Solitary fibrous tumour of the sigmoid colon mesentery.

Solitary fibrous tumours (SFTs) are rare tumours arising from mesenchymal tissues. Despite of their more frequent occurrence in the pleura, SFT can present anywhere in the body. Only a few cases have been described arising from the mesentery.

Progressive left lower extremity weakness in a patient with multiple myeloma: A diagnostic dilemma.

Extramedullary plasmacytoma is a type of plasma cell dyscrasia that can present as solitary tumor or secondary to multiple myeloma. We experienced a case of intramuscular plasmacytoma in the left thigh muscles of a patient secondary to multiple myeloma. A 73-year-old male with relapsed multiple myeloma and bilateral hip arthroplasty complained of lxeft lower limb weakness and hip pain 3 months after relapse.

Adolescent Female With Turner's Syndrome and 46,X,der(Y) del(Y)(p11.2)del(q11.2) Karyotype With Gonadoblastoma and Dysgerminoma.

Gonadal dysgenesis patients with Y chromosomal material are subject to increased risk for germ cell tumors. We report a case of an adolescent female presenting with Turner-like syndrome with primary amenorrhea and Tanner stage 1 breast development. Karyotype showed one X chromosome and a minute pericentromeric fragment of Y chromosome without any functional Y genes in all the cells, unlike a mosaic pattern, represented as 46,X,der(Y)del(Y)(p11.
