Myeloid sarcoma of the vulva post-bone marrow transplant presenting as isolated extramedullary relapse in a patient with acute myeloid leukemia

Myeloid sarcoma is a tumor of myoblasts or immature myeloid cells occurring in an extramedullary site. Myeloid sarcoma of the female genital tract as an isolated initial presentation or isolated relapse is very rare as evidenced from a literature review. We report a case of vulvar myeloid sarcoma presenting as isolated relapse of acute myeloid leukemia [AML] after allogeneic hematopoietic stem cell transplant [HSCT]. A 41-year-old female diagnosed with AML M5 achieved remission with chemotherapy and underwent allogeneic HSCT from an HLA-matched sibling donor. The post-transplant period was complicated with chronic graft-versus-host disease. At 10 months post-transplant, she presented with a vulvar mass of six weeks duration. Excisional biopsy of the vulvar mass confirmed the diagnosis of myeloid sarcoma as extramedullary relapse. Bone marrow biopsy was without evidence of leukemia. Involvement of the vulva, vaginal and adjacent cervical area only was confirmed. She received re-induction chemotherapy with clinical regression of both the vulvar, vaginal and the cervical masses; this was followed by radiation therapy to an extramedullary site. The correct diagnosis of myeloid sarcoma, particularly of an isolated mass in the genital area, is important because of its rarity and the need for appropriate institution of therapy

Updated recommendations for the diagnosis and management of osteoporosis: a local perspective

Postmenopausal osteoporosis and osteoporosis in elderly men are major health problems, with a significant medical and economic burden. Although osteopenia and osteoporosis are more common locally than in the West, fracture rates are generally less than in Western countries. Vitamin D deficiency is common in the region and contributes adversely to bone health. Vitamin D deficiency should be suspected and treated in all subjects with ostopenia or osteoporosis. The use of risk factors to determine fracture risk has been adopted by the World Health Organization and many international societies. Absolute fracture risk methodology improves the use of resources by targeting subjects at higher risk of fractures for screening and management. The King Faisal Specialist Hospital Osteoporosis Working Group recommends screening for women 65 years and older and for men 70 years and older. Younger subjects with clinical risk factors and persons with clinical evidence of osteoporosis or diseases leading to osteoporosis should also be screened. These guidelines provide recommendations for treatment for postmenopausal women and men older than 50 years presenting with osteoporotic fractures for persons having osteoporosis-after excluding secondary causes-or for persons having low bone mass and a high risk for fracture. The Working Group has suggested an algorithm to use at King Faisal Specialist Hospital that is based on the availability, cost, and level of evidence of various therapeutic modalities. Adequate calcium and vitamin D supplement are recommended for all. Weekly alendronate [in the absence of contraindications] is recommended as first-line therapy. Alternatives to alendronate are raloxifene or strontium ranelate. Second-line therapies are zoledronic acid intravenously once yearly, when oral therapy is not feasible or complicated by side effects, or teriparatide in established osteoporosis with fractures
