Gastrointestinal stromal tumours (GISTs), are relatively common tumours of the gastrointestinal tract, most commonly found in the stomach. Previously they were termed as leiomyomas and leiomyosarcomas. Clinically, they are asymptomatic but may cause abdominal pain or bleeding from ulceration of the overlying mucosa. We present a case of gastroduodenal intussusception secondary to large gastric ...

If abdominal tumours in children were symptomatic more often than they are, diagnosis would be simple and indications for management clear. However, abdominal tumours are usually silent. Frequently they are discovered accidentally. They may well be diagnosed by chance in the systematic work-up for apparently unrelated symptoms, as, for example, in a child with a fever of unknown origin who has ...

A 42-year-old male patient was hospitalized for lower leg oedema, shortness of breath and body-weight loss of 5 kg over a 2-month period. Physical examination identified a pale appearance, cachexia, and a palpable abdominal mass of about 20 18 cm in the right abdomen. Ultrasound study verified the existence of a massive right-side abdominal heterogenous tumour. Due to renal failure with severe ...

A middle aged woman referred for an abdominal mass was found to have large amounts of dopa (3-4-dihydroxyphenylalanine) metabolites in her urine. At operation a tumour affecting almost the entire left lobe of the liver was removed. Histologically the tumour was a metastatic carcinoid. After operation the excretion of dopa metabolites fell substantially, confirming that the tumour was the source...

Abstract A 6-year-old unilateral cryptorchid dog presented with episcleral haemorrhage and ecchymosis. The complete blood count was consistent pancytopaenia. Abdominal imaging confirmed the presence of a caudal abdominal mass suspected to be Sertoli cell tumour (SCT) associated myelotoxicity. myelotoxicity induced thrombocytopaenia delay in obtaining serum oestradiol results could make it chall...

Extra-abdominal fibromatosis (desmoid tumour) is a rare aggressive neoplasm with a tendency to infiltrate local structures but rarely metastasises or undergoes spontaneous malignant transformation. The treatment of choice is surgery, however, recurrences have been reported even after wide-field resection. This article presents a case of extra-abdominal fibromatosis that had extensively invaded ...

Leiomyomas are benign soft tissue swellings of smooth muscle origin, most commonly found in the uterus. Extra uterine leiomyomas presenting as an abdominal mass is often a diagnostic challenge as such occurrence is rare. We present a rare case of primary abdominal wall leiomyoma, and highlight the importance of laparoscopic approach in the diagnosis and treatment of such tumour.

The presence of a large bulky pancreatic tumour in a young female should raise suspicions of the diagnosis of solid-pseduopapillary tumour of the pancreas.This rare tumour has the characteristics of a low-grade malignancy with indolent behaviour. Most patients present with vague non-specific abdominal pain resulting in delayed diagnosis. The light microscopic features show solid areas alternati...

rhabdomyosarcoma encompasses a group of malignant myogenic neoplasms expressing a multitude of clinical and pathological diversities. it is the commonest soft tissue sarcoma of childhood but neonates are rarely affected. embryonal subtype is the most frequent. head-neck and genitourinary tracts are predominant sites, while trunk is considered among the unusual sites of rhabdomyosarcoma. herein ...

Gastric teratoma is a very rare tumour that usually manifests as an abdominal mass, resulting in gastrointestinal bleeding and/or obstructive features. We report gastric teratoma occurring in a two-year-old boy who presented with an abdominal mass. Diagnosis was aided by the classical findings of teratoma on computed tomography, seen as the presence of fat, calcifications, and both solid and cy...
