INTRODUCTION: There are few cases of synchronous rectal adenocarcinoma revealed by an anal fistula. The diagnosis of synchronous mucinous adenocarcinoma of the recto sigmoid and anal canal remains difficult. The chronic anal fistula can be mistaken as the common manifestation of a benign perianal abscess or fistula. CASE PRESENTATION: We present a rare case of a Greek Caucasian 79year old male patient with anal fistula and a recurrent perianal abscess who subsequently was found to have developed synchronous rectosigmoid and perianal mucinous adenocarcinoma on biopsy...

Inflammatory bowel disease (IBD) is characterized by recurrent or chronic inflammation of the gastrointestinal tract, which results in increased risk of developing cancer. Anorectal malignant melanoma is often misdiagnosed as either hemorrhoids or benign anorectal conditions in inflammatory bowel disease. Therefore, the overall prognosis and survival of IBD are poor. To date, the best treatment strategy remains controversial. Only early diagnosis and complete excision yield survival benefit. Here, we report a 64-year-old woman with ulcerative colitis, who was found to have anal malignant melanoma on routine colonoscopy...

BACKGROUND Dieulafoy's lesion of the anal canal is an uncommon cause of lower gastrointestinal bleeding due to rupture of a submucosal artery. This could be an under-recognized cause of hemorrhagic shock in rare cases. CASE REPORT We present 2 cases admitted with bleeding per rectum and hemorrhagic shock, and both were diagnosed as Dieulafoy's lesion of the anal canal on sigmoidoscopy. One case was treated surgically and the second was managed endoscopically. CONCLUSIONS Dieulafoy's lesion of the anal canal can be a source of massive lower gastrointestinal bleeding...

VATER association is a nonrandom occurrence of congenital malformations: vertebral defects, anal atresia, tracheoesophageal fistula, renal defects, and radial bone anomalies. We report the case of a 19-year-old man with a childhood diagnosis of VATER association, who presented to the motion sickness clinic with severe seasickness. We discuss the clinical and laboratory diagnosis of vestibular pathophysiology, which was confirmed by MRI of lateral semicircular canal and vestibule dysplasia. We suggest the possibility of vestibular involvement as part of the developmental field defect associated with VATER syndrome, which hitherto has rarely been reported...

BACKGROUND: Over the last decade, the causal link between human papillomavirus (HPV) infection and squamous cell carcinoma of the anus (SCCA) has been well described. Because HPV infection in one site is often associated with other sites of infection, it then follows that patients with SCCA may have an increased risk of additional HPV-related cancers. Identifying and targeting at-risk sites through cancer screening and surveillance may help to guide best practices. The current study sought to ascertain sites and risk of HPV-related second primary malignancies (SPMs) in survivors of SCCA...

Multimodal therapeutic strategies combining chemotherapy, radiation therapy and surgery have been shown to be feasible and to have a positive impact on outcomes by decreasing the risk of locoregional recurrence and often by increasing overall survival. The advantages of neoadjuvant chemo(radio)therapy include optimal tumor control combined with better tolerance and compliance to treatment while also increasing the number of candidates for surgery. Whereas indications for neoadjuvant therapy are increasing, its impact on surgical treatment and postoperative outcomes are not well-known...

AIM: We used non-Hirschsprung's disease (HD) Sox10-Venus Transgenic mice (non-HDSV-mice), an endothelin receptor-B knockout mouse model of HD (HD-mice), and C57B6C3 wild controls (C-mice) to identify the correlation between the anorectal line (ARL) and successful transanal pull-through (TAPT). METHODS: In non-HDSV-mice, intestinal neural crest-derived cells can be visualized with Venus,-a green fluorescent protein-without histochemical staining. We exposed the anal canal in each non-HDSV-mouse and marked the ARL directly with red ink...

BACKGROUND: Several chemotherapy molecules, monoclonal antibodies and tyrosine kinase inhibitors, have been linked to Takotsubo cardiomyopathy (TC). CASE PRESENTATION: In this article, we describe the case of a 45-year-old woman who developed TC after receiving an intra-arterial and intra-venous polychemotherapy for locally advanced epidermoid carcinoma of the anal canal. This is the first described case of TC associated with intra-arterial chemotherapy. CONCLUSIONS: A review of the literature points to 5-fluorouracil as the most common molecule associated with TC and highlights the potential risk associated with rechallenging patient with the same drug...

We treated a 64-year-old man for rectal cancer with direct invasion to the seminal vesicles and no distant metastases by complete resection with laparoscopy and transanal minimally invasive surgery (TAMIS). We inserted the TAMIS device into the anal canal to above the anorectal ring and dissected to prostate level. High ligation of the inferior mesenteric artery and vein was performed by standard medial laparoscopy. The sigmoid and descending colon were mobilized, and in the postrectal space, we dissected to the space made by TAMIS...

Hans Peter Dietz
Since its introduction in the early 1990s, endoanal sonography has become the mainstay of morphologic assessment of the anal canal and sphincter, especially for obstetric anal sphincter trauma. Lack of availability of suitable systems and the invasive nature of the method have limited uptake and clinical utility. More recently, exoanal or transperineal/translabial tomographic imaging has been developed as a noninvasive alternative. This pictorial overview aims to introduce the reader to this new diagnostic modality and to demonstrate common findings in asymptomatic and symptomatic women...

Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place applicator and dose planning for prostate, cervix, and anal canal cancers. It can guide placement of brachytherapy catheters for all other sites like breast, skin, and head and neck cancers...

PURPOSE: Although the standard treatment for patients with locally advanced rectal cancer managed by preoperative chemoradiotherapy (CRT) is a radical resection, local excisions are used in highly-selective cases. Recently, transanal minimally-invasive surgery (TAMIS) has emerged as a feasible technique for local excision of midrectal lesions. We assess the feasibility of using TAMIS to treat patients with locally advanced rectal cancer who showed good response to CRT. METHODS: From October 2010 to June 2013, 35 consecutive patients with rectal cancer managed by using preoperative CRT underwent TAMIS...

BACKGROUND: Anogenital warts (AGW) are one of the most prevalent sexually transmitted disease worldwide. Approximately, 90% of AGWs are related to infection by HPV 6 and 11. However, AGW have been associated with infection by multiple genotypes, including HR-HPV, which may be associated with a long-term increased risk of anogenital cancer. OBJECTIVE: This observational prospective epidemiological study aims to estimate the type-specific HPV distribution on incident AGWs in both genders, and additionally to assess the frequency of anal and oral HPV infection in patients with AGWs...
