HighlightsThe prevalence of rudimentary uterine horn ectopic pregnancy is very low (1 in 76 000–150 000 pregnancies).Early diagnosis of a rudimentary horn pregnancy is the key to successful management.The medical treatment may be a successful adjuvant therapy to surgical removal in asymptomatic women.

e travelling salesperson problem with hotel selection (TSPHS) is a recently proposed variant of the travelling salesperson problem (TSP). Currently, the approach that finds the best solutions is a memetic algorithm. However, this approach is unsuitable for applications that require very short computation times. In this paper, a new set-partitioning formulation is presented along with a simple but powerful metaheuristic for the TSPHS. e algorithm is able to obtain very competitive results while remaining at least one order of magnitude faster than the best-performing method so far. e parameters of the metaheuristic were carefully tuned by means of an extensive statistical experiment.

Case 2 was a woman aged 67 with ovarian multilocular-solid cyst of 30 9 27 cm with solid "honeycomb" component of 12 9 13 cm, color score 4 (Figure 2). CA 125 was 56.6 UI/ml. Histological diagnosis was a clear cell adenocarcinoma (Figure 3). Case 3 was a woman aged 85 with ovarian multilocular-solid cyst of 30 9 27 cm, with solid "honeycomb" component of 15 9 12 cm, color score 3 (Figure 4). CA 125 was 30 UI/ml. Histological diagnosis was mucinous cystadenoma (Figure 4). Case 4 was a woman aged 85 with ovarian multilocular-solid cyst of 30 9 27 cm, with solid component of 6 9 3 cm, color score 3 (Figure 5). CA 125 was 30 UI/ ml. Histological diagnosis was low grade serous adenocarcinoma. The last 2 cases were postmenopausal women in whom US showed solid masses of about 6 cm, colour score 3 (Figure 6). Case 5 was a woman aged 53 in hormonal therapy for breast cancer. Case 6 was a woman aged 63 with a family history of ovarian cancer. Histological diagnosis was metastasis of breast cancer in the first case and ovarian fibromas in the second case (Figure 7).
