Childhood acute lymphoblastic leukemia (ALL) is the most common childhood malignancy, accounting for 25% of pediatric cancers. Relapse occurs in 15–20% of cases, and only 2–6% has extramedullary localization, with the central nervous system being the main site. Relapse of ALL in gynecological organs is extremely rare and it manifests with profuse vaginal bleeding or nonspecific symptoms such as abdominal pain. Read More

The incidence of thyroid nodules in the pediatric population is low, ranging from approximately 0.5% to 5%. The risk of malignancy is higher than in adults. ultrasound is considered the “gold standard” for an accurate and reliable evaluation of thyroid nodules, identifying predictors of malignancy. Epidermoid cysts (EC) can be distinguished from dermoid cysts, and EC are extremely rare with fewer than 20 cases reported, only two of them involved pediatric patients. Due to the content of keratin and squamous cells, the epidermoid cyst may present a solid ultrasound appearance with echogenic punctiform images that could simulate calcifications, even in the color Doppler examination it could present scintillation artifact. Therefore, cytologic evaluation is essential in the diagnosis, and shows sheets of anucleated squamous cells mixed with few nucleated ones with absence of cellular atypia, granuloma or thyroid epithelial cells Read More
