Mucinous adenocarcinoma arising from a complex perianal fistula: a diagnostic and therapeutic challenge.

We present a case of a 64-year-old male with a history of perianal abscesses that have been surgically treated on 10 occasions. Eight months after the last drainage procedure, he presented with a new abscess. Drainage was performed, revealing a cavity with smooth walls, a chronic appearance, filled with mucoid material.

Allogenic stem cells for Crohn's anal fistulas: Treating early improves the deep remission rate.

Aim: The aim of this study was to evaluate the real-life clinical and radiological efficacy of darvadstrocel injection into complex perianal fistulas in Crohn's disease. Secondary endpoints were to assess symptomatic efficacy, adverse effects and factors associated with complete combined clinical-radiological response (deep remission).

Methods: After marketing the product in France, all first patients treated consecutively were included.

Cyclic Neutropenia Mimicking Crohn's Disease: Two Case Reports and a Narrative Review.

Cyclic neutropenia is a rare hematological condition characterized by periodic fluctuations in neutrophil counts, with a 21-day periodicity. Clinical presentation varies from mild to severe forms of the disease, with the onset of recurrent fever, painful oral ulcers, recurrent bacterial infections, peritonitis, and septic shock. The availability of granulocyte colony-stimulating factor (G-CSF) has revolutionized the management and natural history of this disease, regulating the proliferation, differentiation, and maturation of the progenitor cells, and reducing the duration of neutropenia.

Perianal Endometriosis: An Uncommon Site for a Common Problem.

Endometriosis is the presence of uterine glands and stroma outside of the uterus. It is highly prevalent in women of reproductive age. It is usually found in the pelvis, with most cases being found on the peritoneum, ovaries, or deep in the pelvis.

Hidradenitis Suppurativa in Children and Adolescents: An Update on Pharmacologic Treatment Options.

Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory skin condition that manifests as painful, deep-seated, inflamed nodules and abscesses in the axillary, groin, perianal, perineal, and inframammary regions. The associated pain, malodour, and disfigurement contribute to its profound negative impact on psychosocial spheres and overall quality of life in affected individuals. Although the symptoms of HS classically begin in the second or third decade of life, HS affects children and adolescents as well.

A Case of Fournier's Gangrene: A Rare, Lethal Skin Infection.

Fournier's gangrene (FG) is a rare form of necrotizing fasciitis that is characterized by fascial necrosis of the genitalia or perineum. FG typically results as a complication of genital or anorectal abscess, pressure sore, or surgical site infections. Many patients present with no symptoms, whereas other patients may present with non-specific symptoms such as pain or erythema in the genital or perianal regions.

A case report of anal fistula-associated mucinous adenocarcinoma developing 3 years after treatment of perianal abscess.

Background: A long-standing (over 10 years) anal fistula is considered a fundamental cause of fistula-associated mucinous adenocarcinoma (FAMC). Perianal abscesses and anal fistulas are two sequential phases of the same anorectal infectious process. We experienced a case of FAMC which developed 3 years after the treatment of a perianal abscess.

Perianal abscess in children: an evaluation of microbiological etiology and the effectiveness of antibiotics.

Purpose: We aimed to evaluate the demographic characteristics of children with perianal abscess, distribution of microbiological etiology, antibiotic susceptibility, and identify the effectiveness and coverage of antibiotics due to culture results.

Methods: A retrospective study was designed to evaluate pediatric patients with perianal abscesses between January 2013 and December 2022.

Results: A total of 197 episodes in 135 patients were evaluated.

Targeting Metabolic Syndrome in Hidradenitis Suppurativa by Phytochemicals as a Potential Complementary Therapeutic Strategy.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by the appearance of painful inflamed nodules, abscesses, and pus-draining sinus tracts in the intertriginous skin of the groins, buttocks, and perianal and axillary regions. Despite its high prevalence of ~0.4-1%, therapeutic options for HS are still limited.

Preoperative Assessment of Perianal Fistulas with Combined Magnetic Resonance and Tridimensional Endoanal Ultrasound: A Prospective Study.

Background: we designed a prospective study of diagnostic accuracy that compared pelvic MRI and 3D-EAUS with pelvic MRI alone in the preoperative evaluation and postoperative outcomes of patients with perianal fistulas.

Methods: the sample size was 72 patients and this was divided into two imaging groups. MRI alone was performed on the first group.

A 40-Year-Old Man with Anemia, Proctitis, Rectal Bleeding, and a Perianal Rash Due to Mpox (Monkeypox) Infection.

BACKGROUND A recently described zoonotic viral infection, mpox (monkeypox), is an Orthopoxvirus transmitted by close contact, which causes symptoms similar to smallpox, although less severe. This report presents the case of a 40-year-old man with anemia, proctitis, rectal bleeding, and a perianal rash due to mpox infection. CASE REPORT A 40-year-old man with a medical history of human immunodeficiency virus (HIV) and syphilis presented multiple times with progressive and painful perianal lesions.

Chinese expert consensus on standardized treatment for presacral cysts.

Presacral cysts are cystic or cyst-solid lesions between the sacrum and rectum, almost involving adjacent pelvic floorstructures including sacrococcygeal fascia, rectum, and anal sphincter. Presacral cysts are usually benign, currently believed to arise from aberrant embryogenesis. Presacral cysts are clinically rare and the true incidence is unknown.

Typical MR features and interpretation of perianal fistulas in patients with Crohn's disease.

Perianal fistulas in Crohn's disease (CD) are a poor prognostic phenotype requiring a combination of medical and surgical management. Perianal fistulas in CD are characterized by more complex and multi-branched fistulas, association with skin tags, and frequent presence of proctitis. A comprehensive approach with clinical examination, endoscopic and MR assessment is required, and in particular, MR interpretation provides detailed information on the type of fistula with its internal component and activity, secondary tracts and extension, internal, external openings, associated abscess, and presence of proctitis.

New Perianal Sepsis Risk Score Predicts Outcome of Elderly Patients with Perianal Abscesses.

Antibiotic therapy following surgical perianal abscess drainage is debated, but may be necessary for high-risk patients. Frailty has been shown to increase the risk of unfavorable outcomes in elderly surgical patients. This study aims to identify high-risk patients by retrospectively analyzing a single-center cohort and using a pretherapeutic score to predict the need for postoperative antibiotics and extended nursing care following perianal abscess drainage surgery.

Kawasaki disease with peritonsillar abscess as the first symptom: A case report.

Background: Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome, is an acute, self-limiting vasculitis of unknown aetiology that mainly involves the medium and small arteries and can lead to serious cardiovascular complications, with a 25% incidence of coronary artery aneurysms. Periton-Sillar abscesses are a rare symptom of KD and is easily misdiagnosed at its early stages.

Case Summary: A 5-year-old boy who presented to a community hospital with a 3-d fever, difficulty in opening his mouth, and neck pain and was originally treated for throat infection without improvement.

Growth Failure and Primary Amenorrhea: Endocrine Dysfunction as a Late Presentation of Crohn's Disease.

Crohn's disease (CD) is a chronic inflammatory bowel disease involving entire gastrointestinal tract, most commonly affecting terminal ileum and colon. It usually presents with gastrointestinal symptoms like bloody diarrhea, fever and loss of weight. The clinical course of CD includes gastrointestinal complications like fistulas, abscesses and perianal disease.
