SummaryOvarian steroid cell tumors are very rare functioning sex-cord stromal tumors. They comprise <0.1% of all ovarian tumors. Previously designated as lipoid cell tumors, one-third of these tumors are considered malignant with the mean age of presentation at around 40 years. We present a case of a 28-year-old female with 2-year history of hirsutism, virilization, and amenorrhea. She was diagnosed with left ovarian tumor, for which she underwent left salpingo-oophorectomy. Histopathology revealed not otherwise specified subtype of steroid cell tumors. The patient resumed menses 2 months after the features of masculinization regressed. Within 1 year of surgery, the patient successfully conceived a full-term baby without any complications. In a young female, the neoplastic etiology of a rapid virilization or menses changing should always be kept in mind. Though commonly observed in adult females, steroid cell tumors have very good surgical outcomes if age at presentation is less and tumor is unilateral, and there are no evidences of bilateral malignancy. Bilateral salpingo-oophorectomy is not required.Learning points In a case of severe rapid hirsutism and virilization with serum testosterone level more than 200 ng/dl or more than threefold of the normal range, neoplastic conditions should always be suspected.Steroid cell tumor in young women without evidence of malignancy on histopathology has excellent surgical outcomes.Unilateral salpingo-oophorectomy is the surgery of choice.As the frequency of bilateralism is only 6%, prophylactic unaffected side oophorectomy need not be done.

Background: The adipocyte derived hormone, leptin, has cytokine like function and may mediate the effects of starvation on immunity. Mice with congenital leptin deficiency (ob/ob) have small hypocellular thymuses and impaired cellular immunity. In humans leptin influences the differentiation of naïve and memory cells in vitro, and genetic leptin deficiency has been associated with an ill defined susceptibility to infection. Aims: To describe the in vivo relation of leptin and immune function in children. Methods: Fasting plasma leptin concentrations, immune function (T and B cell mediated vaccine responses and delayed type hypersensitivity), and mucosal function (dual sugar permeability test and salivary sIgA concentrations) were measured in a cohort of 472 moderately undernourished rural Gambian children. Results: Leptin concentrations correlated with body fat assessed by mid upper arm circumference or BMI for age Z scores, and were very low compared to well nourished European norms (males 1.8 v 11.1 ng/ml; females 2.4 v 13.8 ng/ml). No detectable relations were found between leptin concentrations and any of the measures of immune or mucosal function. Conclusions: The data confirm that leptin acts as a peripheral signal of energy restriction, but do not support an association between fasting plasma leptin levels and immune function in children of this age.
