Cysts of the liver ligaments are extremely rare and cysts of the ligamentum teres of the liver have been sporadically reported in the literature during the last century. The present report describes a case of a symptomatic patient with a cyst of the ligamentum teres of the liver. The patient presented with right upper quadrant pain and indigestion during the last 2 years. Ultrasound and computed tomography scans revealed a water-density mass attached to the anterior abdominal wall, but definite diagnosis could not be reached. The cyst was completely excised during laparotomy. Cysts of the ligamentum teres of the liver, although infrequent, may produce clinical symptoms and require excision. Ultrasound and computed tomography scan preoperatively cannot rule out malignancy, thus exploratory laparotomy and total resection of these lesions are necessary.

Melanoma accounts for 1-3 per cent of all malignant tumors. Except cutaneous, other less common melanomas include, among others, those in the GI tract. However, their primary or secondary nature is often difficult to establish. Referring to the stomach, scattered cases of primary melanomas have been reported in the literature. We report a case of a man with an ulcerated submucosal mass at the antrum of the stomach, manifested with dull upper abdominal pain, nausea, vomiting, fatigue and anemia. This lesion was histologically proved to be melanoma. A detailed clinical and laboratory investigation revealed no primary site elsewhere. To our knowledge, very few cases of primary gastric melanoma have been reported. Our case is the fourth ever published and the first located at the antrum of the stomach. The debate upon the primitive nature of such lesions still persists. Thus, specific diagnostic criteria have been proposed.

We read with interest the article entitled： ‘Jejuno-jejunal invagination due to intestinal melanoma’ by Resta , et al. They reported a rare clinical case of a young woman with a bleeding jejunal melanoma, whose early clinical presentation was an intestinal invagination. The article is also referred to the rarity of gastrointestinal melanomas as well as their possible primary nature.

Intussusception in adults is rare. The clinical picture of intussusception in adults is subtle and the diagnosis is,therefore,elusive. The presence of a structural abnor- mality in the great majority of the adult cases mandates high clinical suspicion. Gastrointestinal lipomas are rare benign tumors and intussusception due to a gastrointes- tinal lipoma constitutes an infrequent clinical entity. The present report describes a case of jejunojejunal intus- susception in an adult with a history of severe episodes of hematochezia and colicky upper abdominal pain. The diagnosis was suspected preoperatively but computed tomography scan could not rule out malignancy. Explor- atory laparotomy revealed jejunojejunal intussusception secondary to a lipoma which was successfully treated with segmental intestinal resection.
