The synchronous or metachronous coexistence of gastrointestinal stromal tumors (GISTs) with solid and hematologic neoplasms has been addressed in a non-transplant population. However, the association with primary hepatic neoplasms and leukemias is uncommon. Scarce data exist considering association of GISTs and other neoplasms in a transplant population where long-term immunosuppression carries...

ISSN 0001-5555 Sir, Paraneoplastic pemphigus (PNP) is an autoimmune bullous disease characterized by severe mucous membrane involvement, polymorphous skin eruptions, and underlying neoplasms. Most cases are associated with lymphoproliferative neoplasms, and solid tumours have rarely been associ...

Of 291 juvenile and adult snakes examined post mortem over a 20-year period (1978-1997) at the National Zoological Park (NZP) in Washington, DC, 36 (24 females and 12 males) had neoplasms. Two snakes had tumours of two or three different types, but the other 34 snakes had only one type. All affected animals were adults and their average time on exhibit at the NZP was 108-9 months. Malignant neo...

The transcription factor LMO2 is involved in vascular and hematopoietic development and hematolymphoid neoplasia. We have demonstrated that LMO2 is expressed nearly ubiquitously in native and neoplastic vasculature, including lymphatics. LMO2 reactivity is otherwise virtually absent in nonhematolymphoid tissues except in breast myoepithelium, prostatic basal cells, and secretory phase endometri...

Abstract Background Gastrointestinal vascular malformations are rare benign neoplasms of the gastrointestinal tract, with rectosigmoid region being most frequently involved site. Patients often manifest recurrent, intermittent rectal bleeding, which might occasionally be life-threatening. Case presentation A 39-year-old man a history hemorrhoid operations twice was presented to our gastroentero...
