Hypercalcemia in patients with cancer is a common laboratory finding affecting up to 44% of that patient population. 1,25-Dihydroxyvitamin D3 mediated hypercalcemia is one of the rare mechanisms of this endocrine emergency in cancer patients. It is even rarer for solid organ neoplasms to present with hypercalcemia mediated through the production of 1,25-dihydroxyvitamin D3. We report a case of ...

This is a case report of a 40 year old lady presenting with gastrointestinal stromal tumor of rectum. Gastrointestinal stromal tumors (GIST) tend to present with higher frequency in the stomach (60-70%) and small bowel (20-25%) while colon and rectum represent rare sites. Gastrointestinal stromal tumors of the rectum represent around 5% of all GISTs and 0.1% of all tumours originating in the re...

Gastrointestinal stromal tumors (GISTs) are rare abdominal tumors which arise from the interstitial cells of Cajal in the gastrointestinal tract. Gastric GISTs are the most commonly seen GIST tumors and may grow to a very large size. They are often associated with abdominal pain, anorexia and weight loss. Most of them can be detected by CT. These tumors have been found to harbor mutations in CD...

INTRODUCTION Cystic lesions of the upper abdomen normally develop from pancreatic tissue. The differential diagnoses include neoplastic and non-neoplastic lesions. Pseudocystic tumors that secondarily involve the pancreas are very rare and may lead to diagnostic pitfalls. CASE PRESENTATION A 51-year-old woman and a 65-year-old man, both German, presented with abdominal cystic lesions suspecte...

Gastrointestinal stromal tumor is rare digestive tract mesenchymal tumor, most often in the wall of the stomach. It is a benign neoplasm, but it can become malignant if not treated. We report a case of gastrointestinal stromal tumor that was discovered after abdominal ultrasonography during staging of a patient with primary cutaneous amelanotic melanoma. Mutation in the tyrosine kinase receptor...

Gastrointestinal stromal tumors are mesenchymal tumors of the gastrointestinal tract. They commonly metastasize within the abdominal cavity, particularly to the liver. Less commonly, metastases can be found in the lung or bone. This report describes the first two cases of metastasis to the left ventricle in patients with advanced gastrointestinal stromal tumor.

INTRODUCTION Paraneoplastic syndromes are disorders associated with clinical signs and symptoms caused by substances produced by malignant disease and are not directly related to the physical effects of a primary or metastatic tumor. We describe a patient with gastrointestinal stromal tumor of the stomach accompanied by nephrotic syndrome as paraneoplastic syndrome in whom symptomatic treatment...

astrointestinal stromal tumors (GIST) are solid of the gastrointestinal tract. The stomach is most common site while esophagus least for tumors. cystic Gastrointestinal tumor has never been reported in past. On CT scan a young male patient, we an exophytic structure 2.5 x 2.2 cm along as esophageal duplication cyst then he underwent image-guided biopsy that finally turned out to be on histopath...

Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract. The introduction of a number of small molecule tyrosine kinase inhibitors has revolutionized the management of metastatic disease. Surgery is the mainstay of management for localized disease. Patients with high risk tumors are treated with adjuvant imatinib. We report the rare presentation of a...
