Tailgut cysts, also known as retrorectal cystic hamartomas, are rare developmental abnormalities that typically occur in the retrorectal space. They are believed to arise from remnants of the embryonic hindgut (Hjermstad and Helwig, 1988). They can present as incidental findings during routine examination but over half of patients are thought to present with symptoms. MRI has become the modalit...

Folliculosebaceous cystic hamartoma (FSCH) is a distinct type of cutaneous hamartoma of pilosebaceous origin that usually occurs on the face. For FSCH, other parts have been reported such as the genital area, and the trunk. A 50-year-old woman presented with an asymptomatic dome-shaped scalp nodule. The clinical diagnosis was pilar cyst or tumor. Histopathological assessment showed FSCH with ab...

Folliculosebaceous Cystic Hamartoma (FSCH) is a cutaneous hamartoma comprised of follicular, sebaceous and mesenchymal elements, and usually occurring during adulthood. Congenital and childhood presentations of this lesion are exceedingly rare. We describe herein a case of congenital FSCH on the midline and posterior region of the neck in a 1-year-old male infant and highlight the clinico...

A 16-year-old girl was transferred to the department of thoracic and cardiovascular surgery because of a spontaneous pneumothorax with prolonged air leakage. Chest computed tomography demonstrated a cystic lesion measuring 2×3 cm and involving the left upper lobe. Left upper lobectomy was performed via video-assisted thoracoscopic surgery. A pathologic examination of the specimen revealed a mes...

A 23-year-old man with a history of tuberous sclerosis presented multiple white globular elevated lesions bilaterally (Fig A). The most prominent these astrocytic hamartomas in his left eye was raised, cystic, and calcific A, line). En face OCT infrared scan B) highlights the clear cystic spaces. Angiographic flow C) en angiography D) demonstrates plexus capillary vessels apex hamartoma. (Magni...

A pancreatic hamartoma is a rare benign lesion that may be mistaken for malignancy. A pancreatic hamartoma can present with vague, non-specific symptoms, which can be difficult to diagnose despite modern diagnostic tools. We report here a pancreatic hamartoma diagnosed after surgical resection. A 52-year-old female presented with postprandial abdominal discomfort. Abdominal computed tomography ...

Retrorectal cystic hamartomas are rare congenital presacral lesions and malignancy is extremely rare. Although surgical excision is the essential for treatment, a unique feature of our case compared with previously reported tailgut cysts is that this patient's blood irregular antibodies are positive with higher operational risks.A 44-year-old woman presented to our department complaining of pel...

A 68-year-old Japanese woman presented with a solitary pedunculated polyp in the duodenum. Endoscopic ultrasonography showed multiple cystic structures in the polyp. The polyp was successfully resected by endoscopic snare polypectomy and pathologically diagnosed as Brunner's gland hamartoma. Because hamartomatous components were not identified in the stalk of the polyp, we speculate that the st...
