Cystic papillary pancreatic tumor is an infrequent neoplasm of unknown origin which is presented almost exclusively in young women. It is characterized by an anodyne clinical symptomatology with it frequently treated as an accidental finding. Ultrasonography and computerized axial tomography have a priority role in the study of this entity but the definitive diagnosis is based on the histologic findings. The treatment of choice is surgical removal and although it is a malignant tumor, good evolution is observed with recurrence not being expected. Two new cases of cystic papillary tumor are presented comparing the ultrasonographic appearance of the same with other pancreatic cystic neoplasms. Although the ultrasonographic findings are not characteristic they may be suggestive of papillary tumor.

Background: Clear cell ovarian carcinoma (CCOC) is a type of epithelial ovarian cancer, representing 5-11% of ovarian cancers. CCOCs tend to occur in the fifth to seventh decades of life, with only 10% of cases occurring in the fourth decade. On the other side, papillary thyroid carcinoma is the most common histology type of thyroid carcinoma and is associated with locoregional spread.

Introduction: Digital papillary adenocarcinoma (DPAC) is a rare malignant tumour of the sweat glands, usually in the digits. It has a high rate of recurrence and metastasis, yet there's a lack of guidelines for its diagnosis and management. Therefore, this report aims to evaluate procedures that provide the best outcomes, which will help create a consensus for its management.

Background: Traditional teaching dictated that patients with recurrent thyroid cysts undergo excision owing to a 12% risk malignancy. Ultrasound evaluation now determines management of these patients augmented by fine needle biopsy. In UK, a non-diagnostic category for thyroid cysts (Thy1c) exists, whereas the Bethesda system combines 'non-diagnostic-cyst fluid only' into Category I along with paucicellular and acellular results.

Background: Rathke cleft cysts (RCCs) are benign sellar/suprasellar lesions that result from mucin-secreting vestigial remnants within the pars intermedia of the pituitary gland. When symptomatic, they can present with retro-orbital headaches, visual field defects, and/or pituitary dysfunction.
Observations: A 35-year-old female presented with subacute retro-orbital headache, right ptosis, and blurred vision.

Stanford Medical Center; Stanford, CA, United States of America.
Gamna-Gandy (GG) bodies are sclerosiderotic nodules composed of iron pigment and calcium, that have been described predominantly in the spleens of patients with sickle cell disease. Their formal depiction in the kidney is mainly limited to case reports and small series. We aimed to investigate the incidence of GG bodies and associated clinicopathologic features in consecutive nephrectomies performed for renal tumors.
