Lateral cervical cyst with unsuspected metastasis from an occult tonsillar carcinoma.

Lateral cervical cysts containing squamous cell carcinoma is a diagnostic and therapeutic challenge for the clinician since they usually represent a cystic metastasis from an occult carcinoma. Various imaging modalities or even blind biopsies will help identify the primary tumour. If the primary tumour is identified, an appropriate treatment decision can be made that incorporates both the primary tumour and the cervical node. If the primary remains unidentified, the neck is treated with a modified or radical neck dissection, depending on the extent of metastatic disease, and radiation therapy is administered to Waldeyer's ring and both necks. We present in this paper, a case with a large cervical cyst where histology showed the presence of a poorly differentiated squamous cell carcinoma in the wall of the cyst. A diagnostic evaluation of the patient was negative. Blind biopsies of the right tonsil revealed occult squamous cell carcinoma. The patient was treated by combined chemo/radiotherapy and she is doing well nine months following excision of the mass. The relevant literature is briefly reviewed.

A case of gallstone ileus with an unusual impaction site and spontaneous evacuation.

Gallstone ileus is an unusual cause of colonic obstruction. The formation of a fistula between the gall bladder and the bowel wall may allow a gallstone to enter the intestinal tract. Plain abdominal films, abdominal ultrasound and abdominal computed tomography aid in the diagnosis. Although surgery is the treatment of choice in cases of colonic gallstone ileus, colonoscopic removal of the impacted stone should be attempted. We describe the case of an 85-year-old man who presented with symptoms and signs of large bowel obstruction. Diagnostic evaluation revealed a large gallstone impacted in the sigmoid colon, which is a rather unusual impaction site. Despite our efforts we could not extract the stone endoscopically, mainly due to its large size. Yet, despite its large size, the stone was spontaneously evacuated a few hours later.

Buried bumper syndrome with a fatal outcome, presenting early as gastrointestinal bleeding after percutaneous endoscopic gastrostomy placement.

Percutaneous Endoscopic Gastrostomy (PEG) has gained wide acceptance among patients who require prolonged tube-feeding support. A rather unusual complication of PEG placement is migration of the internal bumper through or into the abdominal wall. This was first described in 1988 and is called the buried bumper syndrome (BBS). The syndrome is a late complication of PEG tube placement. The manifestations of the syndrome must be recognised and the patient referred for emergency endoscopy and removal of the bumper. Failure to recognise this syndrome may result in serious complications including gastrointestinal bleeding, perforation of the stomach, peritonitis and death. We describe a case where a patient developed the buried bumper syndrome quite early after PEG placement. The syndrome manifested with gastrointestinal bleeding. Although we removed the buried bumper endoscopically, and placed another PEG tube, the patient developed peritonitis and died 16 hours after the removal of the migrated bumper.
