Chinese pedigree of typical delayed-onset PC-2 that includes 19 affected members. Direct sequencing of PCR products revealed a novel heterozygous 325A-->G mutation in the affected members.

[A novel keratin 17 gene mutation in a Chinese pedigree of delayed-onset pachyonychia congenita type II].

Objective: To detect the keratin 17 gene mutation in a Chinese pedigree of typical delayed-onset pachyonychia congenita type II (PC-II) and to explore the relationship between the genetic mutation and the phenotype of PC-II.

Methods: The DNA was extracted from the blood samples of 19 patients with PC-II in four generations in the pedigree, 1 unaffected member of the pedigree, and 50 un-related normal persons. Nested PCR was used to amplify the mutation hot spot in the exon 1 of keratin 17 gene.
