Eccrine syringofibroadenoma (ESFA) is a rare eccrine ductal adnexal tumor. It shows variable presentations as solitary or multiple nodular lesions arranged in different patterns. It is most commonly seen in middle-aged to elderly patients, and most common sites include the extremities. Classic histopathological findings show anastomosing cords and strands of uniform cuboidal cells surrounded by fibrovascular stroma. Herein, we report a case of reactive ESFA which developed on the perianal region of a 31-year-old man.

Review
Magnetic resonance imaging (MRI) depicts infectious foci in the perianal region better than any other imaging modality. MRI allows definition of the fistula, associated abscess formation and its secondary extensions. Accurate information is necessary for surgical treatment and to obtain a decrease in the incidence of recurrence and complications. Radiologists should be familiar with anatomical and pathological findings of perianal fistulas and classify them using the MRI - based grading system. The purpose of this article was to provide an overview for evaluation of perianal fistulas, examples of various fistula types and their classification.

Review
Perianal fistulizing Crohn's disease is a very disabling condition with poor quality of life. Patients with perianal fistulizing Crohn's disease are also at risk of perianal fistula-related squamous cell carcinoma (SCC). Cancer arising at the site of a chronic perianal fistula is rare in patients with Crohn's disease and there is a paucity of data regarding its incidence, diagnosis and management. A systematic review of the literature was undertaken using Medline, Embase, Pubmed, Cochrane and Web of Science. Several small series have described sporadic cases with perianal cancer in Crohn's disease. The incidence rate of SCC related to perianal fistula was very low (<1%). Prognosis was poor. Colorectal disease, chronic perianal disease and HPV infection were possible risk factors. Fistula-related carcinoma in CD (Chron's disease) can be very difficult to diagnose. Examination may be limited by pain, strictures and induration of the perianal tissues. HPV is an important risk factor with a particular carcinogenesis mechanism. MRI can help clinicians in diagnosis. Examination under anesthesia is highly recommended when findings, a change in symptoms, or simply long-standing disease in the perineum are present. Future studies are needed to understand the role of HPV vaccination in preventing fistula-related cancer.

Observational Study
OBJECTIVE
to investigate the prevalence of perianal disease, the associated phenotypical factors, its influence on prognosis and its impact on the use of health resources for patients with Crohn's disease.
METHODS
a unicentric retrospective observational study was performed with 430 patients with Crohn's disease tracked through a monographical consultation of intestinal inflammatory disease. Demographic and phenotypical data of Crohn's disease, pharmacological and surgical treatments, complementary tests carried out and hospital admissions were analyzed. A comparative study between those patients without perianal disease and those with perianal disease was performed, both in simple form and complex form.
RESULTS
the prevalence of perianal disease was 40.2 %, and fistulas and abscesses were the most frequent manifestations. These appearances were associated with an affected rectum and the existence of extra-intestinal manifestations. The patients with perianal disease most frequently required immuno-suppressant and biological treatment, but no further abdominal surgery. Amongst the patients with perianal disease, the need for biologics was more frequent for luminal disease (42.8 % vs 30.7 %). Furthermore, more explorations were needed, aimed at the study of perianal disease and recto-colonoscopies, although more magnetic resonance (MR)/computed tomography (CT) enterographies were not required.
CONCLUSIONS
perianal disease has a high prevalence among patients with Crohn's disease, especially when the rectum is affected. It is associated with a worse prognosis and more frequently requires biological treatments due to perianal and luminal evolution, especially in cases of complex perianal disease. This condition calls for more hospital admissions and complementary tests.

Review
Actinomycosis is a serious suppurative, bacterial infection caused by the gram-positive anaerobic Actinomyces species. Primary perianal actinomycosis is rare and challenging for the colorectal surgeon. We aimed to present our experience and compare this with available literature. All patients with isolated Actinomyces on microbiology reports, between January 2013 and February 2021, were identified and reviewed. Data collection was retrospective based on electronic patient records. The site of infection and treatment strategy were examined. Perianal cases were evaluated in depth. All publications available in the literature were interrogated. Fifty-nine cases of positive actinomycosis cultures were reviewed. Six cases of colonization were excluded. Actinomyces turicensis was the most common organism isolated. Five cases of perianal actinomycosis were identified requiring prolonged antibiotic and surgical therapy. Twenty-one studies, most case reports, published since 1951 were also reviewed. Diagnosis of perianal actinomycosis may be challenging but should be suspected particularly in recurrent cases. Prolonged bacterial cultures in anaerobic conditions are necessary to identify the bacterium. An extended course of antibiotic therapy (months) is required for eradication in certain cases.

