Abstract PDF: Small-bowel tumors, both benign and malignant, are rare lesions that clinicians often do not encounter, accounting for less than 2% of gastrointestinal malignancies. Usually, benign small-bowel tumors, including polyps, are asymptomatic. The diagnosis of small-bowel tumors is difficult because of an often-delayed presentation and nonspecific signs and symptoms. We report an incidentally detected case of a long, pedunculated, large polyp of the terminal ileum, which protruded through the ileocecal valve into the cecum that was removed by colonoscopy in a 41-year-old male with intermittent right-sided lower-abdominal pain. The polyp was resected through snare polypectomy without complications. The histopathology of the resected polyp was confirmed as an ileal hyperplastic polyp. Two years later, there was no recurrence observed via postpolypectomy surveillance colonoscopy.

Anal gland/duct cyst (AGC) is rare and observed in only 0.05% of patients undergoing anal surgery. AGC is thought to be a retention cyst in the anal gland and arises when an obstruction of the anal duct causes fluid collection in the anal gland. We report a case of AGC in a 66-year-old woman without anal symptoms. Found by colonoscopy, the AGC was excised transanally. The histopathology of the specimen confirmed AGC. Colonoscopists should include AGC in the differential diagnosis of anal canal mass and rule out of malignancy. Excision is recommended for definitive diagnosis and treatment.

Abstract PDF

Hidradenoma papilliferum is a rare benign cystic tumor that originates from apocrine glands or anogenital mammary glands. Here, we describe 2 cases of hidradenoma papilliferum of the anus. Two female patients aged 39 and 35 presented with perianal masses with hemorrhoids. The patients underwent hemorrhoidectomy and excision of the lesion. Histopathology confirmed the masses as hidradenoma papilliferum. The postoperative course was uneventful for both patients, and there were no recurrences after 18 and 12 months of follow-up, respectively. Proctologists should consider hidradenoma papilliferum in their differential diagnosis of benign anal tumors. Surgical excision is necessary for diagnosis and treatment of hidradenoma papilliferum.
