A transoral endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is a well-established tissue-sampling method. However, performing a transanal EUS-FNAB remains challenging. Uterine morcellation has emerged as a minimally invasive approach for benign tumor treatment. ⋯ We herein report a rare case of intrapelvic tumor diagnosed by a transanal EUS-FNAB as a recurrence of smooth muscle tumors of uncertain malignant potential following uterine morcellation. Physicians should be aware that a previous uterine myoma resected under morcellation has the possibility of intra-abdominal recurrence. A transanal EUS-FNAB is a practical option for making a pathological diagnosis.

Case Reports
Schnitzler Syndrome Presenting as a Fever of Unknown Origin with Elevated Alkaline Phosphatase Levels.
Schnitzler syndrome (SchS) is a rare, acquired, autoinflammatory disease that is sometimes associated with a fever of unknown origin (FUO). Elevated alkaline phosphatase (ALP) stemming from abnormal bone remodeling is a characteristic laboratory finding of SchS and is included in the diagnostic criteria. However, its utility as a clue to the diagnosis of SchS has been under-emphasized. We herein report a case of SchS presenting with a FUO and highly elevated ALP concentration, which led to repeated, unnecessary liver biopsies.

Objective Muscle atrophy is observed in a subset of patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Its manifestation is associated with a poor functional prognosis and poor response to immunomodulatory therapies. We evaluated muscle atrophy in patients with CIDP using a bioelectrical impedance analysis (BIA). ⋯ A comparison of the outcomes from these two measures showed a good correlation between their muscle atrophy ratings (p<0.05). Conclusion We found that a BIA and muscle CT provided muscle atrophy assessments of equivalent accuracy. Therefore, a BIA can be a simple alternative to muscle CT that is suitable for regular use in daily clinical practice as a reliable tool for assessing muscle atrophy in patients with CIDP.

Severe Enteritis after Cyclophosphamide Administration in a Patient with Microscopic Polyangiitis: A Case Report and Literature Review.
Severe enteritis is a rare side effect of cyclophosphamide (CPA) therapy, and only two cases have been reported to date. We herein report a 60-year-old man who developed severe enteritis after intravenous CPA administration for microscopic polyangiitis. ⋯ A diagnosis of CPA-associated enteritis was made based on the clinical course and imaging and pathological findings. This review of three cases of CPA-related enteritis, including our case, suggests that prompt CPA discontinuation and intensive systemic management are necessary when patients have gastrointestinal symptoms after CPA administration.
