- We describe here a case of traumatic neuroma that developed in the pancreas head as a rare complication of pancreatic surgery for pseudocyst. A 50-year-old man presented with septic shock. The patient was a heavy drinker with history of operation for pancreatic pseudocyst 28 years ago. On the radiologic examinations, a poorly defined mass-like lesion was found in the uncinate process of pancreas, and it had features of chronic pancreatitis and a stricture of the distal common bile duct. Whipple's operation was performed due to the diagnosis of suspected pancreas head cancer. The pancreas revealed an ill-demarcated 4 cm sized firm mass with grayish white fibrotic cut surface in the head portion.
On the microscopic examination, the mass was composed of haphazard proliferations of nerve fascicles in a fibrocollagenous matrix and this case was diagnosed as traumatic neuroma. Although traumatic neruoma is a rare cause of a pancreatic mass, it should be included as a differential diagnosis of pancreatic mass in patients with a history of pancreatic surgery.

- Authors report a typical case of congenital fiber type disproportion (CFTD) with unique clinicopathologic characteristics. The patient was a 13-year-old boy who presented with weakness of lower extremities, especially proximal muscle, since his infancy. He has suffered from severe scoliosis which got worse since the age of 12. He showed mild dysarthria, high arched palate, and fish face.
All routine laboratory data were within normal limits. EMG findings suggested myopathy. The muscle biopsy revealed fiber type disproportion with type 1 predominance. While most of the type 1 myofibers were atrophic or normal in size, the type 2 fibers showed universal hypertrophy. The difference of mean diameter between the larger and the smaller fibers was 27.9%. The patient's clinicopathologic settings fulfilled the criteria of CFTD.

Abstract

- Tracheal gaenesis is an extremely rare congenital anomaly and is characterized by totally or partially undeveloped trachea. In many instances, the lesion has been associated with malformations in other organ systems. This anomaly is classified into 3 types based on developmental period of the respiratory tract. We report a case of tracheal agenesis with tracheoesophageal fistula in a 2-hour-old male.
Postmortem examination revealed that the upper and mid portion of the trachea was absent but 1 cm segment of the trachea above the carina was present. The proximal end to this trachea opened to the esophagus by a fistula, 1 cm in diameter. The well-formed larynx ended blindly in a fibrous sac at which thyroids and cartilage islands are noted.
Associated anomalies were bilobed right lung and single umbilical artery.
