Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome in which secretes high molecular weight (“big”) IGF-2, causing hypoglycemia. Big IGF-2 product of abnormal processing precursors with defective gene transcription and expression. Tumors involved are usually mesenchymal, vascular, or epithelial origin have burden. We report an unusual case NICTH patient concomitant spind...

Abstract Background Leiomyoma is a benign fibromuscular neoplasm originating from smooth muscle cells. Paraurethral leiomyoma an extremely rare, benign, hormone-dependent growth the mesenchymal cells in paraurethral space of female urethra. They usually appear reproductive age group women, mean presentation being approximately 41 years. Case A 48-year-old woman presented with palpable mass at v...

Embryonal rhabdomyosarcoma (ERMS) of biliary tree is a rare type of mesenchymal neoplasm diagnosed at surgery or by preoperative liver biopsy. We present a one year eight months old child who mimicked a choledochal cyst and was eventually treated with surgery, chemotherapy with IRS IV protocol and adjuvant postoperative radiotherapy to surgical bed with 6 MV photons to a dose of 5040 cGy in 28 ...

Solitary fibrous tumour (SFT) is a rare, spindle-cell, mesenchymal neoplasm with haemangiopericytoma-like branching vascular pattern. The tumour has been reported in various locations but the oral cavity is a distinctly uncommon region. We describe a case of solitary fibrous tumour (SFT) in the tongue of a 15-year-old girl. Microscopically it had features characteristic for SFT and a common imm...

A one-year-old girl with a giant cell fibroblastoma (GCF) of the skin in the left arm is described. The tumor presented as a small, asymptomatic, subcutaneous mass that enlarged relatively slowly. GCF is a rare mesenchymal tumor occurring predominantly in young children. Its unique histopathological feature can lead to a misdiagnosis as sarcoma very easily. We review briefly the clinical and pa...

Patients with Beckwith-Wiedemann syndrome (BWS) are known to be at an increased risk for childhood malignancies, particularly Wilms tumor and hepatoblastoma. We report a case of genetically confirmed BWS in a 5-month-old girl who presented with a 9.5-cm abdominal mass associated with elevated α-fetoprotein levels. The clinical impression was strongly suggestive of hepatoblastoma. Histologic exa...

Primary undifferentiated embryonal sarcoma of liver is an extremely rare pathologic entity in the adult population. An unusual case is reported of a 44-year-old female who presented with multiple hepatic cysts and peripheral eosinophilia, initially thought to be hydatid disease of the liver. Angiogram revealed neovascularization. Surgical biopsy showed an anaplastic mesenchymal neoplasm. Pathol...

Angiomyxolipoma is considered a very rare subtype of lipoma, with the latter being the most common type of mesenchymal neoplasm. Only 17 cases have been described in English medical literature. Angiomyxolipomas have been described in many locations, mostly in the subcutaneous tissue. In this report, we present the first case of renal angiomyxolipoma ever encountered. Diagnosis was made after ma...

Glioblastoma, the most frequent primary brain tumor and the most malignant neoplasm, can have the most heterogeneous morphological presentation. Along with classical morphological features, areas of oligodendroglial component and mesenchymal differentiation may be seen. The present case was a rare case of glioblastoma presenting with sarcomatous and oligodendroglial components. The case was dia...

Solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm that arises primarily from the pleura, but recognized also in other tissues. SFT in the thyroid gland is extremely rare. Here we presented the second reported SFT arising in an intrathoracic goiter. The88-year-old woman was referred with a huge goiter involving upper mediastinum accompanied by airway obstruction and tracheostomy. ...
