Refractory Cryptoglandular Perianal Abscess and Fistulas Due to Mycobacterium avium Infection in an Immunocompetent Adult.

is a slow-growing nontuberculous mycobacterium (NTM) requiring prolonged treatment with multiple antimicrobials. It primarily affects immunocompromised patients and causes infection of the respiratory tract, skin, and soft tissue. While enteric carriage of has been reported, it has not been associated with clinical infection in immunocompetent hosts.

Rare confounder: benign multicystic peritoneal mesothelioma in a patient with mucinous colon adenocarcinoma.

Benign multicystic peritoneal mesothelioma (BMPM) is a rare condition, in which patients have multiple cystic lesions of the peritoneum. BMPM can mimic mucinous carcinomatosis and can thus create a diagnostic dilemma. We present the case of a 76-year-old woman who was referred for management of ascending colon adenocarcinoma and was noted to have several nonspecific cystic lesions in the abdomen and pelvis on preoperative computed tomography and diagnostic laparoscopy.

Cutaneous Crohn's disease after proctocolectomy for medically refractory colonic Crohn's disease: a case series and review of the literature.

Background: Cutaneous Crohn's disease (CCD), also known as metastatic Crohn's disease (CD), is one of the rarest and most challenging cutaneous manifestations of CD. It is characterized by non-caseating granulomatous inflammation of the skin at sites that are non-contiguous with the gastrointestinal (GI) tract. Diagnosis of CCD needs a high clinical suspicion since morphological presentation varies widely and lacks an apparent correlation to the activity of the luminal CD.

Serum Depletion of Complement Component 5a Is Associated With Increased Inflammation and Poor Clinical Outcomes in Patients With Perianal Fistulas.

Background: Persistent disease is a significant issue in the management of perianal fistulas, with up to 50% of patients requiring additional treatment after surgery.

Objective: This study aimed to identify a novel prognostic modality in hopes of risk-stratifying patients for persistent disease following corrective surgery.

Design: This was a retrospective study based on prospectively collected data using a combination of histopathology, high-throughput proteomic arrays, and ELISA-based methods.
