Review of current literature on gestational trophoblastic neoplasia.

BACKGROUND: Gestational Trophoblastic Neoplasia (GTN) is a disease of the reproductive age group with an incidence rate of <1% among all tumors involving the female reproductive tract. It occurs because of aberrant fertilization. Patients are diagnosed early because of aggravated symptoms during pregnancy. Moreover, patients also bleed from the tumor sites, which leads to early presentation. A cure rate of 100% can be achieved with adequate treatment. MAIN BODY: In this literature review, the authors have brought to attention the risk factors, classification, and various treatment options in GTN patients according to their stratification as per the WHO scoring system. Patients are categorized into low and high risk based on the FIGO scoring system. Patients with low risk are treated with single-agent methotrexate or actinomycin-D. Despite the superiority of actinomycin-D in terms of efficacy, methotrexate remains the first choice of therapy in low-risk patients due to its better toxicity profile. Multi-agent chemotherapy with etoposide, methotrexate, actinomycin-D, cyclophosphamide and vincristine (EMA-CO) leads to complete remission in 93% of high-risk GTN patients. Around 40% of patients with incomplete responses are salvaged with platinum-based multi-agent chemotherapy. Isolated chemo-resistant clones can be salvaged with surgical interventions. CONCLUSION: The mortality in patients with GTN has significantly reduced over time. With adequate multi-disciplinary support, patients with GTN can ultimately be cured and can spend every day healthy reproductive life.

Multiple myeloma and its rare paraneoplastic manifestations simmering under the surface.

Paraneoplastic syndromes are complex clinical manifestations that occur because of the underlying malignancy in which the malignant cells produce hormones, cytokines, peptides or antibodies that causes symptoms and may affect multiple organ systems. These paraneoplastic conditions may be associated with different solid and hematological malignancies. Multiple Myeloma (MM) accounts for 10-15 % of hematological malignancies and 1-2 % of all malignancies. It is associated with some atypical clinical and laboratory paraneoplastic manifestations. Although there is a low incidence of these paraneoplastic, significant knowledge of these manifestations may assist in making a differential diagnosis in cases of doubt. The clinical presentation may vary and be evident even before or after the diagnosis of malignancy. These include vascular, neurological, dermatological, physiological, and other atypical conditions. Furthermore, these rare paraneoplastic manifestations need more valid, relevant scientific information, as most information about these conditions is derived from case reports. After the literature search, we have reported the paraneoplastic manifestations associated with multiple myeloma, published in the English literature, and the cognate management in this review article. To our knowledge, this is the first review article discussing various paraneoplastic manifestations of multiple myeloma.

Bilateral congenital cryptorchidism and unilateral Leydig cell tumor in an adult presenting with gynecomastia and primary infertility: A case report.

INTRODUCTION AND IMPORTANCE: The neoplasms of the testis are sporadic tumors among men. Furthermore, the rarest subset of these is neoplasms belonging to the stromal tumors of the sex cord. Leydig cell tumors are the most common form among the testicular stromal tumors. In our case, the underlying risk factor associated with the development of Leydig cell tumors was cryptorchidism. While mostly unilateral, cases of bilateral cryptorchidism may be present and have been rarely reported. CASE PRESENTATION: We report a 36-year-old gentleman who presented to us with the inability to carry off intercourse without difficulty attaining erection on stimulation for the past two years. He had a history of left undescended testis since birth, for which he underwent left orchidopexy 20 years ago. An ultrasound of the pelvis showed an oval hypoechoic-shaped heterogeneous mass in the right mid-inguinal canal. Relevant blood investigations showed a deranged hormonal profile. He then underwent an uneventful right radical orchiectomy, histopathology of which was consistent with Leydig cell tumor. CLINICAL DISCUSSION: LCT with a history of bilateral cryptorchidism has rarely been reported. This case highlights its clinical presentation, management, and further follow-up in such patients. CONCLUSION: Bilateral congenital cryptorchidism may be associated with Leydig cell tumor years later in life hence long-term follow-up is required for these patients. The clinical presentation of these tumors may vary among individuals. Any change in physical appearance, hormonal assay, and imaging studies should promptly be followed for possible surgical resection and close monitoring.