Review
Symptomatic perianal disease is common in patients with Crohn's disease (CD), and perianal fistulas represent the primary form of anal involvement. This type of involvement is associated with a poor prognosis and a disabling course. The treatment is challenging and involves both surgical and medical approaches. Despite combined therapy, a significant portion of patients may still require proctectomy to control the symptoms. Consequently, investigating factors that may influence the outcome of perianal disease remains a priority area of research in CD. Nutritional deficiencies are well documented among CD patients with luminal forms of involvement and are closely related to poor clinical outcomes, therapy response, and postoperative complications. As a result, leading guidelines recommend regular nutritional assessment and correction of nutritional deficiencies in patients requiring a surgical approach. Despite these recommendations and the high rate of surgeries among CD patients with perianal disease, there is a shortage of studies addressing the real impact of nutritional status on the course and outcomes of perianal disease. This knowledge gap underscores the importance of further research to understand better and improve the management of perianal CD. This narrative review aims to provide an overview of nutritional status assessment and the influence of nutritional status on the outcomes of patients with perianal CD.

Meta-Analysis
BACKGROUND AND AIMS
Perianal Crohn's disease (pCD) is a potentially severe phenotype of CD. We conducted a systematic review with meta-analysis to estimate cumulative incidence, risk factors, and outcomes of pCD in population-based cohort studies.
METHODS
Through a systematic literature review through March 1, 2021, we identified population-based inception cohort studies reporting cumulative incidence of perianal disease (primarily abscess and/or fistula) in patients with CD. We estimated the cumulative incidence of pCD at presentation and 1-, 5-, and 10-year follow-up, and risk factors for perianal disease and outcomes including risk of major (bowel resection, proctectomy, ostomy) and minor perianal (incision and drainage, seton placement, etc.) surgery.
RESULTS
In 12 population-based studies, prevalence of pCD was 18.7% (95% confidence interval [CI], 12.5%-27.0%) with 1-, 5-, and 10-year risk of perianal disease being 14.3% (95% CI, 7.9%-24.6%), 17.6% (95% CI, 11.3%-26.5%), and 18.9% (95% CI, 15.0%-23.4%), respectively. Approximately 11.5% of patients (95% CI, 6.7%-19.0%) had perianal disease at or before CD diagnosis. Colonic disease location and rectal involvement were associated with higher risk of pCD. Overall, 63.3% of patients (95% CI, 53.3-72.3) required minor perianal surgery and 6.4% of patients (95% CI, 1.8%-20.6%) required major abdominal surgery for pCD. Use of biologic therapy for pCD is common and has steadily increased throughout the years.
CONCLUSIONS
Approximately 1 in 5 patients with CD develops perianal disease within 10 years of CD diagnosis, including 11.5% who have perianal disease at presentation. Approximately two-thirds of patients require perianal surgery, with a smaller fraction requiring major abdominal surgery.

BACKGROUND
Colorectal and perianal surgery encompasses a broad range of procedures to address various pathologies arising from the colon and anorectum. Data regarding the pattern and outcome of colorectal and perianal disorders requiring surgery remains largely unknown in Ethiopia.
METHODS
A descriptive cross sectional one-year review was made and all patients who were admitted and operated for colorectal and perianal disorders were included in the study. Data was collected by chart review and analyzed by SPSS version 23.
RESULT
Colorectal and perianal surgeries accounted for 14.6% of the procedures in the study period. Males constituted the major share of the study population. The mean age for perianal and colorectal pathologies were 39.6±13.7 and 44.8± 16.2 years respectively. Among the colorectal disorders redundant sigmoid was the most common indication for admission 41(34.4%) followed by colorectal neoplasms 38(31.9%) while among the perianal conditions, fistula in ano was the most common pathology accounting for 69(43.4%) of admissions followed by hemorrhoids 35(22%). The overall incidence of post-operative complications in the colorectal and perianal procedure groups was found to be 29(24.4%) and 4(2.5%) respectively. There was no mortality in the perianal group whereas there were 11(9.2%) deaths in the colorectal procedure group.
CONCLUSION
Colorectal surgeries accounted for a fair share of procedures among the other specialty units. The morbidity and mortality associated with colorectal procedures is fairly high and warrants attention.

Review
Crohn's disease is increasingly thought to encompass multiple possible phenotypes. Perianal manifestations account for one such phenotype and represent an independent disease modifier. In its more severe form, perianal Crohn's disease confers a higher risk of a severe and disabling disease course, relapses, hospital admissions and operations. This, in turn, imposes a considerable burden and disability on patients. Identification of the precise manifestation is important, as management is nuanced, with both medical and surgical components, and is best undertaken in a multidisciplinary setting for both diagnosis and ongoing treatment. The introduction of biologic medication has heralded a significant addition to the management of fistulizing perianal Crohn's disease in particular, albeit with modest results. It remains a very challenging condition to treat and further work is required to optimize management in this group of patients.
